OBJECTIVE To investigate the influence of location and preparation design on the survival and complication rate of metal-free polymer crowns within a prospective clinical study. METHODS After randomization, a total of 114 (68 posterior and 46 anterior) single crowns were prepared, either with a chamfer finishing line or with a shoulder combined with occlusal reduction of at least 1 mm. Build-...

conclusions generalized ligamentous laxity is an important predisposing factor for acute and chronic shoulder injuries in athletes. prescreening programs for beginners and rehabilitation shoulder programs for sports athletes at high risk are strongly recommended. results group a (with ligamentous laxity) consisted of 43 participants (36.4%) and group b (without ligamentous laxity) consisted of ...

New finds of well-preserved remains coiled nautiloids from lower Moscovian sediments (Kamenskaya Formation) the Donets Basin (eastern Ukraine) allowed to describe color pattern on conch surface species genera Parametacoceras, Metacoceras, Coelogasteroceras and Ephippioceras. The studied is represented by longitudinal light bands along ventrolateral shoulder (Parametacoceras Metacoceras), transv...

Fused Deposition Modeling (FDM) parts are typically subject to process-related rough or wavy surfaces, with stair-stepping effects whenever the parts produced have sloped or rounded part geometries; however, the level of optical quality frequently required demands that parts feature a smooth surface. In this paper, the results of a high-energy finishing process, which uses a disc finishing unit...

The objective of this study was to determine if dietary cation-anion balance (DCAB) affects the concentration of S that can be tolerated by growing and finishing cattle without adversely affecting performance. Angus cross and Bradford steers (n=114; average initial BW=252.8 kg) were blocked by BW and breed, and randomly assigned within a block to treatment. The design was a 3 × 2 factorial arra...

Three hundred six crossbred steers (703 ± 1 lb) were used to determine effects of adapting steers to a finishing diet using RAMP for 14 to 30 d on steer performance and carcass characteristics. RAMP treatments were compared to a traditional step-up procedure (CON) utilizing an initial concentration (DM-basis) of 32.5% steam-flaked corn (SFC), 45% alfalfa hay (ALF), 20% Sweet Bran, and 2.5% supp...

V899 Mon is an eruptive young star showing characteristics of both FUors and EXors. It reached a peak brightness in 2010, then briefly faded 2011, followed by second outburst. We conducted multi-filter optical photometric monitoring, as well near-infrared spectroscopic observations Mon. The light curves color-magnitude diagrams show that has been gradually fading after its outburst 2018, but sm...

We have investigated the mid-term outcome of total shoulder replacement using a keeled cemented glenoid component and a modern cementing technique with regard to the causes of failure and loosening of the components. Between 1997 and 2003 we performed 96 total shoulder replacements on 88 patients, 24 men and 64 women with a mean age of 69.7 years (31 to 82). The minimum follow-up was five years...

abstract a 2.5 year old girl is presented with both hands constriction bands leading to distal amputations and the rare deformity of shoulder duplication in the right side accompanying constriction skin marking over the affected shoulder. the cephalomedial scapula articulated with the clavicle and the caudolateral scapula articulated with humeral head. the most important physical finding which ...
