简要总结
Twenty-nine patients needing single tooth replacement in aesthetic area were treated by extraction and socket preservation with saddle connective tissue graft between September 2009 and February 2012. Computed Tomography scan were taken at baseline just after the surgery and 3 months later. Long- term evaluation of this particular socket management procedure was evaluated by recalling successfully seventeen of theses patients in June 2016. At this time, a clinical and radiographical consultation was done and Cone Beam CT was taken. Horizontal and vertical bone dimensional changes were then assessed thanks to 3D imaging analysis and esthetic and implants outcomes were evaluated.

结局指标
主要结局
Changes from Baseline Alveolar bone remodeling to 3 months and 6 year : vertical measurements (based on CBCT, in mm)
时间窗: Baseline, 3 months, 6 years
The measurement were done by matching and superimposing CT scans using a three dimensional reconstruction software. One vertical measurement was taken on the buccal side, in parallel to the vertical reference line at mid distance between the buccal wall and reference line.
Changes from Baseline Alveolar bone remodeling to 3 months and 6 year: horizontal measurements (based on CBCT, in mm)
时间窗: Baseline, 3 months, 6 years
The measurement were done by matching and superimposing CT scans using a three dimensional reconstruction software. Palatal horizontal measurements were calculated by subtracting the buccal horizontal measurements from the total horizontal measurements.
次要结局
- Implant survival rate (based on criteria of Buser et al., 1990)(Approximatively 6 years)
- Esthetic outcomes (PES questionnaire)(Approximatively 6 years)
- Esthetic outcomes (VAS questionnaire)(Approximatively 6 years)
- Peri-implant bone levels (based on periapical radiography, in mm)(Approximatively 6 years)
