Inventor: PARRISH MILTON E
IPC: B60N2/90
Filed: 1995-07-13
Abstract: Le système de support multicouche permettant la conformation à un objet et le support de celui-ci comporte une première couche compartimentée (14) étanche aux fluides et contenant des billes (18) mobiles lorsque du fluide est introduit dans ladite couche, et immobilisées lorsque le fluide en est évacué. Une deuxième couche compartimentée (16) étanche aux fluides est adjacente à la première couche (14) et se déplace lorsque du fluide y est introduit. Les première (14) et deuxième (16) couches sont couplées l'une à l'autre et le mouvement de la deuxième couche (16) entraîne le mouvement de la première couche (14). L'introduction de fluide dans les deux couches (14, 16) permet la conformation de la première couche (14) à un corps (15), et l'évacuation du fluide de cette première couche (14) immobilise généralement les billes (18) qu'elle contient, ce qui donne une première couche (14) rigide profilée qui épouse les contours du corps en le soutenant. Un autre mode de réalisation met en oeuvre des couches (32, 34) renfermant des compartiments individuels (32a, 34a) qui sont sélectivement remplis et vidés indépendamment les uns des autres et à des pressions différentes pour permettre la conformation sélective des couches (32, 34).

Patent CA-2236412-A1 (CA)
Inventor: ROETZER PATRICK
IPC: A61C3/06
Filed: 1998-04-30
Abstract: A self-limiting dental composite restoration sculpting bur particularly adapted for sculpting occlusal resins.  Because of the cuspal angle of its cutting surface, the bur will make cuts that closely match the naturally occurring topography of human teeth as well as provide a visual stop that indicates when the desired cutting depth has been reached.  The apparatus also includes a diamond coated cutting surface that is of such a roughness that it creates a physical stop that sends a tactile response to the operator when the bur contacts enamel. This tactile response ensures that the operator can avoid overcutting the restoration.  In addition, a non-diamond coated annular band can be provided on the cutting head to create a safe zone which serves a further limit stop.  The bur is mounted on a straight shaft to allow maximum vertical adjustment when mounted to a standard dental drill.  The advantages include a visual depth stop, a physical stop, a shape that matches naturally occurring topography, and using a straight shaft to maximize vertical adjustability.
