Description

COMPLETE OIL GRINDING TEMPLATE

The subject of the invention is a composite template for grinding teeth and is a dental device that allows previously adjustable controlled guidance of the drill for proper and appropriate lateral and grinding teeth in height when preparing the location of the attachment of the crown, bridge or. replacement tooth or guidance of different rotating instruments and application of various tools (such as anesthesia administration) The invention is also used for dental treatment, insertion and administration of various medications and premedications, implant implant management, GBR (guided bone regeneration) surgical management. The invention belongs to the class A61C 1/08 of the international patent classification.

The technical problem that the proposed construction successfully solves is to enable the previously adjustable, precise and controlled teeth grinding, both side grinding and height grinding, to prepare the site for the replacement of a replacement tooth or a group of adjacent teeth, crown or bridge.

The invention generally relates to dental devices for providing the preparation of at least one tooth for receiving crowns, bridges and the like. In the known manner, anesthesia, appropriate fixation of the template and the beginning of the pre-treatment of the working environment are first appropriately applied, and a residual tooth or grinding is formed by grinding. stub, or similarly prepare two teeth to receive the bridge, that is, larger, joined teeth. Grinding design • · means removing material to achieve a large enough space for the crown or. mostička. Grinding and forming the remainder of the tooth (stubble) requires a lot of skill and concentration. Grinding is performed directly by the dentist in the mouth of the patient, so it may sometimes be difficult to properly and properly prepare the rest of the tooth to receive a crown, bridge or tooth replacement. When grinding, the most important thing is to ensure that the tooth or stub is properly shaped. The size and shape of the remnant of the tooth can be determined quite accurately in 3D X-ray examination of the head, jaw joint, teeth and bone substance, and it depends on the dentist's skills and knowledge whether this form can be implemented in the patient's mouth as well.

To support and eliminate the subjective errors of the physician, aids have been developed that allow for more accurate and less dental-dependent grinding and tooth formation in order to prepare for the placement of a crown or bridge, at least one tooth or substitute.

Thus, patent document WO 01/41667 describes a device that allows the preparation of at least one tooth for receiving a crown, a bridge or the like. The device has at least one centering body, an impression tray with threaded and detachable segments, a basic preparatory rail with sliding elements, a transmission and transport mechanism. The device, which is quite large and has many adjustable parts, should be placed in the patient's mouth on the lower or upper jaw and with the help of a properly designed tool, the tooth must be properly treated. The use of such a device is very difficult for the patient, and tooth preparation is very time consuming.

JP 8010268 discloses a device which enables the guidance of a suitably shaped head of a dental machine along pre-formed curves for the purpose of removing dental material in height or height. by. The device does not allow control at work, and due to the method of attachment, its functionality is limited.

According to the invention, the present technical problem is effectively solved by a composite template for grinding teeth, which consists of a basic attachment, io shaped by a jaw and an upgradeable attachment for lateral grinding or. a height-adjustable tooth grinder, with a removable lateral tooth grinder described by the inventive composite templates, tooth openings with pre-formed guide contours in the form of a 3D drill guide, while having a height-adjustable tooth grinder upper guide at the outer edge of the tooth openings guide surface, which is formed according to the required form of grinding teeth in height and slides the drill. Cooling ducts are also provided in the composite teeth grinding template.

The invention will be explained in more detail on the basis of an embodiment and figures showing:

Fig. 7 Dental turbine with interface.

The composite tooth grinding pattern shown in the accompanying 15 figures is essentially made of a base jaw 1 and a lateral grinding 2 or a height 2 grinding tooth.

The shape of the base attachment 1 shown in Figure 2 is adapted to the shape of the jaw. The positioning of the upgradeable extension 2 is enabled by outgrowths

3,4,5, which fit the grooves when installing the upgradeable extension 2

3a, 4a, 5a on the upgradeable extension 2. For fixing the upgradeable extension 2 on the base extension 1, holes 6 are made in the base extension 1 and holes 6a connected by the pins in the upgrade extension 2.

7.

In the base extension 1, which is placed on the jaw, there are openings 8,9 for teeth and terminals 10, 11 for the supply of refrigerant. The coolant must be fed to the tooth grinding site so that the tooth does not overheat.

The removable tooth grinding attachment 2 shown in Figures 2 and 3 has grooves 3a, 4a, 5a, holes 6a, hole 11 on its underside, which serves as a guide for the basic vertical support 17 io of the telescopic arm and in the openings 8a, 9a A 3D canal is performed for teeth, the shape of which is conditioned by the operation of the drill 12. The 3D canal is pre-made according to the 3D abrasive contour of the treated teeth. Channels 10a, 11a are also provided in the upgradeable extension 2, which together with the assembly of the base connection 1 and the upgradeable connection 2 in the front part are connected to the connections 10,11, while at the openings 8a, 9a they extend into the branches 10b, 11b by cooling the tool smoothly abrades the grinding site.

The positioning of the removable extension 2 'to the base extension 1 is enabled by outgrowths 3,4,5 which, when installing the upgradeable extension 2', correspond to the slots 3a ', 4a', 5a 'on the upgradeable extension 2'. For fixing the upgradeable extension 2 'to the base extension 1, holes 6 are made in the basic extension 1 and holes 6a' connected by the connecting pins 7 'in the upgradeable extension 2'.

The height-adjustable nozzle 2 'shown in Figures 5 and 6 has grooves 3a', 4a ', 5a', holes 6a 'on its underside and 8' on its upper side, 9 'guide surface 13, which is formed according to the required form of grinding of teeth in height and along which the drill 12 slides. In the upgradeable extension 2' there are also grooves 10a ', 11a' which, when assembled with the base attachment 1 and the upgradeable attachment 2 ' in the front they are connected to the connectors 10, 11, while at the openings 8a ', 9a' they extend into the junctions 10b ', 11b' in such a way that the coolant seamlessly coats the grinding site.

io Figure 7 shows a dental turbine 15 with an interface 16 that allows the dental turbine 15 to be retrofitted at work. For smooth operation of the drill 12 in the openings 8a, 9a, where it is limited in three linear spatial stages, and the restriction of two rotational spatial stages is enabled by a telescopic arm consisting of a basic vertical support 17, a main horizontal support 18, an auxiliary horizontal support 19 and an auxiliary vertical carrier 20. The telescopic arm elements 18 and 19 allow the distance from the axis of rotation of the axis of the vertical carrier 17, which is inserted into the hole 11 of the superstructure 2, to be altered and to prevent all spatial rotation rates. The element of the vertical support 17 and the interface 16 allow rotation about the vertical axis, which in turn allows the micromotor or gear turbine 15 to move freely and permits rotation about the vertical axis.

Composite tooth grinding template according to the invention, the construction description of which is given in the present description satisfactorily solves the set technical

the problem of performing pre-adjustable, precise and controlled grinding of teeth, both lateral grinding and grinding of teeth in height, for the purpose of preparing a site for the placement of a replacement tooth or a group of adjacent teeth, crowns or bridges. In addition, the template according to the invention also enables smooth operation in the sense of overheating of the teeth during treatment by effective cooling with a coolant through the implemented cooling channels and manifolds.
