Accuracy of Computer Guided Versus Conventional Ridge Splitting of Horizontal Deficient in Maxillary Anterior Alveolar Ridge

Accuracy of Computer Guided Versus Conventional Ridge Splitting of Horizontal Deficient in Maxillary Anterior Alveolar Ridge (Randomized Clinical Trial)

In patient with horizontal deficiency in alveolar ridge of the anterior maxilla, Dose computer Guided stent enhance the accuracy and clinical outcome vs conventional ridge splitting surgery????

PICO P- Horizontal deficient alveolar ridge in Anterior Maxillary Region I- Computer guided surgical cutting guide C- Conventional alveolar ridge splitting O- Clinical outcome and radiographic outcomes Primary outcome: Accuracy In computer Guided: CBCT will performed pre-operative and post-operative for measure the difference of degree in superimposition after ridge splitting.

In conventional method: Ridge mapping will applied in preoperative clinical evaluation, and measure in post-operative, the difference in splitting will calculate in millimeter (mm) Secondary outcome: Thickness of buccal cortical plate In both technique CBCT will performed and measuring the Both Buccal and palatal cortical bone in millimeter(mm)
