Survival Rate of Implants and Mechanical Complications for 64 Implant-Supported Complete-Arch Prostheses in Maxillary Edentulous Patients with a Follow-up of up to 12 Years: A Cross-Sectional Analytical Study.

Purpose: To identify the technical complications associated with maxillary complete-arch implant-supported fixed prostheses (ISFPs) and to evaluate the survival rates of both dental implants and prostheses. In addition, we sought to analyze the impact that the presence of cantilevers, the type of prosthetic abutment, and the number of implants have on the occurrence of complications.

Materials And Methods: Data were obtained from standardized clinical assessments carried out in a single appointment by two calibrated professionals (F.
