Active clinical trials for "Alveolar Bone Loss"

The study is a 3-arm, parallel-design, randomized, prospective clinical trial.designed to examine histologic wound healing following ridge preservation using cortical bone allograft, cancellous bone allograft, or a combination of both cortical and cancellous bone allograft. This entire protocol involves procedures that are standard care. All materials are FDA-approved materials being used in an FDA-approved manner. The test group subjects will have extraction sockets grafted with a combination of 50% cortical/50% cancellous FDBA. This test group will be compared to two active control groups - one using 100% cortical FDBA and the other using 100% cancellous FDBA. The null hypothesis is that there will be no significant difference in formation of new vital bone between treatment groups (primary outcome). Each subject will provide a single non-molar tooth site for study treatment. After tooth extraction, the graft material will be placed and covered by a non-resorbable membrane. Following 18-20 weeks of healing, the dental implant will be place, at which time a core of bone will be removed from the site as part of the preparation for the implant. The core biopsy will then be evaluated for the primary histologic outcome of % vital bone formation and secondary histologic outcome of % residual graft material.

Purpose: The proposed study will evaluate and compare the clinical response of using bioresorbable collagen membrane alone or defect debridement with erbium Laser irradiation in conjunction with bioresorbable collagen membrane in the treatment of Class II furcation defects in maxillary and mandibular teeth. The study will examine whether there is a superior regeneration potential when the laser energy is combined with membrane defect isolation. Procedure: The study will use 2 groups, a control group and a test group with 16 patients in each group, with severe chronic periodontitis having clinical or radiographic evidence of Class II furcation defects in the buccal or lingual of the mandibular molars or Class II furcation defects on the buccal of maxillary molars. 16 patients will serve as the control group and open flap debridement with bioresorbable collagen membrane will be the mode of treatment. Group 2: 16 patients will serve as the test group and will undergo open flap debridement in conjunction with Er, Cr: YSGG laser irradiation and a bioresorbable collagen membrane will be used.

The primary aims of this study are to compare the clinical and histologic results of bone regeneration with a cancellous block allograft versus MinerOss Cortico cancellous particulate allograft mixed with autogenous bone chips after 4 months of healing. Titanium reinforced hd-PTFE (Cytoplast) membrane GBR will be used to cover the bone grafts. Specific Aim 1: To compare the baseline to 4 month change in clinical ridge width and height. Specific Aim 2: To compare the histologic percent of vital and nonvital bone and trabecular space at 4 months. The primary outcome variable is the change in horizontal ridge width. The secondary outcomes are the change in ridge height and the percent histologic composition of the augmented site.

The hypothesis of this study is that there is a significant difference in bone maturation after sinus grafting determined by the distance from the buccal to the palatal wall of this cavity.

The present study is a human, prospective, randomised controlled clinical trial conducted to explore the outcome of a minimally invasive ridge augmentation technique with and without low level laser therapy. The trial is in accordance with the Consolidated Standards of Reporting Trials (CONSORT) criteria, 2010.

Completely or partially edentulous patients suffer from resorption of the alveolar bone, they always seek rehabilitation which becomes challenging. Alveolar ridge augmentation is widely done now to offer these patients functional and esthetic restoration. Many techniques have been proposed to obtain good results of ridge augmentation. Titanium Mesh (TiMe) is widely used, also digital and computer-guided surgery now plays an important role to improve the techniques and results in ridge augmentation procedures.

The aim of this study was to evaluate clinically and radiographically the splinted short implants' and single short implants' stability and bone condition before and after loading, in atrophic posterior mandibular alveolar ridges.

A prospective randomized controlled trial of 30 patients from the Faculty of Dentistry of the UFJF was conducted. It was included patients who presented indication of extraction of premolars, canines or incisors. All the thirty patients underwent dental extraction and were randomly divided into three groups according to the study methodology. Plaster casts and Cone-Beam Computed Tomography (CBCT) exams were performed for comparative analysis between sample groups and between study times ( imediate postoperative and four months later).

The present study is a human, prospective, parallel, randomised controlled clinical trial conducted to explore the efficacy of injectable PRF around dental implants. The trial is in accordance with the Consolidated Standards of Reporting Trials (CONSORT) criteria, 2010.

The purpose of this study is to evaluate the INFUSE® Bone Graft as an alternative to autograft for bone formation in the back of the mandible (lower jaw) prior to placing dental implants.
