摘要

摘要: 目的研究成年人上颌正中间隙与上唇系带附着类型的相关性，为临床中有美学诉求的患者制定合适的诊疗方案提供参考。方法 2021年9月至2021年12月招募符合要求的志愿者106名，志愿者分为2组：对照组50例，研究组（上颌正中存在间隙）56例，测量上颌正中间隙的大小，研究组分为2组：0.5～2 mm组和 > 2 mm组；分别评估上唇系带附着位置和牙龈生物型。结果对照组50名志愿者中48%为黏膜附着型，52%为牙龈附着型；研究组0.5～2.0 mm组36名志愿者黏膜附着型、牙龈附着型、及牙龈乳头型分别为33.3%、47.2%及19.5%，无跨越牙龈乳头型；研究组 > 2 mm组20名志愿者黏膜附着型、牙龈附着型、牙龈乳头型及跨越牙龈乳头型分别为10%、10%、15%及65%；经卡方检验，系带附着类型与间隙宽度比较，差异具有统计学意义（χ² = 77.176，P < 0.001），即系带附着类型在3种间隙宽度之间的分布不同。对照组中牙龈生物型50%为薄龈型，50%为厚龈型；而研究组中牙龈生物型28.6%为薄龈型，71.4%为厚龈型；2组比较，差异有统计学意义（χ² = 5.114，P = 0.024）。结论上唇系带附着类型与上颌正中间隙有关，上颌正中间隙者较无间隙者上唇系带附着位置更靠近牙龈缘， > 2 mm上颌正中间隙和跨越牙龈乳头型上唇系带显著相关。上颌正中间隙者牙龈生物型主要为厚龈型。

Abstract: Objective To find out the relationship between maxillary midline diastema and maxillary labial frenum, develop an appropriate diagnosis and treatment plan for patients with aesthetic demands in the clinic. Methods 106 qualified volunteers were recruited from September 2021 to December 2021. The volunteers were divided into two groups: 50 in the control group and 56 in the study group （with maxillary median space）. The size of maxillary midline diastema was measured. The study group was divided into two groups: 0.5～2 mm group and > 2 mm group; The type of maxillary labial frenum and gingival biotype were evaluated respectively. Results 48% of the 50 volunteers in the control group were mucosal type and 52% were gingival type. In the study group, the mucosal, gingival, and papillary type in the 0.5～2 mm group （36 volunteers） were 33.3%, 47.2% and 19.5% respectively, and there was no papillary penetrating type; in the > 2 mm group （20 volunteers）, the mucosal, gingival, papillary and papillary penetrating type were 10%, 10%, 15% and 65% respectively, Chi square test showed that there was significant difference between the attachment type of Maxillary labial frenum and the gap width （χ² = 77.176, P < 0.001）, that is, the distribution of the attachment type among the three gap widths was different. In the control group, 50% of the gingival biotypes were thin gingival type and 50% were thick gingival type. In the study group, 28.6% of the gingival biotypes were thin gingival type and 71.4% were thick gingival type. There was significant difference between the two groups （χ² = 5.114, P = 0.024）. Conclusions The attachment type of maxillary labial frenum is related to the midline diastema. The attachment position of maxillary labial frenum in patients with maxillary midline diastema is closer to the gingival margin than those without diastema. The maxillary midline diastema > 2 mm is significantly related to papilla penetrating attachment. The gingival biological type is mainly thick gingival type.
