Summary
Patient-specific titanium implants demonstrate excellent effectiveness and safety for maxillofacial reconstruction. Long-term follow-up confirmed high patient satisfaction and successful bone fusion, with minimal complications.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomaterials Engineering
- Regenerative Medicine
Background:
- Maxillofacial defects require advanced reconstructive solutions.
- Patient-specific implants offer tailored anatomical restoration.
- Titanium's biocompatibility makes it ideal for bone reconstruction.
Purpose of the Study:
- To evaluate the long-term effectiveness and safety of patient-specific titanium implants in maxillofacial reconstruction.
- To assess bone fusion, functional outcomes, and patient satisfaction after using custom titanium implants.
- To analyze complications associated with titanium implants in the maxilla, mandible, and zygoma.
Main Methods:
- Retrospective analysis of 16 patients undergoing maxillofacial reconstruction with patient-specific titanium implants.
- Implants manufactured via electron beam melting, selective laser sintering, or milling.
- Long-term follow-up (mean 36.7 months) assessing bone fusion, infection, malunion, function, satisfaction, subsidence, osteolysis, and complications.
Main Results:
- High success rate with only one implant failure requiring revision surgery out of 28 implants.
- No observed osteolysis or subsidence around implants; no adverse events reported.
- Excellent patient satisfaction (mean VAS score 9) and resolution of fixation/esthetic issues.
Conclusions:
- Patient-specific titanium implants are effective and safe for reconstructing various maxillofacial defects.
- 3D printed titanium implants provide a viable alternative to autogenous bone grafts, avoiding donor site morbidity.
- Customized titanium solutions achieve high esthetic and functional outcomes in maxillofacial surgery.
