简要总结
This study aims to compare two different prosthetic systems used in mandibular full-arch implant-supported fixed prostheses (All-on-4). The study evaluates patient satisfaction and prosthetic complications associated with the OT-Bridge system versus multiunit abutments.
A total of 20 patients will be included and divided into two equal groups. All patients will receive implant-supported screw-retained fixed prostheses.
Clinical and prosthetic outcomes will be assessed at baseline (T0), 6 months (T6), and 12 months (T12), including evaluation of patient satisfaction and any prosthetic complications.
The findings of this study may help improve the selection of prosthetic systems to enhance clinical outcomes and patient quality of life.

结局指标
主要结局
Patient Satisfaction
时间窗: Baseline, 6 months, 12 months
Patient satisfaction will be assessed using a structured questionnaire for patients receiving mandibular All-on-4 implant-supported fixed prostheses. Satisfaction will be evaluated at baseline (T0), 6 months (T6), and 12 months (T12) after prosthesis delivery, comparing OT-Bridge system and multiunit abutments.
Prosthetic Complications
时间窗: Baseline, 6 months, 12 months
Prosthetic complications will be recorded for both groups, including screw loosening, prosthesis fracture, loss of retention, and need for maintenance or adjustment. Evaluations will be performed at T0, T6, and T12 months in mandibular All-on-4 implant-supported prostheses.
