Filter by:Maintaining the general health and well-being of patients is the main goal of dental therapy. However, tooth extraction is indicated when teeth cannot be maintained in a status compatible with health, adequate esthetics, function, and/or for strategic reasons. A variable degree of alveolar ridge atrophy related to bone resorption is initiated immediately after removal of a tooth due to the local physiologic remodeling and the inflammatory response. Ridge resorption is more accentuated in the horizontal dimension, followed by the vertical mid-facial and vertical mid-lingual in non-molar and molar teeth. Among local periodontal phenotypic characteristics, facial bone thickness at the time of tooth extraction seems to be strongly associated with the extent of alveolar bone resorption. Dental implants have increased in popularity due to their unique ability to replace teeth. During the planning phase of implant therapy, one of the main parameters assessed is the amount of residual alveolar ridge. Therefore, when tooth replacement therapy via dental implant is considered, adequate management of the site is critical to predictably preserve or reconstruct the architecture of the alveolar ridge, particularly in the anterior aesthetic zone, where its structure play a crucial role in the maintenance of function, health and esthetics. Generally, with appropriate treatment planning and execution, the adequate primary mechanical stability of the dental implant is achieved. However, bone and/or soft tissue augmentation procedures could be needed for the adequate management of deficient edentulous ridges at the time of implant placement, and these types of treatments could considerably increase the risk of morbidity, treatment expenses, and length of treatment time. Nevertheless, Implant placement with additional bone contour augmentation therapies have shown their effectiveness in the short-, mid- and long-term in contemporary dental practice. However, to the present date, there is no information available in the literature regarding patient-reported outcome measures in patients that received tooth replacement therapy via dental implants with additional contour bone augmentation in the short-, mid- and long-term.
The purpose of this prospective trial is to investigate ABM/P-15 bone graft versus traditional bone graft in patients undergoing surgery for Adult Spinal Deformity (ASD) in order to provide better clinical results through faster bone healing, no additional surgeries, fewer complications and thereby increase health-related quality of life. Main hypotheses: 1. The use of ABM/P-15 bone graft is superior to traditional bone graft treatment regarding the incidence of additional surgeries following index surgery for ASD Secondary hypotheses: 2. The investigators expect non-inferiority in patient reported outcome measures in the ABM/P-15 bone graft group compared to the control group 3. The investigators expect non-inferiority in the postoperative fusion rates (bone healing) evaluated on CT scans in the ABM/P-15 bone graft group compared to the control group 4. The investigators expect non-inferiority in postoperative incidence of asymptomatic pseudarthrosis in the ABM/P-15 bone graft group compared to the control group 5. The investigators expect non-inferiority in perioperative complications in ABM/P-15 bone graft group compared to the control group 6. The investigators expect the use of ABM/P-15 bone graft to be cost-efficient compared to the traditional treatment in the control group
