[Transjugal osteosynthesis by compression miniscrew in sagittal ramus osteotomy]

Area of Science:

• Oral and Maxillofacial Surgery
• Orthognathic Surgery
• Biomaterials in Medicine

Background:

• The Obwegeser-Dalpont technique is a standard for sagittal osteotomy of the ascending rami.
• Direct compression mini-screws offer potential advantages in osteosynthesis.
• Evaluating novel fixation materials is crucial for surgical outcomes.

Observation:

• The study utilizes a direct compression mini-screw, adapted from the Michelet-Champy design.
• The transjugal approach is employed for the sagittal osteotomy.
• Two clinical cases illustrate the application of this technique and material.

Findings:

• The Michelet-Champy derived mini-screw provides rigidity, solidity, and miniaturization for osteosynthesis.
• Advantages and disadvantages of this mini-screw material are compared to existing methods.
• The technique was successfully applied in two illustrative clinical cases.

Implications:

• This technique and material may offer a viable alternative for sagittal osteotomies.
• Further research can explore long-term outcomes and broader applications.
• The findings contribute to the field of surgical fixation in orthognathic procedures.
