title: Clinical and microbiological observations of early polytetrafluoroethylene membrane exposure in guided bone regeneration. Case reports in primates.
abstract: Premature membrane exposure at one week is described in 3 Macaca mulatta monkeys as part of a sequence of experiments on guided bone regeneration. Clinical sequelae include redness, edema, and tissue slough. Bacteroides fragilis, Streptococcus pneumoniae, Prevotella intermedia, and Staphylococcus intermedius were detected at all prematurely exposed sites. Pseudomonas maltophilia, Strept, pneumoniae, and P. intermedia were the predominant organisms detected and consisted of more than 10% of the total anaerobic count.
