Locator Implant Attachment

Locator Implant Attachment

Locator Implant Abutment Instructions

Indications

The Locator Implant Attachment System is designed for use with overdentures or partial dentures, retained in whole or in part by endosseous implants in the mandibular or maxilla.

Contraindications

Not appropriate where a totally rigid connection is required.

Sterilization

All components and instruments are supplied NON-STERILE. Implant abutments and metal instruments may be sterilized following standard clinical procedures prior to use.

Single-Use Devices

  • Locator Males: The inadvertent re-use of Locator nylon males could cause loss of retention for the overdenture due to wear from previous use or damage during removal with the Locator Core Tool.
  • Locator Abutments: The inadvertent re-use of Locator abutments could contain patient contamination build-up and subsequent wear of the retention bands. This would result in the device to perform with improper fit and function which would result in loss of retention for the prosthesis.

Features

Lowest Vertical Height: The total height of the lowest Locator Attachment (abutment plus male) is only 3.17mm on an externally hexed implant, and 2.73mm on a non-hexed implant.

Locating Design: Self Locating design allows a patient to easily seat their overdenture without the need for accurate alignment of the attachment components.

Retention inside and outside: The unique Dual Retention innovation provides the LOCATOR attachment with greater retention surface area than ever before available with other attachments. A combination of inside and outside retention ensures the longest lasting performance.
Use with non-parallel implants: Angle correction nylon inserts allow easy correction of divergent implants.

Rotational pivoting action: The design of the pivoting LOCATOR male allows a resilient connection for the prosthesis without any resulting loss of retention. The retentive nylon male remains completely in contact with the female socket while its metal denture cap as a full range of rotation movement over the male.

Patient Care

Good oral hygiene is vital to implant success. The Locator Implant Abutment must be thoroughly cleaned daily. The use of a soft nylon bristle or end-tufted toothbrush, and superfloss to polish the abutments should be taught. A non-abrasive gel toothpaste, and an irrigation system is recommended to keep the socket of the Locator Abutment clean.

Soaking the overdenture is not recommended. For patients who soak their dentures, eat a very gritty diet (salads, spinach, etc), or have health issues (like acid reflux), please instruct the patient to brush the attachments with mild dish soap and water. This will keep the nylon attachments smooth and reduce excessive wear on the implant abutments.

Patients should maintain a three to four month recall for cleaning and implant evaluation. Replace nylon males if they have a build-up of abrasive calculus; this will cause premature wear on the implant abutment. Check for a reline; a relined prosthesis provides prosthesis stability and reduces the wear on the attachment.

The sulcus area around the implant abutment is a primary area of concern. Use plastic instruments for scaling the abutments. Do not use metal instruments which may create scratches on the abutment surface. Examine patients for signs of inflammation around the implant abutments, and for implant mobility. Use the Locator Abutment Driver to make sure the Locator Implant Abutment is tight before dismissal.

How to change the Locator Male

  1. The Locator Core Tool, which contains a Locator Male Removal Tool and Locator Male Seating Tool, is used to remove the existing nylon male from the metal denture cap and replace it with a new Locator Replacement Male.
  2. Use the Male Removal Tool to remove the nylon male from the denture cap.
  3. The Male Seating Tool is used to firmly push a Replacement Male into the empty metal denture cap. The replacement male must seat securely into place, level with the rim of the cap.

NOTE: The replacement male will not stay on the tool when it is turned upside down due to the varying sizes of males available. It is best to hold the denture with the base side down and snap the male into the metal denture cap.

Reline and Rebase

  1. Remove each existing nylon male from its metal denture cap following the steps in “How to Change the Locator Male.” Replace them with Black Processing Males. The built in spacer of the Black Processing Male will maintain the overdenture in its upper level of vertical resiliency during the reline process.
  2. Take a reline impression using the existing overdenture as a tray. The Black Processing Males will engage the Locator Implant Abutments and hold the prosthesis in place while the impression material sets.
  3. After the impression is withdrawn, snap a Locator Abutment Analogue into each Black Processing Male and pour a master model.
  4. Process the reline following the same steps as outlined in “Locator Male Placement by the Laboratory.”
  5. After processing the reline and polishing the denture base, replace the Black Processing Males with the final Locator Replacement Males.

Ceka Attachments – Servicing, Repairs & Relines

Repair and Servicing to Removable Partial Dentures Retained by Ceka Attachments

Determination of reline or rebase–Bilateral free end Prosthesis. Determine the need for a reline by placing fingers over the Ceka attachments and at the same time apply light pressure to the free-end saddle. If hinging is observed, a reline is necessary.

Alternative Technique: Place 23 gauge soft wax (approximately .5mm) on the tissue bearing side of the saddles. Place the 694B (M3) or RE0096 (M2) spacer over the male spring pin. Seat the removable partial denture. Apply finger pressure directly over the attachments. Do NOT have the patient close and bite. Remove the prosthesis and inspect the 23 gauge soft wax.

  • If there is evidence of the tissue contact with the soft wax, do not reline as the resorption is less than 0.5mm.
  • If there is no evidence of tissue contact with the soft wax, the resorption is greater than 0.5mm and a reline of the prosthesis should be completed.

Step One: Determining the correct size of Ceka Spring Pins

View the patients records, or check the actual spring pin in the prosthesis, to determine whether the case was fabricated using the M3 or M2 spring pin. (Ceka Spring Pin listing).

Repair and Servicing 1

Ceka Sizer Kit

Repair and Servicing 2

In the mouth

Use the Ceka Sizer to determine the correct male spring pin size/diameter that will provide maximum retention. Simply start with the 1.88 and insert each numbered sizer until the best size is determined.

Repair and Servicing 3
Repair and Servicing 4

Removing/replacing a spring pin in the patients mouth:

  • ONLY USE THE “CROSS-HAIR” END OF THE A1 TOOL, OR USE THE REH5 TOOL
  • Clean the spring pin with compressed air to allow for a perfect fit of the cross hairs of the tool between segments. This will prevent breaking, or torquing, of the segments when loosening or unthreading the pin.
  • Remove the spring pin by unthreading to the LEFT.

Replacing a removable spring pin with broken segments:

  • Reduce the remaining parts of the segments to the same height by grinding.
  • Make a groove in the spring pin base with a saw-toothed burr
  • Reduce the blade of a small screwdriver from hardened steel to the length and width of the groove. Unthread the remaining part of the spring pin strongly but carefully from the base ring or retention part by turning it to the LEFT.
  • Check if the threads of the base ring, or retention part, were damaged before screwing in a new spring pin.
  • Secure the spring pin with Ceka Bond adhesive.

Repair and Servicing 5Repair and Servicing 6

 

If the existing spring pin is not providing sufficient retention, it is quite possible the female attachment has wear, and an oversized spring pin is needed. The retention of the removable spring pin may be checked by threading into an impression piece (H14, RE H14) and seating it in the female.

In case of a small loss of retention, the head (bottom, or “cross hairs”) of the spring pin may be slightly increased.

  • Use only the activating blade of the A1 or A1L tool to increase retention on all Ceka spring pins.
  • Press the activating blade of the A1 tool vertically, progressively and crosswise between the 4 segments of the spring pin (see picture).
  • Activate step-by-step and check if the spring pin has attained adequate retention
  • Never make lateral or bending movements, as one or more spring pin segments might fracture

In case of larger losses of retention, use the Ceka Sizer to determine the appropriate spring pin for the existing female. Reasons for losses of retention are as follows:

  • Frequent activation of the spring pin will reduce the elasticity of the alloy
  • Divergent or non-parallel attachments will cause loss of retention and premature wear on the female
  • If retention is not achieved because the spring pin does not fully snap into the female, the retention zone of the spring pin must be lowered, e.g. by using a longer spring pin (RE0031L or 694CL).

Step Two: Impression Taking

When parts are listed in the following sections, we will be referring to the M3 series. The M2 series has the same product number, only with a “RE” prefix (view Ceka components).

Repair and Servicing 10

Create the male impression analogue by threading a spring pin, or (H1) working dummy pin, into the H14 using the A1 or REH5 tool. Using an incorrect tool (other than the A1 or H5) will spread the retention parts of the spring pin and not allow the male to seat in the female.

Standard Size Spring Pin

If the standard size spring pin provides adequate retention:

Repair and Servicing 11Thread either the 694C spring pin or H1 working dummy spring pin into the H14. The H1 has a built in space maintainer; if using the 694C spring pin, use the 694B space maintainer (shown).

Oversized Spring Pin

If an oversized male spring pin is needed to provide adequate retention in the female:

Repair and Servicing 12Thread the appropriate oversized spring pin (195, 202, or 209) into the H14. When using an oversized spring pin, the 694B space maintainer must be used (shown).

Repair and Servicing 13

Place the male impression analogue (with spring pin and spacer, or H1) into the existing female in the mouth. Block out any undercuts beneath the Ceka female. Make sure the H14 is fully seated in the female. Take an impression. The H14 will be indexed in the impression (note the use of the spacer).

Repair and Servicing 17A. Technique for Oversized Spring Pins

Using either the A1 or REH5 tools, unthread the oversized (195, 202, or 209) spring pin from the H14. Thread the H1 working spring pin into the H14 (the H1 is a standard size spring pin, and thus will fit the H13 female analogue). Re-seat the H14 with the H1 dummy working spring pin in the impression.

B. Oversized and Standard Spring Pin cases

Repair and Servicing 18
Repair and Servicing 19
Repair and Servicing 20

After re-seating the H14 analogue in the impression, snap the H13 female analogue over the standard size spring pin in the H14. If the 694C is being used instead of the H1, you must use the 694B space maintainer. Pour up the master model, separate from the impression. The H13 female analogue will be in the model, exactly where the females are in the mouth.

Step Four: Process the Retention Cap into the Prosthesis

The H1 (or the 694C and 694B) is unthreaded from the H14 in the impression. The H1 (or the 694C and 694B) is threaded into the retention cap of choice and is placed into the H13 on the master cast.

If a reline is being completed, process the reline over the retention cap to incorporate into the prosthesis.

If a repair is being completed, please view the chairside procedure.

Laboratory Procedure

Remove all impression material from the immediate area of the Ceka male spring pins with a small Bard Parker blade. Place the 694B space maintainers over the Ceka male spring pins and snap the Ceka H13 accessory over each male spring pin. The opening on the side of Ceka H13 acts as a check point for the exact location of the male spring pin in the Ceka H13 accessory and should be blocked out with soft wax to prevent penetration of the plaster into the segments of the male spring pins. Cast the working model.

For accurate relining, a reline jig or clamp is recommended. Mount the working model in the reline clamp using an occlusal plaster register or matrix. The teeth should be shallowly impressed (2mm to 3mm) in the plaster. The partial denture may now be removed to expose the tops of the Ceka H13 accessories which act as the Ceka females. These provide accurate horizontal and vertical location during processing. The impression material is now removed and sufficient acrylic resin is ground away from the base of the partial denture. The working model and substitute females now are painted with a separating medium. Replace the Ceka male spring pins with the correct Ceka dummy male spring pins–H1. Fill the metal sleeves in the framework surrounding the Ceka male spring pins with silicone rubber to prevent acrylic resin penetration.

The metal frame should be prevented from moving during processing by fixing the major connector to the working model with a small amount of stone. Place a thin film of vaseline over the acrylic resin parts and artificial teeth to prevent any new acrylic resin from sticking to places where it is not required. Place the partial denture in the occlusal incisal register and pour the acrylic resin into place, then process under pressure. When set, remove the partial denture from the working model, being careful not to damage or break the working model. Finish and polish the partial denture. Finally, replace the Ceka dummy male spring pins (H1) with either the original or new Ceka male spring pins. The male spring pins should be threaded into the retention part with Ceka Bond to prevent it from unthreading.

Reseating or Replacing of a Ceka AKS Retention Part in Acrylic Resin

Chairside Procedure

A Ceka male spring pin is threaded into an AKS retention part. The small 694B space maintainers coated with vaseline are positioned over the Ceka male spring pin. Snap the male spring pin into the Ceka female. Block out the area beneath Ceka female in the mouth. Remove sufficient acrylic resin from the partial denture to allow it to be accurately and fully seated underneath the Ceka retention part in the mouth without touching the Ceka attachment. It is always recommended that a small hole be cut on the lingual of the prosthesis as an escape vent for any excess self-curing resin.

Seat the Ceka attachment with small space maintainers-–694B–correctly in the partial denture in the patient’s mouth and hold it in place with fingers while carefully self-curing the Ceka AKS retention part in the partial denture, using the brush liquid-powder technique. Do not have the patient bite, or come to full occlusion, as this can cause tissue compression in the posterior and thus attachment misalignment. After the self-cure resin is set, remove the partial denture and finish. Discard the spacer.

Repair and Servicing 14
Repair and Servicing 24

Laboratory Procedure (if necessary)

Snap the H13 female analogue over the Ceka male spring pin. To avoid stone flowing between the segments of the male spring pin, fill the opening in the Ceka H13 female analogue and the sleeve of the metal frame around the Ceka attachment with silicone rubber. Use the small space maintainer (694B) with Ceka resilient attachments. Block out the undercuts of the saddles and pour a working model. Remove the Ceka AKS retention component and male spring pin from the partial denture. The retention part may then be re-attached using self cure resin.

BPD Plastic Dovetail Instructions

BPD Plastic Dovetail Instructions

BPD Attachment

Summary

The BPD is an improved design for a universal plastic pattern.

The simple to use plastic dovetail intracoronal attachment can be used for:

  • Removable Partial Dentures: Intracoronal semi-precision slide attachment.  Rigid attachment (always use a retentive clasp arm) with friction (not adjustable) retention.
  • Bridgework: non-parallel abutments and segmented constructions.
  • Inside of female rounded to facilitate devesting and avoid attachment wear
  • Built in paralleling mandrels for both male and female.

The built in mandrel on the male and female provides the convenience of using the BPD in a traditional manner, or inverting it.

By inverting the BPD,

  • no metal is shown on the occlusal surface for better esthetics.
  • placing the male extracoronal of the crown does not require additional space, or abutment reduction.
  • On mandibular implant cases, the female tends to follow the taper of the male and allow for some flexing of the lower jaw.
BPD Plastic Dovetail Instructions1
BPD Plastic Dovetail Instructions2
BPD Plastic Dovetail Instructions3
BPD Plastic Dovetail Instructions4

The patterns are produced in a clean burnout plastic. The reduced size provides wider application, better abutment contours, and improved esthetics. Taper ensures easy insertion and well defined proximal plates provide increased stability. A universal attachment.

Assembly and Fabrication

Bridgework–Traditional (female on abutment, male in pontic)

1. Survey the model to determine the position of the Plastic Dovetail. Wax all abutments, but open a channel or box on the abutment to allow space for the female attachment within the contours of the crown.

2. Place the male mandrel in the surveyor. Cut the mandrel from the bottom of the female. Place the female on the male. Incorporate the female in to the abutment wax-up. Keep the entire female within the correct contour for the abutment tooth.

3. Carefully remove the male from the female, and complete waxing of abutments to proper contour. Keep the inside of the female free from wax.

4. Any excess of the female pattern above the occlusal of the abutment is left remaining. This will be reduced after casting. Use a harder alloy for the abutment crown to avoid the female attachment wearing.

5. Sprue and remove the abutment patterns. Invest, being sure to completely fill the inside of the female with investment without air bubbles. A two stage investment procedue is recommended.

6. Burnout for plastic components requires two stages:

  • To assure a clean and complete burnout of the plastic attachments, use a Slow rate of temperature rise to 600°F (316°C) and hold for 30 minutes.
  • Complete the burnout procedure by following the alloy manufacturer’s instructions.

7. Finish the casting. Reduce any excessive height of the attachment at this time. Remove any bubbles from the inside of the female.

8. For traditional applications, insert the plastic male into the cast female. If the male pattern will not fully seat, heat the cast abutment prior to seating the male pattern. The heat will soften the male pattern so it will contour to the female.

9. Seat the male pattern in the female and wax the adjacent pontics or abutments to the male.

10. Cut off the mandrel from the male with a hot spatula. Sprue, invest and cast the units.

11. Finish the castings and the male. If the fit is too tight and the male will not fully seat, use one of the following procedures to achieve proper seating.

  • Strip the male for 15 – 20 seconds, or until a positive seating is aquired.
  • Paint Liquid Colloidal Graphite on the male, dry it with a gentle stream of air, and slide it in and out of the female until a complete seating is achieved.
  • Gently polish the male until complete seating is achieved.

Bridgework–Inverted (male on abutment, female in pontic)

1. Survey the model to determine the position of the Plastic Dovetail. Wax all abutments.

2. Place the female mandrel in the surveyor. Cut the mandrel from the bottom of the male. Place the male into the female. Incorporate the male in to the abutment wax-up.

3. Carefully remove the female from the male, and complete waxing of abutments to proper contour. Cut the mandrel off the female, and position inside the pontic. Keep the inside of the female free from wax.

4. Any excess of the male pattern above the occlusal of the abutment is left remaining. This will be reduced after casting. Use a harder alloy for the abutment crown to avoid the male attachment wearing.

Removable Partial Denture Procedure (intracoronal attachment)

Steps 1 – 11 are the same as in the Traditional Bridgework technique.

12. Prepare the lingual of the retainer crown for the clasp arm. Eliminate any lingual undercuts and prepare a dimple on the lingual of the crown away from the female with a #3 round bur.

13. Place the male pattern in the female receptacle on crown. Remove the mandrel from the male.

14. Using pattern resin, make clasp arms to the male pattern. Be sure to extend the clasp arm into the dimple. Use an alloy which is softer than that used to cast the attachment female.

15. Block out all undercuts and duplicate the model. Pour a refractory model used to fabricate only the partial frame.

16. Cast the framework in chrome cobalt. Finish the casting.

17. Seat the completed casting on the master model. If the fit is too tight and the male will not fully seat, one of the following steps may be used to achieve proper seating.

  • Strip the casting for 15 – 20 seconds, or until a positive seating is aquired
  • Paint Liquid Colloidal Graphite on the male dry it with a gentle stream of air, and slide it in and out of the female until a complete seating is achieved.
  • Gently polish the male until a complete seating is achieved.

If the fit of the male is too loose, lightly reduce the base of the male with a dis to insure a proper fit.

18. Solder the male/lingual arm assembly to the partial framework using Ceka Sol solder.

19. Process the partial denture over the completed castings in a routine manner

Removable Partial Denture Procedure (extracoronal attachment)

1. The paralleling mandrel on the female is used to wax the male, extracoronally, on the abutment wax pattern. If the attachment is too long, shorten both the male and female from the gingival aspect. The male is inverted, or “upside down”.

2. Carefully remove the female from the male pattern.

3. Complete waxing the abutments for proper contour. Prevent the wax from flowing onto any mating surface of the male pattern.

4. Remove the paralleling mandrel from the bottom of the female. Replace the female onto the male pattern and wax the female to the adjoining abutment/pontic.

5. Sprue and remove the abutment patterns. Invest, being sure to completely fill the inside of the female with investment without air bubbles

6. Burnout and cast. Burnout for plastic components requires two stages:

  • Slow rate of temperature rise to 600°F (316°C) and hold for 30 minutes. This assures a clean and complete burnout of the plastic piece.
  • Complete the burnout procedure by following you alloy manufacturer’s instructions.

7. Remove any bubbles and finish the castings according to Step 14 in the “Removable Partial Denture Procedure (intracoronal attachment)” section.

Patient Care

Good oral hygiene is vital to implant success. The Locator Implant Abutment must be thoroughly cleaned daily. The use of a soft nylon bristle or end-tufted toothbrush, and superfloss to polish the abutments should be taught. A non-abrasive gel toothpaste, and an irrigation system is recommended to keep the socket of the Locator Abutment clean.

Patients should maintain a three to four month recall for cleaning and implant evaluation. The sulcus area around the implant abutment is the primary area of concern. Use plastic instruments for scaling the abutments. Do not use metal instruments which may create scratches on the abutment surface. Examine patients for signs of inflammation around the implant abutments, and for implant mobility. Use the Locator Abutment Driver to make sure the Locator Implant Abutment is tight before dismissal.

How to change the Locator Male

  1. The Locator Core Tool, which contains a Locator Male Removal Tool and Locator Male Seating Tool, is used to remove the existing nylon male from the metal denture cap and replace it with a new Locator Replacement Male.
  2. Use the Male Removal Tool to remove the nylon male from the denture cap.
  3. The Male Seating Tool is used to firmly push a Replacement Male into the empty metal denture cap. The replacement male must seat securely into place, level with the rim of the cap.

NOTE: The replacement male will not stay on the tool when it is turned upside down due to the varying sizes of males available. It is best to hold the denture with the base side down and snap the male into the metal denture cap.

Reline and Rebase

  1. Remove each existing nylon male from its metal denture cap following the steps in “How to Change the Locator Male.” Replace them with Black Processing Males. The built in spacer of the Black Processing Male will maintain the overdenture in its upper level of vertical resiliency during the reline process.
  2. Take a reline impression using the existing overdenture as a tray. The Black Processing Males will engage the Locator Implant Abutments and hold the prosthesis in place while the impression material sets.
  3. After the impression is withdrawn, snap a Locator Abutment Analogue into each Black Processing Male and pour a master model.
  4. Process the reline following the same steps as outlined in “Locator Male Placement by the Laboratory.”
  5. After processing the reline and polishing the denture base, replace the Black Processing Males with the final Locator Replacement Males.

Why use the Processing Spacers?

Horix Hader Bar Instructions1The width of the “tail” of the green processing spacers matches the widest part of a Hader clip. This allows easy insertion and removal of the actual clip, and more importantly provides a “tunnel” that is wide enough for removal and insertion of the prosthesis.

The left side of this picture shows the tunnel created using the processing spacer. The flange of the clip has room to flex out over the height of contour and engage the Hader Bar.

The right side of this picture shows the problems that may be encountered when not using the processing spacer–the clip is locked in acrylic; the flanges of the clip are pressed inward making clip wear very possible, and insertion very difficult or even impossible without breakage. This clip can not expand, or flex outward while going over the height of contour of the bar.

The bottle of protective lacquer must be CLOSED immediately after each use. Air and warm temperatures thicken the protective lacquer, making a chemical bond on the mask surface impossible. Sealing the cap with wax is helpful to preserve the lacquer.

After applying the lacquer, place the prosthesis at room temperature on a dust-free plate in the oven, increasing the temperature to a maximum of 130 C for 10-15 minutes.

Correction-Repair Material

It is possible to correct a defect or tear in the mask. With a defect, such as impression error, a new impression of the appropriate part as well as the model is necessary. Clean the area to be repaired and apply activator liquid. Mix base and activator and apply where necessary on the model. Set the mask in place immediately, cover with a piece of foil, and apply light pressure. Polymerization can be helped by placing the mask in the oven for a few minutes.

Tears can be repaired in a similar manner on the original model.

Storage

Gingivamoll should be stored in a refrigerator at 15C / 60F and should be left at room temperature 30 minutes before use.
