GUIDED TISSUE REGENERATION USING A BIODEGRADABLE BARRIER MEMBRANE FORNEW ATTACHMENT - A CLINICAL, HISTOLOGIC, AND HISTOMETRIC STUDY IN DOGS

Although nonbiodegradable barrier membranes have proven partially succ essful in achieving regeneration of lost periodontium through the prin ciples of guided tissue regeneration, their use requires a second surg ical procedure for their removal. The results of a study, in which a b iodegradable collagen membrane was used to treat dehiscence defects in dogs, are presented. The membrane was an effective barrier to the dow ngrowth of gingival epithelium during the early stages of healing and tended to increase the regeneration of new cementum and connective tis sue attachment. It was also biocompatible and biodegradable.
