This study was carried out aiming to investigate the accuracy of
measurements , differences in linear and angular measurements of
the craniofacial complex using both the two and three dimensional
method of measuring in patients with different kind
s of
malocclusion ; and also to compare each kind of malocclusion to
the others. The sample of the study consisted of 40 patients ,
divided into three groups – a group for each skeletal malocclusion
, Cone Bean Computed Tomography (CBCT) was performed for
each patient , then two dimensional radiographs were derived from
the CBCT ; after performing the measuring , collecting the results
and analyzing them statistically.
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 stu
dy, 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.
