Clinical Case Report

Immediate Loading of Four Implants in the Mandible and Final Restoration with a Full-Arch Metal Framework FDP

Pedro Tortamano, Luiz Otávio Alves Camargo

A fully edentulous 65-year-old woman was referred to our clinic for esthetic and functional dental rehabilitation. The patient presented with inadequate complete maxillary and mandibular prostheses, insufficient vertical dimension, and extensive tooth wear. The clinical examination and anamnesis showed no local or systemic contraindications, no signs or symptoms of bruxism, and an absence of smoking habits. The treatment proposed was implant placement in the mandibular interforaminal area and immediate loading with a fixed definitive prosthesis. A removable mucosa-supported complete prosthesis was indicated for the upper jaw, since its bone structure offered satisfactory retention and the financial condition of the patient disfavored a full-mouth implant-supported rehabilitation.

  • * 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.
