Abstract Objective To discuss the bonding strength of Ti6Al4V porous pile made by selective laser sintering, and to provide theoretical basis for improving the bonding strength of pile core. Methods Preformed fiber piles were scanned and digital models were obtained. Ti6Al4V solid piles and porous piles were made by selective laser sintering technology, and zirconia piles were made by CAD-CAM technology. Different piles were bonded with post core resin to obtain micropush-out specimens. Micro-extrusion specimens were divided into solid pile group, porous pile group, and zirconia pile group according to material and shape, with 10 pieces in each group. The differences of bonding strength and failure of the three groups were compared by micro-extruding test. Results The bonding strength of solid pile group and porous pile group was higher than zirconia pile group, and the porous pile group was higher than solid pile group, the differences were statistically significant (P ＜ 0.05). There were statistically significant differences in damage among the three groups (P ＜ 0.05). Further pairwise comparison showed that the failure rate of adhesive interface of porous pile group was lower than that of zirconia pile group, the failure rate of internal adhesive was higher than that of zirconia pile group, and the failure rate of mixed adhesive was higher than that of zirconia pile group, with statistical significance (P ＜ 0.017). Conclusion The adhesive strength of Ti6Al4V porous pile and solid pile made by selective laser sintering is obviously improved compared with that of zirconia pile and post core resin.
