Title
(EN) DENTAL APPLICATOR WITH HIGH MATERIAL HOLDING CAPACITY
(FR) APPLICATEUR DENTAIRE A HAUTE CAPACITE DE RETENUE DE MATIERE
Abstract
(EN) An applicator (10) having a plurality of different size fibers (24, 26; 124, 126; 224, 226) capable of retaining a large quantity of liquid material. An applicator (10) having a handle portion (12; 112; 212) and an applicating end portion (14; 114; 214) in which different size fiber material is adhered to the applicating end portion (14; 114; 214). At least two different size fibers (24, 26; 124, 126; 224, 226) are used, with one being longer than the other. The at least two different lengths of fibers used range from 0.04 inches or 0.102 cm to 0.100 inches or 0.254 cm with a denier ranging from three to twenty-five. The use of a plurality of different sized fibers results in an improved applicator having increased liquid retaining properties. The present invention is particularly applicable to medical or dental procedures used in applying a liquid material. The present invention is particularly well suited in a dental procedure for applying a relatively large quantity of self-etching bonding liquid to a prepared cavity (20) in a tooth (18).
(FR) L'invention concerne un applicateur ayant une pluralité de fibres de taille différente (24, 26; 124, 126; 224, 226), capable de retenir une grande quantité de matière liquide, ledit applicateur présentant une portion formant poignée (12 ; 112 ; 212) et une portion terminale pour l'application (14 ; 114 ; 214), dans laquelle un matériau à fibres de taille différente est mis en place de manière à adhérer sur la portion terminale d'application (14 ; 114 ; 214). Au moins deux fibres de taille différente (24, 26 ; 124, 126 ; 224, 226) sont utilisées, l'une étant plus longue que l'autre. Les deux fibres de longueur différente utilisées se situent dans une gamme de 0,04 inch, ou 0,102 cm, à 0,100 inch, ou 0,254 cm, avec un denier compris entre trois et vingt cinq. L'utilisation d'une pluralité de fibres de taille différente permet d'avoir un applicateur amélioré, à propriétés de retenue de liquide accrues. L'invention s'applique particulièrement à des processus médicaux ou dentaires utilisant une matière liquide. L'invention est particulièrement appropriée pour l'application d'une quantité relativement importante de liant liquide « primer » pour une cavité préparée (20) dans une dent (18).
