title: Bone regeneration around immediate implants utilizing a dense polytetrafluoroethylene membrane without primary closure: a report of 3 cases.
abstract: Case reports document successful use of a high-density polytetrafluorethylene membrane to augment horizontal defects associated with immediately placed implants. This membrane, which is designed to withstand exposure (not require primary closure) to the oral cavity because it is impervious to bacteria, reduces the need for advanced flap management to attain primary closure. Thus, the surgical aspect is less complex and the mucogingival architecture of the area can be maintained. These cases demonstrate successful use of this application and provide evidence for controlled clinical trials to further evaluate this technique.
