Dental Implant Literature Review
Rehabilitation of edentulous patients with a dental implant or multiple dental implants can be limited because of the lack of sufficient bone volume in order to gain dental implant stability and gain good prognosis of future fixed restorations. Several grafting materials and techniques have been used with varying clinical outcomes. According to the literature, the gold standard is still autogenous bone grafts even though graft resorption is often encountered during healing. In order to reach a successful clinical outcome with dental implant integration and survival of implants, newly grafted bone have to be incorporated in the recipient site.
Several publications have reported about different augmentation techniques using autogenous bone graft as block bones as well as particulate bone. It is believed that blocks of bone are more structurally stable and therefore less prone to resorb, but on the other hand the revascularization process takes longer time compared with a mix of blood and bone particles. There is a tendency of less resorption on the particulate side initially. However, in a study published in Clinical Implant Dentistry and Related Research showed that there is no significant difference in the extent of resorption between block bone grafts or particulate bone grafts over a 5-year period. Also, there was no difference in dental implant stability when comparing different grafting techniques.
Dental Implant Case Presentation
The current patient presented with a hopeless fixed partial bridge due to a root fracture. The hopeless teeth were extracted and a particulate bone graft technique was utilized to gain proper bone width and height for subsequent dental implant placement. Straumann tissue level dental implants were surgically placed and restored with porcelain crowns. Total treatment time was approximately 8 months. Utilization of dental implants have been the best way for my patients to regain proper function when teeth must be extracted.
