Definitions

  • One-part dental implant for fitting in a jaw consisting of an insertion component which can be fitted in the jawbone and a support component, that in the implanted position protrudes beyond the jawbone, for fixing a dental prosthesis, the support component and insertion component lying in the extension of one another and abutting one another.
  • Implants are used in dentistry, a cavity being drilled in the jawbone into which the implant is screwed tight or is pressed in. A dental prosthesis or crown is fitted on that part of the implant which protrudes beyond the gingiva.
  • a disadvantage which arises with known implants is that a completely natural imitation of an original tooth is not possible with these.
  • Known implants are usually cylindrical so that their shape is adapted in the optimum manner to the cylindrical cavities.
  • stress shielding usually arises as a result, which means that the bone present is resorbed in locations where there is no stress on the implant.
  • the contour of the neck of the tooth of known implants is also usually cylindrical, so that the interdental gingiva, or the papillae, does/do not assume a natural garland shape or does/do so only with difficulty. Furthermore, the metal of known implants can show through the gingiva so that a local (grey) discoloration is produced.
  • the procedure when fitting a dental implant is generally as follows:
  • the old tooth element is removed and/or the jaw is built up and the implant is fitted, usually punched, into the natural or built-up alveolus.
  • An impression of the teeth, or at least of the relevant portion of the jaw, is then taken, on the basis of which a dental technician makes a customised crown.
  • a one-part implant of the type indicated in the preamble is disclosed in US-A 4 199 864.
  • two types of one-part implant are disclosed in this publication.
  • the first type as is shown, for example, in Fig. 1 of US-A 4 199 864, is a one-part implant having an insertion component, that replaces the natural root, with an artificial crown, formed as an integral whole with the insertion component, directly on top.
  • this type of one-part implant does not closely resemble the type of one-part implant to which the present invention relates.
  • the present invention relates far more to the second type of one-part implant shown in US-A 4 199 864.
  • the artificial crown is a separate component that is fitted on the support end of the one-part implant after the latter has been fitted.
  • the one-part implant itself consists of an insertion component which can be fitted in the jawbone and a support component, that in the implanted position protrudes beyond the jawbone, on which the dental prosthesis, the so- called artificial crown, is fitted.
  • the support component and the insertion component lie in the extension of one another and abut one another.
  • the original tooth element is taken as the starting point.
  • This original tooth element is used to make a mould, the shape of the mould cavity of which corresponds to that of the original tooth element.
  • a hard plastic pin is inserted in the mould cavity and the remainder of the mould cavity is filled with a mixture of plastic and leachable crystals.
  • the top of the pin ultimately forms the so-called support component and the bottom of the pin forms the reinforcement of the root component, also referred to as the insertion component.
  • a one-part implant is obtained that can be fitted in the jaw as an integral whole. This is in contrast to implants where first the so-called insertion component is fitted in the jaw and then the so-called support component is fitted thereon, in order then to fit the crown on the support component.
  • a disadvantage of the implant according to US-A 4 199 864 is that in practice it is far from always easily possible to fit the "exact replica" in the jaw in accordance with the original tooth element. This can then lead to problems when fixing the crown on the support component of the implant in a subsequent step. It is true that the crown can be made such that it fits exactly, but the implant fitted in the jaw will be visible at the bottom of the crown as a consequence of incorrect abutment with the gingiva, which the patient finds unpleasant.
  • Implants of the two-part type that is to say with which the insertion component and support component are joined to one another, for example by a screw connection, after fitting the insertion component in the jaw are, for example, disclosed in USA 5 695 337 and WO 97/30654.
  • Both publications disclose that the support component can be made of zirconium oxide.
  • WO 97/30654 states that an advantage of a support component made of zirconium oxide is that this can be individually ground in a dental laboratory, or its shape can be matched to the patient by means of grinding operations. According to USA 5 695 337 it is possible to adjust the insertion component to size in the mouth, that is to say after fitting the insertion component.
  • the aim of the present invention is to provide a one-part implant having a support component that protrudes beyond the jawbone for fixing a dental prosthesis, a so-called crown, it being possible to correct the shape of the support component in order, for example, to support the gingiva or at least to provide a very accurate approximation to the natural shapes.
  • the Applicant has come to the insight that said aim can be achieved if the support component, or at least an external peripheral portion thereof, is made of a ceramic material of a thickness such that said ceramic material can be partially removed in order to adapt the shape of the support component.
  • the opinion has been that when a ceramic material is used in the support component this support component has to be a separate component that is fitted on the so-called insertion component later on. The reason for this is that otherwise the so-called support component would splinter off or would otherwise become damaged or broken when driving the insertion component into the jawbone - during which operation forces have to be exerted on the support component in the case of a one-part construction.
  • a ceramic material made of zirconium oxide, or at least based on zirconium oxide is outstandingly able to withstand the forces exerted when driving the support component into the jawbone, even if the entire one-part implant has been made from essentially solid zirconium oxide, or at least a material based on zirconium oxide.
  • other ceramic materials are also found to be very suitable, it optionally being possible to provide a core, for example a metal core, in the implant, which core extends to the top of the support component in order to absorb the forces exerted on the support component when driving in.
  • the support component that in the implanted position protrudes beyond the jawbone, or at least the ceramic peripheral portion of said support component can be matched, for example by grinding, to the shape of the dental prosthesis, even down to below the gingival margin. Consequently, a very accurate approximation of the natural shape can be obtained.
  • the arch or garland shape of the gingiva can be accurately approximated since the ceramic material of the support component can be filed away or ground in such a way that said support component abuts to just beyond the top edge of the jawbone. It is pointed out that according to the present invention it is conceivable for the entire implant, that is to say both the support component and the insertion component, to be made of a ceramic material, optionally completely or partially covered with a coating.
  • the ceramic, external peripheral portion extends from the jawbone to beyond the jawbone in order to be able to form a shoulder in the support component, to support the dental prosthesis, by partially removing the ceramic material, which shoulder, in the implanted state, follows the shape of the top edge of the jawbone running around the implant and abuts said top edge or is located just above it.
  • the support component is adapted to the bone line of the jawbone, as a result of which, in contrast to implants which function with screws or abutments, a natural gingiva line is obtained. After fitting the dental prosthesis on the shoulder following the bone line, the implant is then, moreover, entirely hidden from sight by the gingiva and the prosthesis.
  • the ceramic material is a material that can be ground or filed when the implant is in the implanted position.
  • the shape of the implant can be accurately adapted using filing and grinding tools conventionally used by a dentist.
  • this has the advantage that in this way it is also possible to compensate for inaccuracies in fitting the implant.
  • the implant cannot be inserted quite as deeply into the jawbone as was envisaged when adapting the shape in advance.
  • the shape of the implant is partially or completely adapted prior to implantation. This can then optionally be carried out in a dental laboratory.
  • the shape of the implant has already been adapted prior to implantation, it is possible even after implantation to adapt the shape of the implant according to the invention even more accurately, or further to machine the shape.
  • the ceramic material preferably the entire peripheral surface of the support component, is of a colour that matches the teeth, such as whitish or yellowish.
  • the insertion component narrows, in particular tapers, towards the free end thereof. So as to have to remove as little ceramic material as possible prior to implantation or after implantation when adapting the shape of the support component, it is advantageous according to the invention if the support component narrows, in particular tapers, towards the free end thereof.
  • the implant has its largest cross-section, or cross-sectional surface area, in the transition region from the insertion component to the support component.
  • said transition region is provided with a protuberance, preferably a coving, extending in the peripheral direction of the implant.
  • the implant according to the invention can have one or more of the following dimensions: the cross-section in the transition region is at least approximately 3 mm; and/or - the length of the insertion component is at least approximately 10 mm, such as approximately 12 mm or more; and/or the length of the support component is at least approximately 5 mm, such as approximately 6 mm or more.
  • the ceramic material will be zirconium oxide, or at least a ceramic material based on zirconium oxide.
  • Zirconium oxide is naturally glassy, but can easily be coloured to match the teeth by using a colorant, which is to be preferred according to the invention.
  • Zirconium oxide is also a ceramic material that is very suitable for punching into the jawbone since it does not readily tend to splinter and crack.
  • the support component is essentially made completely of ceramic material and/or the transition region from the insertion component to the support component, at least at its outer periphery, is made of said ceramic material; and/or the insertion component is essentially made completely of said ceramic material.
  • the entire implant will be made of said ceramic material, in which case zirconium oxide or a material based on zirconium oxide is particularly suitable.
  • essentially made completely is not understood to mean “made exclusively of. "Essentially made completely” does not preclude the relevant portion of the implant also being covered by a layer, such as, for example, a coating.
  • a coating in particular a coating that promotes bone intergrowth.
  • Such a coating can itself be a ceramic material, but can also be a different material. In this context consideration can be given to, for example, Al O 3 or hydroxyapatite or some other material.
  • the insertion component is at least triangular, such as, for example, rectangular or pentangular.
  • the cross-section or radial section of the insertion component of the implant is oval.
  • the present invention further also relates to a method for fitting an implant in a jaw, said implant having an insertion component, to be fitted in the jawbone, and a support component provided thereon which is intended to protrude from the jawbone in the implanted position, at least part of the peripheral surface of the support component being made of a material that can be ground, in particular a ceramic material that can be ground, and the method comprising the following steps: fitting the insertion component in the jaw, in particular in an alveolus, that can be either natural or artificial; grinding away peripheral material from a support component, when the latter has been implanted in the jaw, in order to adapt the shape thereof and fitting a dental prosthesis, in particular a crown, on the support component.
  • grinding peripheral material away from the support component is carried out in such a way that a shoulder for supporting the dental prosthesis is formed at the level of the top edge of the jawbone surrounding the implant, which shoulder narrows the support component and follows said top edge.
  • the implant according to the present invention can be fitted immediately after removal of a natural tooth. In situations where the natural dentition has long since disappeared, it is necessary to build up the jaw beforehand and to fit the implant in a second stage.

Abstract

L'invention concerne un implant dont la couleur correspond à celle de la dent, qui est conçu pour être fixé dans la mâchoire au moyen d'un élément d'insertion pouvant être planté dans l'os de la mâchoire, et qui possède un élément de support servant à fixer une prothèse dentaire. Cet élément de support est conçu pour former une saillie au-delà de l'os de la mâchoire quand l'élément d'insertion est en position d'implantation. Cet élément de support, ou au moins une de ses parties périphériques extérieures, est fabriqué en une céramique dont l'épaisseur permet de la retirer au moins partiellement, de manière à adapter la forme de l'élément de support. Pendant cette opération, un épaulement peut supporter la prothèse dentaire à installer, ce qui rétrécit l'élément de support et suit le bord de l'os de la mâchoire entourant l'implant.
