Summary
Maxillary rehabilitation using custom subperiosteal implants offers a predictable solution for severe bone defects. This additive manufactured approach improved patient quality of life after previous implant failures.
Area of Science:
- Oral and Maxillofacial Surgery
- Biomaterials Engineering
- Digital Dentistry
Background:
- Maxillary rehabilitation presents persistent challenges in Oral and Maxillofacial Surgery, even with advanced techniques.
- Previous prosthetic rehabilitation attempts, including zygomatic implants, failed to yield satisfactory outcomes for this patient.
- Sequelae from prior interventions necessitated implant removal and exploration of alternative solutions.
Observation:
- A patient with a history of multiple failed maxillary reconstructions was treated.
- Bilateral zygomatic implants were placed but ultimately failed, requiring removal.
- A custom subperiosteal implant, fabricated using additive manufacturing, was then utilized for rehabilitation.
Findings:
- The custom subperiosteal implant, designed with virtual planning and simulation, successfully rehabilitated the severely atrophic maxilla.
- The patient has experienced over a year of successful rehabilitation with no complaints.
- Significant improvement in the patient's quality of life was observed.
Implications:
- Custom subperiosteal implants manufactured via additive manufacturing represent a viable and predictable alternative for complex maxillary reconstructions.
- This technology enables precise rehabilitation of extensive bone defects, addressing limitations of traditional methods.
- Virtual planning and simulation enhance the predictability and success rates of these advanced prosthetic solutions.

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
01:27Fractures: Bone Repair
Treatment for a fracture is based on the type of break, the bone affected, and the patient's age.
Minor fractures with no bone displacement are treated by immobilizing the fractured bone using a cast or splint. However, in the case of fractures with displaced bones, the broken bones are repositioned before immobilization to ensure successful healing without deformation and loss of function. The realignment of fractured bone ends is performed through a process called reduction. If the procedure...
