For evaluation of the efficiency of bone substitute, nanostructurized Gamalant-paste-FORTEPlus was placed into a mandibular defect in rats. Bone tissue reparation was evaluated after 30 days by histological methods under a microscope. Use of bone substitute in experimental mandibular defect ensured more complete and rapid restructuring of the bone tissue in comparison with the control (natural healing).

The increasing number of elderly people across the globe has led to a rise in osteoporosis and bone fractures, significantly impacting the quality of life and posing substantial health and economic burdens. Despite the development of tissue-engineered bone constructs and stem cell-based therapies to address these challenges, their efficacy is compromised by inadequate vascularization and innervation during bone repair. Innervation plays a pivotal role in tissue regeneration, including bone repair, and various techniques have been developed to fabricate innervated bone scaffolds for clinical use.

Synthetic bone transplantation has emerged in recent years as a highly promising strategy to address the major clinical challenge of bone tissue defects. In this field, bioactive glasses (BGs) have been widely recognized as a viable alternative to traditional bone substitutes due to their unique advantages, including favorable biocompatibility, pronounced bioactivity, excellent biodegradability, and superior osseointegration properties. This article begins with a comprehensive overview of the development and success of BGs in bone tissue engineering, and then focuses on their composite reinforcement systems with biodegradable metals, calcium-phosphorus (Ca-P)-based bioceramics, and biodegradable medical polymers, respectively.

Background: The purpose of this study was to review the literature on the efficacy of different surgical regenerative methods for peri-implantitis treatment.
Methods: A preliminary search was conducted in seven electronic databases. The studies included in the analysis implemented surgical regenerative treatment in at least one study group.
Artificial bone, primarily composed of calcium carbonate, demonstrates a higher resorption rate than calcium phosphate-based counterparts, suggesting potential for early bone replacement. Animal experiments using porous calcium carbonate ceramics have demonstrated bone formation superior to commercially available artificial bone after short-term implantation. Long-term implantation has yielded suboptimal results owing to resorption of both newly formed bone and implantation material.

BACKGROUND This study included 32 patients with single missing teeth and alveolar bone defects and aimed to compare outcomes from guided bone regeneration with a gelatin/polylactic acid (GT/PLA) barrier membrane and a Guidor® bioresorbable matrix barrier dental membrane. MATERIAL AND METHODS A total of 32 participants were recruited in the clinical study, with single missing teeth and alveolar bone defects, requiring guided bone regeneration (32 missing teeth in total). They were randomly divided into the GT/PLA membrane group (experimental) and Guidor® membrane group (control) by the envelope method (n=16).
