Definitions
- the invention relates to a method for computer-aided patient-specific representation and planning of dental and / or prosthetic work as well as for the preparation and subsequent supply with prosthetic workpieces according to the preamble of patent claim 1.
- the prepared state of the planning model thus obtained is then e.g. stored by optical and / or mechanical scanning of the given geometric configuration.
- the dental workpiece is then made in a known manner.
- the grinding and preparation of the teeth in the jaw to be restored is then carried out on the basis of the stored data of the prepared state of the planning model, this grinding being carried out by means of a numerically controlled milling and grinding device fixed in or on the patient's oral cavity.
- the prosthetic workpiece can then be inserted or cemented.
- the basic idea of the invention consists first of all in starting from a digitized image database which comprises a plurality of model tooth and jaw views.
- This image database contains images of both healthy and teeth with a wide variety of pathological changes or conditions.
- the stored data of the tooth and jaw views enable a two- or quasi-three-dimensional display on a standard computer monitor. It is within the scope of the invention that both complete rows of teeth and individual teeth are stored digitally in order to then be able to develop a synthetic jaw or denture representation in subsequent process steps, depending on the respective actual findings.
- the image database can not only contain two-dimensional, pixel-oriented descriptions, but also have data records that were obtained from three-dimensional models and have a vector orientation in addition to a pixel.
- patient-specific data is then recorded and this data is stored in a respective access-protected file.
- the computer and the associated monitor are then used to visualize the actual condition of the respective patient in accordance with the given finding.
- This patient-specific as-is state can be measured using a standard output medium, e.g. output and documented by a printer or given to the patient.
- a treatment database available online or offline.
- This treatment database contains at least information regarding the materials to be used in the treatment, the anticipated time and the estimated costs as well as a possible patient-specific treatment risk based on the entered medical history.
- the list of services of the corresponding health insurance company which may be subject to change, is used via online access.
- an automatically optimized therapy plan is derived.
- the optimization process is understood as the result of a selection of individual therapy steps and with regard to the patient interactive selection of these steps.
- the therapy plan itself is saved in another patient-specific, protected file for later therapy control and for billing and documentation purposes.
- a visualization of the patient-specific conditions during and / or after the treatment steps is presented on the basis of the therapy plan, again using the image database of the model views of teeth and jaws for deciding on decision-making for patients and practitioners.
- a data exchange with a dental laboratory is carried out via a preferably online connection, in order to record planning alternatives and / or to provide or call up planning aids, especially for prosthetic work.
- the image database preferably includes images of typical, age-classified male and female mouth regions, so that a convincing representation that is accepted by the patient can be achieved even without individual imaging can.
- a macro database for anamnesis analysis is used to ensure that patient-specific data can be recorded reproducibly and with little effort. With this database it is then possible to carry out an automatic risk assessment with regard to the subsequent treatment planning or individual treatment steps, look-up tables which are stored in the computer being usable for this purpose.
- elements or parts of the visualized patient-specific actual state i.e. can be moved or removed according to the image content, controlled by a cursor.
- the therapies that can be planned include conservative, surgical, prosthetic, functional, implantological, prophylactic and other measures.
- a daily schedule optimization can be derived for the attending physician and thus the ordering system as well as the time management can be significantly effective.
- No special software or computer skills are required to use the process, since the individual process sequences or steps are menu-supported and in dialogue are unwindable.
- less data is automatically derived from the digitized image database with the model tooth and jaw views without further intervention, the actual findings to be visualized.
- intraoral recordings are made with a corresponding camera both for visualizing the actual patient status as well as for later documentation of the treatment success after the therapy and the image data are stored.
- the described method offers the dentist or dental technician a virtual patient via the monitor display of a computer system, an optimized treatment strategy being able to be worked out with the aid of this presentable actual status and at the same time the desired treatment results and treatment successes can be presented to the patient in advance.
- the optimization and therapy planning carried out in this way also makes it possible to reduce the costs at the dentist and / or in the laboratory and to improve the time management both with regard to the required sessions and the daily planning of the doctor.
- the system is self-learning, ie empirical values and insights can be entered, i.e. risks are also uncovered by means of automatic statistical evaluation of repeated information or queries and are then subjected to a more detailed scientific investigation. For this, there is the possibility of withdrawing a subset of the patient-specific data in a patient-neutral manner and, as mentioned, subjecting them to a statistical evaluation.
