Abstract: 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.
