Industrially produced veneer for permanent attachment to a tooth

description

The present invention relates to devices and veneers for permanent attachment to teeth, methods of making the devices and veneers, methods and apparatus for securing the devices and veneers, the use of the devices and veneers, and kits of parts comprising the devices and veneers of the invention and other applications and embodiments of the devices and veneers according to the invention.

Veneers are thin ceramic shells that are attached labially to the tooth. Veneers serve to correct tooth color, tooth position and / or tooth shape. Veneers can be made both with and without inclusion of the incisal edge and the proximal contact. A veneer thus serves to veneer a tooth, in particular the labial side of a tooth in the visible area of the mouth.

Permanent veneers are made individually, usually by a dental technician or by CAD / CAM devices. Veneers can be made from a variety of plastic, composite or ceramic materials. To make an individual veneer, an impression is made of the tooth to be veneered. Based on this impression, a veneer can be produced by means of different methods, for example based on a model of the labially prepared tooth. The inside of the veneer is adapted to the specific labial surface of the tooth to be veneered. The inside, ie the oral surface, of the veneer is thus adapted to the individual tooth anatomy. The outside The veneer is smooth and designed as desired by shape and color, so represents the ideal or desired shape or ideal or desired color of the tooth to be blended. The veneer is applied to the tooth so that the veneer side, the oral surface as a negative represents the specific labial contour of the surface of the tooth, fits snugly on the tooth contour. Veneers are attached to the labial tooth surface using special adhesives or cements, such as fine hybrid composites. Due to the exact fit of the individually shaped veneer inner side, a uniform adhesive layer can be achieved when attached to the tooth. Corrections of tooth position and tooth shape are made by the design of the veneer in different thicknesses.

An overview of the conventional production and attachment to the tooth of permanent veneers is given by C. Hämmerle et al. "Dental Ceramics", Chapter 3 (pages 23 - 36), Quintessenz Verlags GmbH, Berlin (2008).

US Pat. No. 4,579,530 describes a method for producing a veneer made of high-performance ceramics, by means of which individual veneers with a very thin layer thickness of only 0.3 to 0.55 mm can be obtained. These veneers can be permanently attached non-invasively to the unprepared tooth with an adhesive. Again, corrections of tooth position and tooth shape are made by different thicknesses of the veneer. Such thin Porzellanveneers are known in the market as Lumineers ^®.

The surface of the inside of a permanent veneer is often prepared. The preparation can be achieved, for example, by fen with a diamond grinder or by sandblasting, for example, with an alumina-containing air stream done. This preparation results in a roughness of the prepared surface. The roughness of the roughened inner surface of a veneer is generally up to 60 .mu.m, in particular between 15 .mu.m and 50 to 60 .mu.m.

The usual veneer techniques require two medical appointments for the patient. At the first appointment the impression of the tooth is taken. The impression is then used to make the veneer. The insertion and attachment of the veneer to the tooth then takes place at a second appointment. This is costly and time-consuming for both the patient and the dentist.

EP 0054785 A1 proposes a method in which a veneer can be created at a doctor's appointment and attached to the tooth. This method is used for instance as a so-called CEREC ^® process. The doctor's appointment in this procedure, however, takes a long time because the veneer is made during the procedure. Also, the process is very costly because the dentist must use expensive special equipment such as a measuring camera and a computer-aided grinding unit.

The individual production of permanent veneers is so far very labor-intensive. The veneers must be individually manufactured by a dental technician. Due to the individual production a continuously high quality of veneers is not guaranteed. Above all, the individual production of veneers is very expensive. As a result, many patients are prevented from being treated with veneers. However, there is often a need not only for aesthetic reasons a supply of visible dental defects with veneers, but also the mental pressure is high in patients with visible dental defects. The real need for form and color corrections in the visible tooth area can not be nearly satisfied by the existing methods of making and securing permanent veneers.

Day veins or temporary veneers are made up, ie not made individually. They differ from individually made veneers in that their oral surfaces are not adapted to individual tooth anatomy. The insertion of the Tagesveneers takes place either by the dentist in a similar form as the insertion of individual veneers or by the patient himself with a provisional mounting material. Corrections of tooth position and tooth shape are made by different thicknesses of the fastening material that lies between the tooth and the vein. Tagesveneers are known for example from US 2005/0227204 A1. The veneers shown there have a completely smooth and even oral veneer surface.

Such day veins, whose oral surfaces are not adapted to tooth anatomy, can only be positioned extremely difficult and exactly on the tooth surface. Even small differences in curvature and shape of the tooth and veneer, as well as bumps on the labial tooth surface lead to a non-swinging and fixed insertion of the veneer is not possible. Also, when applying the Tagesveneers on the tooth is difficult to achieve an aesthetically good, especially ideal veneering of the tooth, as an incorrect positioning of the veneer leads to easily visible irregularities in the tooth image. Consequently Day veneers with a smooth oral surface are not suitable for permanent use as a veneer for a tooth.

There is thus a need for inexpensive, ready-to-use veneers which can be used as permanent veneers and in which a secure hold on the tooth is ensured and their use leads to an aesthetically desired result of the tooth veneer.

The present invention is based on the technical problem of providing a device which overcomes the deficiencies, in particular the indicated deficiencies, of the prior art.

The present invention is also based on the technical problem of providing a durable veneer that can be manufactured by machine, in particular by packaging and mass-produced. The present invention is also based on the technical problem of providing a durable veneer that can be manufactured industrially.

The present invention is also based on the technical problem of providing a durable vein that is available to the patient at a low cost.

The present invention is also based on the technical problem of providing a durable veneer that can be produced by machine and assembly in consistently high quality.

The present invention is also based on the technical problem of providing a device which solves a combination of two or more, in particular all, mentioned technical problems.

The present invention solves the underlying technical problem by providing a device according to the claims. The present invention solves the underlying technical problem in particular by providing a cup-shaped device for attachment to a tooth, wherein the surface of the inside of the device has at least two height levels.

Preferably, the device is in one piece or at least two parts, in particular two parts.

Preferably, the device is in one piece. In an alternative embodiment, the device is a veneer. The present invention solves the underlying technical problem by providing a veneer according to the claims. The present invention solves the underlying technical problem, in particular by providing a veneer, wherein the surface of the inside of the veneer has at least two height levels.

A veneer according to the invention is a plate which has a generally shell-shaped surface and has an outer side and an inner side. The inside of the veneer is the side that is attached to a tooth, especially on the labial front of a tooth. The surface that forms the inside of the veneer is also known as the oral base. The outside of the veneer is the side that serves the veneer, that is, the side away from the tooth. The surface that forms the outside of the veneer is also called a labial surface.

According to the invention, the oral base surface is at least partially concave. According to the invention, the oral base is preferably concave. According to the invention, the labial surface is at least partially convex. According to the invention, the labial surface is convex.

According to the invention, the oral base area is adapted in its dimensioning to the typical size of a labial front of a tooth.

According to the invention, the oral base area forms the first height level of the veneer. The distance between the oral base and the labial surface of the veneer should be understood as the thickness of the veneer. The shortest possible distance between a point of the oral base and a directly opposite point of the labial surface of the veneer is thus the section of the veneer with the smallest thickness.

The distance between the oral base and the labial surface of the veneer may vary. Even if the distance between the oral base and the labial surface of the veneer varies, the oral base forms only the first height level, since the height levels are according to the invention based on the oral base and not on the labial surface of the veneer.

An inventive veneer is as thin as possible, which means that the distance between the oral base surface and the labial surface of the veneer is as thin as possible. According to the invention, the distance between the oral base surface and the labial surface of the veneer is preferably between 0.1 and 2 mm. According to the invention, the distance between the oral base surface and the labial surface of the veneer is preferably between 0.2 and 1 mm. According to the invention, the distance between the oral base surface and the labial surface of the veneer is preferably between 0.3 and 0.8 mm. According to the invention, the distance between the oral base surface and the labial surface of the veneer is between 0.3 and 0.6 mm. According to the invention, the distance between the oral base surface and the labial surface of the veneer is at least 0.1 mm. According to the invention, the distance between the oral base surface and the labial surface of the veneer is at least 0.2 mm. According to the invention, be seen that the distance between the oral base and the labial surface of the veneer is at least 0.3 mm.

A veneer that is as thin as possible can be particularly advantageous if it is to be attached to a non-prepared or ground tooth.

It can also be provided in a veneer according to the invention in an alternative embodiment that the veneers comprise bent areas covering the incisal edge of a tooth. Of course, it may also be provided that the incisal edge is not covered. The possible coverage of the incisal edge according to the invention belongs to the oral base of the veneer and thus to the first height level. It can also be provided in an additional or alternative embodiment of a veneer according to the invention that the veneer incorporates the proximal contact. Also, the area which includes the proximal contact according to the invention belongs to the oral base of the veneer and thus to the first height level. Of course, it may also be provided not to include the proximal contact.

The first ^x height level of the surface of the inside of a veneer according to the invention is formed by the oral base of the veneer. Thus, the veneer base body is formed by the first height level and the labial surface, which represents a, preferably curved, platelet or small dish, wherein this main body of the platelet or bowl may be of different thickness at different locations. According to the invention, a thicker section of a veneer basic body does not constitute a second or further height step. The veneer basic body of a veneer body according to the invention For example, neers may correspond in dimension, shape, curvature and / or thickness to a typical veneer as known to those skilled in the art.

The dimensioning of the veneer base body is based on the dimensioning of a veneer from the prior art. One skilled in the art will be aware of typical thicknesses, widths, heights, radii of curvature, and shapes of a conventional veneer, such as a conventional day-vein. He can easily transfer these typical parameters to the basic body of a veneer according to the invention. In particular, he can choose dimensions which are typical for certain teeth, for example dentis incisivi, dentes canini, dentes praemolares or dent moles. One skilled in the basic dimensions and deviations in the dimensioning of labial surfaces of human teeth are known, so that he can easily generalize this dimensioning, can form an average value and / or transferred to a veneer according to the invention. The person skilled in the art can also combine different dimensions or manufacture various veneers according to the invention with different dimensions.

The surface of the inside of a veneer according to the invention has at least two height levels. The first height level is formed by the oral base of the veneer. The second and each additional height level has a greater distance to the labial area than would be the oral footprint at that point. The veneer is thus preferably thicker at the second and each further height level than at the first height level. The second and any further height level preferably form according to the invention. elevations that lie at the first level of elevation, ie the oral base area. Thus, the second and each additional height level elevations out of the first height level orally limited body of the veneer out.

According to the invention, the first height level with the lowest height preferably forms a concavely curved surface, and the further height levels represent elevations, or the upper ends or ends of the elevations, from the first height level.

The second and / or at least one further elevation, which form the height levels, of a veneer according to the invention can be shortened when using the veneer without much effort, that is, the corresponding height levels can be reduced in their distance from the first height level. The shortening can for example be done by grinding the surveys. By the Shortening certain height levels by certain lengths, the seat of the veneer can be changed on the labial surface of a tooth and thus obtain a desired seating position of the veneer on the tooth.

By shortening the second and / or at least one further survey, or the height level resulting from the survey, a difference in the radii of the veneer base and the tooth surface to be veneered can be compensated. Permanent veneers of the prior art are individually adapted to the curvature of the tooth to be veneered. Since the veneers according to the invention are produced according to the invention preferably prefabricated, their concave inner surface usually has a different curvature than the convex outer surface of the tooth. For example, the concave inner surface of the veneer may be more or less curved than the convex outer surface of the tooth to be veneered. Due to different curvatures of a Veneergrundkörpers with only one height level and a tooth surface of the Veneergrundkörper on the tooth either only with its central part, if the veneer has a larger radius than the tooth surface, or the Veneergrundkörper rests only with its outer edges on the tooth, if the veneer has a smaller radius than the tooth surface. However, this plays no role in the veneers according to the invention, since the at least second height level can be used as a support, which, in spite of differences in curvature, offers an additional contact point of the veneer to the tooth.

If a body has three points of contact with a surface that is not necessarily flat, the body lies on a surface. stable. This principle is realized, for example, in a tripod tripod. The inventors of the present invention have now found that even a veneer rests particularly stable on the surface of an individually shaped tooth and thus can be stably fixed to the tooth when the veneer has three points of contact with the tooth. If the points of contact are now formed by different height levels, the veneer can also be fixed exactly and in the desired position on the tooth by changing at least one height level, in particular by shortening at least one height level.

A veneer according to the invention with at least two height levels can be fastened firmly, stably and precisely to an individually shaped tooth in a simple manner. A veneer rests particularly stably on a tooth if it has three points of contact with the tooth. Then the veneer can not wobble, tilt or swing. The veneer can be tested on the tooth. If the veneer does not rest stably on the tooth, that is, has more or less than three points of contact with the tooth, the second height level or one or more of the further height levels can be shortened such that the veneer rests on the tooth with three points. By shortening the second and or one or more height levels, the veneer can also be adjusted so that it rests exactly on the tooth, that is in the desired position on the tooth. Then the veneer can be easily attached to the tooth.
