OBJECTIVES To investigate the prevalence, location, size and course of the anastomosis between the dental branch of the posterior superior alveolar artery (PSAA), known as alveolar antral artery (AAA), and the infraorbital artery (IOA). MATERIAL AND METHODS The first part of the study was performed on 30 maxillary sinuses deriving from 15 human cadaver heads. In order to visualize such anasto...

This study evaluated dental implant stability, vertical bone gain, density, and crestal loss using different sinus lift techniques (osteotomy, Densah burs, piezosurgery). A total of 21 patients were randomly divided into three groups: Group 1: treated a drill lift, 2: piezoelectric 3: an osteotome lift. The in all groups underwent grafting placement. An Osstell device was used to determine the ...

Dental implant survival requires the presence of peri-implant bone for complete and stable osseointegration. Grafted sinus lift procedures are predictable methods to augment deficient ridges, but may give rise complications, comorbidities, additional costs. Recent evidence showed positive outcomes graft-less technique. However, studies comparing outcome grafted still lacking. This study aims co...

Openand closed-loop control of vortex shedding in two-dimensional flow over a flat plate at high angles of attack is numerically investigated at a Reynolds number of 300. Unsteady actuation is modeled as a body force near the leading or trailing edge, and is directed either upstream or downstream. For moderate angles of attack, sinusoidal forcing at the natural shedding frequency results in pha...

BACKGROUND Osteotome sinus floor elevation is a less invasive approach to augment an insufficient alveolar bone at the posterior maxilla for dental implantation. However, this approach has some limitations due to the lack of sinus lift tools available for clinical use and the small transcrestal access to the maxillary sinus floor. We recently invented shape-memory Ni/Ti alloy wire containing tu...

INTRODUCTION The present study was undertaken to evaluate the anatomy of the maxillary sinus in relation to its position and the height of its septa, using cone beam computed tomography (CBCT). MATERIALS AND METHODS In this descriptive retrospective study, 300 CBCT images of maxillary sinuses of patients with posterior maxillary edentulism were evaluated. The maxillary sinus septa were evalua...

INTRODUCTION Dental implants have been associated with the occurrence of postoperative rhinosinusitis. In some patients, preoperative sinus lifting must be performed to increase the chances of successful implant placement. This retrospective study examines the relationship of dental implants after sinus lifting with the occurrence of postoperative rhinosinusitis. METHODS A total of 268 dental...

Purpose Analyzing different patterns of maxillary sinus septa in cone-beam computed tomography (CBCT) images and predicting maxillary sinus membrane perforations. Materials and Methods In this cross-sectional study, CBCT images of 222 patients ranging from 20 to 81 years old were evaluated. One hundred fifty-two patients (93 females and 59 males) who had maxillary sinus septa in axial views w...

introduction: pilonidal sinus is a common disease in sacrococcygeal area, which mostly caught young people and cause disability, which needs complete rest at home and taking off from work. although the surgical treatment of this problem goes back to the last century, still optimal treatment is a controversy. recent studies have raised different surgical approaches, so that there is no general a...
