When using PreservaRidge™ Plug, is it necessary to cover the plug with the gingival flap or a non resorbable membrane?

Can PreservaRidge™ Plug be exposed to the oral environment after placement in the extraction socket?

When filling the void, following an extraction site, using PreservaRidge™ Plug, it is best to achieve primary closure if possible. The use of a membrane is left to the clinicians discretion.
