A semi-precision cast splint for fixation following segmental osteotomies

Area of Science:

• Oral and Maxillofacial Surgery
• Orthognathic Surgery
• Surgical Fixation Techniques

Background:

• Intra-oral segmental osteotomies are complex procedures requiring stable fixation.
• Current fixation methods may present challenges in achieving optimal immobilisation.
• Minimally invasive fixation strategies are continually being explored.

Purpose of the Study:

• To present a new method for fixation after intra-oral segmental osteotomies.
• To describe the components and application of the proposed fixation device.
• To discuss the benefits of this specific immobilisation technique.

Main Methods:

• A three-part cast splint was designed for intra-oral application.
• A semi-precision horizontal pin attachment was incorporated to connect splint components.
• The method focuses on achieving rigid immobilisation of osteotomy segments.

Main Results:

• The described method provides stable fixation for intra-oral segmental osteotomies.
• The three-part cast splint with pin attachment ensures effective immobilisation.
• The technique facilitates predictable healing and functional recovery.

Conclusions:

• The presented fixation method offers a viable and advantageous approach for intra-oral segmental osteotomies.
• This technique simplifies immobilisation, potentially improving patient outcomes.
• Further studies may explore long-term efficacy and patient-reported benefits.
