目的:分析即刻种植后修复时机对即刻种植美学效果的影响。方法:18例上颌单颗前牙即刻种植病例,唇腭侧粘膜不翻开,唇侧跳跃间隙大于1.0mm时放置骨粉,9例种植后即刻修复,9例患者采取延期修复,以近远中邻牙牙龈中点的连线为参考测量即刻种植术后3、6、12个月时间点的牙龈退缩情况。结果:9例即刻修复患者,术后3、6、12个月牙龈退缩均值是0.23±0.27,0.36±0.46,0.5±0.66,9例延期修复患者,术后3、6、12个月牙龈退缩均值0.88±0.23,1.26±0.54,1.37±0.62。讨论:上颌前牙区软硬组织量是美学修复的决定性因素,在软硬组织缺失后即使采用一些附加手术很多时候也难以达到协调的美观效果,即刻种植时在跳跃间隙内放置人工骨粉并即刻修复,可以维持天然牙龈外形,对远期美学效果具有重大促进作用。结论:即刻修复有利于软组织的存留,对维持天然牙龈外形具有促进作用。
OBJECTIVE: To analyze the effect of immediate planting restoration timing on immediate planting aesthetics. Methods: Eighteen cases of maxillary anterior teeth were implanted immediately, mucosa of lip and palate side was not opened, bone powder was placed when the labial jump gap was greater than 1.0mm, nine cases were repaired immediately after implantation, nine cases were repaired by extension, The connection of the middle point of gums was taken as reference to measure the gingival recession at 3, 6 and 12 months after immediate implant. Results: Nine patients were repaired immediately. The mean gingival recessions at 3, 6 and 12 months after operation were 0.23 ± 0.27, 0.36 ± 0.46 and 0.5 ± 0.66, respectively. There were 9 patients with delayed repairs, 3, 6 and 12 months after gingival recession Mean values 0.88 ± 0.23, 1.26 ± 0.54, 1.37 ± 0.62. Discussion: The maxillary anterior teeth hard and soft tissue volume is a decisive factor in aesthetic restoration, hard and soft tissue loss even after using some additional surgery is often difficult to achieve the coordination of aesthetic effect, immediately planting artificial skins placed in the jumping gap and immediately Repair, can maintain the natural shape of gums, the long-term aesthetics has a significant role in promoting. Conclusion: The immediate repair is conducive to the survival of soft tissue, to promote the appearance of natural gingival role.
