Description

PROTECTIVE MATERIAL PRODUCTION WITH THREE DIMENSIONAL PRINTER IN ORTHODONTIC TREATMENT
Technological Field:
The present invention relates to the production of three-dimensional printer and protective material at the end of orthodontic treatment used in the field of orthodontics in the dental sector.
Known State of Technology:
All over the world, as a procedure, when orthodontics treatment is finished, protective materials (such as the lingual retainer) are used so that the teeth do not become distorted and to return to their previous state.
In current methods, the physician examines the patient and decides for the end of orthodontic treatment. In the same session, the physician takes the measurement from the patient and controls the measurement by removing it from the patient’s mouth. If the measurement is taken well, gypsum model is formed by pouring gypsum in the model, in the laboratory. Once the gypsum model is hardened it is removed from the model. The gypsum model is supplied to the technician and the technician bends the protective wire on the model. The wires are delivered to the physician and the physician applies the protective wire to the patient (adheres to the relevant teeth). In these process steps, measurement is made in the construction of the protective wire and the creation of gypsum models creates a cost and time loss.
US Patent Application No. US201815914688 discloses "Orthodontic Application". In the application, the device comprises an upper member intended to be mounted on the upper teeth during use and a lower member intended to be mounted on the lower teeth of the patient in use. Each of the elements is provided by a vacuum-shaped plastic material formed on a model of the patient's teeth. The model of the patient's teeth is formed by taking a mold of the patient's teeth or by digitally scanning the teeth.
“Orthodontic Retainer Production Method” is described in patent application CN20171536091. The invention discloses a method for producing an orthodontic holder that belongs to the dental orthodontic field. In the method, it is first provided to obtain a three-dimensional model of the chin and face on a lens, to perform the repair treatment, to form an associated orthodontic holder model based on the dental jaw-face model of the lens.
W02013CA00632 numbered patent application describes the method and system for orthodontic devices. The method according to the invention is "examined" upon a computer system to highlight the contour line of the teeth after digitizing the patient's virtual tooth cast and to determine the most suitable placement path for the orthodontic holder according to embodiments of the invention. A wire frame and cage are then designed to utilize the fixing portion of the tooth.
Patent application WO2017IB57161 discloses a "Three-Dimensional Orthodontic Retainer and Method for Generating a Three-Dimensional Orthodontic Retainer". The method of producing the three-dimensional orthodontic holder comprises the following method steps: forming a three-dimensional model of the structure of the patient's teeth; designing a customized, fully fitting model of the holder; It is in the form of producing the holder based on the 3D model designed with computer controlled stacking or material application. In the production of the product according to the invention, in extra oral scanning devices such as X-ray machines, the three-dimensional structure of the teeth is determined by digital audio tomography.
In the aforementioned patent applications, digital scanning process and model application methods are discussed. One of the biggest disadvantages of the 3D modeling process used in the mentioned methods is the high cost and the considerable time. In addition, the application is quite difficult. As a result, there is a need for a new technology which enables the modeling process to be realized in a short time by guiding the physicians who can overcome the above mentioned disadvantages, which allows the modeling process to be done in a short time, with little cost and no production time.
Definition of Invention:
The present invention is done by a three-dimensional printer and protective material production at the end of orthodontic treatment which can overcome the aforementioned disadvantages. It is a new technology which enables the modeling process to be realized in a short time by providing guidance to the physicians, enabling the modeling process to be realized in a short time, with little cost and no production time.
The method of application of the product according to the invention is as follows; The physician examines the patient and decides on the end of the orthodontic treatment. In the same session, the physician scans the teeth with a 3-D scan. It sends the scan file to the software on the computer. The scanning file is organized in Autodesk Tinker CAD software to be ready for 3D printing. After the editing, the protective material from the 3D printer (if desired, the gear model) is printed. The wires are delivered to the physician. The physician applies protective wires to the patient (adheres to the relevant teeth).
At the end of orthodontic treatment with the product of the present invention, the process of taking measurements, forming a plaster model and creating a protective wire; Intra oral scanner is used to scan the teeth in 3D. The scanning file is created with Autodesk Tinker CAD software and the protective wire is produced with bi-compatible polylactic acid (PLA). The protective wire is obtained by pressing with a 3D printer. After the protective wire is taken from the printer, it is modeled with heated spatula for rough and burr parts and the production is completed. In this way, speeding up of the process, eliminating the cost of gauge-plaster, saving time and improving the comfort of physician and patient Costs are reduced with the product of the present invention. The use of impression material and plaster has been canceled. These processes are applied in three dimensions. Since the protective material was prepared with software and produced with three- dimensional printers, the need for technicians also eliminated. In combination with the invention, the physician is able to print on the printer and produce protective material by arranging the inside of the mouth and editing by means of computer software. In the traditional method, this method exceeds 40 minutes. In addition, protective materials can be designed to match the teeth in the software will be in high compliance with the teeth. Depending on the measurement process, the patient's nausea reflex, bad taste in the mouth and the presence of measurement materials in and around the mouth were eliminated.
