Patient Outcomes of Staged Ridge-splitting Using Piezo-electric Surgery in Atrophic Posterior Mandible
- Conditions
- Alveolar Ridge Augmentation
- Interventions
- Procedure: Modified Ridge-Splitting
- Registration Number
- NCT06200077
- Lead Sponsor
- Mansoura University
- Brief Summary
This study aims to evaluate the clinical and radiographic outcomes of different staged ridge-splitting techniques for management of severely resorbed lower jaws in the posterior region. The study is designed as a clinical trial, so that three different interventions would be compared for a conclusion highlighting the relative best of them.
- Detailed Description
In the context of the care of severely resorbed lower jaws in the posterior region, the purpose of this study is to evaluate the clinical and radiographic outcomes of several stepwise ridge-splitting procedures. The study is supposed to be a clinical trial, with the purpose of comparing three distinct therapies in order to get a result that highlights which of them is the most effective in comparison to the others.

Group Intervention Description Conventional Ridge-Splitting Group Modified Ridge-Splitting Six dental implant sites were prepared in three patients initially through ridge splitting technique associated with bone grafting followed by implants insertion after 4 months later. Modified 2-Staged Ridge-Splitting Group Modified Ridge-Splitting Six dental implant sites were prepared in three patients initially through mucogingival, and bony incision followed by ridge splitting technique, bone grafting and implants insertion at the same time after 4 weeks from the bony incision. Modified 3-Staged Ridge-Splitting Group Modified Ridge-Splitting Six dental implant sites were prepared in four patients through mucogingival and bony incision initially then after 3-4 weeks ridge splitting with bone grafting were done, followed by implants insertion after 4 months later.
- Primary Outcome Measures
Name Time Method Alveolar ridge width immediately after implant placement, immediately after implant loading and six months after implant loading Radiographically via Cone-beam Computed Tomography (CBCT), the width of the alveolar bone was measured horizontally from the buccal to lingual cortex below the crest of the alveolar bone from 3 levels at 1 mm, 3 mm and 6 mm on three cross-sections by the CBCT software (OnDemand, Cybermed Inc, Korea).
- Secondary Outcome Measures
Name Time Method Implant stability immediately after implant placement, immediately after implant loading and six months after implant loading Smartpeg was installed in the dental implant fixture. From both buccal and lingual directions, an analyzer probe was located closer to the Smartpeg, and the implant stability quotient (ISQ) values were obtained from the Osstell Monitor
