Systemic ozone therapy as an adjunctive treatment in guided bone regeneration: a histomorphometrical and immunohistochemical study in rats.

Objectives: To assess the effectiveness of ozone therapy in guided bone regeneration (GBR) for critical size calvarial defects in rats.

Materials And Methods: 96 male Wistar rats were divided into four groups (n = 6 each). An 8 mm critical defect was created in the calvaria of each rat.

Inflammatory Profile of Different Absorbable Membranes Used for Bone Regeneration: An In Vivo Study.

Background: Guided bone regeneration (GBR) has become a necessary practice in implantology. Absorbable membranes have shown advantages over non-absorbable membranes, such as blood support of bone tissue. This study aimed to evaluate five collagen membranes in rat calvaria critical-size defects through a histomorphometric analysis of the inflammatory profile during the initial phase of bone repair.

Application of Tissue Engineering in Manufacturing Absorbable Membranes to Improve the Osteopromoting Potential of Collagen.

The membranes are an important biomaterial that contribute to osteopromotion. This study aimed to evaluate the osteopromotive potential of collagen membranes associated with Hydroxyapatite (HA) in critical size calvaria rat's defects. Ninety-six Albinus Wistar rats were divided into four groups: (CG) negative control: clot only (CG); positive control: porcine collagen membrane (BG); fish collagen membrane associated with HA (CP); bovine collagen membrane associated with HA (CB), analyzed at 7, 15, 30, and 60 postoperative days.

Do the New Protocols of Platelet-Rich Fibrin Centrifugation Allow Better Control of Postoperative Complications and Healing After Surgery of Impacted Lower Third Molar? A Systematic Review and Meta-Analysis.

Purpose: Platelet concentrate generation protocols have undergone several modifications in recent years; in light of these new developments, this study review aims to evaluate the effects of platelet-rich fibrin (PRF) and the new centrifugation protocols, advanced platelet-rich fibrin (A-PRF), and leukocyte platelet-rich fibrin (L-PRF), after extraction of impacted mandibular third molar. Specifically, we assessed pain control, edema, trismus, and soft tissue healing, and also measured the degree of periodontal regeneration adjacent to the second molar.

Methods: PubMed, MEDLINE, EMBASE, Web of Science, Virtual health library (BVS), and Cochrane Library were searched up to Julye 2021; randomized controlled studies were included.
