Abstract:
Objective:To compare the accuracy of dynamic navigation system,fully-guided and Pilot-drill guided implant surgery in anterior dental aesthetic area.Methods:45 patients underwent single tooth implantation in anterior dental aesthetic area were random-ly divided into 3 groups(n=15).Dynamic navigation system imlanting(A),3D printing fully-guided template with ASTRA EV assis-ted orthopedic implantation(B)and Pilot-drill guided implantation(C)were respectively used for the patients in group A,B and C.The deviation between the preoperative design and actual results were measured by CBCT and/or 3D reconstruction with navigation de-sign software or 3SHAPE software.SPSS 25.0 software package was used and(x)±s was used for descriptive analysis,results were pair-wise compared among the 3 groups using ANOVA.Results:Data were normally distributed and the variance of the data was homoge-neous.In group A,the distance deviation of implant top center was(0.571±0.196)mm,the horizontal deviation was(0.405±0.222)mm,the distance deviation of implant apical center was(0.449±0.267)mm,the vertical deviation was(0.312±0.223)mm,the de-viation of the connection angle between the two centers was 2.257°±0.989°.In group B,those were(0.520±0.242)mm,(0.219±0.201)mm,(0.643±0.284)mm,(0.464±0.292)mm and 1.272°±0.951° respectively.In group C those were(1.179±0.365)mm,(0.667±0.276)mm,(1.518±0.566)mm,(0.967±0.444)mm and 2.568°±0.632°.The deviation of all the measurments of group A and B was lower than those of group C(P＜0.05).The deviation of the connection angle between the 2 centers of group B was less than that of group A(P＜0.05),but no statistical significance(P＞0.05)was found in other 4 measured items.Conslusion:The accuracy of the dynamic navigation system and the fully-guided implantation is significantly higher than that of the Pilot-drill guided implantation,but is not statistically significant between dynamic navigation and the fully-guided system.
