摘要
目的:观察经临时冠牙龈成型后的上前牙种植修复负重1年后的牙龈形态学变化,探讨临时冠对牙龈组织进行干预的可靠性。方法:选择北京大学口腔医院第二门诊部2010年3月至2011年11月间因上前牙缺失要求种植修复的患者78例(男37例,女41例),在行种植上部修复前采用种植体支持的临时冠进行牙龈形态的诱导,直至永久修复完成。在修复即刻及1年后测量近、远中牙龈乳头及唇侧龈缘水平高度的变化。结果:所有病例在经过牙龈成型后再进行种植上部修复,修复1年后近、远中牙龈乳头高度变化分别为(0.16±0.58)mm和(0.10±0.53)mm,唇侧牙龈水平变化仅为(0.10±0.41)mm。经临时冠诱导成型后的牙龈形态在种植修复1年前后的变化差异无统计学意义(P>0.05)。结论:严格掌握适应证,采用种植体支持的临时冠在前牙美学区的种植修复中对软组织的成型技术临床可行,近期美学效果可靠。
Objective：To observe the gingival contour and its variation following application of implantsupported temporary crowns on gingival contour in maxillary single tooth implant procedure after loading 1 year and to explore the reliability of soft tissue intervention using temporary crowns.Methods：In 78 （37 males and 41 females） patients with anterior maxillary single tooth loss from the Department of Second Dental Center,Peking University School and Hospital of Stomatology,the gingival contour was induced by using implant-supported temporary crowns prior to maxillary tooth implant till permanent restoration from March 2010 to November 2011.The gingival papilla height and labial gingival margin level were measured immediately after the permanent restoration and 1 year later.Results：In all the cases after loading 1 year,the average mesial and distal gingival papilla heights in the implant area increased by （0.16 ±0.58） mm and （0.10 ±0.53） mm,respectively.The labial gingival margin level was changed by （0.10 ±0.41） mm averagely.The difference in gingival contour shaped by temporary crown was not statistically significant after 1 year （P ＞0.05）.Conclusion：The soft tissue shaping technique on aesthetic rehabilitation in maxillary single tooth implant is clinically feasible with a good recent aesthetic effect under the condition that the complications are controlled stringently.
