Summary
Zygomatic hexagonal implants offer a stable solution for severe maxillary resorption, ensuring proper function and form restoration. This protocol effectively distributes forces and prevents complications in patients requiring advanced dental prosthetics.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Biomaterials Science
Background:
- Severe maxillary resorption presents biomechanical challenges for dental prosthetics.
- Zygomatic implants offer an alternative anchorage point for stabilizing prostheses.
- Restoring function and form in young patients (≥30 years) with severe bone loss is a clinical goal.
Purpose of the Study:
- To describe the protocol for using zygomatic hexagonal implants.
- To evaluate the efficacy of this protocol in patients with severe maxillary bone resorption.
Main Methods:
- A cohort of ten patients with severe maxillary resorption underwent treatment with a hexagonal implant system.
- Clinical evaluations, conventional radiographs, and CT scans were used for assessment over a minimum of 24 months.
- Six implants were placed per patient based on prosthetic planning, followed by immediate provisional prosthesis and subsequent definitive prosthesis fabrication.
Main Results:
- The protocol demonstrated balanced force distribution and load concentration with passive metal bar adjustment.
- Skeletal relationships were corrected, and no implant fatigue or complications were observed during the 24-month follow-up.
- All ten patients completed the study without dropouts.
Conclusions:
- The zygomatic hexagonal implant protocol ensures barrier function, biomechanical stability, and optimal load distribution.
- It effectively prevents bone/implant interface fatigue and reduces anterior masticatory load.
- This approach corrects skeletal class III malocclusion common in severe maxillary resorption cases.
