In 1993 the Department of implant Dentistry at New York University College
of Dentistry began a long-term clinical, histologic, histomorphometric, and
radiographic study of the sinus elevation procedure. One of the parameters
under evaluation in this study is the effect of barrier membrane placement
on the creation of vital bone in the grafted sinus cavity. This report pre
sents a histologic and histomorphometric evaluation of healing with and wit
hout the placement of an expanded polytetrafluoroethylene (e-PTFE) barrier
membrane over the lateral window at the time of sinus grafting. The data we
re collected from 12 patients who underwent bilateral sinus elevation surge
ry. In each of these 12 patients the same grafting material was used in bot
h sinuses, making the presence or absence of an e-PTFE barrier membrane the
only controlled variable. Under the conditions of this study, the results
indicate that (1) placement of the barrier membrane tends to increase vital
bone formation; (2) placement of a barrier membrane has a positive effect
on implant survival; and (3) membrane placement should be considered for al
l sinus elevation procedures.
