520		3	_aIntroduction: Patient-specific customized plate become very valuable in fixation of various osteotomy including vertical ramus osteotomy in cases of mandibular prognanthism require setback. Evaluation of patient satisfaction of these technique is mandatory to determine their validity and reliability. Aim of study: is to compare the effect of customized fixation plate following intraoral vertical ramus osteotomy versus vertical ramus osteotomy fixed with MMF in perception of patient satisfaction . Methods: 20 patients were recruited in this study. They were all having skeletal class III mandibular prognanthism that was managed by mandibular setback by intra oral vertical ramus osteotomy using patient-specific customized titanium plates. CBCT was performed Preoperative and postoperative for all patients. With the help of MIMICS and 3-MATIC softwares, were used to completed the design of the final plates, virtual planning, and diagnosis. Ultimately, the STL file was transmitted to the mill. Employed an intraoral techniques, prefabricated titanium plates were placed under GA and secured to the underlying osteomatized proximal and distal segments. Patient satisfaction was evaluated by questionnaire comparing the preoperative versus postoperative regarding both techniques. Maximal interincisal opening was measured by ruler. Dimensional stability changes were evaluated by measuring changes at B-point, menton and pogonion in relation to horizontal axis (SNx) and vertical (SNy) reference lines. Result: The study was carried out on 20 cases, 12(60%) of which were males and 8(40%) were females. The average age in study group was (20.70±1.34) years, while in control group it was (20.50±1.27) years. For patient satisfaction, there was statistically significant increase in early postoperative period demonstrated in the study group, that enhanced in both group later on Regardless maximal interincisal opening there was significant change demonstrated in study group .For all records there was statistically insignificant change in stability in both horizontal direction and upward vertical direction (p>0.05) in the study group. while the change in the control group was significantly higher (p<0.05). Conclusions: Customized titanium plates can be a reliable technique for fixation of vertical ramus osteotomy via intraoral approach in cases with skeletal class III mandibular prognanthism with high level of patient satisfaction as well as high degree of stability.
