Purpose: The aim of this systematic review was to estimate if an antibiotic prophylaxis regimen reduces implant failure and postoperative infection in healthy patients who are going to receive dental implants.

Materials And Methods: An electronic database search (MEDLINE/PubMed, Scopus, Web of Science, Cochrane Library) until June 30, 2019, for randomized controlled trials (RCTs) was performed. The Cochrane Handbook for Systematic Reviews of Interventions to assess the risk of bias in individual studies was used.

Selection of Collagen Membranes for Bone Regeneration: A Literature Review.

Several treatment modalities have been proposed to regenerate bone, including guided bone regeneration (GBR) where barrier membranes play an important role by isolating soft tissue and allowing bone to grow. Not all membranes biologically behave the same way, as they differ from their origin and structure, with reflections on their mechanical properties and on their clinical performance. Collagen membranes have been widely used in medicine and dentistry, because of their high biocompatibility and capability of promoting wound healing.
