1. Zest Anchors, Inc. is a global leader in the manufacturing of dental attachments.
Their new Locator Overdenture Abutment is on the cutting edge of dental attachment technology

2. The Locator is designed with ease of use and incredible durability for your patient.
It is manufactured with various thread configurations to fit all major brands of implants.

3. alignment of the attachment components.
The Locator Implant Attachment is a supra-gingival attachment connection for endosseous
implants that allows a patient to easily seat their overdenture without the need for accurate
alignment of the attachment components.

4. The Locator attachment features a denture component with a skirt that easily locates the
mating implant abutment. This self-aligning feature of the attachment aids the patient
in seating their prosthesis in a similar manner as a guide plane created by a milled bar.

5. The Locator’s self-aligning feature has the following advantages:
a) Makes it easy for patients to position and correctly seat their overdenture into place.
b) Overcomes patient problems with inserting and removing their overdentures in
as little as one office visit.
c) Eliminates additional wear and the destruction of attachment components from improper seating

6. The Locator has the lowest vertical height of just 3.17mm total
attachment height on an externally hexed implant.

7. This very low profile is a critical advantage where interocclusal space is limited.
The Locator Implant Attachment is a full 1.68mm lower than the next lowest competitive abutment.

8. When comparing the height of the Locator Attachment on the left with other commonly used implant
attachments on the market, the Locator saves from 1.7mm to 3mm of interocclusal space required.

9. angles up to 40 degrees between two divergent implants.
Another advantage of the Locator Implant Attachment is its ability to accommodate
angles up to 40 degrees between two divergent implants.

10. By placing a special green nylon Extended Range Male insert
into the Locator metal denture cap, the divergent angle of the implant
is easily accommodated using the same Locator Abutment that is normally placed.

11. The Locator’s simple technique for handling angulated implants has the following advantages:
a) Allows correction of angles up to 40 degrees between implants without the need to
purchase additional angle correction abutments.
b) Eliminates the difficult procedure of correctly positioning angled abutments.
c) The green Extended Range Male demonstrates the same long-lasting retention.
d) Maintains the lowest vertical height of 3.17mm on external-hex implants.

12. The Locator’s ability to correct angles up to 40 degrees between two divergent implants
surpasses the maximum of 30 degree correction by all O-Ring and Ball and Socket types of attachments.

13. Attachment durability of a very high level is demonstrated by the Locator
Implant Attachment for the following reasons:
a) The patented “dual-retention” design provides approximately twice the amount of retention
surface area than only internal retention attachments.
b) This combination of inside and outside retention ensures long-lasting retention
life for the Locator Attachment.
c) Independent laboratory testing demonstrated 56,000 cycles of function with excellent retention
for the Locator. This is 28 times longer lasting when compared
to ERA Implant Attachment also tested.

14. Test of Retention Loss performed by the independent testing lab.
This chart illustrates the reported results of the Insertion And Extraction
Test of Retention Loss performed by the independent testing lab.

15. The benefit of easy maintenance when using the Locator system is a result of the following:
a) Attachment durability means fewer maintenance office visits.
b) A special 3-in-1 Locator instrument accomplishes all aspects of attachment replacement.
c) The Locator Abutment Driver is compatible with various torque instruments by using a
common .050 inch (1.25mm) hex driver tip.
d) Locator Abutments torqued to 20 Newton centimeters means reduced loosening complications.

19. the working 1.5mm of the Locator Abutment above the gingival level.
Locator abutments are available in tissue cuff heights ranging from 1mm to 6mm.
Order the same height abutment as the tissue cuff measurement taken, which will place
the working 1.5mm of the Locator Abutment above the gingival level.

20. The Locator Male Processing Package consists of a black Processing Cap Male, white full
retention nylon Final Male, a pink light retention Male, and a white Block-Out Spacer
Ring. This package is used for a direct chairside pick-up of the Locator Male.

21. Two additional Locator transfer components are needed for processing of the Locator Male
by the dental laboratory. This is the new lower profile design for the Locator Impression Coping.

22. The Locator Lab Analog is available in both a 4mm diameter (8530) and
a 5mm diameter (8516) for 1 stage and wider diameter implants as shown.

23. new male insertion into the metal denture cap, and abutment placement.
