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, P0.05]. 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.Objective To investigate the feasibility of two-stage crestal approach sinus elevation in severe atrophic maxilla. Methods A total of 25 patients (male 13 cases,female 12 cases) who attended Department of Implant Center, Stomatological Hospital, Southern Medical University from May 2016 to May 2018 were included in this study. The age of the patients was 32-49 years old. The inclusion criteria were single or multiple tooth loss in posterior maxilla with residual bone height ranged from 1.5 to 3.0 mm and vertical bone width≥6 mm, no pathological changes or septum were detected in the sinus. The elevated sides were divided into three groups according to different buccal-palatal sinus width (SW) wide (16 case, SW＞15 mm), normal (12 case, 12 mm≤SW≤15 mm), narrow (5 case, SW0.05). Conclusions Two-stage crestal approach for sinus elevation might be an alternative protocol in severe atrophic posterior maxilla, especially in cases with narrow and normal buccal-palatal width. There is an urgent need for long time follow-up and more clinical cases.Objective To evaluate l
