Description

[0001] DENTAL COATING MACHINE

[0002] Technical Field

[0003] The invention relates to a dental coating machine that is designed to increase the durability of dental restorations and to eliminate ongoing failures in dental restorations.

[0004] State of the Art

[0005] Teeth are the hardest organs of the human body. In addition to their biting and chewing functions, they protect the appearance of the face and help with pronunciation. Foods consumed especially under the scope of developing technology cause teeth to decay and break. Dental coating is a type of teeth whitening and restoration technology. Dental coating restoration is the bonding of a layer of material similar to the normal tooth colour to the surface of discoloured or defective teeth in order to achieve the whitening or restoration effect. Popular dental coatings can be divided into resins. There are two types: coating and porcelain coating.

[0006] Porcelain coating is a repair method in which a thin layer of artificial porcelain restoration is bonded and fixed to the lip surface of the affected tooth to cover defects such as defects and colour changes that affect the appearance. In recent years, it has also been used as a preventive restoration treatment method. It is widely used in clinics and is especially suitable for the cosmetic restoration of young permanent teeth and front teeth with large pulp space.

[0007] Prosthetic dental restorations are divided into two basic structures as direct restorations or indirect restorations. Direct restorations are generally known as fillings and are based on the principle of applying a soft material to the cavity inside the tooth. The soft material is hardened to obtain a restored tooth structure and then integrated into the existing cavity. Indirect restorations are usually manufactured before use in the mouth and then the finished restoration is bonded to a suitable structure in the mouth (e.g. existing tooth structure, bone, synthetic implant abutment, etc.). Examples of indirect restorations include bridge applications, crows, onlays and coatings.

[0008] Porcelain coatings promote beautiful colour, reduced tooth preparation, anti-fluid absorption, good biocompatibility, wear resistance, periodontal health maintenance and strong and secure bonding. Porcelain coatings can be divided into three categories based on different manufacturing methods and materials: Traditional porcelain coatings, cast porcelain coatings and CAD / CAM machined porcelain coatings.

[0009] Porcelain is a white, translucent ceramic that is applied and fired until it becomes glazed. A core is usually first formed in a dental laboratory. Layers of porcelain are then applied to the outer surface of the core. These are heated to sinter / solidify the porcelain and create a physical fit over the core.

[0010] Porcelain coatings are advantageous in their ability to mimic the appearance of natural teeth by applying multiple layers of varying translucency. In such applications, good adhesion, high retention, prevention of micro leakage, fracture and fatigue resistance are important. In order to ensure good adhesion between the porcelain coating and the core material, various methods, including but not limited to particle abrasion, acid etching, application of bonding agents and silanisation of the core surface are used.

[0011] Within the framework of the technique of artificial porcelain dental restorations and coatings, it is aimed to achieve a match as close as possible to the appearance of the patient's natural dentition. In particular, the colour of the artificial restoration or coating is preferred be as close as possible to the colour of the adjacent teeth. Since natural tooth colour varies from person to person, the dental technician or dentist must be able to check the colour to match each patient's natural teeth.

[0012] There are many types of porcelain dental restorations. The technique used for colour matching will vary depending on the type of porcelain restoration being made. Modern porcelain restorations typically include porcelain bonded to a metal substructure. Porcelain typically comprises an opaque base layer, an intermediate layer of dentin porcelain, and an outer layer of enamel porcelain. In some cases, the metal substructure is coated with a bonding agent to facilitate the bonding of the porcelain to the metal. The colour of the completed restoration depends on the colour and opacity of the opaque, dentin, and enamel layers of the porcelain, the colour of the metal substructure, and the colour of the bonding agent, if used. In these restorations, the dental technician adjusts the colour of the overall restoration by adjusting the colour of each component of the restoration. Often the underlying metal substructure gives the restoration an unattractive greyish appearance. Attempts to mask the grey colour result in a thicker, more opaque porcelain that tends to look unnatural when compared to the natural translucency of human teeth. This is especially true when very thin restorations are used.

[0013] There are many disadvantages to the application of restorations consisting of high- strength ceramic cores and porcelain coatings. It was observed that notching occurred due to loss of adhesion at the core / coating interface and mismatch between the thermal expansion coefficients of the two materials, indicating that there was no chemical bond between the high strength ceramic core and the porcelain coating. Cracks occur in porcelain due to firing and the incompatibility between the thermal expansion coefficients of the two materials. The failures mentioned extend from small chips within the porcelain layer to the core / porcelain coating interface.

[0014] A new type of metal porcelain restoration has been introduced as disclosed in United States Patent No. 4,392,829, issued on July 12, 1983, and detailed below, in order to eliminate the mentioned disadvantages. Said invention relates to a dental restoration in which the metal substructure is a thin platinum foil with a textured surface to which the porcelain is directly applied. The foil is pressed onto a mould of the tooth, the foil is sandblasted to texture the surface, porcelain paste is applied directly to the textured surface of the foil, and the restoration is baked to harden the porcelain and bond it to the foil. The invention eliminates the need to apply a bonding agent to the foil, which was previously required to promote the adhesion of the porcelain to the foil. However, platinum foil has a grey appearance that presents the same colour matching problems experienced in the restoration of the previous technique. As can be understood from the mentioned document, it did not offer any solution to the colour problems experienced in the coating processes. The invention was put forth to eliminate the above-mentioned disadvantages and bring new advantages to the relevant technical field.

[0015] The Aim of the Invention

[0016] The main aim of the invention is to automatically perform the spraying process and automatically calibrate the heads during spraying.

[0017] The aim of the invention is to automatically adjust the pressure and temperature values for each area during dental coating.

[0018] Another aim of the invention is to determine the ideal colour value for the coated tooth by the coating machine according to the tooth structure and colour of the user and perform the coating process.

[0019] Another aim of the invention is to balance the colour distributions that occur during the coating process by determining the colour differences that occur in different areas of the tooth due to its structure.

[0020] As a result, it has been understood that it is appropriate to make innovations in the relevant technical field along with alternative solutions to all the above-mentioned problems.

[0078] This detailed description is explained only for a better understanding of the subject and in a way that does not create any limiting effect.

[0079] The invention, which is explained in detail below, is put forward to eliminate the colour differences that occur on the coated tooth in dental coating processes, to prevent incorrect or incomplete spraying due to the user's control during the formation of the tooth and to ensure that the resulting tooth structure is exactly the same as the user.

[0080] Figure 1 shows the external appearance of the coating machine (K). As shown in Figure 1 , said coating machine (K) comprises at least one body (1 ) and at least one cover (2) connected to said body (1 ) with a connection element (4). The body (1 ) is protected from any possible negative effects from the outside by means of said cover (2). Said cover (2) has a foldable feature, and in an alternative embodiment of the invention, the opening and closing of the cover (2) is automatically realised by touching the touchpad located on it. Again, in another alternative embodiment of the invention, there is a holding section inside the cover (2) to enable the user to lift the cover (2) in order to open it.

[0081] Again, as shown in Figure 1 , there is a carrying leg (5) under the body (1 ) to ensure that said coating machine (K) stands on the area where it is located, to prevent the body (1 ) of the coating machine (K) from coming into direct contact with the ground, and to ensure that the coating machine (K) moves on the ground when necessary. Said carrying legs (5) are connected to each corner section of the body (1 ) on the ground in order to ensure the balance of the coating machine (K) when it is on the ground and to prevent the calibration of the coating machine (K) from deteriorating during the coating process. In the alternative embodiments of the invention, the mentioned carrying legs (5) are positioned in the middle of the edges instead of the corners so that they are in equal geometrical dimensions with each other on the coating machine (K). In another alternative embodiment of the invention, weights are positioned on the carrying legs (5) in order to prevent the calibration of the machine from being disrupted due to the vibration that occurs when the coating machine (K) starts to operate and to prevent the tooth structure from being deteriorated due to the calibration errors during the coating process. As shown in Figure 1 , the carrying arm (3) is connected to the front of the body (1 ). By means of said carrying arm (3), the user is able to move said coating machine (K) manually in case s / he wants to change its place.

[0082] Finally, as shown in Figure 1 , the board (6) is positioned on the back of the body (1 ) in connection with the body (1 ). By means of said board (6), the electrical energy required to ensure the operation of the coating machine (K) is obtained and the necessary energy is produced to ensure the operation of the coating machine (K).

[0083] The detailed view of the internal parts and internal structure of said coating machine (K) is given in Figure 2. As can be understood from Figure 2, the protection block (27) is connected to the back of the body (1 ). Said protection block (27) protects the compressor (18) and the water tank (19) connected inside from external effects. The water used to activate the porcelain or zircon powder (these elements vary depending on the material to be coated) is stored through said water tank (19). There is a valve (22) connected to said compressor (18). The spraying of powder and / or water is controlled by said valves (22). Which material will be sprayed among powder or water is determined by the opening and closing of the valves (22). When the valve (22) is closed, the spraying process is allowed; when it is open, the spraying process is prevented. In an alternative embodiment of the invention, said valve (22) is a solenoid valve.

[0084] Again, as shown in Figure 2, there is a hose (23) that is connected to the water tank (19) on the coating machine (K) to ensure that water is transmitted from the water tank (19) to the spraying element (13). In an alternative embodiment of the invention, said hose (23) is a pneumatic hose.

[0085] Again, as can be understood from Figure 2, the temperature and humidity sensor (17) is positioned on the upper side of said protection block (27). Said temperature and humidity sensor (17) prevents the porcelain or zircon mixture (as mentioned before, coating materials vary depending on the characteristics of the product to be coated. Porcelain and zircon are indicated representatively) in the powder chamber (14) from drying out. Again, temperature and humidity are monitored by said temperaturehumidity sensor (17). In case of an increase and / or decrease in the temperature value or an increase and / or decrease in the humidity value in the powder chamber (14), the temperature and humidity sensor (17) goes into alarm mode and notifies to ensure that the powder chamber (14) reaches the previously determi ned / defined temperature and humidity value. A fan is positioned inside the powder chamber (14). Said fan is not referenced in the figures. In case of fluctuations in temperature and / or humidity values, the fan is activated by the temperature and humidity sensor (17) and the ambient temperature and humidity value of the environment reach the predetermined / defined value depending on the temperature, preventing the porcelain or zircon mixture in the powder chamber (14) from drying out.

[0086] The powder chamber (14) is a closed box containing porcelain, zircon, etc. materials. The powder chamber (14) is connected to the spraying element (13). The powder chamber (14) is automatically moved when the material selection of the tooth to be coated is made. The water carried from the water tank (19) to the powder chamber (14) is transferred via pipes (23) and the water mixture of the powder material to be used during the coating process is provided here. After the water is transferred into the powder chamber (14), it directly interacts with the material in the chamber and becomes ready for the coating process. The coating material and water mixture in the powder chamber (14) does not require an additional mixing process.

[0087] In an alternative embodiment of the invention, a barometer (not referenced in the figures) is connected to the coating machine (K). The water pressure and air pressure that continue to circulate in the coating machine (K) are controlled by means of said barometer, and the air pressure and water pressure are controlled under the conditions when the coating process is carried out.

[0088] Again, as can be understood from Figure 2, the rotary table motor (24) is positioned on the body (1 ). Said rotary table motor (24) is connected to the tooth holding element (7) and the rotary table (8). Said rotary table motor (24) converts the electrical energy transferred to it from the board (6) into mechanical energy and provides movement to the rotary table (8) and the tooth holding element (7) with the mechanical energy it obtains. Said tooth holding apparatus (7) ensures the fixation of the tooth structure to be coated during the coating process. Said tooth holding apparatus (7) has the feature of rotating 360°around its own axis. There is a rotary table (8) connected to said tooth holding apparatus (7) and positioned on the tooth structure to be coated. Said rotary table (8) rotates 360° around its own axis together with the 360° rotation of the tooth h olding apparatus (7) around its own axis. With the rotation of said rotary table (8) around its own axis by 360° the optical reader (not referenced in the figures) is enabled to see / analyse the dental prosthesis.

[0089] Said rotary table (8) is connected to the tooth holding element (7) with a magnet in an alternative embodiment of the invention. In case the tooth structure to be coated changes, the user is able to separate the connection between the rotary table (8) and the tooth holding element (7) and the time and labour losses that may occur during the operation of the coating machine (K) are eliminated. The rotation of said tooth holding element (7) and the rotary table (8) around their own axis by 360°is realised by means of the movement element (9) to which they are connected. With the rotation of the movement element (9) around its own axis by 360° t he other coating machine (K) elements to which it is connected also have the feature of rotating 360° around their own axis.

[0090] Again, as shown in Figure 2, the sensor (10) is positioned on the body (1 ) in the same direction as said tooth holding element (7). The sensor (10) is positioned on the sensor fixing element (1 1 ). In an alternative embodiment of the invention, the sensor (10) is a radar sensor that acts as a radar. The tooth structure is scanned by means of the sensor (10) in order to ensure that the calibration setting of the tooth holding element (7) and the rotary table (8) is made on the dental prosthesis. The geometric dimensions of the tooth structure and the formation process of the dental coating are monitored by means of the sensor (10).

[0091] In Figure 2, there is a spraying element (13) in order to ensure that the coating is made on the dental prosthesis with the material that is located in the powder chamber (14) and interacts with water and becomes ready for coating. A nozzle (26) is positioned at the tip of the spraying element (13) in order to ensure that the material stored in the powder chamber (14) is deposited on the prosthesis. The nozzle (26) is not connected to the robotic head (not referenced in the figures). There are nozzles (26) with different thicknesses depending on the process to be applied on the area to be coated. Again, as shown in Figure 2, the spray element (13) and the nozzle (26) it is connected to are connected to the profiles (25). The spray element movement system 1 (15) and the spray element movement system 2 (16) are positioned on the profiles (25) in order to provide movement to the spray element (13) and the nozzle (26) via the profiles (25). The spray element movement system 1 (15) allows the profiles (25) and the spray element (13) to move right and left; while the spray element movement system 2 (16) allows the profiles (25) and the spray element (13) to move up and down.

[0092] The spray element (13) movement system 1 (15) and spray element movement system 2 (16) provide movement to the spray element (13) and thus the coating material is distributed completely on the surface to be coated. In addition to the aforementioned situation, the change of the nozzle (26) is provided by the aforementioned movement / movement chain. The nozzles (26) reach the table where different types of tips are located depending on the movement of the spray element movement system 1 (15) and the spray element movement system 2 (16). The nozzle (26) that is located in the spray element (13) leaves the tip type it has on the table with the movement means contained in the table (not referenced in the figures) to which the spray element (13) is connected. It connects the tip of the required thickness to the nozzle in order to perform the previously defined process and goes back to the dental prosthesis. There is a door piston (12) to prevent any negativity due to air circulation in the nozzle (13) during the spraying process on the prosthesis from the nozzle (13) and to prevent dust and dirt from entering the nozzle (13).

[0093] Finally, as shown in Figure 2, the control unit (21 ) is positioned inside the body (1 ) in said coating machine (K) to control the processes taking place, to provide new data input to the coating machine (K), to ensure that the processes taking place are controlled from any mobile device, to ensure that the motors in the coating machine (K) operate and to stop them if desired, to monitor the spray process and to change the nozzle when necessary.

[0094] In an alternative embodiment of the invention, the movement of the coating machine (K) from its current position to another position is automatically realised by the control unit (21 ) automatically activating the carrying legs (5) with the data input made by the control unit (21 ). In another alternative embodiment of the invention, the temperature, humidity, pressure change and operating speed inside the coating machine (K) are controlled and monitored by the control unit (K).

[0095] The scope of protection of the invention is stated in the attached claims and cannot be limited to what is explained in this detailed description for exemplary purposes.

[0096] Because it is obvious that a person skilled in the art can produce similar structures in the light of those described above, without deviating from the main theme of the invention.
