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
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 Locators 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
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 Locators 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 Locators 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
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.
16
With the combination of all these benefits, you
just cant help smiling when using the Locator
Implant Attachment system
17
The triangular shaped internal drive design in
the Locator Abutment is a very low profile and
has minimal effect on wear of the nylon male.
18
The matching Locator Abutment Driver is used to
place the Locator Abutment. As with all PerioSeal
abutments there is no need to torque them. HAND
TIGHTEN THEM ONLY
19
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
The Locator Core Tool performs the three
different operations of nylon male removal, new
male insertion into the metal denture cap, and
abutment placement.
24
The following step by step procedures and
clinical case were photographed and
provided courtesy of Dr. Allen Schneider, from
his private practice in Springfield, Virginia.
25
This acrylic mandibular model is used to
demonstrate the restoration of two externally
hexed implants that have been placed in an
elevated location at the same level as the
surrounding gingival.
26
The Locator Abutment Driver is the gold colored
portion of the Locator Core Tool, which also
contains a Male Removal Tool, and a Male Seating
Tool.
27
The abutment driver is used by hand to insert the
abutment into the implant and tighten it firmly.
28
The backside of the Locator Abutment Driver has
an internal hex that is designed for the
tightening the abutment.
29
Hand tightening will prevent the abutments
from loosening.
30
The Locator Abutments maintain a very low
profile, even on implants placed as shallow as
those used in this demonstration model.
31
Snap a Locator Parallel Post onto each abutment
to check that the implants are parallel.
32
If the implants are not parallel, Zest Anchors
provides an Alignment Pin and Angle
Measurement Guide that can be used to easily
determine the degree of divergence of an implant
fixture.
33
The Alignment Pin has four different thread
patterns that will match most types of implants
on the market. Insert an Alignment Pin into each
divergent implant.
34
The Angle Measurement Guide is held level with
the path of prosthesis insertion to determine
whether the degree of divergence for each implant
will require the use of a Locator white or green
Replacement Male.
35
A Locator Impression Coping and Abutment Analog
are used for the indirect processing of the
Denture Cap Male by the dental laboratory.
36
A Locator Impression Coping and Abutment Analog
are used for the indirect processing of the
Denture Cap Male by the dental laboratory.
37
Place a Locator Impression Coping (8505) onto
each Locator Implant Abutment.
38
Inject a light body, vinyl impression material
around each Impression Coping.
39
Take a complete impression using a firm body
impression material.
40
The Locator Impression Coping is designed with
minimum retention to be picked up with the
completed impression.
41
The Locator Abutment Analog is designed with a
precise fit into the Locator Impression
Coping, allowing for an accurate transfer to the
working model.
42
Snap a Locator Abutment Analog into each
Impression Coping making sure they are fully
seated.
43
The master cast is poured, incorporating the
Locator Abutment Analogs.
44
The Abutment Analog in the master cast
replicates the exact position of the Locator
Abutment in the acrylic model.
45
Place a White Block-Out Spacer over the head of
each Abutment Analog. The spacer is used to block
out the immediate area surrounding the Locator
Implant Abutment.
46
Snap a Locator Black Processing Cap Male onto
each analog, leaving the white Block-Out Spacer
beneath it.
47
Process the males into the denture base with
light cured or self-curing acrylic resin.
48
Discard the white spacers. Damage to the final
male can be avoided by polishing the denture base
before changing the black processing males to the
final nylon retention liners.
49
Use the Male Removal Tool or an explorer to
remove the Black Processing Male from the metal
denture cap.
50
The hook on the end of the curved tool is used to
catch the side of the black plastic material and
pull it out of the metal housing.
51
The nylon Locator Replacement Male replaces the
black Processing Male for the final seating of
the overdenture.
52
The Male Seating Tool is used to place the nylon
Replacement Male into the empty metal denture cap.
53
The Replacement Male should seat securely into
place, level with the rim of the cap.
54
Check the fit of the attachment retained
overdenture on the master cast before delivering
it to the dental office.
55
The indirect processing of the Locator Male into
the denture by the dental laboratory produces the
same accurate result as a direct chairside
pickup.
56
The self-aligning ability of the Locator Implant
Attachment aids the patient in orienting
their prosthesis, which is vital with the
existence of a severely resorped mandibular
ridge.
57
This patient that was referred to Dr. Schneider
has two externally hexed mandibular implants. The
gingival level surrounding the implants was very
shallow, as can be seen by the hex of the implant
extending above the crest of the tissue on the
patients right side.
58
With limited space available, use of the shortest
attachment possible was indicated. Locator
abutments with lowest tissue cuff height were
placed using the abutment driver.
59
When placing multiple attachments, snap a
Parallel Post into each seated Locator Abutment
to check the parallelism between implants.
60
For this patient, the Locator Male was placed
into the overdenture using a chairside
procedure. First a White Block-Out Spacer was
placed over the head of each Locator Abutment.
Then a Locator Cap with Black Processing Male is
snapped onto each Locator Implant
Abutment, leaving the white spacer beneath it.
61
Recesses were prepared into the denture base to
accommodate the Locator Males.
62
Light-cured acrylic resin was injected around the
metal cap of each Processing Cap Male. The resin
can also be injected through an access hole in
the denture.
63
The denture was inserted into position in the
oral cavity, maintaining the denture in a
passive condition, without compression of the
soft tissue, while curing with the light.
64
An additional brief curing time on the lingual
side of the denture will assure fixation of the
Locator Male into the denture base.
65
The White Block-Out Spacers remained in place
when the denture was removed.
66
The White Spacers are easily removed with an
explorer instrument. Use a bur to remove excess
acrylic, and polish the denture base before
changing to the final nylon male.
67
The Locator Core Tool contains three tools in
one. Start with the fully assembled tool for the
procedure of replacing the black processing males
with the final nylon male.
68
The curved Male Removal Tool portion of the
Locator Core Tool has a hook on the end of it.
69
Wedge the hook down into the bottom corner of the
black plastic male.
70
The hooked end of the Male Removal Tool will
catch the side of the black plastic material and
pull it straight up and out of the metal housing.
71
Remove the curved section of the Locator Core
Tool to access the Male Seating Tool portion.
72
Place a nylon Locator Replacement Male onto the
end of the Male Seating Tool.
73
Use the tool to firmly push the final Locator
Male nylon liner into the metal Denture Cap.
74
The overdenture was then ready for delivery to
the patient, and final adjustments.
75
A beautiful aesthetic result was achieved for
this patient using the low profile Locator
Attachments to retain the overdenture.
76
With the incredible retention of Locator
overdentures, dont be surprised if your patients
take up a new hobby like this!
