Summary
Customized alloplastic implants effectively enhance facial aesthetics in orthognathic surgery patients with volume deficiencies. This case report shows a safe and stable 1-year outcome for a patient receiving a custom mandibular implant alongside orthognathic procedures.
Area of Science:
- Oral and Maxillofacial Surgery
- Plastic Surgery
- Biomaterials Engineering
Background:
- Orthognathic surgery corrects skeletal malocclusions, with facial aesthetics a key factor in patient acceptance.
- Conventional techniques may not fully address midface and lower facial contouring needs.
- Alloplastic augmentation can be an adjunctive approach for specific aesthetic demands.
Purpose of the Study:
- To describe a case of orthognathic surgery combined with a custom-made mandibular implant for midface and lower facial deficiency.
- To evaluate the safety and efficacy of custom alloplastic implants as an adjunct to orthognathic procedures.
Main Methods:
- A 58-year-old female with mandibular hypoplasia and Class II malocclusion underwent Le Fort I osteotomy and received a custom polymethyl methacrylate (PMMA) mandibular implant.
- The procedure was performed via an intraoral approach under general anesthesia.
- Postoperative care included laser therapy and physiotherapy.
Main Results:
- Successful implant placement with no intraoperative complications.
- Excellent healing at 1-year follow-up, with no infection or implant-related issues.
- Significant improvement in facial balance and harmony was achieved.
Conclusions:
- Customized alloplastic implants are a safe and effective adjunct for refining aesthetic outcomes in orthognathic surgery, particularly for volume deficiencies.
- These implants offer predictable aesthetic enhancement and long-term stability.
- Literature supports their biocompatibility and high patient satisfaction when used with skeletal procedures.
