11-Year Long-Term Success of Full Posterior Implant Rehabilitation in Both Arches

Dr. Jongyub Kim (Korea)


Case Summary 🔎

This case presents a full posterior implant rehabilitation involving both arches, maintained in stable condition for over 11 years with no significant biological or mechanical complications.


Case Presentation

1️⃣ Diagnosis

Chief Complaint (C.C)

  • The patient reports difficulty using the anterior teeth and long-term neglect of the posterior dentition.


Diagnosis

  1. Severe caries in the maxillary anterior region, affecting esthetics and function.

  2. Multiple posterior teeth are either missing or remain as root remnants in both arches, indicating long-term neglect.

  3. Generalized chronic periodontitis with associated alveolar bone loss.


Treatment Plan

  1. #14, 15, 17, 24, 25, 26, 27, 35, 36, 37, 46, 47 Extraction

  2. #14, 24, 35, 36, 37, 45, 46, 47 Implant placement

  3. #16, 17, 26, 27 Implant placement and sinus graft

  4. Maxillary anterior endodontic treatment and prosthetic

  5. Mandibular posterior supra-eruption requiring bone reduction


2️⃣ Pre-Op

  • Alveolar bone reduction was indicated due to supra-eruption in the posterior region following prolonged tooth loss.

  • Generalized severe dental caries involving anterior and posterior teeth.


3️⃣ Surgical Phase

04 July 2012

  • After #46, 47 extraction


13 July 2012

  • #45, 46 Implant placement and autogenous bone graft

  • Bone reduction was performed to correct mandibular posterior supra-eruption.
