إن التحاليل السيفالومترية لنماذج المركب القحفي الوجهي مهمة بسبب أن هناك نسبة كبيرة من الحالات المترافقة مع معاوضة سنية تخفي شدة سوء الإطباق الموجود. و هناك جدل واسع حول القيم االمتوسطة التي يجب استخدامها لمقارنتها مع كل حالة فردية . في هذه الدراسة تم استخدام طريقة الانسجام المتعدد الذي يساعد في التخطيط للعلاج. تم الاستعانة بأرشيف ل 75 سوري بالغ [ 35 ذكر 40 أنثى ] و متوسط أعمار 23 سنة لم يتلقوا أي علاج تقويمي سابق من أرشيف المرضى المراجعين لقسم تقويم الأسنان و الفكين في جامعة تشرين في سورية . أفراد العينة لديهم علاقات رحوية صنف أول حسب أنجل و الازدحام أقل من 4 مم و بروز و تغطية طبيعيين و وجه متوازن لا يوجد تشوهات .
باستخدام معامل الانحدار المتعدد تم التوصل لمعادلات تعطينا القيمة المتنبأة لكل متغير و من ثم تتم مقارنتها مع القيمة الموجودة لدى المريض , إن الفرق بين الزاويتين [القيمة المتنبأة و القيمة الموجودة] يسمى باقي و هذا الباقي يشير إلى مدى الانحراف عن القيم المنسجمة حسب كل متغير . الانسجام المتعدد بإمكانه أن يكون أداة داعمة في التشخيص لطبيب التقويم و في التخطيط للعلاج .
All the analysis of craniofacialpatterns is essential since a considerable amountof
dental compensation can mask the severity of a malocclusion. Disagreement prevails over
the standards that should be used to judge the individual values.In this study, a method is
presented—the multiharmony method [MHM], which assists in treatment planning.The
approach was applied to a data set of 75 Syrian adults [35 males and 40 females, mean age
23 years] that had not received orthodontic treatment. They were selected frompatients
enrolled at Tishreen University Dental colleage, Lattakia, Syria. The subjects had an ideal
or near-ideal occlusion [Class I molar relationship, not more than 4 mm overbite and
overjet, and no missing teeth] and a well-balanced face.With multiple regression analysis,
the expected value that each angle should take in a norm individual when the remaining
angles are given is estimated. The residual difference between the measured angle and its
expected value then indicates the deviation from a harmonic appearance in the respective
angle. The MHM can serves as a supportive tool for the orthodontic expert in the
diagnosiss and decision for potential treatment.
