Conventional Loading of Two Implants in the Mandible and Final Restoration with a Locator-Supported RDP

Arne Boeckler, Dean Morton

An 83-year-old male patient requested treatment for his existing maxillary complete overdenture and mandibular complete denture. He reported no general medical conditions of significance that would affect his dental treatment and was taking no prescription medication. He denied suffering from oral pain and displayed no evidence of parafunctional habits or temporomandibular joint disorder. Oral and radiographic evaluation revealed two retained maxillary teeth (13 and 15) supporting prefabricated ballshaped attachments. Both teeth were mobile and associated with active periodontal disease and extensive dental caries; these were considered non-restorable and were recommended for extraction. The patient’s existing complete maxillary and mandibular prostheses were approximately 2 years old. He was very satisfied with the appearance of both prostheses. His chief complaint was related to the instability and lack of retention associated with the existing mandibular prosthesis.

  • * General SAC assessment modifiers that are also part of the ERA. To avoid redundancy they are listed in this section even if no complete ERA has been made.

  • ** Not applicable to the ERA of immediate placement cases and replaced by "Socket Integrity" listed below under "Surgical SAC Classification". For all other placement types this value is a classification determinant and listed here even if no complete ERA has been made.
