简要总结
This clinical study aims to evaluate the clinical and radiographic outcomes of immediate dental implant placement in mandibular premolar sites. Patients requiring extraction of mandibular premolars will receive immediate implant placement, with or without autogenous bone grafting, according to the study protocol.
When indicated, autogenous bone graft will be harvested using piezosurgery during the implant procedure. Participants will be followed up clinically and radiographically to assess implant stability, marginal bone level changes, and peri-implant tissue conditions over a defined follow-up period. The results of this study may help determine the effectiveness and predictability of immediate implant placement in mandibular premolar regions.
详细描述
This prospective clinical study is designed to evaluate the clinical and radiographic outcomes of immediate dental implant placement in mandibular premolar regions following tooth extraction. Patients indicated for extraction of mandibular premolars will be enrolled according to predefined inclusion and exclusion criteria.
Following atraumatic tooth extraction, immediate dental implant placement will be performed in the extraction socket. two group included, one without bone graft and the other group with autogenous bone graft from ramus . Autogenous bone grafting will be utilized according to the study protocol and will be harvested intraoperatively using piezosurgery to ensure precise and minimally traumatic bone collection.
Implant placement will be performed following standard surgical protocols. Primary implant stability will be assessed at the time of placement. Patients will receive postoperative care and instructions according to institutional guidelines.
Clinical and radiographic evaluations will be conducted during follow-up visits to assess implant stability, peri-implant soft tissue condition, and marginal bone level changes. Radiographic assessment will be performed using standardized imaging techniques.
The primary outcome measures will include implant stability and marginal bone level changes around the implant. Secondary outcome measures will include implant stability and marginal bone level changes around the implant . overall implant success rate.

结局指标
主要结局
Osseointegration success rate (%)
时间窗: 6 months after implant placement.
Implant success will be evaluated based on the absence of mobility, pain, infection, and peri-implant radiolucency around the implant.
次要结局
- Implant stability (ISQ)(At implant placement and 6 months after implant placement)
- Marginal bone loss (mm)(Baseline (at implant placement) and 4 months after implant placement)
- Implant survival rate (%)(6 months after implant placement)
- Postoperative complication (%)(Up to 6 months after implant placement.)
