Article Abstract
Autogenous tooth graft is an innovative and ingenious technique that employs a stepwise approach and utilizes human teeth as an autogenous source of bone graft. The structure of teeth closely resembles bone, both physically and biochemically, and can be efficiently used for the process as it depicts properties of osteoinduction and osteoconduction. Autogenous tooth bone has characteristics similar to bone grafts in terms of healing potential, physical properties, and clinical outcome. Autogenous tooth graft has shown reasonable promise as a graft material for the regeneration of maxillary and mandibular defects. Autogenous tooth bone graft finds its principal application in sinus and ridge augmentations and for socket preservation before implant placement. Additionally, it can be used successfully for alveolar cleft patients and patients with limited periodontal defects. The overall complication rates reported for autogenous tooth grafts are comparable to other graft sources. However, although long-term results are still underway, it is still recommended as a grafting option for limited defects in the cranio-facial region.
Hard and soft tissue remodelling after tooth extraction may result in a concave profile at the subsequent edentulous ridge. This defect may result in a sub-optimal aesthetic transition zone between the soft tissue and the pontic, which may appear to sit on the ridge, rather than emanating from within the ridge, as would a natural tooth. To optimise aesthetics, pontic site augmentation (PSA) (increasing the volume at the pontic site) and pontic site development (PSD) (remodelling the tissue at the pontic site) may provide a solution.
The study aimed to evaluate the effectiveness of autogenous bone grafts used before dental implant placement through long-term analysis using 3D modeling.
Nine patients participated, with evaluations occurring at three key time points: before grafting, after grafting, and post-implant placement, using digital scans of dental casts.
The results showed accurate superimposition of the casts, but indicated a significant decrease in the volume of the anterior maxilla, with reductions ranging from 14% to 38% after implant placement.
Generalized severe periodontitis, with the potential for additional tooth loss, is one of the most common forms of periodontitis today. Early diagnosis and treatment approaches are of utmost importance. Therapeutic measures must be well thought out and follow a strict sequence.
: The loss of teeth in the posterior maxillary region often leads to significant alveolar bone resorption and maxillary sinus pneumatization, complicating dental implant placement. Maxillary sinus grafting, typically using autogenous bone, is a common solution. However, autogenous bone grafts require additional surgical procedures, leading to increased morbidity.
The goal of mucogingival surgery or periodontal plastic surgery is to preserve gingiva, remove aberrant frenum or muscle attachments, increase vestibular depth, and correct the denuded root surface. Recession coverage is indeed a challenging technique, whereas covering the exposed roots is not only important for aesthetic reasons but also for preventing further issues such as tooth sensitivity, root decay, and loss of supporting bone. A coronally advanced flap (CAF) is one of the most common procedures done for recession coverage because of the concept that the coronal advancement of a flap without tension to cover the exposed root surface or CAF with autogenous grafts results in bulk and improves the thickness of the gingival tissue, increasing the stability and aesthetics of the result.
