28. CLINICAL FEATURES, PARACLINICAL FINDINGS, TREATMENT OUTCOMES OF PATIENTS HAVING COMPLICATIONS WITH FULL-ARCH IMPLANT-SUPPORTED FIXED PROSTHESIS CONNECTED BY THE MULTI UNIT ABUTMENT AT THE ODONTO MAXILLO FACIAL HOSPITAL OF HO CHI MINH CITY IN 2023-2024

Abstract
Introduction: Full-arch fixed prostheses supported on implants using the Multi Unit Abutment system, which offers numerous advantages, are increasingly being applied worldwide and in Vietnam. However, there is still limited research on the complications associated with this treatment method.
Research objective: The objective of this study is to describe the clinical and paraclinical characteristics of patients with complications who are wearing full-arch fixed prostheses on implants connected by the Multi Unit Abutment (MUA) system, and to evaluate the treatment outcomes of these complications.
Subjects and Methods: This study includes cases series. Patients with full-arch fixed prostheses on implants connected by the MUA system who came for examination and treatment of complications at the Dental Implant Department, Ho Chi Minh City Hospital of Odonto-Stomatology and agreed to participate in the study were classified into two groups, biological and mechanical, with minor and major levels. The clinical, paraclinical characteristics and treatment outcomes of complications were recorded.
Results: Thirty patients (mean age: 60.70±8.70) participated in the study, with 21 cases of mechanical complications (70%) and 9 cases of biological complications (30%). Most minor mechanical complications were resolved in one appointment, while major complications required more than two appointments to manage. The mPLI and mBI indexes, as well as pocket depth, significantly decreased (p<0.05) after treatment.
Conclusion: Full-arch fixed prostheses supported on implants using the MUA system can be considered a functionally reliable restoration method. However, attention must be paid to the potential mechanical complications.
