摘要
目的分析与探讨采用即刻种植与早期种植治疗上前牙单牙种植修复患者的临床疗效,并研究其对患者前牙美学区种植体周软组织影响。方法将2014年4月~2016年4月期间经我院诊疗46例上前牙单牙种植修复患者,采用数字表法根据治疗方案不同分成两组,每组23例。对照组给予早期种植治疗,观察组给予即刻种植治疗。观察两组基线期及治疗2年后红色美学指数(PES)、患者满意度以及种植体留存情况。结果观察组基线期边缘龈水平(1.17±0.25)分、近中龈乳头(1.60±0.42)分、远中龈乳头(1.51±0.37)分、软组织外形(0.39±0.01)分、软组织质地及颜色(0.46±0.05)分、牙槽突外形(1.19±0.21)分、美观率(56.52%)均优于对照组边缘龈水平(0.56±0.21)分、近中龈乳头(0.68±0.18)分、远中龈乳头(0.47±0.18)分、软组织外形(0.28±0.04)分、软组织质地及颜色(0.31±0.02)分、牙槽突外形(0.27±0.04)分、美观率(21.74%),差异有统计学意义(P<0.05)。两组治疗2年后PES各项评分、美观率及种植体留存情况比较无差异(P>0.05)。结论即刻种植及早期种植治疗后种植体留存情况及远期美学效果无差异,但即刻种植能够显著改善患者基线期前牙种植体周软组织美学效果,满足患者期望值。
Objective To analyze and discuss the clinical effect of immediate implant and early implant of patients with single tooth. Meanwhile to evaluate the pink esthetic outcome of single dental implants. Methods The total of 46 cases with single tooth implants from April 2014 to April 2016 treated by our hospital were included, They are divided into 23 cases in each group by digital table method: The control group was treated with early implantation, while experimental group was treated with immediate implantation. In experimental group, the implants were placed immediately into fresh extraction and immediate restored with temporary abutments and temporary crowns.The provisional prosthesis were adjusted gradually to guide the peri-implant soft tissue remodeling during healing.The implants were restored with final restorations after 4 months and assessed using pink esthetic scores(PES)and implant survival rate in the two groups at baseline and 2 years after treatment were recorded. Results The gingival margin level scores(1.17 ±0.25), mesial gingival papilla scores(1.60±0.42), distal gingival papilla scores(1.51±0.37), soft tissue scores(0.39±0.01), soft tissue texture and color scores(0.46+0.05), alveolar process scores(1.19±0.21) and aesthetic rate(56.52%) were superior to the control group at baseline. The marginal gingival level scores(0.56±0.21), proximal gingival papilla scores(0.68±0.18), distal gingival papilla scores(0.47±0.18), soft tissue shape scores(0.28±0.04), soft tissue texture and color scores(0.31±0.02), alveolar process scores(0.27±0.04)and aesthetic rate(21.74%)were statistically significant(P<0.05).After two years after the implant surgery, there was no difference in PES scores, aesthetic rate and implant retention in 2 years(P>0.05). Conclusion There is no difference in the retention and long-term aesthetic effect of implants after immediate implantation and early implantation, however, Immediate implantation can significantly improve the aesthetic effect of the soft tissue of the anterior dental implants at baseline period, and at the same time, they can meet the patient's expectations.
