About

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.

Full 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.

18 participants in 3 patient groups

Conventional Ridge-Splitting Group

Sham Comparator group

Description:

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.

Treatment:

Procedure: Modified Ridge-Splitting

Modified 3-Staged Ridge-Splitting Group

Active Comparator group

Description:

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.

Treatment:

Procedure: Modified Ridge-Splitting

Modified 2-Staged Ridge-Splitting Group

Experimental group

Description:

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.

Treatment:

Procedure: Modified Ridge-Splitting
