Computer-Aided Design/Manufacturing for Le Fort I Osteotomy and 3D-customized Titanium Plate in Orthognathic Surgery

Assessment Of Computer-Aided Design/Manufacturing for Le Fort I Osteotomy and 3D-customized Titanium Plate in Orthognathic Surgery (Clinical Trial)

Background: In orthognathic surgery, virtual planning is gradually taking over in clinical practice. To start with, virtual surgery planning (VSP) is believed to be less time-consuming and less expensive than conventional surgery planning (CSP). Moreover, the improved visualization of craniofacial deformities, such as occlusal canting and asymmetries, is a further advantage. Aim: To assess the result of Le Fort I osteotomy using CAD/CAM and 3Dcustomized titanium plate with virtual planning in orthognathic surgery. Materials and Methods: 8 patients with vertical maxillary excess will be included in the study. Le Fort I osteotomy using CAD CAM surgical guide and 3Dcustomized plate will be done for the study group. All patients will be followed clinically and radiographically for one month.

Inclusion Criteria:

• Patients with non-syndromic dentofacial deformity requiring isolated Le Fort I with or without bimaxillary osteotomy.
• Patients with good oral hygiene.
• Class II or III malocclusion.
• Patients who were scheduled to undergo a CT scan as a part of their diagnosis and treatment

Exclusion Criteria:

• Patients with acute infection at the surgery site.
• Patient with Systemic disorders contraindicating surgery.
• Smokers.
• Alcohol or drug abuse is prohibited.
• patients who suffered from craniofacial syndrome;
• patients who had previous orthognathic surgery;
• patients who had previous maxillary or mandibular trauma
