Nanoscale ridge aperture antennas have been shown to have high transmission efficiency and confined nanoscale radiation in the near field region compared with regularly-shaped apertures. The radiation enhancement is attributed to the fundamental electric-magnetic field propagating in the TE(10) mode concentrated in the gap between the ridges. This paper reports experimental demonstration of fie...

Alveoloplasty or alveolectomy is the surgical removal of a portion of the alveolar process. When multiple extractions are performed, the contours of the alveolar ridge should be considered in the light of future prosthetic needs. The ideal ridge is U shaped. Natural resorption will contour the ridges, occasionally unevenly, but a longer period of time is required, and the patient may experience...

The aim of this study was to use photoelastic models to analyze the distribution of stress caused by the incidence of loads on a mandibular distal extension removable partial denture, both on the abutment teeth and on differently shaped residual ridges: distal ascending, descending-ascending, horizontal and distal descending. The best type of retainer and location of the rest on the last abutme...

Background Dermatoglyphics could assist in the diagnosis of congenital abnormalities. The aim of this study was to identify the dermatoglyphic patterns (finger print pattern type, total ridge count of each finger, a-b ridge count, and articulotrochanteric distance [ATD angles]) in the parents of cystic fibrosis children. Materials and Methods We recruited 75 parents of children with cystic fibr...

Residual ridge resorption is a chronic, progressive, irreversible and cumulative disease. Stability defined as resistance to horizontal displacement of prosthesis. Providing stable lower denture has been challenging for dentists. This article outlines the management mandibular with dynamic impression technique. complete dentures challenged dentists patients alike. Dynamic technique clinically s...

The aim of the study was to investigate the clinical-anatomical peculiarities of edentulous mandibular dental segments (eMDS), situated in the posterior mandible, as well as to estimate the possibility of dental implantation for every clinical-anatomical eMDS type. One hundred and ninety-eight patients were examined, 88 male and 110 female. Orthopantomography, computer tomography, clinical exam...

The chelonian carapace is composed of dorsolaterally expanded ribs; an evolutionary change in the rib-patterning program is assumed to be related to this novelty. Turtle embryos exhibit a longitudinal ridge called the carapacial ridge (CR) on the flank, and its histological resemblance to the apical ectodermal ridge of the limb bud implies its inductive activity in the unique patterning of the ...

The effects of alcohol use on Pine Ridge are epidemic and have had a devastating impact on the current status of the residents. The historic effect of u.s. colonial relations with the Lakota has engendered a system of dependency, making the transition from an independent trading economy to capitalism difficult. This paper is an attempt to investigate the current life of Pine Ridge residents and...

background & aim: dental implants should be surrounded with at least 1mm bone. assessing ridge width is an important part to achieve this goal. the use of ridge mapping to assess bone levels available avoids some of the problems associated with ct-scanning. the aim of this study was to assess the accuracy of ridge-mapping compared to ct-scan in determination of bony ridge widths. methods & mate...
