Expert information from the ada. The clinical and radiographic examinations of edentulous patients generally occur during an assessment of the need for prostheses The most common pathological conditions detected are impacted teeth and retained roots with and without associated disease.51 other less common conditions also may be detected Bony spicules along the alveolar ridge. A patient with a fully edentulous mandible is ready to receive an implant/abutment supported overdenture The oral surgeon performs the first stage surgery to place the implant fixture (aka “post” or “body”)
After osseointegration, the surgeon performs a second stage surgery and places a prefabricated abutment before referring for completion of the prosthesis. ©2024 american dental association (ada) All rights reserved.©2024 american dental association (ada) A maxillary implant/abutment supported removable resection prosthesis for the partial edentulous maxillary arch in which a portion of the maxilla is resected and reconstructed with hard tissue. This procedure involves the use of grafts to stimulate periodontal regeneration when the disease process has led to a deformity of the bone This procedure does not include flap entry and closure, wound debridement, osseous contouring, or the placement of biologic materials or barrier membranes to aid in osseous tissue regeneration or barrier membranes
The two scenarios illustrate coding for placement of maxillary and mandibular overdentures for a fully edentulous patient This guidance also applies to placement of other types of overdentures (e.g., partial).
