简要总结
The aim of this study is to investigate how a socket preservation procedure may reduce the need of guided bone regeneration surgery after tooth extraction and facilitate the placement of a dental implant in the optimal, prosthetic-driven position.
详细描述
The main gol of the study is to assess the efficacy of a socket preservation procedure in reducing the need of additional surgeries in order to augment alveolar bone volume before placing a dental implant in optimal position. Bone volume at 6 months will be compared to initial volume in order to assess volume variations and how they affect the positioning of a prosthetically driven, implant.

结局指标
主要结局
Number of implants ideally placed
时间窗: 6 months
The main goal is to determine if alveolar ridge preservation affects optimal implant positioning. This is defined as the implant position allowing to fulfill the ideal prosthetic design of the crown to be restored.
次要结局
- Ridge volume at 6 months after tooth extraction(6 months)
- Peri-implant bone variation(6 months)
