  • An artificial tooth is formed in a stable occlusal relationship if the denture is put in hot water for a while and then returned to the oral cavity and placed in a good place.
  • To adjust the occlusion of one or more artificial teeth it is possible to easily adjust the joints of the artificial teeth limited by light irradiation or a heat energy transfer device.
  • Occlusion can be adjusted while freely adjusting the position and height of the denture.
  • Thermoplastic mild material is fixed without changing the setting value of the occlusal adjustment such as the artificial tooth elevating device after the occlusal adjustment, further protecting the elevating device from external force, and increasing the strength of the artificial tooth itself, Provide high quality artificial teeth.
  • the artificial tooth of the present invention is useful for occlusal adjustment.

Abstract

La présente invention concerne une dent artificielle dont l'intérieur est pourvu d'un ressort comprimé et d'un amortisseur en matériau thermoplastique de façon à réaliser une dent artificielle résistante occlusalement stable. L'invention concerne plus particulièrement une dent artificielle dans laquelle l'amortisseur en matériau thermoplastique (1303) est essentiellement disposé dans une zone constitutive de la dent artificielle, entre la jonction (1300) et la face occlusale (1301). En outre, au moins une terminaison (1302) du ressort est solidaire de la jonction (1300) et l'extrémité supérieure (1305) du ressort étant solidaire de la surface occlusale (1301). Pour le réglage occlusal, on chauffe le tampon en matériau thermoplastique (1303) pour le ramollir, ce qui fait que le ressort comprimé (1304) a tendance à faire remonter la surface occlusale (1301) en réaction à sa compression. Il suffit alors que le patient morde en position d'occlusion centrée pour stabiliser dans cette position n'importe quelle dent artificielle grâce à la contrainte occlusale qu'exercent les dents opposées. Le refroidissement de la dent artificielle en position stable fait que le matériau de l'amortisseur durcit et donne à la dent artificielle sa forme.
