The measurement and preparation method of tooth preparation for aesthetic restoration of anterior teeth

Abstract

The invention relates to an anterior tooth aesthetic repair tooth preparation quantity measuring method and a preparation method. The measuring method comprises the steps: A, carrying out the substantiation of a preparation quantity: obtaining a target repair body gypsum model by virtue of aesthetic wax pattern impression of an original model of a tooth; preparing the target repair body gypsum model to obtain a preparation body gypsum model; injecting a rapidly-hardened resin material into a silicone rubber guide plate obtained by pressing the original model of the tooth, placing the preparation body gypsum model into the silicone rubber guide plate, solidifying the rapidly-hardened resin material, and then removing the silicone rubber guide plate, thereby obtaining a preparation quantity body containing the preparation body gypsum model; B, measuring the preparation quantity body: measuring thickness of 3 to 13 key points determined by a cut end, a lip-tongue surface and two adjacent surfaces of the preparation quantity body; C, preparing a tooth: drilling a deep hole of the corresponding thickness in the key point corresponding to the tooth according to the thickness of each key point of the preparation quantity body, and polishing each surface, thereby completing the preparation of the tooth. By adopting the method, the preparation quantity of the tooth can be precisely measured, and the preparation of the tooth can be completed.

Description

technical field [0001] The invention relates to a measurement of a tooth preparation and a preparation method thereof, in particular to a measurement of a tooth preparation for aesthetic restoration of anterior teeth and a preparation method thereof. Background technique [0002] The aesthetic restoration of anterior teeth is to take measures to change the shape of the teeth and (or) periodontal tissue, and strive to achieve the greatest degree of coordination in the appearance and function of the teeth, so as to optimize the final effect of the restoration. For patients with restoration in the aesthetic area, aesthetic analysis and design are required first, and an aesthetic wax-up model is made on the basis of the patient's original tooth model, that is, the shape of the target restoration, and then the tooth (preparation) is carried out under the guidance of the shape of the target restoration. Preparation, striving to accurately replicate the target restoration as the fi...

Problems solved by technology

[0007] The above method needs to make multiple layers of silicone rubber guide plates and take them off and on repeatedly, which is cumbersome to operate and increases the patient’s discomfort

Moreover, this method cannot accurately measure the amount of tooth preparation, and the preparation error is large; it requires doctors to use clinical experience, and it is difficult for beginners to accurately grasp
