Overdenture Attachments 

Locator^® Overdenture Attachment

The Locator attachment makes it easy for your patient to seat his or her own denture in the right place every time. It features a very low profile and is an extremely durable product. When used with the Spline implant, the height of the Locator attachment is as low as 3.5mm. The unique design retains on the inside and outside of the abutment resulting in a strong, stable design and less wear on the nylon liners. The durability of the Locator attachment also means fewer recall visits for your patients. 

A variety of abutment heights, angulation correction, and levels of retention are available to help the clinician or laboratory technician create the optimum overdenture restoration for each case.

Overdenture Using O-Ring 

O-ring attachments are used for retaining over dentures and partial dentures when resilience and facilitated oral hygiene is desired. 

The o-ring abutment is fabricated from titanium alloy and available in variable cuff heights that incorporates a coronal spherical geometry which snaps into a rubber o-ring in the denture or partial denture acrylic base. 

The o-rings are not intended for use if there is more than 10 degrees convergence or divergence between implants. The spacing between implants (center to center) must be greater than 6.5 apart. To find out more about overdenture using o-ring, use the step by step guide provided in PDF format. 

Parts involved in procedure: Spline prosthetics are available in three diameters. Please check our catalog for details and part numbers.
