Clinical Stability of Bespoke Snowman Plates for Fixation following Sagittal Split Ramus Osteotomy of the Mandible

Maxillofacial skeletal surgery often involves the use of patient-specific implants. However, errors in obtaining patient data and designing manufacturing plates guides can occur even with accurate virtual surgery. To address these errors, bespoke Snowman were designed to allow movement mandible. This study aimed compare stability four-hole miniplates that a plate for bilateral sagittal split ramus osteotomy (SSRO), present method investigate joint cavity changes, as well superimpose actual surgical images retrospective included 22 patients who met inclusion criteria underwent orthognathic at university hospital between 2015 2018. Two groups formed on basis used: control group plates. Stability was assessed by measuring condyle–fossa space superimposing three-dimensional postoperative cone-beam computed tomography (CBCT) scans. No significant differences observed preoperatively 1 year postoperatively groups. Superimposing CBCT scans revealed minimal landmark points, no variation or timepoints. The stabilizing mandible following SSRO exhibited clinical reliability similar those Additionally, novel introduced evaluate separately analyzing gap changes assessing mandibular position.
