Comparison between Modified Bone-splitting Technique and Distraction Osteogenesis in Horizontal Alveolar Ridge Expansion: Randomized Clinical Study.

Aim: This study aimed to compare modified ridge splitting (RS) and distraction osteogenesis (DO) for horizontal ridge expansion clinically (bone width, pain, and soft tissue healing) and radiographically (bone width).

Material And Methods: This randomized clinical trial was conducted on fourteen patients who had a partial edentulous narrow mandibular posterior alveolar ridge (not less than 4-mm width and 12-mm height). All patients were divided randomly into two equal groups: Group I was treated with a modified bone-splitting technique, and group II was treated with DO technique by the fabricated device as AlveoWider®, and without any graft material for both groups.
