Summary
HTR polymer implants provide effective onlay facial augmentation for malar, paranasal, and chin regions. This porous material shows comparable results to other alloplastic options with minimal bone resorption.
Area of Science:
- Plastic Surgery
- Biomaterials Science
- Oral and Maxillofacial Surgery
Background:
- Facial skeletal augmentation is a common procedure.
- Alloplastic materials are frequently used for onlay augmentation.
- HTR (High-Temperature Resistant) polymer is a porous biomaterial for reconstructive surgery.
Purpose of the Study:
- To evaluate the clinical outcomes and safety of HTR polymer implants for onlay facial augmentation.
- To assess the efficacy of HTR implants in the malar, paranasal, and chin regions.
- To investigate potential complications and bone response to HTR implants.
Main Methods:
- Forty-three patients received 61 HTR polymer preformed implants for facial augmentation (malar, paranasal, chin).
- Implants were placed intraorally and fixed with titanium screws.
- Follow-up ranged from two to five years, including clinical assessment and radiographs.
Main Results:
- One implant was removed due to infection; two were removed due to pain and erythema in patients with connective tissue disease.
- One peri-implant infection was successfully treated without implant removal.
- Postoperative radiographs showed no bone resorption under chin implants after one year.
Conclusions:
- HTR polymer implants are a viable option for onlay facial skeletal augmentation.
- The material demonstrates clinical results comparable to other alloplastic materials.
- Complication rates are low, with infection and pain being the primary concerns, particularly in patients with underlying systemic conditions.
