Minimally Invasive Surgical Technique in Periodontal Regeneration: A Randomized Controlled Clinical Trial Pilot Study.

The purpose of this study was to compare two minimally invasive surgical techniques (MISTs) for the treatment of periodontal defects: (1) guided tissue regeneration (GTR) using resorbable minimembrane and particulate xenograft (DBBM); and (2) inductive periodontal regeneration (IPR) using enamel matrix derivatives and DBBM. A sample of 20 infrabony periodontal defects in 20 patients were randomly assigned to either the GTR or the IPR group. A follow-up was performed at 12 months postoperative.
