What Are the Three Dimensional Soft Tissue Changes That Occur After Orthognathic Surgery for Skeletal Class II Patients? Pre-test Post-test Quasi Experimental Study

What Are the Three Dimensional Soft Tissue Changes That Occur After Orthognathic Surgery for Skeletal Class II Patients? Pre-test Post-test Quasi Experimental Study

the aim of the study is to establish reference data that could be used for the creation of more accurate three dimensional prediction of soft tissue outcome.

in this study, 15 skeletal class 2 orthognathic patients will be selected. CBCT and proface will be done preoperatively. after the surgery and 6 months later the imaging investigations will be repeated to investigate the soft tissue changes that have resulted due to the bone movement.

Inclusion Criteria:

• Patients with class II skeletal deformity
• Patients must be over 18 years of age to allow for growth cessation
• Patients must not have any systemic condition which contraindicates general anaesthesia

Exclusion Criteria:

• o patients with cleft palate

  • patients with syndromes affecting their craniofacial structure
  • patients with facial scars
  • patients with severe facial asymmetry
