PURPOSE A die stone jig was evaluated as to its ability to clinically verify the position of the abutment replicas on the master cast. MATERIALS AND METHODS A clinical evaluation was made on 58 edentulous arches necessitating rehabilitation with fixed partial dentures. Any broken jigs detected were replaced with a new set of jigs and clinically retested. Data were statistically confirmed. R...

Objective: To evaluate marginal discrepancies between cast implant superstructure and EDM processed implant structure. Materials and methods: For the purpose of this study, an experimental model was prepared on which nine cast implant superstructure in nickel-chromium were fabricated which was then subjected to EDM processing. One-screw test was used to verify fit of superstructure both preand ...

BACKGROUND Although recent reviews have suggested active smoking to be a risk factor for breast cancer, the association with passive smoke exposure remains controversial. This risk association was explored in a large prospective study of women, the California Teachers Study. METHODS Detailed lifetime information on passive smoke exposure by setting (home, work, or social) and by age of exposu...

This study investigated the energetics of the human ankle during the stance phase of downhill walking with the goal of modeling ankle behavior with a passive spring and damper mechanism. Kinematic and kinetic data were collected on eight male participants while walking down a ramp with inclination varying from 0° to 8°. The ankle joint moment in the sagittal plane was calculated using inverse d...

Cellular cargo can be bound to cytoskeletal filaments by one or more active or passive molecular motors. Recent experiments have shown that the presence of auxiliary, nondriving motors results in an enhanced processivity of the cargo, compared to the case of a single active driving motor alone. We model the observed cooperative transport process using a stochastic model that describes the dynam...

most of the researches do not differentiate between intuitive critic and passive one – in the field of features, applications and methods. this critical school is called emotional or passive critics which emphasizes aesthetics. thus sensitivity is not the only appliance to wisdom but is a mean to inspire happiness or unhappiness feeling. consequently the passive (critical) school is the result ...

We report the first experimental study of the dispersion of pairs of passive particles, performed in a controlled two-dimensional turbulent flow, in which Kolmogorov-Kraichnan scaling Eskd , k25y3 holds. The Richardson t3 law is observed, and strongly non-Gaussian behavior is obtained for the Lagrangian distributions of separations. The process is shown to be isotropic, and self-similar in time...

The inability to consistently achieve a passive fit with screw-retained implant prostheses is well documented in the literature. Cement-retained implant frameworks have been advocated for implant-retained fixed partial dentures. However, cement retention has not been routinely advocated for fixed-detachable hybrid prostheses. This article describes a method for fabricating a cement-retained fix...

Guided implant surgery is not completely accurate when using computer-designed stereolithographic surgical guides. Complications are frequently reported when combining computer-guided flapless surgery with an immediately loaded prefabricated prosthesis. Achieving passive fit of a prefabricated prosthesis on the inserted implants the same day of the surgery can be difficult. The aim of this repo...

Lateral Thinking is a set of related techniques primarily intended to support creative thinking Lateral Thinking is based on the idea that the Mind is a pattern making and using system The Mind is a Self-Organizing System, not a Passive Recording System The Mind reacts to every input by attempting to fit it into what is already known n This is a good source of Optical Illusions, since it is not...
