摘要
目的:观察上颌前牙区单个种植牙近远中龈乳头高度变化,并分析不同牙龈生物学类型对龈乳头重建的影响。方法:选择30例上前牙区单牙缺失患者,分别植入Straumann软组织水平种植体。所有患者在3个月后取模时,用直接测量方法测量种植体唇侧黏膜厚度,将其分为A组(黏膜厚度≥1.5 mm,16例)、B组(黏膜厚度<1.5 mm,14例)2组。在修复体戴入时(基线期)和6个月后(随访期)观察近、远中龈乳头充盈度,并测量龈乳头高度及龈乳头-冠接触点的距离。采用SPSS19.0软件包分析6个月后近、远中龈乳头高度的变化,比较龈乳头高度在A、B 2组间的差异。结果:所有种植体的留存率为100%。60个龈乳头的平均高度在基线期和随访期分别为(1.64±0.97)mm和(3.10±1.39)mm,平均增加(1.46±0.75)mm,具有显著差异(P<0.05)。在A组,近、远中龈乳头-冠接触点的平均距离分别为(0.15±0.24)mm和(0.23±0.33)mm,充盈度则为(97±5)%和(94±8)%;而在B组,近、远中龈乳头-冠接触点的平均距离分别为(1.94±0.40)mm和(2.10±0.34)mm,充盈度则为(53±9)%和(43±14)%。A、B两组间有显著差异(P<0.05)。结论:上颌前牙区单个种植牙修复后6个月,两侧的龈乳头高度可随着时间产生不同程度的增加,而龈乳头的增加则受不同的牙龈生物学类型的影响。其中,厚龈生物型比薄龈生物型在龈乳头重建方面有着更好的再生潜力。
PURPOSE： To observe the alteration of the interproximal papilla height after single implant restoration in the anterior maxilla and to assess the influence of gingival biotypes on papilla regeneration.METHODS： Thirty patients with single-tooth implant-supported restorations in the anterior maxilla were assigned to two groups according to labial mucosa thickness.Group A： labial mucosal thickness≥1.5 mm and group B： labial mucosal thickness1.5 mm.The presence of interproximal papilla as well as the distance between papilla apex and contact point were assessed at crown attachment（baseline） and after 6 months（follow-up）.Statistical analysis was performed using SPSS19.0 software package.RESULTS： The 6-month survival rate of implants was 100%.The mean height of interproximal papilla at baseline and follow-up was（1.64 ±0.97） mm and（3.10 ±1.39） mm,respectively.A significant improvement in papilla height was found between baseline and follow-up（P0.05）.In group A,the mean distance from papilla apex to the contact point at mesial and distal aspects was（0.15±0.24） mm and（0.23±0.33） mm,respectively,and the presence of interproximal papilla were（97±5）% and（94 ±8）%,respectively.In group B,the mean distance from papilla apex to the contact point at mesial and distal aspects was（1.94±0.40） mm and（2.10±0.34） mm,respectively,and the presence of interproximal papilla was（53±9）% and（43±14）% respectively.Statistically significant difference was found between the two groups（P0.05）.CONCLUSIONS： The interproximal papilla height around single implant restorations could improve significantly after 6-month follow-up. The interproximal papilla height around single-tooth implants in the anterior maxilla was influenced by gingival biotype. The regenerative potential of thick-gingival biotype was better than that of thin-gingival biotype.
