Osseointegration is also defined as: "the formation of a direct interface between an implant and bone, without intervening soft tissue". [1]An osseointegrated implant is a type of implant defined as "an endosteal implant containing pores into which osteoblasts and supporting connective tissue can migrate". [2]
Bone grafting is a surgical procedure that replaces missing bone in order to repair bone fractures that are extremely complex, pose a significant health risk to the patient, or fail to heal properly. Some small or acute fractures can be cured without bone grafting, but the risk is greater for large fractures like compound fractures.
Many surgical approaches are used in the treatment of advanced periodontitis, including open flap debridement and osseous surgery, as well as guided tissue regeneration and bone grafting. The goal of periodontal surgery is access for definitive calculus removal and surgical management of bony irregularities which have resulted from the disease ...
Demineralized freeze dried bone allograft, referred to as DFDBA, is a bone graft material known for its de novo bone formation properties. [1] It is used extensively in bone grafting of alveolar bone in oral and periodontal surgery.
Autologous bone graft is the "gold standard" treatment and possesses osteogenic, osteoinductive, and osteoconductive properties, although only a limited sample can be taken and there is a high risk of side effects. [11] Bone graft substitutes. Inorganic bone substitutes may be used to complement or replace autologous bone grafting.
In orthopaedic medicine, a bone graft can be sourced from a patient's own bone in order to fill space and produce an osteogenic response in a bone defect. However, due to the donor-site morbidity associated with autograft, other methods such as bone allograft and bone morphogenetic proteins and synthetic graft materials are often used as alternatives.
The screw-root form design is directly threaded into bone and has macroscopic retentive elements for initial bone fixation. A direct connection between bone and the implant provides high initial stability. Over time, screw-root form designs experience bone resorption and "bone modelling and remodelling at the bone to implant interface". [9]
Occlusal trauma; Secondary occlusal trauma on X-ray film displays two lone-standing mandibular teeth, the lower left first premolar and canine. As the remnants of a once full complement of 16 lower teeth, these two teeth have been alone in opposing the forces associated with mastication for some time, as can be evidenced by the widened PDL surrounding the premolar.
