View clinical trials related to Alveolar Bone Loss.
Filter by:The goal of this clinical trial is to compare in patients with atrophied anterior maxilla, bone augmentation techniques ( gold standard bone block and tent pole technique). The main question it aims to answer is : Does screw tent pole technique provides better bone gain than autogenous bone block in atrophied anterior maxilla? - primary objective to assess amount of bone gain - secondary objective assess bone quality Participants will be randomly divided into two groups study group ( tent pole technique) and control group ( bone block) - each group will be followed up monthly for soft tissue dehiscence and after 6 month to assess bone gain and bone quality and then implant placement.
Objective: The objective is to evaluate the dimensional changes of soft tissue and alveolar ridge after extraction of posterior elements with different clinical protocols of alveolar preservation.
Atrophied jaw is a condition where there is insufficient bone quantity to place root form implants. Several treatment plans are available for treating atrophied jaws, including subperiosteal implants. Subperiosteal implants were introduced in the last century. Poor clinical results led those implants to be progressively abandoned. Recently, several Authors suggested a revival of subperiosteal implants as an alternative to regenerative procedures.
Utilization of collagen vs PRF membrane over the graft following sinus lift procedure and before suturing
To compare the diagnostic accuracy of extra-oral x-rays with intra-oral x-rays, in contrast to clinically observed measurements, for the detection of calculus and bone loss of either the suprabony or infrabony types in patients undergoing periodontal surgery.
The aim of the research is to evaluate the clinical outcome of short dental implants, characterized by a new macro-structural design and inserted in the upper or lower jaw in patients with reduced bone volume. The clinical outcomes will be compared for different surface treatments of implant neck and those of prosthetic components.
The goal of this clinical trial is to test in height increment of alveolar bone and safety evaluation index. The main question it aims to answer are: • The safety and effectiveness of magnesium calcium silicate three-dimensional alveolar bone repair unit in the repair of periodontal bone defects Participants will be treated through Guided Bone Regeneration operation with calcium magnesium silicate three-dimensional alveolar bone repair unit.
Aim of the present investigation will be to evaluate the efficacy and safety of a granulate of rhBMP-2- loaded bovine bone mineral (rhBMP-2-BBM) as alveolar bone regeneration procedure following tooth extraction. Forty (40) patients (both sex; age 18 years and older) requiring extraction of one (1) hopeless tooth (incisor, canine or premolar with loss of bone height of 5 mm or more in buccal alveolar wall), followed by alveolar bone regeneration (ABR) and placement of an endosteal implant will be enrolled into the study. After exodontia, participants will be randomized and divided into two groups: in Experimental Group the socket will be grafted with rhBMP-2-BBM granules (1.0-0.25 mm); in Control Group the sockets will be grafted with Bio-Oss granules (1.0-0.25 mm) and covered with porcine collagen barrier membrane (Bio-Gide). The end of the study will be fixed at the implantation surgery, seventeen (17) weeks after exodontia an ABR. Cone beam computed tomography (CBCT) scans will be made, immediately after (0), and sixteen (16) weeks after exodontia an ABR and the gain in alveolar bone height will be estimated and used as the primary outcome for comparison of both groups. As secondary efficacy outcomes the change in alveolar bone width estimated from the CBCT scans; initial (0) and at seventeenth (17th) week after tooth extraction; the change in dental arch dimensions estimated from tridimensional models obtained from intraoral scans at one week before (-1) and sixteen (16) weeks exodontia an ABR; and the amounts of new bone, remnant material and connective tissue histomorphometrically measured in a bone biopsy collected during the implantation surgery at seventeenth (17th) week, will be considered. Healing of gingival tissues at first (1st) and second (2nd) week and incidence of adverse reactions at first (1st), second (2nd) and sixteenth (16th) week, are used as secondary safety outcomes.
With alveolar ridge preservation (ARP) ridge resorption following extraction may be reduced. Several materials and techniques have been advocated for ARP. The aim of our randomised clinical trial is to evaluate the efficacy of extraction side development technique (XSD) and autogenous tooth bone graft (ATB) for ARP.
The primary aim of the present study is to compare the Sub-periosteal Peri-implant Augmented Layer (SPAL) technique and soft tissue augmentation (STA), performed simultaneously to implant placement, in terms of (i) implant survival rate and (ii) health/disease condition of the peri-implant tissues at 6 and 12 months following implant loading. The secondary aim of the project will be to compare the SPAL technique and STA in terms of intra- and post-operative morbidity. The study is designed as a single-blind, parallel-arm, randomized clinical trial. Patients will be recruited and treated at the Operative Unit of Dentistry, Azienda Unità Sanitaria Locale (A.U.S.L.) of Ferrara, Italy, and one University center (Research Centre for the Study of Periodontal and Peri-implant Diseases, University of Ferrara, Italy). Each patient will contribute the study with one sextant ("experimental sextant"). Each eligible patient will be randomly assigned to receive SPAL technique or STA according to a computer-generated randomization list. Surgical procedures will be performed by experienced periodontal and implant surgeons. Two calibrated, blinded examiners will take care of the assessment of clinical and radiographic parameters, Case Report Form (CRF) filling, as well as data extraction from CRFs for the preparation of the study database. The proportion of patients free from peri-implantitis at 12 months following loading will be the primary outcome variable of the study. The proportion of patients with complete resolution of the bone dehiscence (BD), dimensional variations and 12-months characteristics of BD, and patient-reported outcome measures will be the secondary outcomes. The design will test two hypotheses, with a non-inferiority trial in terms of primary outcome and a superiority trial in terms of secondary outcomes.
