All-On-4 Implant with Hybrid Prosthesis Opposing Implant Supported Overdenture- A Case Report

Abstract

Implant-supported prosthetic solutions have revolutionized the field of dental rehabilitation, particularly for patients with extensive edentulism or failing dentition. Among these, the All-on-4 implant technique has gained popularity due to its ability to provide and aesthetic restoration with fewer implants and reduced surgical complexity. However, challenges such as insufficient bone volume or poor bone quality in the edentulous maxilla or mandible may necessitate alternative approaches to ensure long-term success and patient satisfaction. One such approach involves the integration of a hybrid prosthesis with All-on-4 implant concept opposing an implant-supported overdenture. This hybrid solution combines the stability and support of dental implants with the comfort and versatility of removable prostheses, offering a balance between fixed and removable options. Key aspects covered include the selection of appropriate candidates for this treatment modality, diagnostic imaging techniques for precise implant placement, surgical protocols for achieving optimal osseointegration and soft tissue management, prosthetic fabrication processes including material selection and occlusal considerations, postoperative care and maintenance strategies to ensure long-term success. Through a comprehensive examination of current literature, clinical case studies, and expert opinions, this case report aims to provide clinicians with valuable insights into the rationale, planning, execution, and outcomes of utilizing a hybrid prosthesis with All-on-4 implant concept opposing an implant-supported overdenture. By understanding the indications, advantages, limitations, and clinical nuances of this treatment approach, dental professionals can effectively address the diverse needs and preferences of edentulous or near-edentulous patients, ultimately improving their quality of life and oral health outcomes.
