ABSTRACT
AIM: This Study Was Conducted To Assess And Compare Clinically And Radiographically The Effectiveness Of Computer Guided Technique In Ridge Splitting Over The Conventional Technique. In Augmenting The Horizontal Deficient Anterior Maxilla.Methods: 10patients (32 Implants) With Severely Atrophied Anterior Maxillary Alveolar Ridges, Fiveof Them Underwent Rehabilitation Using Computer Guided Stents (study Group) And The Others Underwent Rehabilitation By Conventional Technique (control Group). Radiographic Assessment Included Measurements Of Changes In The Horizontal Dimensions On Cross Sectional Cuts Of Computed Tomography (CBCT) Using Special Software. Result: Mean Value Of Difference In Accuracy Of Conventional Group (0.54?0.29) Was Higher Than Mean Value Of Computer Guided Group (0.29?0.26) Yet The Difference Was Not Significant(p=0.189). Mean Value Of Bone Gain Of Computer Guided Group (2.81?0.58) Was Higher Than Mean Value Of Conventional Group (2.32?0.16) Yet The Difference Was Not Significant (p=0.106) Conclusion: For The Alveolar Ridge With Insufficientthickness But Adequate Height, This Computer Guided Flaplessalveolar Ridge Splitting Technique Can Be A Predictable, Less Invasive, An Atraumatic Technique And Available Treatment Option When Immediate Implant Placement Is A Prerequisite And Minimized Treatment Time Is Required.
