Abstract:

BACKGROUND: Conventional implantation at anterior aesthetic region is difficult to achieve ideal three-dimensional position, and needs high implantation accuracy.

OBJECTIVE: To evaluate the clinical application effect of three-dimensional printed digital guide technology in anterior dental implant.

METHODS: Eighty-six cases of dental implants were divided into two groups. Control group (n=43, 52 implants) received conventional dental implantation. Trial group (n=43, 52 implants) received implantation under three-dimensional printed digital guides. The accuracy of the three-dimensional position of the implants was measured. The modified plaque index, modified bleeding index, probing depth and the satisfaction of patients with implant denture were measured at 6 months after implantation.

RESULTS AND CONCLUSION: (1) The errors of vertical and horizontal directions at the top and the root after implantation in the trial group were significantly fewer than those in the control group (P < 0.05). (2) The modified plaque index, modified bleeding index, and probing depth in the trial group were significantly lower than those in the control group (P < 0.05). (3) The satisfaction of patients in the trial group was 98% (42/43), which was higher than 86% (37/43) in the control group. (4) In summary, three-dimensional printed digital guide plate used in dental implant dentures can improve the three-dimensional position accuracy after implantation and improve the postoperative clinical effect.
