Summary
This case report introduces a model surgery technique to predict transverse expansion for mandibular midline distraction osteogenesis. The method uses a 3D model and articulator to visualize arch relationships before surgery.
Area of Science:
- Dentistry
- Orthodontics
- Maxillofacial Surgery
Background:
- Mandibular transverse arch deficiency can be corrected using mandibular midline distraction osteogenesis.
- Predicting the amount of transverse expansion is crucial for successful surgical outcomes.
Observation:
- A novel model surgery technique is presented using a 3D stereolithography model and a semi-adjustable articulator.
- The technique involves sectioning the mandibular model at the midline and rotating segments laterally to simulate expansion.
Findings:
- This technique allows for visualization of the post-expansion relationship between the maxillary and mandibular arches.
- The model surgery provides predictable information on the achievable transverse expansion.
Implications:
- This predictive model surgery aids surgeons and orthodontists in planning mandibular distraction osteogenesis.
- It enhances treatment predictability and potentially improves outcomes for patients with mandibular transverse arch deficiency.
