Summary
This study presents a one-step oral rehabilitation using Le Fort I osteotomy and computer-guided implant placement for severe jaw deformities. This innovative approach simultaneously corrects malocclusion and atrophic jaws, improving aesthetics and function.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Computer-Assisted Surgery
Background:
- Osseointegrated implants are crucial for oral rehabilitation but challenging in atrophic jaws.
- Orthognathic surgery corrects skeletal malocclusions and can be adapted for edentulous patients with jaw discrepancies.
- Computer-assisted surgery enhances implant placement accuracy through digital analysis of bone structures.
Purpose of the Study:
- To describe a one-step oral rehabilitation procedure for a posttraumatic deformity.
- To evaluate the combined use of Le Fort I osteotomy and computer-guided implant placement.
- To address challenges in reconstructing aesthetics and functionality in patients with atrophic jaws.
Main Methods:
- Treatment planning utilized computer-assisted surgery software (NobelGuide).
- Ten implants were placed (6 maxillary, 4 mandibular) using computer guidance.
- A Le Fort I osteotomy was performed simultaneously to correct maxillary deficiency without bone grafting.
Main Results:
- The procedure successfully corrected the patient's posttraumatic jaw deformity and enabled implant placement.
- Simultaneous Le Fort I osteotomy and computer-guided implant placement were achieved in a single stage.
- This approach facilitated oral rehabilitation in a patient with severe maxillary deficiency and atrophic jaws.
Conclusions:
- One-step oral rehabilitation with Le Fort I osteotomy and computer-guided implant placement is feasible in selected patients.
- This technique offers advantages over traditional preprosthetic procedures by addressing malocclusion, jaw atrophy, and aesthetics concurrently.
- Computer-assisted surgery improves implant accuracy and avoids bone grafting morbidity, presenting a viable solution for complex oral rehabilitation cases.
