即刻种植和早期种植对前牙美学区种植体周软组织影响的对比研究

目的 对比研究种植体即刻种植和早期种植对前牙美学区种植体周软组织的影响.方法 22例单颗前牙缺失病例,A组12例,拔牙后即刻植入Zimmer TSV种植体;B组10例,拔牙后早期植入Zimmer TSV种植体.A、B两组在种植体植入6个月后氧化锆全冠永久修复.修复后6~12个月复查,测定红色美学评分(pink esthetic score,PES).对数据进行统计学分析.结果 修复后6~12个月,PES总分整体均数为9.27(美学效果可接受).即刻种植组与早期种植组之间,PES总分、单个PES评分点之间的差异无统计学意义(P>0.05).在各个PES评分点中,近、远中龈乳头高度与缺牙原因,远中龈乳头、牙槽骨缺损与牙龈生物型,唇侧牙龈高度与缺失牙位具有显著相关性.结论 即刻种植和早期种植对前牙美学区软组织美学效果的影响无显著差异.前牙美学区种植修复时,软组织美学效果受缺牙原因、牙龈生物型、缺失牙位的影响.

A comparative study between the immediate and early implant on the aesthetic influences of the peri-implant soft tissues in the aesthetic area

Objective The aim was to compare and document the aesthetic influences on peri-implant soft tissues between the immediate and early implant placement in the aesthetic area. Methods 22 patients with single anterior teeth missing were included and divided into 2 group. Group A (12cases):Following the extraction of teeth, 12 Zimmer implants were immediately placed into sockets. Group B (10 cases): 4~8 weeks after the extraction, 10 Zimmer im-plants were early placed into the healing sockets. Zirconia crowns were applied on the implants 6 months later after im-plantation. The peri-implant soft tissues in both group were examined and evaluated by pink esthetic score (PES) 6~12 months later. Analysis of the data was performed by software SPSS 13.0. Results The mean PES was 9.27 (clinical ac-ceptance) for all of the implants. No significant were found for any of the parameters between the treatment modalities regardness of total PES or single PES. However there were significant differences in the following aspects: the correla-tion between periodontal disease and papilla, the correlation between gingival biotype and mesial papilla, the correlation between gingival biotype and alveolar process deficiency, the correlation between Implant location and midfacial soft tis-sue level. Conclusion There are no significant differences between immediate placement and early placement on the aesthetic outcome of peri-implant soft tissues. The aesthetic outcome are related to patients oral health condition and cli-nicians skills.
