Abstract
Objective To analyze the relationship between the morphology of labial bone plate of teeth in the maxillary aesthetic area and overbite and overjet based on cone beam computed tomography(CBCT).Methods A total of 125 individuals who received oral examination at Xinjiang Uygur Municipal People's Hospital from January 2020 to October 2023 were selected as the research subjects.A total of 230 maxillary central incisors were examined with CBCT.The thickness of the labial bone plate,crest height,crown-to-root ratio,angle between the alveolar bone and the long axis of the tooth,labial undercut,overbite and overjet were measured using the software included in the system.Results The thickness of labial bone plate of the 230 maxillary central incisors was(1.12±0.34)mm,and the crest height was(2.01±0.89)mm.The depth of overbite and overjet was(3.08±1.17)mm and(3.66±1.29)mm,respectively.The crown-to-root ratio of maxillary central incisors was 0.94±0.21,and there were statistically significant differences between the crown-to-root ratio classification and overbite classification(P＜0.05).The angle between the alveolar bone and the long axis of the maxillary central incisor was(15.68±4.73)°.There were statistically significant differences among the angle classification between the alveolar bone and the long axis of the tooth,overbite classification and overjet classification(P＜0.05).There were statistically significant differences in the occurrence of labial undercut of the maxillary central incisor and the position of the most concave point compared with overbite classification(P＜0.05).Conclusion There is a significant relationship between the morphology of labial bone plate of teeth in the maxillary aesthetic area and overbite and overjet.When conducting immediate implantation in clinical practice,attention should be paid to the specific shape of labial bone plate of the teeth to reduce risk.关键词
