Embodiment Construction

[0066] With the method according to the invention, recording of patient information (putty impression, functional impression, occlusal registration) is achieved, for example, by:

[0067] (a) traditional impressions;

[0068] (b) Use of an impression tray that meets the following criteria: a muco-adherent seat, reduced border area, capable of accepting impression material, and capable of accommodating vertical mechanisms for occlusal adjustment and susceptible to posterior geometry for occlusal fixation The effect of shape.

[0069] (c) Digitization of optical records by means of suitable sensors

[0070] 1. By digital recording

[0071] 2. Via Computed Tomography

[0072] 3. By optical means.

[0073] Analog data obtained by taking an impression is converted into digital data. This can be achieved by digitizing the optical record as described in (c).

[0074] In the method according to the invention, the patient's condition is preferably recorded in...

Abstract

A method for preparing a partial or full dental prosthesis, including the following steps: 1.1. acquiring a patient's oral situation by taking an impression or by digital recording; 1.2. if required, digitizing the patient's oral situation; 1.3. selecting the teeth forming the dental prosthesis from a library of teeth or groups of teeth to obtain a virtual set-up of the teeth, which is positioned virtually in a space that takes the acquired patient's situation into account; 1.3.1 said library contains designs of dental arches, tooth shapes, tooth sizes 1.3.2 said library contains designs of the gingiva, and 1.3.3 said library contains total set-ups and / or modular set-ups for all of Angle's bite classes; 1.4. if required, modifying the set-up obtained from the library; 1.5. virtually embedding the teeth arranged in the virtual set-up in a virtual gingiva; 1.6 producing the real prosthesis.

Description

technical field [0001] The present invention relates to a method for the preparation of partial or full-mouth dental restorations. Background technique [0002] Today, high standards can be set when patients are fitted with partial or full dental restorations. The dentist prepares the patient for restoration, while the (partial) dental restoration is usually prepared by the dental technician in an external laboratory or in the dentist's office according to specifications obtained from the dentist. The quality of the restoration is highly dependent on the skill of the dental technician as a craftsman, and the quality of the specifications obtained from the dentist, which the dental technician must take into account when preparing the restoration. [0003] Furthermore, the preparation of the patient to be fitted with a prosthesis is often inconvenient for the patient. In this regard, for example, various sessions can be mentioned in the dentist's chair where an impression ha...
