Filter by:The aim of the study is to evaluate the crestal bone loss developed around short dental implants after using screw retained Hybrid ceramic crowns when compare to screw retained Lithium Di silicate based ceramic crowns.
The aim of this study will be to compare the long-term outcomes of sandblasted and acid-etched (SLA) implants in patients previously treated for periodontitis and in periodontally healthy patients (PHP) after a follow-up of at least 20-years.
This clinical trial aims to investigate the efficacy of freeze-dried bovine hydroxyapatite/secretome composite application for the management of long bone defects and other bone healing disorders in the lower extremities.
This observational study aims to assess kidney function through direct glomerular filtration rate (GFR) using iohexol clearance, compared to estimated GFR based on creatinine and cystatin C equations. Kidney function will also be evaluated through renal fibrosis biomarkers. Kidney function will be correlated to body composition, muscle turnover biomarkers, and bone micro-architecture.
This study is seeking to evaluate that platelet-derived growth factor-BB (PDGF-BB) is a proven wound healing and osteogenic protein that plays a critical role in wound healing and previous research has demonstrated a non-linear response where higher dosages produced less effect. As Platelet Rich Fibrin (PRF) contains numerous platelets, it contains PDGF-BB, but at levels lower than in the commercially available product and with inter-individual variation, GEM21S. To achieve both ideal handling and achieve ideal levels of PDGF-BB, there is a rationale to add GEM 21S recombinant human platelet-derived growth factor-BB (rhPDGF) to a bone graft prior to making "sticky bone".
This study will compare two techniques to achieve increase in ridge dimensions as a preparation for dental implants using a resorbable barrier membrane and bone particulate allogenic graft hydrated with saline or a growth factor called Recombinant Human Platelet-Derived Growth Factor (rhPDGF).
this study was to compare the bone height changes around three implant telescopic, locator, and ball retained mandibular overdentures. radiographic changes in peri-implant tissue in three groups were evaluated
The purpose of this research study is to see whether receiving a bisphosphonate medication called risedronate can reduce bone and muscle loss following bariatric surgery. Participation will involve up to 6 study visits and last about 1 year. Risedronate is a medication that prevents bone breakdown and has been approved by the US Food and Drug Administration (FDA) for the prevention and treatment of osteoporosis in older men and women. However, risedronate has not been approved for the prevention of bone and muscle loss following vertical sleeve gastrectomy. Participation in this study will involve completing two visits before beginning the intervention. Participants who qualify will be scheduled to begin the intervention program which will involve taking 6 monthly doses of a risedronate or placebo pill. Participants will then receive monthly contacts by study staff during this time to remind participants to take the intervention pill and ask about any adverse events. After the completion of intervention period, participants will complete up to 4 follow up study visits at 6 months (2 visits) and at 12 months (2 visits).
Masquelet's induced membrane technique is a two-stage reconstructive surgery for severe bone fractures commonly used by military orthopedists. The particularity of this technique relies on the synthesis of a biological membrane induced by the transient implantation of a surgical cement (= 1st stage surgery). The presence of the induced membrane in the reconstruction space defines a microenvironment or "biological chamber" favourable to osteogenesis, positively influencing the repair of the lesion after implantation of an autologous bone graft (= 2nd stage of surgery). In view of the excellent clinical results obtained with this procedure, the Masquelet technique has gradually become a reference treatment in the field of orthopedic and trauma surgery. However, orthopedic surgeons sometimes observe failures in bone consolidation. To our knowledge, the role played by induced membrane in these therapeutic failures has never been studied.
When a dental extraction is performed, sequential cascade of events happens that lead to a modeling and remodeling of the area. This phenomenon leads to bone resorption and consequential volume loss atrophy. In literature several biomaterials (Autogenous, alloplastic, allografts and xenografts) were tested as alveolar fillers with the aim of controlling this physiologic event. Socket preservation is today a very widely spread dental technic to preserve the alveolar dimensions, that uses a wide range of biomaterials. Alloplastic materials have a fair evidence to work in several regenerative procedures in the oral and maxillofacial region. This pilot trial aims to characterize Histologic bone healing pattern in a human socket preservation model of 2/3 biphasic calcium sulfate cement matrix's and Hydroxyapatite (HA granules). Alterations in Volumetric alveolar socket changes in a socket preservation clinical model will also be studied.
