[EO-2] Full-arch implant treatment for patients with insufficient bone volume for a stable long-term prognosis
[Abstract]
Introduction
In recent years, fixed implant treatment for full arch cases has become stable due to the development of digital implant treatment and the use of zirconia materials.1) However, clear guidelines regarding the number and position of implant bodies, the design of the superstructure, etc. have not been provided. We report an attempt to stable the long-term prognosis by performing implant inclination placement, GBR bone grafting, and precise guided surgery in a case with a significant minimum bone volume.
Case Summary and Treatment Details
The patient was a 62 years old Female with a completely edentulous upper jaw, natural teeth affected by periodontal disease in the mandible, and peri-implantitis was observed on the implants in the right side molars. The amount of bone in the anterior maxilla was minimal, and no bone amount was observed in the molars up to the maxillary sinus. Precise guided surgery was performed by the shortest implant placement in the anterior region and the tilting implant placement in the molar region. After osseointegration of the implant was achieved, the morphology and occlusion of the final superstructure were explored in provisional restoration. The final superstructure was delivered with zirconia screw retaining prosthesis (Fig. 1, 2) to provide functionality and esthetics.
Progress and Discussion
Full-arch implant treatment for cases with insufficient bone volume is often limited in the number and position of implants that can be placed. Inappropriate implant placement may induce complications and pose a problem in long-term prognosis.2) In this case, we were able to create a highly accurate superstructure using guided surgery based on accurate computer simulation and a zirconia superstructure. We report the details of the surgical techniques and prosthetic treatment used to stabilize the long-term prognosis of this case. This case report will be conducted with the consent of the patient.
