Cone Beam Guided Corticotomy Using Piezoelectric Surgery.

Area of Science:

• Orthodontics
• Oral and Maxillofacial Surgery
• Radiology

Background:

• Bimaxillary protrusion often requires complex orthodontic treatment.
• Conventional orthodontic treatment can be lengthy and may have limitations in skeletal and dental corrections.
• Corticotomy-facilitated orthodontics offers a potential method to enhance orthodontic outcomes.

Purpose of the Study:

• To compare skeletal and dental angular measurements between cone beam guided corticotomy-facilitated orthodontics and conventional orthodontics.
• To evaluate the difference in total treatment time between the two orthodontic approaches.

Main Methods:

• Adult patients with bimaxillary protrusion were randomly assigned to either corticotomy-facilitated orthodontics (test group) or conventional orthodontics (control group).
• The test group utilized cone beam computed tomography (CBCT) for surgical guide construction and piezoelectric corticotomy.
• Skeletal and dental angular measurements, along with treatment duration, were recorded and compared between groups.

Main Results:

• The corticotomy group showed significant improvements in specific skeletal and dental angular measurements (SN - U1°, interincisal angle) compared to the control group.
• The control group exhibited a significant decrease in the facial angle, while the test group did not.
• The test group experienced a significantly shorter total treatment time.

Conclusions:

• Cone beam imaging aids in precise diagnosis and treatment planning for corticotomy-facilitated orthodontics.
• Guided corticotomy presents a novel, simplified surgical technique.
• Corticotomy-facilitated orthodontics demonstrates superior skeletal and dental angular correction and reduced treatment duration for bimaxillary protrusion compared to conventional methods.
