Biomaterials play a crucial role in periodontal treatment by providing scaffolds for tissue regeneration, enhancing wound healing, and promoting the integration of dental implants. These materials, often derived from natural or synthetic sources, are engineered to mimic the properties of the surrounding tissues and promote favorable biological responses. Common biomaterials used in periodontal treatment include bone grafts, membranes, and growth factors, which aid in restoring lost tissue and promoting long-term oral health. Their innovative application continues to advance periodontal therapy, offering patients improved outcomes and enhanced quality of life. This book covers the biomaterials available commercially and its application in various periodontal treatment.
