Introduction: 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. اجريت هذه الرساله علي 20 مريضا لقياس مدى رضى المرضى عند ترجيع الفك السفلي بالقطع العمودى الفموى للرأد مع التثبيت باستخدام شريحه مخصصه وبين التثبيت بين الفكين في مرضى تقدم الفك السفلي (تجربة عشوائية مضبوطة)
تم عمل الشريحه من خلال التخطيط الافتراضي باستخدام برنامج MIMICS و 3-Matic متبوعا بخرط اللوحه .تم ادخال اللوحه وتثبيتها في جزء الرأد العظمي باستخدام الشرائح الصغيره.وكان رضا المرضي النتيجه الاوليه التي تم تقييمها باستخدام الاستبيان.وكان استقرار اللوحات المخصصه هو النتيحه الثانويه بعد العمليه الجراحيه مقارنه بتدابير ما بعد الجراحه مباشره في الابعاد الافقيه والرأسيه. وكان الحد الاقصي للفتح بين القاطع هو النتيجه الثانويه بعد العمليه الجراحيه التي تم قياسها بواسطه المسطره.
خضع جميع المرضي للشفاء غير النهائى طوال فترة المتابعه بعد العمليه الجراحية. وفيما يتعلق برضا المرضي كانت هناك زياده ذات دلاله احصائيه في درجات ما بعد الجراحه من الرضا العام في كلا المجموعتين.
فيما يتعلق بفرق الثبات بين نتائج فترات المتابعه ونتائج ما بعد الجراحه المباشرة في جميع الابعادز فأنها غير ذات دلاله احصائيه في مجموعه الدراسه مما يشير الي درجه عاليه من دقة الاجراء والتثبيت الفوري للقطاعات التي تمنع الحركه .علي عكس المجموعه الضابطه , كان هناك فرق ذو دلاله احصائيه في كلا الأبعاد الأفقيه والأسيه التي قد تكون بسبب الترهل اللقمى.
