Dentists have seen significant advancements in the understanding of bone healing at the cellular and molecular level, which has led to techniques that have expanded the scope of oral implantology. In most cases, the extraction process will initiate a sequence of bony resorptive morphologic changes that may negatively alter the alveolar ridge. These changes are variable and, if significant, can eliminate the possibility of future implant placement. Therefore, it is crucial to understand the processes of repair and regeneration, and to apply their concepts to diagnosis and treatment planning with respect to the treatment of extraction sites. In this article, Dr. Resnik discusses extraction site healing, along with indications and contraindications for socket grafting.
