What is guided bone regeneration (GBR)?

Guided bone regeneration (GBR) is a technique specifically used in oral and maxillofacial surgery to promote bone growth in areas where there is an insufficient volume of bone to support dental implants or other surgical procedures. This technique typically involves the use of barrier membranes and bone graft materials to create a conducive environment for the regeneration of bone tissue.

During a GBR procedure, the area where bone needs to be regenerated is carefully prepared, and a barrier membrane is placed over the graft material. This membrane serves to prevent the infiltration of non-osteogenic tissues, such as soft tissue, which could impede the process of bone regeneration. Over time, this allows the bone cells to proliferate and regenerate new bone in the targeted area, thereby creating a more stable foundation for future dental implants.

In contrast, the other options do not accurately represent the function of GBR. Tracking dental implants pertains to monitoring implant placement and integration, and it doesn't involve regenerative techniques. The process of GBR is distinct from orthodontics, as it primarily targets issues related to bone volume rather than tooth alignment. While tissue engineering can be involved in various aspects of dental procedures, GBR specifically focuses on bone regeneration, not the gums.
