Abstract
(EN)
A prophy chip comprising a hollow cup-shaped core of such type as canopy (semispherical) type, cylindrical type, cup type, cone type, inverted cone type or disk type, covered with a hydrophilic grindstone sponge containing a polishing agent, the hydrophilic grindstone sponge side edge either being press fixed by being folded into the interior of the core by a shank-equipped latch plate or undulated for gripping purpose, a shaft fixed to avoid resonance around the latch plate bottom surface rotation axis during rotation, thereby providing a cleaning, polishing and burnishing prophy chip which maintains polishing efficiency without involving transverse oscillations in polishing barrel-shaped tooth clearances or adjacent surfaces and without using a polishing gel or paste , with less heat generated by friction.
(FR)
L'invention concerne un copeau prophy, qui comprend un noyau creux en forme d'entonnoir de type auvent (semisphérique), cylindrique coupelle, conique, cône pointe en haut ou disque, recouvert d'une éponge hydrophile en calcaire ferreux contenant un agent de polissage, le bord latéral de ladite éponge étant soit fixé par pression par pliage à l'intérieur du noyau au moyen d'un plateau support de prisonniers équipé d'une tige, soit ondulé à des fins de préhension. Un arbre est fixé de manière à éviter une résonance autour de l'axe de rotation de la surface de fond du plateau support de prisonniers, pendant la rotation, ce qui donne un copeau prophy à nettoyer, polir et brunir qui conserve son efficacité de polissage sans entraîner des oscillations transversales dans des intervalles dentaires en forme de tonneau ou des surfaces adjacentes, sans utilisation de gel ou de pâte à polir, et qui génère moins de chaleur due au frottement.

 天丸(半球)型、円筒型、カップ型、円錐型、逆円錐型、あるいは円盤型などの内側が中空のカップ状の芯材部を、研磨剤を内包する親水性研磨砥石スポンジで被覆し、その親水性研磨砥石スポンジ辺縁をシャンクの付与された留め板で、前記芯材内側に折込むように圧入固定するか、あるいは挟持するための凹凸を付与し、その留め板底面部回転軸中心に軸回転時に共振することがないように軸部を固定したプロフィーチップによって、歯牙の鼓形歯間空隙や隣接面を研磨する場合も横ブレを起こすことなく、研磨ジェルあるいはペーストを使用することなくして研磨効率を維持し、しかも摩擦による発熱の少ない清掃研磨艶だしプロフィーチップを提供する。
