Brief Summary:
In patients with chin deformeties, will using a custom made titanium plate in the positioning of the genial segments give an accurate results in comparison to the preoperative planned osteotomy and move of the Genioplasty.

Condition or disease Intervention/treatment Phase
Macrogenia Microgenia Miniplate Procedure: Osseous Genioplasty Not Applicable

Study Type : Interventional  (Clinical Trial)
Estimated Enrollment : 10 participants
Allocation: N/A
Intervention Model: Single Group Assignment
Masking: None (Open Label)
Primary Purpose: Treatment
Official Title: Evaluation of The Accuracy of CAD-CAM Custom Made Titanium Miniplates In Positioning of the Genial Segment in Computer Guided Genioplasty
Estimated Study Start Date : September 2018
Estimated Primary Completion Date : September 2019
Estimated Study Completion Date : October 2019

Arm Intervention/treatment
Experimental: Patients need genioplasty Procedure: Osseous Genioplasty
Surgical Procedure that cuts the chin and reposition it in the correct place

Primary Outcome Measures :
  1. Accuracy Of the Custom Made Miniplate [ Time Frame: one year ]

    Hausdorff function analysis (Topographic Color Mapping) by superimposition of both preoperative and postoperative computed tomography 3D scans and obtaining numerical values.

    Data management and analysis will be performed using Statistical Package for Social Sciences (SPSS) vs.21. Numerical data will be summarized using means and standard deviations or median and range as appropriate. Correlation analysis between Accuracy of computer assisted custom made plate and preoperative 3D virtual planning will be done using Pearson or Sperman rho as appropriate. Paired t test will be done and equivelance limit will be tested. All p- values are two sided. P- Values <0.05 will be considered significant.

Secondary Outcome Measures :
  1. Patient Satisfaction (Esthetics) [ Time Frame: one year ]
    Questionnaire with numerical scale ranging from minimal score ( number 1) to maximum score (number 10) in ascending manner where the minimal score indicated unpleasant or unsatisfactory result ( doesn't meet the patient expectation) and maximum score indicated satisfactory and pleasant result (fully meets patient satisfaction).
