Abstract

Abstract: Objective: To evaluate the clinical effect of 3D printing personalized root titanium alloy implant in mandibular molar area. Methods: Twelve patients with mandibular molar extraction were selected. The cone beam CT was used to design the surface porous root analogue implant (RAI) and 3D printing using titanium alloy powder. After minimally invasive tooth extraction, RAI was immediately implanted into the alveolar socket. All patients were reexamined for complications such as implant loosening and pain at 3, 6, and 12 months after operation. All-ceramic crowns were restored after 3 months, and the clinical and imaging effects were evaluated at 3, 6, and 12 months after operation. Results: All 12 patients were operated successfully. There was no loosening, no pain or sensitivity, and no suppurative exudation after operation. The soft tissue around the implant showed good marginal adhesion, and there was no obvious loss of attachment. All patients were restored with all-ceramic crown at 3 months after operation. The success rate of the implant was 100% during the 1-year observation period. After functional loading, there was no significant change in the bone level of the neck of the implant and no transmission image of the root of the implant. Conclusion: 3D printing titanium root analogue alloy implant has a good clinical effect in the immediate implantation of the mandibular molar area, which can be used as one of the options for the immediate restoration of the missing molar. However, the long-term evaluation of the success rate and survival rate of the implant is needed.
