Digitally Fabricated Inter-occlusal Wafer Versus Wafer-less Distal Segment Repositioning for Bilateral Sagittal Split Osteotomy in Skeletal Mandibular Deformities (Randomized Controlled Trial)

Status: Recruiting
Location: See location...
Intervention Type: Procedure
Study Type: Interventional
Study Phase: Not Applicable

Research studies continues to attempt testing modifications to refine the treatment protocols through computer assisted design or computer-generated surgical Wafer splints, have greatly revolutionized the incorporation of digital imaging and 3D design in Orthognathic surgery. Integrating computer guided technology in orthognathic surgery aims to to simplify workup and reduce surgical errors, eliminate occlusal discrepancy, increase the realignment accuracy of the distal segments according to the preoperative plan. Implementing a waferless technique raised the question of efficiency versus the use of occlusal wafers and whether it has a significant measurable effect on the surgical outcome and objectives. Rationale for conducting this study is to assess the difference between the effect of computer guided waferless technique and computer guided technique with occlusal wafer on accuracy of postoperative occlusion and condylar position. .
