The use of stem cells in dental implant site development
The placement of dental implants in a prosthetically ideal position is often challenged to any Dentist by the lack of sufficient alveolar bone. Therefore, augmentation of the insufficient bone volume prior to or at the time of implant placement is often required to attain a long-term function and esthetic result.
Alveolar ridge deficiencies may result from tooth extraction and subsequent resorption of bone, existing periodontitis, trauma, or developmental defects. Guided bone regeneration (GBR) is the term used to describe those procedures aiming at regenerating bone, via the use of barrier membranes, in areas with alveolar ridge deficiencies, thus allowing implant placement in an appropriate angulation. Evidence-based treatment results indicate that GBR for localized alveolar ridge deformities can effectively augment the ridge width (horizontal dimension) with new bone in the range from 1.1 mm to 5.7 mm. The average gain in ridge width is approximately 3.6 mm, with some variations noted depending on the surgical technique and materials used for the augmentation procedure.
