Overdenture restoration: Attachment-retained solution 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. Gingiva height Disclaimer: Some products may not be regulatory cleared/released for sale in all markets.

Abutment connection Hand tighten the Locator® Abutment to the implant using the Latch Type Torque Wrench Driver connected to the Manual Torque Wrench Adapter Prosthetic. Tighten the Abutment to 35 Ncm using the Manual Torque Wrench Prosthetic. 2. 3. 3. Place Block-Out Spacer and Denture Caps Place the white block-out spacer ring on each abutment. The spacer ring is used to block out the area surrounding the abutment. Place the denture caps with the black processing males onto the Locator® Abutment.

Hollow out denture base Use an appropriate method to mark the locations of the Locator® Abutments on the existing denture. Hollow out the existing denture base in the areas of the Locator® Denture Caps. 5. Anchor denture caps Fill the receptor sites with prosthetic resin (Light cure or self-curing resin). Apply suitable bonding agent onto Locator® Denture Caps. Lingual connecting holes may be used to anchor the denture caps in the denture. Seat denture and confirm proper occlusion. Cure resin in light occlusion without compression of the soft tissue. Once the resin has cured remove the denture from the mouth and discard the white block-out spacers. Ensure the denture caps are fully embedded with resin. Remove any excess resin and polish the denture.
