Summary
Sutural expansion osteogenesis successfully expanded goat zygomatic bones three-dimensionally using a novel external appliance. This minimally invasive technique demonstrated stable bone regeneration, offering a feasible method for zygomatic augmentation.
Area of Science:
- Craniofacial surgery
- Orthodontics
- Regenerative medicine
Background:
- Zygomatic bone deformities require effective reconstructive methods.
- Sutural expansion osteogenesis offers a potential approach for bone regeneration and augmentation.
Purpose of the Study:
- To evaluate the efficacy of a three-dimensional external expansion appliance for zygomatic bone lengthening in goats.
- To assess the stability and credibility of bone regeneration following sutural expansion osteogenesis.
Main Methods:
- A 3 cm incision was made in the infraorbital zygomatic bone of eight goats.
- A three-dimensional external expansion appliance was applied and activated at 0.9 mm/day for 10 days.
- Radiographic, clinical, and histological analyses were performed to evaluate bone regeneration.
Main Results:
- The zygomatic bones were expanded anterosuperolaterally and inferolaterally by an average of 9 mm.
- New bone formation was observed in the distracted sutures.
- The expansion appliance proved simple to operate with adjustable directional control.
Conclusions:
- Sutural expansion osteogenesis is a feasible and effective method for rapid, three-dimensional zygomatic bone expansion.
- The technique yielded stable and credible results, indicating its potential for clinical application.
- The external expansion appliance is user-friendly and adaptable for precise bone manipulation.
