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.
The Heart rate is expected to decrease, as calcium influx in blocked , since the threshold membrane potential can not be reached so quickly so the action potential will take place in longer time leading to decreased heart rate.
