Abstract:
Objective:To evaluate the clinical effect of three-dimensional (3D) printing individualized titanium mesh for ridge augmentation in the esthetic zone.Methods:Forty-three patients were treated with personalized titanium mesh bone augmentation from Department of Oral Implantology, Stomatological Hospital of Chongqing Medical University from January, 2018 to June, 2020. According to the preoperative cone-beam CT (CBCT) data, the 43 patients [male: 21, female: 22, aged (30.1±5.8) years] were divided into three groups according to the Seibert classification as horizontal, vertical and horizontal-vertical classes (sample size: 14, 15, 14). Then, comprehensively the bone mass and esthetic requirements were taken into account to design and accordingly fabricate the 3D printing individualized titanium mesh. During the surgical process, autologous bone and xenogeneic bone substitutes were mixed at a 1∶1 ratio, combined with injectable platelet-rich fibrin (i-PRF) and individualized titanium mesh for ridge augmentation. All patients were recalled at 1, 3, and 6 months post-operation to observe the mesh exposure; the clinical effect of ridge augmentation was evaluated 6 months post-operation. After the implant placement and final restoration, the pink esthetic score (PES)/white esthetic score (WES) were evaluated.Results:Only one patient experienced early mesh exposure, and no obvious infection was observed. The bone gain regarding three types of bone defects was significantly higher immediately post-operation compared to pre-operation (horizontal, vertical and horizontal-vertical bone defect measured as (3.27±0.13), (17.41±0.46), (3.76±0.24), (14.37±0.89) mm pre-operation, respectively; and (5.25±0.15), (26.10±0.55), (6.35±0.29), (22.52±0.90) mm immediately post-operation, P<0.01). There was no obvious bone resorption 6 months post-operation [outcomes for horizontal, vertical and horizontal-vertical bone defect measured as (5.14±0.14), (25.67±0.52), (6.13±0.26), (22.35±0.89) mm, P>0.05]. The PES/WES scores of all patients were interpreted as "excellent". Conclusions:The 3D printing individualized titanium mesh is effective in repairing bone defects in the esthetic zone, and produces credible esthetic outcomes after implantation and final restoration.
