Summary

The four-splint technique improved centric condyle positioning in bimaxillary osteotomies. This method led to significant functional improvements for patients with preoperative disorders.

Area of Science:

  • Oral and Maxillofacial Surgery
  • Orthognathic Surgery

Background:

  • Bimaxillary osteotomies are complex procedures requiring precise condyle positioning.
  • Traditional methods often lacked reproducibility and could lead to complications.
  • The four-splint technique was introduced to address these limitations.

Purpose of the Study:

  • To evaluate the impact of the four-splint technique on centric condyle positioning during bimaxillary osteotomies.
  • To assess the functional outcomes in patients undergoing this procedure.

Main Methods:

  • A retrospective study of 622 patients undergoing bimaxillary osteotomy from 1981 to 2002.
  • Comparison between patients operated with and without the four-splint technique (continuous centric condyle positioning).
  • Analysis of preoperative functional disorders and postoperative outcomes.

Main Results:

  • The four-splint technique enabled reproducible centric condyle positioning.
  • Patients with preoperative functional disorders showed statistically significant improvement with continuous centric condyle positioning (p<0.05).
  • The technique avoided complications associated with mandibular osteotomy steps.

Conclusions:

  • Continuous centric condyle positioning using the four-splint technique is indicated in bimaxillary osteotomies.
  • The technique offers improved functional outcomes, particularly for patients with preoperative disorders.
  • This method enhances surgical reproducibility and patient results.
