Abstract: Objective To assess the esthetic effects and factors for implants of lost anterior teeth. Methods Clinical data of 134 patients who received restoration of anterior teeth from April, 2009 to December, 2010 in our hospital were analysed retrospectively. The situation of plants was followed up. Assess the esthetic effects of implants of lost anterior teeth by visual analog scale（VAS） and implant crown esthetic index（ICAI）, and analyze the factors. Results The survival ratio of implants was 98.26 % after followed-up. The score of VAS from 134 patients was（89.21±3.12）. The total average ICAI score was（1.81±0.11）from doctors. It showed that the esthetic effects of all implants were well. The esthetics was positively related to implantation methods, treatment of soft tissues around the implants (P＜0.05). There was a negative correlation between the esthetic effects and the way of incision and flap surgery(P＜0.05). Conclusion There are lots of factors that affect esthetic effects of implants. It’s necessary to choose proper ways of operation according to patients’ condition and to improve communication between doctors and patients so as to adjust factors that affect esthetic effects, so that patients’ satisfaction degree can be improved.
