Work Instruction 

for the Locator ® 

Retentive System 

1. Introduction 

This work instruction serves as an addition 

to the instruction manual for the Locator ® 

abutment. It is intended to provide users 

who are not fully familiar with it with a clear 

instruction of the proper use of the system 

components. 

2. System Description 

The Locator ® retentive system is designed 

for application of implant-retained, mucosasupported 

prosthesis, including mucosa resilient-borne 

full dentures in the maxilla and 

mandible. The individual axes of the implants 

in such cases must not diverge more than 

20° (10° for implants with Ø 3.3mm) or 

more than 40° between any two implants 

(20° for implants with Ø 3.3mm). The selfaligning 

construction of the Locator ® 

retentive system helps the patient to manage 

insertion and seating of the denture. 

Locator ® abutments are available for 

CAMLOG implants with diameters 3.8, 4.3, 

and 5.0 mm in gingival heights 1.0, 2.0, 

3.0 and 4.0 mm. 

The Locator ® abutment with a 3.3 mm 

diameter is avaialble in gingival heights 

1.0, 2.0, and 3.0 mm. 

The Locator ® abutment (gingival height 

1.0 mm) has a total height of 3.3 mm at its 

lowest vertical point, including the retention 

housing and nylon insert. 

This makes the use of the Locator ® system 

possible even in vertically limited spaces.

7. Application 

6 

The divergence of the implant axes 

between two implants must not exceed 

40° (20° per implant). With implants of 

3.3 mm diameter, the divergence must 

not exceed 20° (10° per implant). 

Before selecting the appropriate Locator ® 

abutment the implant diameter and gingival 

height must be known. 

Select the height of the Locator ® abutment 

in relation to the gingival height. The exact 

height of the abutment has been selected 

when the functional area extends 1.5 mm 

above the surrounding tissue. 

The functional area must never be 

positioned below the gingiva level! 

7.1 Locator ® abutment insertion 

Remove the healing cap and clean the inside 

of the implant. Make sure that the contact 

surface between implant and abutment is 

free of bone and soft tissue. This is the only 

way to ensure satisfactory seating of the 

abutment on the implant. 

When inserting the Locator ® abutment into 

the implant, use the driver for Locator ® 

abutment manual or the gold-colored driver 

of the Locator ® core tool. 

Locator ® abutments must be secured 

during insertion into the mouth to 

prevent aspiration (e.g. with dental floss). 

Locator ® abutments with 3.3 mm diameter 

are tightened with a torque of 

20 Ncm. Abutments with 3.8, 4.3, and 

5.0 mm diameters are tightened with a 

torque of 30 Ncm. The abutments must 

be retightened after 5 minutes with the 

respective torque. 

7.2 Measurement of implant axis with 

parallel posts and the angle measurement 

guide 

The black parallel posts are slipped onto the 

inserted abutments until detectable pressure 

is felt. Then use the Locator ® angle measurement 

guide to measure the angles of the 

individual implant abutments. 

Up to an angle of 10° per implant (up to 

20° between two implants) three replacement 

males can be selected: clear: 22.3 N/ 

2270 g, pink: 13.4 N/1365 g, and blue: 

6.7 N/680 g. 

The following replacement males for axial 

divergences of 10° - 20° per implant are 

available (extended range): 

green: 17.8 N/1815 g, and red: 6.7 N/680 g. 

With Ø 3.3 mm implants, these males must 

not be used!

7.3 Incorporation of the retention 

housing 

The placement of the retention housing (supplied 

in each laboratory set) can be done either 

in the dental laboratory or chairside. 

Tip: A metal cast strengthens the stability 

of the denture. 

7.3.1 Fabrication of a new denture with 

Locator ® components 

The Locator ® components are directly 

incorporated into the new denture during 

processing. 

Insert the Locator ® abutments of matched 

diameters and gingival heights in the manner 

described in 7.1 "Locator ® abutment insertion" 

on page 6.

Chairside: 

Place a Locator ® impression cap on each 

Locator ® abutment for the functional 

impression. Make sure that the impression 

cap is properly seated during the procedure. 

Use a firm impression material (e.g. polyether 

or silicone) to ensure that the impression cap 

will remain securely in the impression. 

In the dental lab: 

After the impression is taken, place the 

analogs (Ø 4.0 mm or Ø 5.0 mm) into the 

impression caps and fabricate the master 

cast. 

After the master cast is finished, place the 

white block-out spacer (supplied with the 

male processing package) over the functional 

areas of the Locator ® analogs to prevent 

acrylic from penetrating into the retention 

housing. 

Mount the retention housings with the black 

processing replacement male on each analog 

over the previously inserted block-out spacer 

until pressure is felt. The black processing 

replacement male will ensure both secure 

seating for the retention housing and 

resilience. 

Selection of matching analogs

Undercuts between the retention housing 

and surrounding tissue which the blockout 

spacer does not reach must be blocked 

out. Do not allow any acrylic to enter 

the retention housing during processing!

Insertion of the replacement males 

After completion of the denture, remove the 

white block-out spacer. 

Before insertion into the mouth, replace the 

black processing replacement males with 

respective colored replacement males with 

the aid of the Locator ® core tool. 

Insert the grip on the tip into the black 

processing replacement male and pull it out 

from the retention housing. 

With the seating tool of the Locator ® core 

tool (middle piece) insert the appropriate 

replacement male into the empty retention 

housing, to match the angle and the desired 

retentive force.

The replacement males have no friction 

on the seating tool. Therefore keep the 

seating tool perpendicular and insert the 

replacement male from basal direction. 

7.3.2 Adjusting an existing denture 

with Locator ® components 

Locator ® components can be incorporated 

into an existing full denture. 

Insert the Locator ® abutments of matched 

diameters and gingival heights in the manner 

described in 7.1 "Locator ® abutment insertion" 

on page 6. 


during insertion in the mouth to prevent 









Chairside: 

Place a Locator ® impression cap on each 

Locator ® abutment for the functional 

impression. Make sure that the impression 

cap is properly seated during the procedure. 

Relieve the existing denture in the areas of 

the impression caps. 

The impression caps mounted on the 

Locator ® abutments should not touch the 

denture during the oral try-in. 

In the case of a small denture base, it is also 

possible to take an impression with retention 

housings with the black processing replacement 

males. Be aware of the reduced retention 

potential in the impression material. 

Take the impression with the relieved denture 

directly over the impression caps. Use only an

appropriate impression material (e.g. 

polyether or silicone) to ensure that the 

impression caps will remain securely in the 

impression. 


The matching analog is selected as described 

in the diagram "In the dental lab: Selection 

of matching analogs" on page 7, and 

inserted into the impression caps in the 

impression. Fabricate the master cast and 

ensure the fixation of the defined position 

and occlusal height of the denture and 

occlusal plane. 

After the master cast is finished, place the 

white block-out spacer (supplied with the 

male processing package) over the functional 

areas of the Locator ® analogs to prevent 

acrylic from penetrating into the retention 

housing. 

Mount the retention housing with the black 

processing replacement male over the 

previously inserted block-out spacer until 

pressure is felt. The black processing replacement 

male will ensure both secure seating 

for the retention housing and resilience.

Do cure the retention housings into the relieved 

denture base. 

After the denture has been finished and 

polished, remove the black processing replacement 

males as described in "Insertion of 

the replacement males" on page 8, and 

exchange them with the matching replacement 

males. 

Insert the finished denture and check the 

occlusion. 

7.3.3 Adjusting an existing denture 

with Locator ® components in the 

dentist’s office 

Locator ® components can also be incorporated 

into an existing full denture in the dentist's 

office. Locator ® abutments of matched 

diameters and gingival heights are inserted in 

the manner described in 7.1 "Locator ® abutment 

insertion" on page 6.

Carefully relieve the denture at the intended 

area for the retention housings and then 

perforate it above the housings (as a release 

for excess acrylic and for checking). Grind the 

denture area intended for the retention 

housings sufficiently to permit the inserted 

denture to be seated over the housings 

without making contact. Any contact can 

alter the proper fit of the denture. 

To cure the retention housings, apply selfcuring 

acrylic and process it in accordance 

with manufacturer instructions. Apply a 

small amount into the relieved areas in the 

denture and also apply some to the retention 

housings as well. 

Remove the denture from the patient's mouth 

after the acrylic has cured, remove excess 

acrylic, and polish. 

Remove the black processing replacement 

males as described in "Insertion of the 

replacement males" on page 8, and exchange 

them with the according replacement males.

7.4 Exchange of the replacement males 

Follow the same procedure in exchanging 

the replacement males as for removal of the 

processing replacement males with the 

Locator ® core tool and insertion with the 

seating tool (middle piece). 

7.5 Restoring or relining of the denture 

base 

Chairside: 

Remove all colored replacement males from 

the retention housings in the denture as 

described in "7.4 Exchange of the replacement 

males" and replace them with the black 

processing replacement males. 

The black processing replacement male will 

ensure secure fixation of the denture while 

taking the impression. Do not apply any 

impression material in or around the 

Locator ® . 

While taking a relining impression, make sure 

the denture is correctly seated on the 

Locator ® abutments. 

Leave the black processing replacement 

males in the retention housings after removal 

of the relined denture base.


Selection of analogs as described in the 

diagram "In the dental lab: Selection of 

matching analogs" on page 7. 

After the impression is taken, place the 

analogs (Ø 4.0 mm or Ø 5.0 mm) into the 

retention housings and fabricate the relining 

model. 

It is advisable to use a new male processing 

package. Alternatively, carefully 

remove the previous retention housing 

from the denture and re-use it. 

Before relining the denture, place the white 

block-out spacer over the functional areas of 

the Locator ® analogs to prevent the acrylic 

from penetrating into the retention housings.
