Dental Arch Expansion Effect of Midpalatal Cortex Ostecotomy Assisted Maxillary Skeletal Expander on Adult Maxillary Transverse Deficiency and Its Impact on Molar Inclination Angle
摘要
Abstract
Objective To investigate the dental arch expansion effect of midpalatal cortex ostecotomy(MCO)assisted maxillary skeletal expander(MSE)on adult maxillary transverse deficiency(MTD)and its impact on molar inclination angle.Methods A retrospective analysis was conducted on the data of 50 MTD patients admitted to the author's hospital from February 2019 to February 2023.According to different treatment methods,they were separated into an MSE group(24 cases)and an experimental group(26 cases).MSE group received MSE treatment,while experimental group received MCO assisted MSE treatment.The changes in maxillary basal bone width,arch width,molar inclination,and the height and surface area of each segment of the upper airway were compared between the two groups.Results After treatment,the widths of the hard palate floor maxillary,apical plane maxillary,and nasal cavity in the first molar area(M1)and first premolar area(P1),and the widths of M1 and P1 palate tips in both groups were greater than before treatment(P＜0.05),and the widths of the M1 and P1 palatal tips in the experimental group were greater than those in the MSE group(P＜0.05).The inclination of the left/right maxillary first molars(maxillary position 26/16)in both groups was higher than before treatment(P＜0.05),but there was no difference in inclination of tooth positions 16 and 26 between the experimental group and the MSE group(P＞0.05);the heights and surface areas of the oropharynx and nasopharynx in both groups were greater than before treatment(P＜0.05),and the experimental group were greater than the MSE group(P＜0.05).Conclusion MCO assisted MSE treatment for adult MTD patients can effectively expand the widths of the maxillary base bone and dental arch,reduce the risk of excessive buccal inclination of molars,and improve the height and surface area of the upper airway.关键词
