Three-Dimensional Outcome Assessments of Surgical Correction in Cleft and Noncleft Patients with Class III Skeletal Relation: A Case-Control Study

Figure 1

(a) Reverse engineering was applied to fabricate the surgical guide. A stereolithographic model demonstrating the planned maxillary reposition was produced. The fixation miniplates serving as the guiding plate (the 2nd guiding plate) were prebent according to the plate holes marked on the model. (b) Anterior nasal spine (ANS) and infrazygomatic crest (IZC) were used as reference structures for designing the guiding plate on the presurgical virtual maxilla. (c, d) The mandibular guiding plates were also fabricated according to the final position of MMC to provide predicted amounts of the movements of the mandibular segments intraoperatively.
