Question

comparison of dehydrated human amnion-chorion and type 1 bovine collagen membranes in alveolar ridge preservation: a clinical and histological study

Answer 1

Alveolar ridge preservation maintains ridge dimensions and bone quality to randomized controlled clinical studyand  to compare the use of a human amnion-chorion membrane to a collagen membrane in an exposed-barrier ridge preservation technique.

• demineralized freeze-dried bone allografts used to graft the socket and primary closure
• The clinical ridge dimensions were measured after extraction and at the time of delayed implant placement. No significant difference was observed in the mean vital bone formation between the experiment
• The bone height and width did not differ, as determined by clinical measurements
• either a human amnion chorion membrane or type 1 bovine collagen,  the open barrier were not  change healing and compromises ridge dimensions, or affect bone vitality between the 2 groups.
