Abstract: Objective To evaluate the alteration of labial bone mass one year after immediate implant or delayed implant placement in esthetic zone.Methods From June 2009 to June 2012,22 patients with 11 immediate implant and 11 delayed implant in the maxillary anterior region were followed up.CBCT images were obtained immediately after surgery and one year after implant placement,the horizontal and vertical alterations of the labial bone were evaluated by image analysis software.Results The 1-year vertical reduction of labial bone after immediate implant placement was statistically significant (P＜0.05),and no significant difference in delayed implant (P＞0.05).The 1-year horizontal reduction of labial bone was statistically significant at coronal and middle of implant,without significant difference at apical of implant.Conclusions Immediate implant can not stop the physical absorption of labial alveolar ridge,and the study can provide reference to achieve esthetics in the anterior region.
