Correction of open bite by maxillary osteotomy. A comparison between bone plate and wire fixation

Area of Science:

• Oral and Maxillofacial Surgery
• Orthodontics
• Craniofacial Surgery

Background:

• Open bite deformity presents a significant challenge in maxillofacial surgery.
• Standardized surgical correction methods are crucial for predictable outcomes.
• Comparing fixation techniques is essential for optimizing patient care.

Purpose of the Study:

• To compare the clinical and cephalometric stability of two maxillary fixation methods after open bite correction.
• To evaluate relapse tendencies between direct wire and plate fixation techniques.
• To assess patient comfort and clinical advantages associated with each fixation method.

Main Methods:

• A prospective, standardized clinical and cephalometric study involving 19 patients with open bite deformity.
• Two fixation groups: direct wires with suspension wires (n=9) and miniplate fixation (n=10).
• Follow-up assessments at 2, 6, and 18 months post-surgery.

Main Results:

• Both direct wire and plate fixation groups demonstrated short-term (2, 6 months) and medium-term (18 months) clinical and cephalometric stability.
• No statistically significant difference in relapse tendency was observed between the two fixation groups.
• Plate fixation was associated with greater clinical advantages and improved patient comfort.

Conclusions:

• Both fixation methods provide stable results for surgical correction of open bite deformities.
• Miniplate fixation is recommended for maxillary surgical procedures due to enhanced patient comfort and clinical benefits.
• Further research may explore long-term outcomes and cost-effectiveness of plate fixation.
