简要总结
this study was done to evaluate clinically and radiographically four single piece inter-foraminal compressive implant connected via digitally designed co-cr milled bar with distal cantilever supporting mandibular overdenture. The evaluation will be done clinically and radiographically as following:
- Marginal bone loss
- Soft tissue changes around the implants
详细描述
Six patients of age ranging from 40 to 60years (mean 50 years) were selected for this study from the out patients clinic, Prosthodontics department, Faculty of Dentistry, Mansoura University.
I) Preparation of the patient for implant placement:
- A cone beam C.T was done for each patient to determine the bone height and the adequate sites for the placement of four interforaminal implants.
- Mandibular denture was constructed to aid in designing of surgical stent to guide in implant placement.
II) Surgical phase :
- Surgical stent was used to guide in implant placement. All implants were placed according to the flapless protocol under local anesthesia.
- All patients received four dental implants located anterior to the mental foramen in canine and premolar position.

研究组 & 干预措施
compressive one piece implants with bar attachment
All patients received 4 mandibular inter-foraminal single piece compressive implants, bar attachment connecting 4 implants was then cemented and complete mandibular overdenture was attached to bar via peek clips
干预措施: compressive single piece dental implant (Procedure)
