Definitions

  • the present invention relates to devices, systems, and processes for removing tooth structure, and in particular to systems and processes for preparing instrumentation, as well as to such instrumentation, for use in preparing teeth to be aligned using dental aligners or to receive dental restorations.
  • IPR interproximal reduction
  • abrasive metal strips, diamond coated disks rotating at high speed on the end of a handle, and air rotor stripping (ARS) using a thin dental bur on a dental handpiece have been used to remove the portions of the tooth structure for the IPR.
  • Interproximal reduction templates have been introduced to provide some guidance for dental practitioners when using a tool to remove tooth structure in an IPR process.
  • Such templates include a guide slot formed with a hard material such as zirconium or porcelain that contact a cutting surface of the tool to limit the amount of tooth structure to be removed during an IPR process. Contacting vibrating cutting tools with these hard surfaces causes a reverberation effect that limits control of the cutting tool. The materials for these hard surfaces are also relatively costly providing an additional barrier for practitioners and their patients.
  • a working tooth to be treated in the mouth of a patient may be prepared by a process.
  • a first surface of a guide device may be secured onto one or more teeth of the patient to fix the position of the guide device relative to the one or more teeth.

Abstract

Une dent de travail à traiter dans la bouche d'un patient est préparée. Un dispositif de guidage est assujetti sur les dents pour fixer sa position. Un dispositif de coupe inséré dans le dispositif de guidage est déplacé de telle sorte qu'une bride du dispositif de coupe coulisse le long d'une fente s'étendant à l'intérieur du dispositif de guidage et entre en contact avec celle-ci et de telle sorte qu'un outil du dispositif de coupe retire des parties de la dent de travail, ce qui forme une surface préparée de la dent de travail. L'outil comporte une partie ayant un profil incurvé à l'intérieur d'un plan qui comporte un axe de l'outil de telle sorte que la dent de travail soit arrondie par la partie d'outil. Les dispositifs de coupe et de guidage sont retirés de la bouche du patient. Un dispositif d'alignement de dents est fixé sur une pluralité de dents comportant la dent de travail de telle sorte que le dispositif d'alignement de dents soit face à la surface préparée.
