摘要/Abstract

摘要： 目的: 比较平台转移和平台对接两种种植体连接方式在上前牙区早期种植对种植体周围软硬组织的影响及美学效果。方法: 选取2017年1月至2017年12月于青岛大学附属医院口腔种植科就诊行上前牙早期种植的患者40例,随机分为A（平台转移组,植入Nobel Active种植体）、R（平台对接组,植入Nobel Replace种植体）两组,每组20例,于术后即刻、术后6个月、永久冠修复后12个月拍摄CBCT,测量术后6个月、永久冠修复后12个月CBCT种植体颈部近远中、唇腭侧骨吸收量,冠修复后12个月进行粉色美学评分（PES评分）,以及牙周软组织状况检查,并对结果进行统计分析。结果: 1）平均骨吸收量：术后6个月：A组近远中（0.25±0.12）mm, 唇腭侧（0.28±0.13）mm ;R组近远中（0.30±0.12）mm,唇腭侧（0.29±0.15）mm,差异均无统计学意义（P>0.05）。永久冠修复后12个月：A组近远中（0.38±0.14）mm, 唇腭侧（0.52±0.17）mm ;R组近远中（0.70±0.19）mm,唇腭侧（0.77±0.18）mm,差异均有统计学意义（P<0.05）。2）粉色美学评分：A组（10.90±0.89）分, R组（0.48±1.12）分,差异无统计学意义（P>0.05）。3）永久冠修复12个月后软组织情况：6个位点平均PD（mm)A组（1.98±0.53）mm, R组（2.75±0.75）mm;改良菌斑指数（mPLI)A组（0.81±0.93）,R组（1.34±0.53）;改良龈沟出血指数（mSBI)A组（0.61±0.19）,R组为（0.98±0.41）,差异均有统计学意义（P<0.05）。结论: 平台转移和平台对接两种种植体连接方式在上前牙种植修复中均具有较好的临床修复效果,同时具有平台转移的种植体能更有效地保存种植体颈部周围的软硬组织。

Abstract: Objective: To compare the effect of platform switching and butt-joint implant system on soft and hard tissues around implants in early implantation of upper anterior teeth. Methods: 40 patients with early implantation of upper anterior teeth were randomly divided into two groups: A(platform switching group, implant Nobel Active implant), R(butt-joint group, implant Nobel Replace implant) and 20 patients in each group. CBCT was taken at immediately after operation, 6 months after operation and 12 months after permanent crown restoration. Bone absorption of implant neck, lip and palate was measured at 6 months and 1 year after permanent crown restoration. Pink esthetics score(PES score) was performed after crown restoration. Periodontal soft tissue condition was examined at 12 months after restoration, and the results were analyzed statistically. Results: 1) Average bone resorption: 6 months after operation: in group A, the distal and near(0.25±0.12)mm, the lip and palate (0.28±0.13) mm, in group R, the distal and near(0.30±0.12)mm and the lip and palate(0.29±0.15)mm, there was no significant difference(P>0.05). 12 months after permanent crown restoration: in group A, there were significant differences in proximal and distal(0.38±0.14)mm, lip and palate(0.52±0.17)mm), distal (0.70±0.19)mm and lip and palate (0.77±0.18)mm in group R(P<0.05). 2) Pink aesthetic score: group A(10.90±0.89) score, group R(0.48±1.12) score, there was no significant difference (P>0.05). 3) Soft tissue condition after 12 months of permanent crown restoration: 6 sites average PD(mm) A group (1.98±0.53)mm, R group(2.75±0.75)mm, improved plaque index (mPLI) A group(0.81±0.93), R group(1.34±0.53), improved gingival sulcus bleeding index(mSBI) A group (0.61±0.19), R group (0.98±0.41), the difference was statistically significant(P<0.05). Conclusion: Platform-switching and butt joint implants can both acquire good clinical outcomes in early implantation of upper anterior. However, platform-switching is more bebificial for marginal bone and tissue preservation around dental implants.
