简要总结
This study will monitor the effect of soft tissue augmentation using sub-epithelial connective tissue graft buccal to extraction sockets in anterior maxilla in thin dento-alveolar phenotype; and will evaluate whether it will enhance the alveolar ridge contour and improve the gingival phenotype following atraumatic extraction compared with no treatment at all in terms of Ridge contour Preservation for future esthetically acceptable fixed prothesis.
详细描述
The aim of this study is to assess the alveolar ridge contour after soft tissue augmentation using sub-epithelial connective tissue graft buccal to fresh extraction sockets in patient with thin buccal bone, versus atraumatic extraction with no soft tissue augmentation.
Group A: Patients receiving atraumatic extraction with soft tissue augmentation by sub-epithelial connective tissue graft buccal to extraction sockets.
Group B: Patients receiving normal atraumatic extraction with no soft tissue augmentation
Clinical examination:
- Evaluation of the patient's general condition of the oral cavity, to make sure it complies with the criteria required to be enrolled in the study in terms of oral hygiene and pathological conditions.
- Evaluation of the buccal bone thickness using CBCT as diagnostic aid. (After CBCT if the patient was excluded because of thick buccal bone, he/she will be referred for implant placement)
- Evaluation of gingival phenotype before extraction using visual technique via periodontal probe.
- After patient enrollment, full mouth scaling to be done first and home oral hygiene measures to be done by patient. At the day of the surgery, immediately before extraction, an impression will be taken using alginate material and wax molded stock tray for recording the original ridge contour as the baseline data. casts will be made with dental extra hard stone.

结局指标
主要结局
Buccal soft tissue contour
时间窗: 6 Months
Volumetric analysis using pre and post impressions and a digital software (V.Vanhoutte, et al. 2013) (Van Nimwegen, et al 2018). The soft tissue contours of the extraction sites will be assessed quantitatively. Impressions will be taken at 3 time-points, that is, before tooth extraction (baseline, T0) and 3 (T1), and 6 (T2) months after surgery. Plaster casts will be generated subsequently and digitised with a laser scanner. For the final analyses, CAD software is to be used to match the corresponding follow-up states (T1 to T2) with the baseline state (T0) and evaluate sections at defined positions with standardization of the apico-coronal dimension of SCTG.
