| Description: | The position of maxillary and mandibular incisors is one of the fundamental parameter in formulating an orthodontic treatment plan. The purpose of this cross-sectional study was to identify the dentoalveolar morphology features in relation to different inclination of the maxillary and mandibular incisors in Class II skeletal pattern patient using a dental cone-beam computer tomography (CBCT). A total of 180 CBCT records were collected from subjects aged between 17 to 35 years old. The subjects were then classified into its incisor inclination (procline and upright) according to the cephalometrics norms. Proclined group consist of 120 subjects for the maxillary incisors and 91 subjects for the mandibular incisors, whereas the upright group has 80 subjects for the maxillary incisors and 88 subjects for the mandibular inciors. The buccolingual thickness and alveolar bone height of the maxillary and mandibular incisors were measured using iCATVision Software Interface. Statistical analysis was done using T-Test and ANOVA. The results show that the upright group had significantly greater alveolar bone height compared to the proclined group at both maxillary and mandibular incisors (p < 0.05). The alveolar bone thickness was significantly thicker in proclined mandibular incisors (p < 0.05) compared to the upright group. In the proclined group, buccal alveolar bone height was greater at the maxillary lateral incisors than central incisors. However, in both proclined and upright group the alveolar bone thickness at A point was thicker at the maxillary central incisors compared to the lateral incisors. The lingual alveolar bone was significantly thicker at the mandibular lateral incisors than central incisors in both upright and proclined group. In conclusion, there is significant relationship between types of incisor inclination and the alveolar bone height and thickness in mandibular incisors. However there was no significant difference in the alveolar bone thickness of normally inclined and proclined maxillary incisor. Therefore it may be important to assess the inclination of incisors within its surrounding bony support prior orthodontic treatment to prevent possible damage to oral tissue.,Ijazah Sarjana Doktor Pergigian (Klinikal Ortodontik) |
