| Abstract | ||||
| Background: Advances in computer-aided surgeries and virtual planning have increased the precision of surgically guided techniques and have improved the utilization of specific-patient implants. The purpose of this research was to present a radiographic technique for evaluating the gain of soft tissue with computer guided advancement genioplasty versus specific-patient PEEK chin implants in patients having recessed chins. Materials and methods: Patients with recessed chins who required corrective genioplasty were selected and divided arbitrarily and evenly into 2 groups. Group A underwent computer-guided advancement genioplasty. While, Group B was given a specific-patient PEEK onlay chin implant. Preoperative and 1-year postoperative CT images were superimposed, and the 3D produced soft tissue shapes were compared. Patients were provided with information on the study's purpose, as well as the potential risks and advantages associated with the surgery and treatment plan. Verbal consent was obtained from all patients to confirm their approval to participate in the present study. Results: Ten patients were included in each group. The chin advancement mean in Group A was 7.569 mm ± 0.82 having significantly higher mean than 6.20 mm ± 1.26 for Group B. The 1 year gain of soft tissue mean in Group A was 7.195 mm ± 0.67 having significantly higher mean than 4.745 mm ± 1.65 for Group B. Conclusion: Radiographic soft tissue assessment is a dependable method for evaluating changes in soft tissues. In addition, Computer guided advancement genioplasty may result in greater improvement of soft tissue than PEEK chin implants. | ||||
