Abstract:
Objective To analyze the effect of custom abutment and computer aided design and computer aided manufacturing(CAD/CAM) provisional crown on gingival shaping around the implant,and to research the main effect of the custom abutment in the formation of gingival.Methods According to the wishes of patients,fifteen patients were divided into two groups.Gingival molding used CAD/CAM in the observation group(n=7) to design and make custom abutment and provisional crown.The control group(n=8) used the prefabricated abutment and the hand-made self-curing resin temporary crown.Immediately after inserting of final insertion and three months later,pink esthetic score(PES) was calculated in both two groups.Results The labial gingiva curve of the observation group was (1.93±0.27)points,which was higher than (1.56±0.51)points of the control group,there was significant difference between the two groups(t=2.496,P<0.05).After permanent repair of 3 months,the PES scores of the two groups[the observation group (8.71±0.95)points,the control group(8.25±1.04)points]were higher than those of permanent repair day[the observation group (8.29±1.25)points,the control group(7.25±1.04)points],there were statistically significant differences in the total score of PES and permanent repair group permanent repair after 3 months of the day(t=4.290,P<0.05),there was no significant difference between the experimental group(P>0.05).The PES score of the observation group was (8.50±1.09)points,which was higher than (7.75±1.13)points of the control group,but the difference was not statistically significant(P>0.05).Conclusion The effect of the custom abutment on curvature of facial mucosa is significant.The combination of custom abutment and digital provisional crown can achieve better soft tissue stability and ideal aesthetic effect in a short time.
