The purpose of this study is to evaluate the dimensional changes that occur in the alveolar ridge after minimally traumatic tooth extraction by means of computed tomography (CT), with special focus on the portion of bone supporting the gingival zenith. Twenty subjects with indication for singlerooted tooth extraction and preserved alveolar walls were selected for this study. After a minimally t...

An implant-abutment interface at the alveolar bone crest is associated with sustained peri-implant inflammation; however, whether magnitude of inflammation is proportionally dependent upon interface position remains unknown. This study compared the distribution and density of inflammatory cells surrounding implants with a supracrestal, crestal, or subcrestal implant-abutment interface. All impl...

Abstract Background Bisphosphonates‎ inhibit osteoclasts, prevent bone resorption and decrease bone turnover. This study examined radiography finding in bisphosphonate-associated osteonecrosis of jaws. Materials and Methods This is a retrospective series of 12 clinically diagnosed patients between 7 to 21 year old (average 13 years). They required emergency dental conditions requiring mana...

OBJECTIVES Localization of the mandibular canal (MC) and measurement of the height and width of the available alveolar bone at the proposed implant site in the posterior segment of the mandible using cone-beam computed tomography (CBCT) in patients with a single missing tooth. MATERIALS AND METHODS A cross-sectional study was performed where CBCT scans of the patients with a single missing to...

Purpose. The aim of this study was to verify the prevalence of alveolar bone loss in Brazilian adolescents through the interproximal X-rays analysis. Methods. Bilateral and standardized interproximal (bitewing) X-rays were performed in 15-year-old adolescents (n = 326), and the processing of films and measurements of alveolar bone levels were accomplished by a single examiner. A distance betwee...

The aim of this study was to evaluate the effects of nonsurgical periodontal treatment on alveolar bone density (ABD) and bone height (BH) using direct digital radiography. Nineteen patients (mean age: 36 ± 7.3 years) with generalized chronic periodontitis were examined at baseline, 90 (90 AT) and 180 (180 AT) days after nonsurgical periodontal therapy. Radiographs were taken from two sites wit...

BACKGROUND The aim of this study was to assess the influence of ridge morphology on the amount of horizontal bone augmentation achieved with the sandwich bone augmentation (SBA) technique in the reconstruction of buccal dehiscence defects on dental implants. METHODS Cone beam computed tomography (CBCT) was used to assess bone width changes in 26 patients who participated in a randomized contr...

Following extraction of the teeth, the remaining socket heals from the apex toward the crest. When nothing is placed into the socket at the time of tooth removal, the infiltration of soft tissue at the crest often results in facial and crestal bone loss. Many literatures consider socket preservation as a necessity for further esthetic considerations in the pre-prosthetic and corrective procedur...

The purpose of this study was to determine the prevalence of abnormal alveolar bone in children and adolescents. Radiographs of 1026 patients were classified as showing negative, questionable, or positive evidence of abnormal alveolar bone resorption, based on criteria that included the distance between the cementoenamel junction to the alveolar bone and the integrity of the alveolar crest. App...
