Summary
Dental implants placed in fresh frozen bone (FFB) for overdentures show excellent survival and success rates. This study confirms FFB is a reliable bone graft material for dental implant procedures.
Area of Science:
- Oral and Maxillofacial Surgery
- Dental Implantology
- Bone Grafting
Background:
- Growing clinical applications of fresh frozen bone (FFB) for alveolar ridge augmentation.
- Limited research on dental implant outcomes in FFB.
Purpose of the Study:
- To evaluate the clinical outcome of dental implants placed in FFB supporting overdentures.
- To assess the survival and success rates of implants in FFB.
Main Methods:
- Retrospective study of 17 patients (2003-2006) with 60 implants in FFB.
- 17 overdentures placed (8 mandible, 9 maxilla) using various implant systems.
- Implants varied in diameter (3.25-4.3 mm) and length (11.5-16.0 mm), replacing different teeth.
Main Results:
- 100% implant survival rate with no losses observed.
- No statistically significant differences detected among implant systems, diameters, or lengths.
- Kaplan-Meier and Cox regression analyses confirmed high success rates.
Conclusions:
- Implants in FFB supporting overdentures demonstrate high survival and success rates, comparable to non-grafted bone.
- Fresh frozen bone is a dependable material for alveolar ridge augmentation.
- No significant difference in outcomes for overdentures supported by two or more implants.

01:29Bone Formation by Intramembranous Ossification
Intramembranous ossification is one of the two processes involved in the development of bones within an embryo. The flat bones of the face, most of the cranial bones, and the clavicles are formed via this process. During intramembranous ossification, the bones develop directly from sheets of undifferentiated mesenchymal connective tissue.
The process begins when mesenchymal cells in the embryonic skeleton gather together and differentiate into osteogenic cells, which then develop into...

01:40Bone Remodeling
Bone remodeling is a continuous and balanced process of bone resorption by osteoclasts and bone formation by osteoblasts. In adults, it helps maintain bone mass and calcium homeostasis. While mechanical stress can stimulate turnover as part of the normal maintenance and reparative process, several hormones also regulate bone remodeling.
