The relations between craniofacial morphology and dental aesthetic index(DAI) / 대한치과교정학회지

ABSTRACT

Multple features of occlusion have been combined by epodemiologists in attemps to objectively to determine malocclusion severity and treatment priorty. Jenny et al were developed DAI(Dental Aesthetic Index), which is an orthodontic index based on socially defined aesthetic stamdards. This stydy aimed to evaluate association between 10 occlusal componets of DAI and individual measures of skeletal morphology by use of univariate and multivariate analysis. In addition the relationship between a Dental Aeathetic Index score and skeletal mophology was evaluated. The data for this study were obtained from cephalometric radiographs and dental casts of 182 korean patients(79 men, 103 women) with permanent dentition who had been acccepted for the orthodontic treatment at Department of Orthodontics, Chonbuk National University. The results are as follows 1. Several occusal components of DAI(missing, crowding and spacing in the incisal segment, diastema, largest anterior irregularity on upper and lower arch) were not associated with individual measures of craniofacial morphology. 2. Sagittal occlusal components of DAI were associated with anteroposterior skeletal measures. 3. The relation between vertical occlusal components of DAI and vertical skeletal measures was low magnitude. 4. A Dental Aesthetic Index, which is based on several aspects of occlusion, did not identify craniofacial morphology. We can conclude that combination of certain occlusal components of the DAI may be related with specific skeletal morphology but, this concept could not be accepted generally.
