Active clinical trials for "Alveolar Bone Loss"

This study evaluates the effect of citric acid demineralization in autogenous bone blocks consolidation. Half of participants will receive citric acid treatment at the bone block and recipient site. Other half will receive no demineralization treatment.

This study was designed as a multicentric prospective clinical trial to assess the clinical, biological and patient's perceived success of new wedge-shaped dental implants inserted in narrow ridges.

The purpose of this pilot study is to conduct a interventional prospective clinical trial to evaluate the efficacy of three different xenografts for ridge preservation by comparing the quality of newly formed bone using histomorphometric and micro CT analysis.The three xenograft materials under investigation are Bio-Oss® (bovine derived xenograft), Equimatrix® (equine derived xenograft), and Endobon® (bovine derived xenograft). There are no prospective studies comparing the effectiveness of these three materials, Bio-Oss®, Endobon® and Equimatrix®, when placed in extraction sockets. Participants will be recruited from patients in the TUSDM clinics that require extraction of single rooted non-molar tooth and are treatment planned to receive dental implants in the future. Participants will be randomized to receive one of the three xenograft materials after tooth extraction. The percentage of newly formed bone and bone density will be compared between the three materials 4-6 months after ridge preservation.

This study aims to verify the effectiveness of Trafermin (recombinant human basic fibroblast growth factor) in stimulating regeneration of periodontal tissue lost by periodontitis and to evaluate the safety of such stimulation.

The primary outcome of periodontal reconstructive therapy is to regenerate all tissues of the periodontium including a functional periodontal ligament, alveolar bone and cementum. A number of treatment modalities including the use of bone grafts, guided tissue regeneration (GTR), and the addition of biological agents have been used with large heterogeneity in the clinical and histological outcomes. The rationale of using a filling material when treating unfavorable and large intrabony defects (IBDs) with membranes or biological agents consists of sustaining the overlying soft tissues in the presence of a non-contained defect's architecture, at the same time enhancing the stability of coagulum; and facilitating the proliferation of mesenchymal progenitor cells. Among bone grafts available, anorganic bone bone (ABB) have been widely used in periodontics for the treatment of IBDs In recent years, the increasing understanding of the role of growth factors (GFs) in the wound healing process suggested the use of these biological agents in the regenerative treatment of periodontal bony defects. Noninferiority trials are designed to demonstrate that the effect of a new treatment is adequately similar to an active control by more than a specified margin The aim of this study is to verify if the combined use of PRF (Platelet Rich Fibrin) and ABB in the management of IBDs may be a treatment modality that is clinically "not inferior" compared to the membrane + ABB one, since the combined periodontal regenerative technique has been already tested in literature as a "gold standard" periodontal regenerative technique.

The effect of leucocyte- and platelet-rich fibrin (L-PRF) for enhancing the healing after dental extractions is still a matter of debate. The available literature suggests that L-PRF performs positive effect to improve alveolar preservation resulting in less bone resorption on extraction sockets. L-PRF is a second generation of platelet concentrate produced without biochemical blood manipulation. L-PRF is composed by three key parameters: first, the presence of platelets; second, the presence of leucocytes; third, the density and complex organization of the fibrin matrix architecture produced by a natural polymerization process. The theory is that this key parameters acts to produce a faster bone healing.

The aim of the present study is to evaluate the effectiveness of different alveolar preservation procedures performed at the time of extraction of the first or second upper molar in avoiding a maxillary sinus elevation or at least limiting the size, to allow the insertion of dental implants. The residual bone height will be radiographically evaluated on the sinus sinus floor at the time of extraction and after 6 months by comparing the cases where alveolar preservation is performed using a nanocrystalline synthetic hydroxyapatite graft (group A) with cases where the procedure of alveolar preservation is performed using bovine collagen sponge (group B).

The aim of this study is to evaluate the additional effect of antimicrobial photodynamic therapy regeneration treatment of mandibular furcation lesions when associated to bovine bone and porcine collagen membrane.

This study is being performed to compare different methods of visualization during routine gum surgery. The gum surgery is standard of care. This study will compare the use of a small camera (videoscope) in conjunction with magnification glasses during surgery vs. surgery only using magnification glasses. Both methods are routinely used and are standard of care methods of visualization. The small camera (videoscope) is a device which allows us to see the area under high magnification and projects live video feed on a computer screen. The study is a split-mouth design pilot study. The patients are only receiving treatment that was previously diagnosed prior to entering the study. The treatment performed is standard treatment that fits in the routine standard of care. No interventional treatment is being performed. The only difference is the method of visualization/observation by the practitioner used during the surgical procedure. One side of the mouth will be treated with just loupes while the other side of the mouth will be treated with loupes and the videoscope.

Patients with long span, narrow edentulous ridge in the posterior mandible underwent piezotomed ridge splitting and osseodensification with simultaneous implant placement.
