For an existing and well functioning overdenture the Locator® system can be used in a chair-side procedure.
1. Select abutment height
Select the height of the Locator® Abutment by determining the height of the gingiva at its highest point.
Choose the corresponding abutment tissue cuff height or the next closest higher size available.
The correct tissue cuff height of Locator® Abutment should create a functional attachment 1,5 mm above the surrounding gingival level and not be submerged below the tissue.
