Sustainable practices are necessary in all areas, and in dentistry, this need is becoming increasingly present. Thus, new materials and materials become important in this process. Among these materials, biomaterials stand out. Biomaterials are natural or synthetic materials used in contact with biological systems whose purpose is to repair or replace tissues, organs or functions of the organism, with the aim of maintaining or improving the patient's quality of life. This literature review aims to examine and demonstrate the application of biomaterials, highlighting them as a viable option in dentistry. Currently, in dentistry, three categories of biomaterials stand out: metals, polymers and ceramics, with the use of Nile tilapia skin in dentistry being considered an innovation. Biomaterials must present physical and biological properties compatible with the host's biological tissues, in order to stimulate an adequate response from them. As demonstrated, the use of biomaterials in surgical procedures becomes necessary. Biomaterials, their use and innovations, as highlighted throughout this literature review, emerge as a fundamental tool in promoting quality, efficiency and sustainability in oral health services.
