Biomateriais bifásicos utilizados como substitutos ósseos em procedimentos de levantamento do seio maxilar

Abstract

Introduction: Crestal bone elevation aims to provide adequate bone for dental implant therapy, focusing on stability and aesthetics. Placing implants in areas with severe alveolar resorption is challenging and impacts treatment success. The maxillary sinus, the largest of the paranasal sinuses, presents specific challenges due to its variable anatomy. Maxillary sinus lifting procedures are often used for cases of insufficient bone height. Graft materials, such as autogenous, allogeneic, xenogeneic, and alloplastic bone grafts, have been used for bone regeneration. The combination of hydroxyapatite and β-TCP is a popular alternative, offering support and osteoconductive properties. Objectives: The objective of this research is to analyze the scientific literature on the clinical performance of different proportions of biphasic graft material in maxillary sinus lifting. It aims to provide guidance to surgical professionals in choosing the most suitable material, aiming to improve clinical outcomes and prognosis of this procedure. Materials and Methods: An investigation was conducted using the
Medline/PubMed®, Scopus, and Embase databases until March 2024, employing a variety of search terms. Selected articles from this search were identified as essential reading. Relevant data were then summarized and organized into tables for further analysis. Results: The studied materials exhibit essential characteristics, such as serving as a scaffold for space maintenance, having adequate porosity for interconnectivity and vascular invasion, and mechanical properties similar to the tissue to be regenerated. In summary, biphasic biomaterials have the potential to improve bone regeneration procedures, promoting the formation of new bone and integration of dental implants, essential for the success of these procedures. Conclusion: The application of biphasic biomaterials in bone regeneration is promising, with safety properties and tissue integration capability.
