The LOCATOR® Implant Abutment System is arguably the World’s most popular implant attachment system. Specifically designed for full-arch or partial overdentures, the LOCATOR® Abutment system pivots and self-aligns to assure proper insertion, removal, and retention during function.
- Self-Aligning Attachments
- Simple patient insertion/removal of prosthesis
- Unique patented pivoting technology
- Compensates for path of insertion up to 40° of divergence between implants
During seating, the LOCATOR® nylon male pivots inside the denture cap, centering the nylon male on the female abutment before engagement. These two actions in concert allow the LOCATOR® to self-align, enabling patients to easily seat their overdenture without the need for accurate alignment and without causing damage to the attachment components.
The LOCATOR® system offers standard and extended range retention inserts which are designed for maximum versatility, retention and angulation to suit each patient’s needs.
LOCATOR® – Self-Aligning Design
The LOCATORs pivoting action and self-aligning design allow the attachments to seat effortlessly
The rounded surface of the LOCATOR® attachment allows the male to center on the attachment before engagement so it can easily locate its proper position while the LOCATOR® male pivots inside the denture cap
Once seated, the LOCATORs dual retention feature provides a firm connection both inside and outside of the attachment, delivering twice the amount of retention surface area compared to other attachments
Also once seated the LOCATOR® male remains in static contact with the attachment while the denture cap, which is processed into the overdenture, has a full range of rotational movement over the male for a genuine resilient engagement of the prosthesis without any resulting loss of retention
LOCATOR® Implant Abutments
Various height options available, LOCATOR® implant abutments are an excellent option where occlusal space is limited. Multiple levels of retention inserts are available combined with the patient easy self-aligning insertion feature provides for easy adoption for the patient.
LOCATOR® Root & Bar Attachments
LOCATOR® Standard Range Male Retention Inserts
- Allows for insertion of the overdenture onto the dental implant abutment with up to 20° of divergence between both dental implants
- Available in 1.5, 3.0, 5.0 or 8.0 lbs retention force
- Retention force can be evaluated chairside depending on patient preference for level of ease-of-insertion and removal
LOCATOR® Extended Range Male Retention Inserts
LOCATOR® Processing Packages, Inserts & Housings
LOCATOR® Processing packages come in a variety of options. Replacement components can be purchased individually or in larger quantity insert packs.
LOCATOR® Impression Copings, Analogs & Tools
LOCATORs Impression Copings, Analogs & Tools are made of high quality carbide something or another and work with all major dental implant manufacturers.
LOCATOR® Dimensional Specifications
LOCATOR® implant abutments should be ordered to the exact height of the gingival measurement.
The LOCATOR® Implant abutment has a built in additional 1.5mm of height. This 1.5mm allows the male attachment to fully seat on to the the abutment.
Please do not add 1.5mm to your measurements.
Troubleshooting LOCATOR® Attachments
Q: Why are the Retention Inserts pulling out the housing?
A: The path of insertion is likely too divergent for the standard inserts. Consider the extended range males (red, orange, green) which will accommodate a divergent implant between 10 and 20 degrees (40 degrees between implants).
Q: Why is there no retention with this NEW prosthesis?
A1: Make sure you can see the line of demarcation (undercut between the retentive area of the abutment and cuff height portion) is above the gingiva, allowing the housing and insert to engage with the Abutment. LOCATOR® implant abutments should be ordered to the exact height of the gingival measurement. The LOCATOR® implant abutment has a built in additional 1.5mm of height. This allows the male attachment to full seat on the abutment. Please do not add 1.5mm to your measurement.
A2: Try a housing or impression coping loaded with any nylon insert on the abutment. With finger pressure, is there retention? Is the housing making contact with the gingiva?
A3: If there is retention with the impression coping/housing test, it is a high spot. Use indicating paste to check for acrylic high spots or alignment of the attachment.
A4: If the position of the housing is out of alignment with the abutment, remove the nylon male, take a hot soldering tip and transfer heat into the housing (softening up the retaining acrylic), and pull the housing out of the prosthesis. Place a new black male into the housing, sandblast and prime, and go forward with the normal chairside pickup procedures. Make sure to only put pressure over the attachment areas; pressure in the gingival supported areas will cause compression of gingiva and therefore a misalignment of attachment and abutment.
Q: Why is there no retention with this OLD/EXISTING prosthesis?
A1: Is the inside of the LOCATOR® abutment clean of debris?
A2: Do you see any wear facet/gold TiN coming off of the abutment and the silver undercoating showing up? This is likely from worn/rough inserts making vertical striations into the abutment when the patient is biting it into place. To check retention, use an impression coping to see if there is retention on the abutment. If no retention, you need a new abutment.
A2: Finally, if there is retention, check for a reline.
- Take a 0.5mm of thin/base plate wax and wrap it around the saddle area of the process.
- Replace the inserts with the black processing inserts.
- Seat the prosthesis back in the patient’s mouth and have them come into occlusion.
- Remove the prosthesis and check for contact marks.
- If there is no contact, that means there has been a loss of more than 0.5mm of supportive bone/tissue. Reline to compensate for what has been lost.
