How to deal with extraction sockets that do not show new bone formation after a normal healing period, but instead fill with connective tissue? A prospective, observational study investigates the effect of Ridge Preservation for this condition.1

According to an exploratory study about 5% of extraction sockets do not show regular healing with new bone formation inside. Even after meticulous debridement and a 12-week healing period, these sockets are mainly occupied by fibrous scar tissue.2 No treatment strategies have yet been provided for these non-healing, “erratic” extraction sockets. A prospective observational study from Italy recently investigated the effectiveness of Ridge Preservation with Geistlich Bio-Oss® Collagen in preparing the sites for later implant placement.1
 

No complications, no inflammation

Ten patients were treated with Ridge Preservation with Geistlich Bio-Oss® Collagen. The 4-month healing period was uneventful in all cases. Correct implant placement was possible, and no implant failure occurred during the observation period up to six months after loading. Samples taken at the time of implant placement did not reveal any signs of inflammation. The overall mean percentage of bone in the samples was 58% – including 28.9% residual graft and 29.1% new bone – compared to 42% connective tissue.

Geistlich Bio-Oss® Collagen is a bovine derived xenograft, enriched with porcine collagen, encompassing three characteristics: 1) flexibility to properly fit the defect, 2) ability to contain soft tissue migration, and 3) prevention to stop the wound from collapsing. Geistlich Bio-Oss® Collagen indeed combines the flexibility of purified collagen with the mechanical strength of inorganic bone substitute.1

The authors conclude: “Using bovine-derived xenograft enriched with porcine collagen without barrier membranes to treat erratic healing is a fast, easy procedure with low complication rates …the histological findings on biopsy specimens show that the treatment described in this study can induce bone regeneration, enabling implant placement.”
