简要总结
This study aims to examine dimensional alveolar ridge alterations and prevent buccal plate resorption and soft tissue recession following immediate implant placement in extraction sockets in the maxillary esthetic zone using different socket morphology-guided treatment modalities.
Expected results of the study are:
- To have found the optimal materials and GBR procedures modalities for buccal plate resorption degree reduction;
- Soft tissue recession and best esthetic result achievement. There will be possibilities to study socket morphology influence on final esthetic result achievement.
详细描述
Aim of the study: to examine dimensional alveolar ridge alterations and prevent buccal plate resorption and soft tissue recession following immediate implant placement in extraction sockets in the maxillary esthetic zone using different socket morphology-guided treatment modalities.
Objectives:
- To evaluate extraction socket buccal plate resorption rate among patients groups with immediate implant placement simultaneously with guided bone regeneration (GBR) methods using different types of bone graft materials.
- To evaluate esthetic outcome using Complex Esthetic Index (CEI) (Appendix 3) and correlate this to the initial buccal plate thickness and soft tissue biotype assessed during immediate implant placement simultaneously with GBR.
- To recommend the most appropriate method for prevention of buccal plate resorption, soft tissue recession and esthetic result achievement following immediate implant placement in extraction sockets in the maxillary esthetic zone.

结局指标
主要结局
Complex Esthetic Index (CEI)
时间窗: One year
CEI will be evaluated by two calibrated observers and mean will be calculated. Complex esthetic index is composed of three components: the soft tissue index (S), predictive index (P) and implant supported restoration index (R).
