Overcoming the Limitations of Conventional Orthognathic Surgery: A Novel Approach Using Implate

Area of Science:

• Orthognathic Surgery
• Craniofacial Surgery
• Dental Implants

Background:

• Traditional orthognathic surgery faces limitations in correcting severe mandibular retrusion and transverse deficiency simultaneously.
• Unsatisfactory functional and aesthetic outcomes can result from current techniques for Class II malocclusion.

Purpose of the Study:

• To evaluate the efficacy of a novel surgical plate, Implate, in bimaxillary osteotomy for complex Class II malocclusions.
• To assess the ability of Implate to simultaneously address mandibular retrusion and width deficiency while minimizing complications.

Main Methods:

• Seven male patients with Class II malocclusion and severe mandibular retrusion underwent bimaxillary osteotomy with mandibular advancement using the Implate system.
• Pre-surgical planning involved CBCT, 3D modeling, and surgical simulation. Postoperative assessments included clinical exams and imaging (CT, OPT).

Main Results:

• The Implate system facilitated precise osteotomy and stabilization, minimizing bony steps and improving facial profile.
• Minimally invasive procedures with careful tissue management led to stable outcomes without complications.
• At 6 months, OPT analysis showed significant increases in mandibular width (18.1 mm) and ramus height (approx. 6 mm).

Conclusions:

• Implate offers a significant improvement for complex Class II malocclusions, effectively correcting retrusion and width.
• This innovative approach combines advanced surgical techniques with 3D-printed implants for superior functional and aesthetic results.
• Further prospective studies are needed to validate Implate's efficacy and reproducibility in broader clinical applications.
