OBJECTIVE This study used con-beam computed tomography (CBCT) to investigate the prevalence and severity of alveolar bone loss in middle-aged (40-59 years) Chinese with chronic periodontitis. MATERIALS AND METHODS The study group comprised 145 dentate individuals aged 40 to 59 years residing in China who suffered from chronic periodontitis. CBCT and the application of NNT software were used t...

PURPOSE The aim of this study is to evaluate the buccal and lingual bone thickness in the anterior teeth and the relationship between bone thickness and the tissue biotype. METHODS Three male and two female human cadaver heads (mean age, 55.4 years) were used in this study. First, the biotype of periodontium was evaluated and categorized into a thick or a thin group. Next, full thickness refl...

The management of facial defects has rapidly changed in the last decade. Functional and esthetic requirements have steadily increased along with the refinements of surgery. In the case of advanced atrophy or jaw defects, extensive horizontal and vertical bone augmentation is often unavoidable to enable patients to be fitted with implants. Loss of vertical alveolar bone height is the most common...

The purpose of this study was to morphometrically evaluate the influence of different durations of ovariectomy-induced estrogen deficiency on alveolar bone loss associated with ligature-induced bone loss in rats. Sixty female Wistar rats were randomly assigned to ovariectomy (OVX test group) or sham operation (SHAM control group). The OVX and SHAM groups were each distributed into three subgrou...

AIM The aim of this report is to describe a significantly deficient case of alveolar bone that was managed by alveolar bone augmentation using a technique of distraction osteogensis and onlay bone grafting prior to dental implant placement. BACKGROUND Injury to the teeth and alveolar ridge of the maxillary anterior region can cause a severe alveolar ridge deficiency resulting in ridge atrophy...

Background: After tooth extraction, alveolar bone resorption occurs naturally, followed by remodeling. Alveolar formation is characterized an increase in density and expansion of the trabecular bone. Socket preservation using a combination Moringa oleifera leaf extract demineralized freeze-dried bovine xenograft (DFDBBX) expected to area trabeculae thus accelerate process formation. Purpose: Th...

In this study, a three-dimensional elastic-plastic dynamic finite element model is used to simulate the alveolar bone temperature rise during dental implant drilling. An experimental setup was designed to verify the feasibility of the proposed dynamic finite element model. The peak bone temperature within the alveolar bone is investigated through both simulations and experiments. The results in...

The purpose of this study was to evaluate the clinical application of endosseous implants for management of grafted alveolar cleft. Four patients (1 male and 3 female; mean age 26.6 years; age ranging from 21.5 to 30.4 years at first implant surgery) with unilateral cleft lip and palate were evaluated. All patients received autogenous particulate cancellous bone and marrow graft (PCBM) to close...

There is evidence that the lack of metabolic control of obese patients may accelerate periodontitis. The aim of this study was to evaluate radiographically the effect of cafeteria-diet-induced obesity on alveolar bone loss in rats subjected to periodontal disease. Twenty male Wistar rats were randomly divided into four groups: 1) control group, 2) control and ligature group; 3) cafeteria group;...
