This article describes the use of three devices that replace the wax rims in the registration of the intermaxillary position and of the vertical dimension of occlusion in completely edentulous patients who have been treated with Brånemark implants. The devices consist of a mechanical "tooth" that can be adjusted in all three dimensions of space and of two plates that support the registration ma...

One of the key challenges of visual perception is to extract abstract models of 3D objects and object categories from visual measurements, which are affected by complex nuisance factors such as viewpoint, occlusion, motion, and deformations. Starting from the recent idea of viewpoint factorization, we propose a new approach that, given a large number of images of an object and no other supervis...

this study aimed at determining the chronic and acute effect of submaximal pedaling activity along with blood flow restriction on serum bdnf, tnf-α and bdnf/tnf-α ratio in active men. 24 physical education students at kharazmi university volunteered for the study. they were divided into three groups: pedaling with lower extremity vascular occlusion (n=8), pedaling without occlusion (n=8), and c...

It is generally assumed that children with posterior crossbites have abnormal mandibular movements; however, this assumption has not been clearly evaluated. The purpose of this investigation was to study the movements and the resting position of the mandible in 2 samples of 30 subjects, one aged 10 to 14 years with right posterior crossbite, the other aged 10 to 15 years with normal occlusion. ...

OBJECTIVE The aims of our study were to verify the validity of the T-Scan III system (Tekscan) as an objective occlusal evaluation tool, and to assess the differences between two occlusal indexes-the peer assessment rating (PAR) index and the American Board of Orthodontics objective grading system (OGS)-by comparing the scores derived from the T-Scan III system with the two occlusal indexes and...

BACKGROUND Subcutaneous mastectomy for female- to-male transsexuals is usually the first surgical pro- cedure in sexual reassignment. The main objective of subcutaneous mastectomy is to create an aesthetically pleasing male chest contour by removing all glandular tissue while minimizing chest wall scars. AIMS In this paper, we present our experience with subcutaneous mastectomy performed in f...

We report a case of successive bilateral retinal vein occlusion in a human immunodeficiency virus (HIV)-positive male with multicentric Castleman's disease treated successfully with a single injection of intravitreal bevacizumab. Castleman's disease should be a differential diagnosis of occlusive retinovascular disease and, occasionally, ocular manifestation can lead to systemic diagnosis.

retinal vein occlusion (rvo) is a common retinal vascular occlusive disorder and is associated with a variety of systemic risk factors. the aim of this study was to investigate whether the underlying diseases were evaluated and managed appropriately by ophthalmologists. we performed a study of 1344 patients with retinal vein occlusion (rvo). patients were evaluated with a questionnaire includin...

statement of the problem the aim of this study was to compare the treatment outcome of cl i malocclusion patients treated by two methods, including standard edgewise and mbt. materials and methods thirty subjects (23 boys and 7 girls) with an age range between 14‒19 years were included in each group. the patients had cl i malocclusion and were treated through non-ext strategy. pre- and post-tre...

A posterior cross-bite is defined as an abnormal bucco-lingual relationship between opposing molars, pre-molars or both in centric occlusion. Although it has been reported that patients with unilateral posterior cross-bite often show unique chewing patterns, the relationship between the form of cross-bite and masticatory jaw movement remains unclear in adult patients. The objective of this stud...
