Summary
Zygomatic implants offer a solution for oral dysfunction after maxillectomy. Virtual planning and navigation enhance implant placement safety for complex maxillary defects, improving patient outcomes.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Oncology
Background:
- Complete maxillectomy for neoplastic lesions causes significant oral dysfunction.
- Zygomatic implants are a viable option for supporting fixed bridges in maxillary defects post-tumor resection.
Purpose of the Study:
- To evaluate the effectiveness of zygomatic implants with immediate prosthetic loading for rehabilitating maxillary defects.
- To assess the role of virtual preoperative planning and intraoperative navigation in managing complex maxillary defects.
Main Methods:
- A clinical study involving patients with diverse maxillary defect types.
- Delayed rehabilitation using zygomatic implants and immediate prosthetic loading.
- Virtual preoperative planning and intraoperative navigation utilized in all cases.
Main Results:
- Seventeen zygomatic implants were placed in five patients.
- Four patients received immediate loading of a fixed prosthesis; one had delayed loading.
- One implant failure was reported in the study.
Conclusions:
- Virtual surgical planning and intraoperative navigation improve the safety of implant positioning in challenging anatomical areas.
- A novel bone defect classification system and tailored treatment protocols were developed for maxillary reconstruction.
