A 60-year-old Tunisian male, treated for an axial spondyloarthritis with indometacin (100 mg per day), consulted for a new 4-month history of inflammatory neck pain. The neurologic exam was normal. Radiographs of his neck showed a vertical atlantoaxial subluxation. MRI did not find any neurological suffering. Atlantoaxial subluxation is an uncommon and potentially fatal complication of spondylo...

OBJECTIVES This study aimed to evaluate the vertical discrepancy of implant-supported crown structures constructed with vacuum-casting and Direct Metal Laser Sintering (DMLS) technologies, and luted with different cement types. STUDY DESIGN Crown copings were fabricated using: (1) direct metal laser sintered Co-Cr (LS); (2) vacuum-cast Co-Cr (CC); and (3) vacuum-cast Ti (CT). Frameworks were ...

nowadays, due to recent developments and researches in dental science, it is possible to preserve and restore previously extracted cases such as teeth with extensive caries, fractured or less appropriate cases for crown coverage as well as teeth with external perforation caused by restorative pins. in order to restore the teeth with preservation of periodontium, we should know thoroughly physio...

Three new species of the genus Conophyma Zobovsky, 1898 from Xinjiang, West China are described in this paper. The Conophyma xiai sp. nov. is similar to C. olive Huang, 2006, but differs from latter by: vertical diameter of eyes 1.7 times subocular furrow, minimum width of interspace of mesosternum 1.6 times length, hind tibia yellow and furculae smaller. The new species Conophyma nigrifemora s...

The purpose was to quantify the setup margin for pediatric patients with neuro-blastoma using cone beam CT imaging (CBCT) and ultrasound localization. Ten patients, with a median age of 4.3 years (1.8 to 7.9) underwent daily pretreatment localization CBCT and every other day post-treatment CBCT to calculate interfractional and intrafraction movement. Localization was based on CBCT to treatment ...

Background information The role of leg length discrepancy (LLD) has been implicated in certain types of scoliosis [1]. Scoliotic LLD has been suggested as a result of rotation of the innominate bones [2]. However, the role of innominate vertical lengths (IVLs) as a predisposing factor for scoliosis is not clear. The reliability of radiographic measurements may reveal whether IVL can be used as ...

A 40 km-resolution ice-ocean model of the Bering Sea is used to investigate the effects of ocean circulation and vertical convection on the seasonal and interannual ice extent variations in the Bering Sea. The model is driven with daily time-varying atmospheric forcing from 1981-83. A series of sensitivity studies is carried out to examine the effects of the vertical diffusion and precipitation...

Angle Class III malocclusion is characterized by anteroposterior dental discrepancy which might be associated or not with skeletal changes. Class III molar relationship is associated with vertical or lingually tipped mandibular incisors and a usually concave profile. These characteristics seriously affect facial esthetics and most frequently are the reason why patients seek orthodontic treatmen...

PURPOSE A number of provisional restorative materials exist on the market. This study tested marginal fit and color stability of three provisional restorative materials and a control. MATERIALS AND METHODS Two auto-cure materials, Protemp Garant and Integrity, and one dual-cure material, Luxatemp Solar, were tested against SNAP, a polyethyl methacrylate control. A maxillary right central inci...
