This study introduces an improved anterior maxillary osteotomy technique for treating maxillary protrusion. The modified method offers better surgical visualization and efficiency without increasing complications.

Area of Science:

Oral and Maxillofacial Surgery
Orthognathic Surgery

Background:

Anterior maxillary osteotomy is a standard procedure for correcting maxillary protrusion.
Previous modifications aimed to mitigate surgical complications.
Continuous refinement of surgical techniques is essential in orthognathic surgery.

Purpose of the Study:

To present an improved anterior maxillary osteotomy surgical method.
To evaluate the efficacy and safety of the modified technique compared to the general approach.

Main Methods:

A prospective study comparing an improved anterior maxillary osteotomy with a general technique.
Patients were divided into two groups: improved and general.
Postoperative evaluation included occlusion, tooth vitality, and complications during regular follow-ups.

Main Results:

No significant differences were observed in operative time, blood loss, or complications between the groups.
The improved procedure provided enhanced visualization of the anterior maxillary bone.
Simplified osteotomy lines facilitated maxilla movement and reduced bone cutting time.

Conclusions:

The modified anterior maxillary osteotomy technique is clinically effective for improving dentofacial deformities.
The procedure offers surgical convenience and improved visualization.
This technique meets clinical demands for treating maxillary protrusion effectively.
