Embodiment Construction

[0057] according to figure 1 and figure 2 , The device described in the present invention includes a fixing bracket 1 for placing in the patient's oral cavity. The fixing bracket 1 is generally "U" or "V" shaped, and is distributed on a symmetrical axis with the central plane Δ where the customer is located. It can be obtained by plastic grinding or thermoforming. It includes an incision area 10 formed so as to conform to the general curve of the tooth D of the patient. The incision area 10 has an occlusal area which can come into contact with the teeth D when it is inserted into the patient's mouth, the jaw edge 11 on the side adjacent to the throat; the jaw edge 12 on the side adjacent to the lips.

[0058] In order to fix the bracket 1 in the oral cavity of the patient, a firm root screw 13 needs to be prepared for the bracket. These root screws 13 are arranged in the region of the molars in the occlusal area. Fix it on the molar tooth of the dental arch where D1 is t...

Abstract

The invention relates to an intraoral device for automated preparation of the teeth with a view to performing partial or peripheral dental restoration, which includes: a splint (1) suitable for being positioned in the mouth of a patient, said splint including a means (13) for maintaining the position thereof inside said mouth; at least one mobile cutting tool (2) combined with said splint; and an electronic management unit which makes it possible to control said cutting tool, characterised in that: said cutting tool (2) is configured so as to cut at least the labial surface of the tooth (D1) to be prepared, said tool being mounted on a mobile carriage (23) moving along a rail (24) attached to the splint (1), opposite the labial surface of the tooth (D1) to be prepared, said rail having a curvature that matches the dentition (D) of the patient; said splint (1) includes at least one 3D digitisation tool (4) arranged such as to digitise at least the labial surface of said tooth to be prepared, said digitisation tool being connected to the management unit (6) so that the digitised data can be transferred to said management unit; and said management unit is configured so as to control the movement of said cutting tool (2) in accordance with the digitised data.

Description

technical field [0001] The invention relates to an automatic tooth body preparation device in the oral cavity, so as to restore part of the tooth body or nerves around the tooth body. [0002] The invention relates to a dental technique capable of preparing a patient's teeth so as to form an occlusal plane. More particularly, the present invention relates to automated dental equipment capable of performing automatic cutting within the oral cavity without the need for the dentist to operate the cutting tool. Background technique [0003] Ceramic occlusal planes can improve vestibular surfaces of teeth that are stained, discoloured, deformed or have slight wear. In particular, it is necessary to place the occlusal plane between the central incisors and the first premolars. To prepare the tooth for the occlusal plane, the dentist should remove the thin layer of enamel from the vestibular side of the tooth. The prepared dental impression can then be taken and sent to the labo...
