An Overview of Bone Grafting
Over time, the jawbone associated with missing teeth undergoes atrophy and is reabsorbed, resulting in insufficient quality and quantity of bone for dental implant placement. As a result, many patients may not qualify for dental implants in these situations.
Bone grafting in Little Rock provides the opportunity to replace missing bone and promote new bone growth in the affected area. This procedure not only enables the placement of implants with the appropriate length and width but also helps restore both functionality and aesthetic appearance.
Different Types of Bone Grafts
Autogenous Bone Grafts:
Autogenous bone grafts, or autografts, are derived from your own bone, typically harvested from areas such as the chin, jaw, lower leg, hip, or skull. One of the main advantages of autogenous grafts is that they consist of living bone, which contains cellular elements that promote bone growth.
However, a significant drawback is that obtaining an autograft requires a second surgical procedure to collect bone from another part of the body. Depending on your specific condition, this additional surgery may not be advisable.
Allogenic Bone:
Allogenic bone, or allograft, is harvested from a cadaver and then processed through a freeze-drying method that removes moisture via a vacuum. Unlike autogenous bone, allogenic bone cannot generate new bone independently. Instead, it acts as a framework or scaffold, allowing bone from the surrounding area to grow and fill the defect or void.
Xenogenic Bone Grafts:
Xenogenic bone is obtained from non-living bone of another species, typically cows. This bone is processed at high temperatures to eliminate the risks of immune rejection and contamination. Like allogenic grafts, xenogenic grafts serve as a scaffold for surrounding bone to grow into and fill any voids.
Both allogenic and xenogenic grafts offer the benefit of not requiring a second surgical procedure to harvest your own bone, as is necessary with autografts. However, because these options lack the bone-forming capabilities of autografts, bone regeneration may take longer and have less predictable outcomes.
