METHOD FOR PLANNING DENTAL TREATMENT

Abstract

Method for planning dental treatment which includes collecting data and images of the initial situation, creating an initial 3D model, studying the initial situation, analyzing the smile and planning in a center, all by means of software, creating and producing an envisaged final 3D model, creating a negative of the envisaged final model, creating in-situ a provisional prosthesis (mock-up) on the teeth of the patient which represents the final result which would be left after the treatment, reviewing the result and collecting photographs and video of the envisaged result and producing the required prosthesis, implant or brace elements from the digital data.

PREFERRED EMBODIMENT OF THE INVENTION

[0040] As can be observed in the attached figures, the method (1) for planning dental treatment is composed of various, clearly defined stages;

[0041] Step 1obtaining the information and different images, videos, radiographies, scans, etc. regarding the situation of the patient prior to the treatment (2).

[0042] Step 2the data obtained are transferred by means of computer software to a format in order to be digitally processed and to be able to obtain a 3D model of the initial situation (3).

[0043] Step 3by means of the universal analysis by the health personnel and the prosthetist, an analysis of the smile (4) is carried out, visualizing both the face and the teeth by means of using software in order to take into account the virtual model to be obtained as well as clinical planning of the technical and medical possibilities of obtaining this envisaged final result as a function of the limitation of space, bone, etc. or of anatomical impediments.

[0044] This phase is carried out in a diagnostic and planning center which can be a physical or virtual center accessible online and allows a group of specialists in each one of the fields required for the treatment to be able to carry out a diagnosis of the initial situation in order to then carry out an analysis of viability of the actions based on the initial data, together with a virtual simulation of the different phases, at the same time as the elements required for carrying it out are determined and the functional and production viability of these elements which help to guarantee the previously designed envisaged final result such as aligners, braces positioners for the orthodontics part of the treatment; surgical guides for the implant part of the treatment; or digital diagnostic wax-ups for the part of the treatment for selectively carving prostheses. All these elements are designed by a computer, starting from the envisaged final result.

[0045] Step 4the viable virtual model of the objective to be obtained at the end of the treatment is created (5) using the computer software and by 3D printing or any other technique which the physical model allows.

[0046] Step 5the creation of the provisional prosthesis (mock-up) which physically simulates the final result (6) and the physical review by the patient of the result with the provisional prosthesis (mock-up) in place and of the images previously collected (7).

[0047] This creation of the provisional prosthesis (mock-up) consists of two stages which are carried out in the laboratory and in-situ in the clinic itself.

[0048] One phase in the laboratory and the negative of the final model (61) is going to be obtained via this plastic model with the final situation of the patient by means of using plastic and by thermoforming or any other technique. We are going to obtain a plastic cover or mask (FIG. 4) adapted to the situation which the teeth would be in after the treatment.

[0049] This mask, mold or cover with the negative of the final model is already filled, in the clinic itself, with a resin, composite or any other material for obtaining a provisional covering and it is going to be placed over the teeth of the patient in such a way that once the resin or composite has set, and this cover, mold or mask is removed, the physical model, which was previously virtual and which now is a provisional prosthesis (mock-up) (62) remains in place on the teeth and the filler residues are removed.

[0050] Photos and videos with this provisional prosthesis (mock-up) in place are collected which can be digitally processed so that the patient can see the result most similar to the envisaged final situation (63).

[0051] The deviations from the envisaged final objective or the dissatisfaction of the patient with the result is transferred to the software program in order to be corrected.

[0052] Step 6production of the elements required for the treatment (8), subject to the acceptance of the same by the patient based on the initial situation and the final proposed model using the digital information available analyzed using the software program.

[0053] With the nature of the present invention sufficiently described as well as ways to carry it out in practice, all that remains to be added is that said invention may undergo certain variations in the form and materials thereof, provided said alterations do not substantially vary the characteristics which are claimed below.
