Summary
Guided bone regeneration (GBR) using Orthoblast II and Ossix membranes promoted significant new bone formation. This bone grafting technique demonstrated increasing bone remodeling and maturity over a 6-month healing period.
Area of Science:
- Dental Implantology
- Periodontology
- Biomaterials Science
Background:
- Guided bone regeneration (GBR) is crucial for bone defect repair around implants.
- Evaluating novel biomaterials for GBR is essential for improving clinical outcomes.
- Dehiscence defects often require bone grafting for successful implant integration.
Purpose of the Study:
- To assess new bone formation after GBR using a specific composite material.
- To evaluate the efficacy of Orthoblast II and Ossix membranes in bone regeneration.
- To analyze bone remodeling and graft resorption over time.
Main Methods:
- A prospective study involving 14 patients requiring bone grafting for dehiscence defects.
- Biopsy specimens were obtained after 4- and/or 6-month healing periods.
- Histomorphometric analysis was performed using a computer-assisted imaging system.
Main Results:
- Significant new bone formation (12.3%-78.7%) was observed.
- Bone formation and remodeling increased with healing time.
- Grafted materials showed partial resorption with evidence of ongoing bone maturation.
Conclusions:
- GBR with Orthoblast II and Ossix membranes supports favorable bone formation.
- Increasing woven bone to lamellar bone ratios indicate progressive bone remodeling.
- The study provides evidence for continuous resorption of grafting materials and bone maturation.

Bone 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.
The Bone Matrix
Bone contains a relatively small number of cells entrenched in a matrix of collagen fibers that provide an adherent surface for inorganic salt crystals. Both components of the matrix, organic and inorganic, contribute to the unusual properties of bone. Without collagen, bones would be brittle and shatter easily. Without mineral crystals, bones would flex and provide little support. This can be observed by an experiment: when the minerals of a bone are dissolved by soaking the bone in acid or...
