CAD/CAM imaging in dentistry.

CAD/CAM (computer-assisted design/computer assisted manufacturing), although devised 20 years ago, has only been available for routine dental practice for 2 years. As a supplement to the conventional methods for making dental prostheses, CAD/CAM will have profound effects on the dental profession. CAD/CAM will improve versatility, accuracy, and cost effectiveness and will be a part of routine dental practice by the beginning of the 21st century.

[From joint to neuromuscular, from mechanics to electronics: the concept of neuromuscular compatibility].

The development of devices to record the functional mandibular kinetics, has permitted the physiological analysis of the masticatory cycles. Therefore, it is possible to consider a functional integration of the corrections, by addition or subtraction to the occlusal surfaces of the teeth. For this purpose, we have established the conditions of a physiological concept of occlusion taking into account the efficiency of the masticatory apparatus through a velocity analysis. This is the N.M.C. concept or concept of Neuro-Muscular Compatibility. This concept has led us to define the ISCA (Intra-Cuspid Spatial Angle), represented by the angle defined in the three spatial planes, by the trajectory of the occlusal contact point of a cusp liding over its opposite, in any excursive opportunity. We have shortly reported the studies by Levin on the SIROGNATOGRAPH and the prospects resulting from these studies. Then, we have studied in greater details the Saphon VISI TRAINER III developed by HOBO and described the various potentials of its use in the GBM Laboratory in Vienna (France), with François DURET. We have also analyzed the specific points which seem to represent the weaknesses of this device and have outlined some solutions to this problem. This approach, within a clinical context, may at term give rise to a complex analyser-expert-system intends to facilitate the establishment of a reliable diagnosis and to control the physiological integration of our procedures. The establishment, at term, of parameters and constants of this function, will guide this progression towards success.

A chronobiological investigation of fitness for work in women on a 220 cal 24 h protein diet.

In a group of nine healthy but obese women a set of tests were used to estimate several physiological and psycho-physiological variables: self-rating of hunger, mood and physical vigor, self-recording of grip-strength, muscular fatigue test, eye-hand skill, tempo, etc. Measurements were performed every 6-hours, at fixed times, during 24-hours, once a week, before (non-restricted spontaneous food intake) and for three weeks on a 220 cal. special protein diet (calcium caseinate: 55g, associated with potassium salts, water and vitamins). Findings relating to the metabolic and hormonal variables while on this diet have already been reported: (a) The diet does not alter the circadian acrophase (peak) of the variables and (b) two distinct metabolic steps occur: first a peak of gluconeogenesis and second, a phase when ketone bodies and fatty acids are used almost exclusively as source of fuel. The present findings show that so long as nitrogen remains in balance this restricted diet (a) does not change the grip strength and the muscular fatigue test; (b) does not alter the mood, the physical vigor etc. and (c) induces a statistically significant fall in "hunger" (self-rating method). We conclude that this low protein diet is compatible with non-strenuous work.
