Prosthetic rehabilitation of a hemimaxillectomy patient using a zygomatic - Corticobasal® implant- supported reconstructive prosthesis: A case report

Abstract

Introduction

Rehabilitation of patients with hemimaxillectomy presents a challenge. This case report describes the successful use of zygomatic Corticobasal® implant- supported reconstructed prosthesis.

Clinical case presentation

A 20-year-old female patient presented to the clinic following hemimaxillectomy with soft tissue approximation one year ago. The patient was very depressed and reported high aesthetic concern and masticatory inefficiency and required a fixed prosthesis. A multidisciplinary team was formed. A panorama and cone beam CT were acquired. The treatment plan included the construction of an immediately loaded, fixed implant-supported reconstructive prosthesis using 6 Corticobasal® implant (BCS® and ZDI® implant designs, Dr. Ihde Dental AG, Switzerland) and a follow up program. After 3 years in function, the patient presented with 100 % implant survival rate, no complaints, and reported great improvement in esthetics, speech, mastication, and quality of life.

Discussion

The use of zygomatic Corticobasal® implants in this case provides the significant advantages of improving the prosthesis support and the utilization of the strongest zygomatic bone for implant anchorage. Moreover, the use of a metal framework for implant splinting and the monoblock design of the implant reduce the risk of implant/prosthesis overloading, and eliminate the biomechanical complication. Furthermore, the provided fixed prosthesis matched the patient's desire and significantly optimized the patient satisfaction and quality of life.

Conclusion

Within the limitation of the study, Corticobasal® implants can be used for rehabilitating hemimaxillectomy patients with optimum peri-implant soft tissue results, reducing risk of infection, achieving high survival rate and significantly improving the patient's aesthetic, functional, and satisfaction.
