Journal of Oral Implantology – After tooth extraction, alveolar ridge collapse can cause serious dental complications in patients for future implant surgeries. Preservation of the alveolar ridge helps to secure bone structure essential for the eventual successful dental implant placement. Traditionally, a type-1 bovine collagen membrane has been used to strengthen the ridge, but researchers are looking into alternative materials to assist in healing, function, and esthetics. “Jawbone preservation after tooth removal maintains the bone’s volume and quality for future implant placement,” researchers from the College of Dentistry, University of Kentucky, Lexington, and a private dental practice, Houston, Texas, state. They recently published the findings of their randomized controlled clinical study in the Journal of Oral Implantology that evaluates the use of human amnion-chorion membrane compared with a traditional type-1 bovine collagen membrane in an exposed socket preservation technique.
In their analysis, the researchers identified 43 patients that needed tooth extraction followed by a delayed implantation procedure. The patients were split into a 21-person experimental group receiving a human amnion-chorion membrane (experimental) and a 22-person control group receiving a bovine collagen membrane (control). The researchers wanted “to determine if intentional membrane exposure compromises ridge dimensions and bone quality.”
Researcher Ahmad Kutkut summarized the results by stating, “The volunteers underwent implant placement after an average healing period of 19.5 weeks. Core bone specimens were obtained for histomorphometric analyses. In addition, the clinical ridge dimensions were measured after extraction and at the time of delayed implant placement. As a result, no significant difference was observed between the experimental and control groups in the quality of the vital bone formation. In addition, the bone height and width did not differ, as determined by clinical measurements.”
The findings of this study suggest that using a human amnion-chorion membrane to aid in alveolar ridge preservation had no significant difference from using the traditional type 1 bovine collagen membrane. The researchers stated that future studies should also focus on membrane thickness as well as examining residual concentrations of various grafting materials after epithelial closure.
Dr. Kutkut reiterates these conclusions by saying, “Using a human amnion-chorion membrane as an open barrier did not compromise the healing or affect bone quality and quantity at the extraction sites.”
