Digitally guided corticotomy using a customized surgical template (Suya corticotomy utility template): A technique...

Area of Science:

• Dental Surgery
• Orthodontics
• Digital Dentistry

Background:

• Surgically facilitated orthodontic therapy relies on precise corticotomy line control.
• Traditional freehand Suya method poses risks of root damage and inconsistency.
• A digitally guided protocol offers enhanced safety and predictability.

Observation:

• A digital workflow integrated cone-beam computed tomography (CBCT) and intraoral scanning (IOS) for 3D maxilla modeling.
• Vertical and apical osteotomy lines were virtually planned between roots.
• A customized 3D-printed surgical template (Suya corticotomy utility template) guided piezoelectric and chisel applications.

Findings:

• Digitally guided corticotomy was performed with high accuracy and reproducibility in a patient.
• Piezoelectric incisions and chisel applications precisely followed preplanned paths.
• Postoperative CBCT confirmed safe osteotomy positioning without root contact or damage.

Implications:

• The digitally guided Suya method provides a reproducible and biologically sound approach for root-sensitive corticotomy.
• 3D-printed guides enhance safety, accuracy, and standardization in corticotomy procedures.
• This workflow minimizes surgical variability and root damage risk in adult patients with dense bone.
