  • a device having opposed upper and lower jaw members 10, 11 and 12, 13 for respectively receiving the user's upper teeth and lower teeth in the spaces 14, 15 between the jaw members.
  • the device includes a connecting portion 20 so that the device as a whole has a generally H shape.
  • the opposed pairs of jaw members 10, 11 and 12, 13 draw together as a result of deformation of the portion 20 so that the opposed inner faces 16, 17 and 18, 19 of the jaws engage with the. user's teeth and chewing actions cause the faces 16, 17, 18, 19 to rub against and clean the teeth.
  • the portion 20 has projecting ribs 21, 22 to engage the teeth particularly the premolars and molars to assist dislodgement of food particles.

  • the upper and lower jaw members 10, 11 and 12, 13 move towards each other as shown by arrows B so as to engage or increase the engaging force on the teeth.
  • a biting action is used by the user to apply the forces in the directions A.
  • the opposed faces 16, 17 and 18, 19 of the jaw members therefore engage with the inner and outer faces of the teeth and subsequent grinding, rotary or reciprocating movement of the user's teeth while continuing to apply force causes the opposed faces of the jaw members to rub against and thereby clean the user's teeth.
  • the dimensions of the jaw members 10, 11 and 12, 13 may be chosen so that some massaging of the gums is also effective by the extremities of the jaw members.
  • the connecting portion 20 in Figs. 2 and 3 is provided with a cavity 23 defined by upper and lower walls 24, 25 which are deformable as shown in Fig. 3 by the application of force by the user's teeth.
  • the cavity 23 extends substantially across the entire width of the connecting portion 20 between the opposed jaw members 10, 11, 12 and 13.
  • the inner face 17 of the jaw member 11 is relatively highly porous compared to the outer face 25 so that the inner face 17 can be impregnated with toothpaste or other such materials which can be released upon use of the device.
  • the jaw members 10, 11, 12, 13 are concave and approach each other more closely at the mouth 30 of the spaces 14, 15 between the opposed jaw members, the narrowed mouth 30 ensuring a close fit particularly towards the teeth roots where the food particles and plaque can be located and where the teeth can curve inwardly at the edge of the gums.

Abstract

Dispositif d'hygiène buccale en forme de bande allongée de matière élastique présentant à l'usage une forme généralament arquée ou en ''U'' destinée à être introduite dans la bouche de l'utilisateur et comportant une paire d'éléments mâchoires (10, 11; 12, 13) opposés qui reçoivent les dents de l'utilisateur. Une portion de laision (20) s'étend entre les éléments mâchoires de sorte que ceux-ci se rapprochent lorsqu'une pression est appliquée à la portion de liaison (20) par le serrage des dents de l'utilisateur sur la portion de liaison afin de pousser les éléments mâchoires (10, 11; 12, 13) contre les faces avant et arrière des dents. Un mouvement relatif de broyage, de rotation ou de va-et-vient des dents supérieures et inférieures de l'utilisateur fait que les éléments mâchoires opposés frottent contre les faces avant et arrière des dents et les nettoient. Les faces internes (16, 17; 18, 19) des éléments mâchoires (10, 11; 12, 13) qui sont en face l'une de l'autre et qui se mettent en contact avec les dents sont composées de matière légèrement abrasive. La portion de liaison (20) comporte une structure relevée (21, 22, 31) saillante dans la région (14, 15) entre les éléments mâchoires opposés (10, 11; 12, 13) de sorte que la structure relevée (21, 22, 31) puisse entrer en contact avec les particules et en permettre le détachement des surfaces des dents opposées, en particulier des prémolaires et des molaires des mâchoires supérieure et inférieure de l'utilisateur. La portion de laision (20) est dotée d'un creux (23) ou d'un noyau (36) de matière plus souple que la matière de la portion de liaison (20) qui l'entoure, afin de faciliter la déformation.
