Abstract:

Objective　The aim of this studywas to evaluate the aesthetic effectiveness of implant supported dentures in partial- ly edentulous patients and the patients′satisfaction on aesthetic effectiveness.Methods　The aesthetic status of peri-implant gingi- val and the correlated soft tissue health of implant supported dentureswere investigated. The questionnaire of the patients′satisfac- tion on aesthetic effectiveness had also been collected.Results　43 interdental papillae of 22 restorations were investigated, 53. 4% of which were optimal. And the size of interdental papillae increased during the period of study, which had no relationship with plaque and gingival inflammation. The patients were satisfied with the esthetic effectiveness of implant supported dentures. Conclusion　To some extent, the interdental papillae has regeneration ability, but there are no close relationship between regen- eration and gingival inflammation. In order to acquire more aesthetic effectiveness, surgical and nonsurgical techniques should be used by clinicians.
