Regarding the blood studies, several in­ vestigators . have reported higher than normal values for total calcium, total cholesterol, uric acid, sugar and phos­ phatase (in gingival blood) in various percentages of their cases. Lower than normal values have been reported for vitamin C, erythrocyte count and carbon dioxide combining power. Other workers have failed to confirm the findings for cal...

Aim: Iliac crest (IC) is the most common source of bone for alveolar cleft repair, as it allows harvesting a large amount cancellous with high rate favorable outcomes. Its drawback donor-site morbidity. We propose new technique grafting using vomerine (VB), which, through grafting, reconstructs alveolus VB and simultaneously corrects nasal septum deviation. Method: performed 18 reconstructions ...

PURPOSE This study aimed at evaluating the bacterial colonization in dental implants inserted in the crestal or supracrestal position and correlated it to radiographic bone measurements. METHODS Thirty-five implants with regular platform in nine patients (mean age 62.4±11.2 years) were inserted either at the bone crest level (control group) or at a suprecrestal level (test group). Radiographi...

The aim of the present cross-sectional investigation was to evaluate percentage of bone loss in patients who had been one year under periodontal maintenance at the Department of Periodontology, Faculty of Dentistry, University of São Paulo by radiographic analysis. Complete sets of periapical radiographs provided data regarding percentage of alveolar bone loss, which was correlated with arches,...

This study aimed to evaluate the stress distribution and mechanical behavior of miniplate designs skeletal anchorage for treatment anterior open bite in adult patients. A complete hemimaxilla, teeth, brackets, transpalatal bar, three miniplates were virtually modeled. I-, Y-, T-shaped installed area alveolar zygomatic crest. The assembly was constricted intrusive forces (2, 4, 6 N) applied maxi...

the purpose of this study was to determine the influence of platform switching on stress distribution of two different implant systems using three-dimensional (3d) finite element models.six 3d finite element models were created to replicate two different implant systems with peri-implant bone tissue, in which six different implant-abutment configurations were represented: model xive-a: 3.8-mm-d...

INTRODUCTION Traditional Caldwell-Luc approach needs modifications for odontogenic cysts intruding into the maxillary sinus, to preserve sinus mucosa and bony contour. Recently, digital technology has been widely applied to the field of maxillofacial surgery, guiding the surgical plan and improving its accuracy. OBJECTIVE This study attempted to present and evaluate the functional surgery of ...

purposes: the aim of this study was to evaluate the intra and inter-examiner reliability and reproducibility of linear measurements in cone-beam tomography (cbct) images taken by calibrated radiologists and periodontists. materials and methods: the alveolar ridge dimensions in selected cbct images were measured by two calibrated radiologists and two periodontists. intra and inter-examiner relia...

Alveolar cleft repair is a debate topic in cleft lip and palate treatment.The aim of this article is to analyze the outcomes and the advantages of the autologous bone grafting performed during the period between 1981 and 2006. In our plastic surgery unit, 468 patients with alveolar clefts have been treated. According to our protocol, the timing for the closure of the alveolar cleft ranged from ...
