Summary
A novel vector guidance oral prosthesis aids maxillary distraction osteogenesis (DO) by simplifying distractor placement without requiring model surgery. This innovation offers a new solution for complex cases in cleft treatment.
Area of Science:
- Craniofacial surgery
- Orthodontics
- Biomedical engineering
Background:
- Traditional vector guidance for maxillary distraction osteogenesis (DO) relies on splints that require pre-operative model surgery.
- Fabrication of conventional vector guidance splints is not feasible when dental occlusion is not decompensated for model surgery.
Purpose of the Study:
- To introduce a novel vector guidance oral prosthesis for internal distractor placement in maxillary DO.
- To provide a method for vector determination and distractor guidance when model surgery is not possible.
Main Methods:
- A new prototype, the vector guidance oral prosthesis, was fabricated.
- The mandibular occlusal plane was utilized as an anatomical reference for prosthesis design.
- The prosthesis guides distractor placement and vector determination during maxillary DO.
Main Results:
- The vector guidance oral prosthesis enables maxillary DO without the necessity of model surgery.
- This method facilitates accurate distractor placement and vector determination.
Conclusions:
- The vector guidance oral prosthesis is an effective alternative for guiding maxillary DO.
- This innovation simplifies the procedure, particularly in cases where model surgery is contraindicated or not feasible.

01:26Bone Markings
Bones have various surface features that help form joints and attach to other soft tissues. Depending on the function, bone markings are categorized into articulating projections, processes for attachment, depressions, and openings.
Articulating Projections
Articulating projections are found where two bones meet to form a joint. These structures are usually found at the ends of bones. The largest articulation is a rounded projection called the head, supported by a narrow neck at the ends of...

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...
