上颌前牙单牙即刻种植即刻修复与延期种植修复对患者植体周围软组织和主观满意度的影响

目的 比较上颌前牙单牙即刻种植即刻修复与延期种植修复对患者植体周围软组织和主观满意度的影响。 方法 选取杭州市口腔医院收治的单颗上颌前牙种植义齿修复患者61例,依据治疗方法分为2组。即刻组患者33例给予即刻种植即刻修复,延期组28例给予延期种植修复。治疗后,采用红色美学评分(PES)评价植体周围软组织,测量牙槽骨垂直吸收量,采用视觉模拟评分法(VAS)评价主观满意度(色泽、附着高度、义齿咀嚼功能、整体美观)。并采用统计学软件对2组数据进行统计学分析,进而探讨上颌前牙单牙即刻种植即刻修复与延期种植修复对患者植体周围软组织和主观满意度的影响。 结果 2组种植成功率均为100%。修复完成时,即刻组PES显著高于延期组PES (P<0.05);修复1年时2组PES均明显升高(P<0.05),即刻组PES显著高于延期组PES (P<0.05)。修复1年时,即刻组垂直骨吸收距离显著低于延期组(P<0.05)。修复1年时,即刻组附着高度、义齿咀嚼功能、整体美观评分均显著高于延期组(P<0.05)。 结论 即刻种植即刻修复治疗单颗上颌前牙的成功率和PES与延期种植修复相当,但即刻种植即刻修复可明显改善患者牙槽骨垂直吸收以及满意度。 

Effects of immediate and delayed placement and restoration of a single anterior tooth implants on soft tissue around implant and subjective satisfaction

Objective To compare the effect of immediate and delayed placement and restoration of a single anterior tooth implants on soft tissue around implant and subjective satisfaction. Methods Sixty-one patients undergoing anterior single tooth replacement with immediate implants in our hospital were divided into immediate placement and restoration group (n=33) and delayed placement and restoration group (n=28). After the treatment, soft tissue around the implant was evaluated by the pink esthetic score (PES). The vertical resorption of alveolar bone was measured. The subjective satisfaction (color, attachment height, denture chewing function and overall appearance) were evaluated by visual analogue scale (VAS). And the statistical data were analyzed by statistical software to investigate the effects of immediate implantation and delayed implantation on the soft tissue and subjective satisfaction. Results The success rate of the two groups were 100% (P < 0. 05). PES of immediate group was significantly higher than that of delayed group (P < 0. 05). One year later, the PES of both groups were significantly improved (P < 0. 05), and the PES of the immediate group was higher than that of the delayed group (P < 0. 05); the vertical bone resorption distance of immediate group was significantly lower than that of the delayed group (P < 0. 05); the dentition height, chewing function of denture, overall aesthetic score of the immediate group were significantly higher than those of the delayed group (P < 0. 05). Conclusion The success rate and PES of immediate placement and restoration is match to that of delayed implantation, but the immediate implantation and restoration could improve the vertical absorption and satisfaction of alveolar bone.
