简要总结
The aim of this study is to clinically and radiographically evaluate the dimensional changes of soft and hard peri-implant tissues around single immediate post-extraction implants in the esthetic zone.
详细描述
to compare the efficacy of the socket shield technique in counteracting the dimensional changes of the soft and hard peri-implant tissues to filliing the buccal gap with xenograft. * Population (P): Patients with single non-restorable tooth in the esthetic zone. * Intervention (I): Immediate implant placement with socket shield technique. * Comparator (C): Immediate implant placement and filling the buccal gap with xenograft. * Primary Outcome (O): Pink Esthetic Score (PES) (Fürhauser et al., 2005). * Time frame: 9 months (Chu et al., 2015). * Study design: Randomized controlled clinical trial.

- •Any disease that might affect bone metabolism as osteoporosis.
- •Patients taking medications that might affect bone turn over as bisphosphonates.
- •Physically or mentally handicapped patients.
- •Pregnant females.
- •Teeth with vertical root fractures on the buccal aspect

结局指标
主要结局
pink esthetic score
时间窗: 9 months
Pink esthetic score evaluates the soft tissue esthetics around implant supported crowns. Using a 0-1-2 scoring system, 0 being the lowest, 2 being the highest value. The maximum achievable PES is 14. 7 variables are measured: mesial and distal papillae being 0 if absent, 1 if incomplete and 2 if complete. Alveolar process, soft tissue level, contour, texture and color being 0 if major discrepancy, 1 if minor discrepancy and 2 if matches the contralateral
次要结局
- Corono-apical peri-implant bone dimensional changes(6 months)
- Bucco-lingual peri-implant bone dimensional changes(6 months)
- Recession of the buccal peri-implant mucosa(9 months)
- Patient satisfaction: VAS(9 months)
