Definitions

  • the present invention is within the field of dentistry and more particularly relates to prefabricated dental inserts and methods to use such inserts, and moulds/inserts to form suitably shaped cavities to match prefabricated inserts.
  • Dental decay remains a very common health problem affecting the majority of people around the world. Repair materials such as mercury amalgam have largely ben replaced by synthetic composite materials, which however have limited life span and durability. Repair of dental decay such as caries may be broadly divided into direct and indirect repair methods. In direct repair methods the caries is removed and the cavity thus created is further cleaned and prepared. Thereafter a filling material, most often dental mercury amalgam or a plastic composite material is inserted into the prepared cavity. The filling, once hardened, is finished to smoothen out any rough edges and essentially create a surface similar in morphology to the original tooth. Live span of typical composite fillings is only about half of that of silver amalgam.
  • Indirect repair methods involve the use of prepared inserts, e.g. from ceramic material (porcelain or glass) or gold, that are cast in a mold made after the cavity which has been prepared as described above.
  • the insert which typically takes a couple of days to manufacture, is fastened in place with dental adhesive cement.
  • Indirect methods have been used for a long time and they provide stronger and longer- lasting inserts than can be provided by direct methods.
  • the indirect methods however, are significantly more expensive; both due to the cost of producing the inserts (i.e.
  • modified indirect methods include more effective methods to manufacture solid inserts, which allow the dentist himself to manufacture inserts in his own clinic.
  • the present inventor has earlier developed prefabricated inserts for use in a particularly shaped cavity that matches the size and shape of the insert.
  • the present invention provides new and improved methods and devices for repairing dental cavities, and in particular devices and methods to suitably shape cavities such that prefabricated inserts can be used, e.g. prefabricated ceramic inserts.
  • prefabricated inserts e.g. prefabricated ceramic inserts.
  • advantages from both direct and indirect methods are combined in a new method which can be seen as an intermediate between direct and indirect methods, increasing the durability of the inserted fillings.
  • the new approach makes it possible to use new materials that have not yet been introduced to dental use but are likely to be of great benefit for the durability of the insert.
  • New compounds can be produced so as to resemble more the natural composition of the tooth structure, as the invention allows use of materials that can be pre-shaped into inserts ("factory-made" inserts), and need not be able to be further shaped by the dentist.
  • the present invention provides for this purpose specially designed matrix inserts also referred to as preforms, which are used to press and cast a dental filling material inside a cleaned void.
  • a preform of suitable size is chosen which is close to the size of the cleaned void, i.e. the largest preform that will fit in the cleaned void.
  • cleaned void or clean void indicates herein that all caries damage has been removed.
  • the preform is selected from a set of different sized preforms (incrementally larger), followed by a prefabricated filling that matches the matrix preform insert.
  • the matrix preform insert is provided with a matrix jacket, that aids in holding the casting resin material within the void, and ensures that the preform is correctly located, in particular for repairing proximal cavities.
  • the form of the matrix jacket ensures that the permanent insert that follows always will sit correctly, that is, with the correct orientation, three-dimensionally.
  • the dental space is conveniently defined by three axes of the planes defined by basic planes defining the orientation of a tooth, the frontal (coronal) plane, the sagittal plane and the transverse (horizontal) plane.
  • the invention provides a method for repairing a proximal cavity in a tooth, in particular class II cavities, comprising the steps of removing decayed tooth tissue proximally in the tooth, placing in the bottom of the shaped void and on its side surfaces a portion of an approved dental filling material, placing in said void while the filling material is still fluid a matrix insert (preform) with an affixed shaped matrix jacket, wherein the jacket is shaped such that an outer surface of the matrix jacket faces and touches the proximal surface of the tooth adjacent to the void (the proximally

  • the invention provides a method suitable for repairing small proximal cavities, which comprises: removing decayed tooth tissue to form a clean shaped void; selecting a dental insert with a size matching the clean shaped void, wherein said dental insert comprises a removable jacket affixed to the proximal surface of the insert; placing a portion of a dental filling material in the clean shaped void; placing the selected dental insert in the filling material in the shaped void while the filling material is still fluid and soft, such that an outer surface of the matrix jacket faces the proximal surface of the tooth adjacent to the void, and the inner surface of the matrix jacket is in contact with the proximal surface of the tooth being repaired, around the clean shaped void;
  • a dental proximal insert having affixed to it a removable matrix jacket which is shaped to be substantially congruent and in contact with the proximal surface of the tooth adjacent to a shaped proximal void into which the insert is to be inserted.

  • the present invention is particularly suited for proximal cavities, which tend to be more problematic and are more common than buccal or lingual cavities. It is more difficult for a person to keep the proximal surfaces clean than the occlusal and lingual surfaces as the proximal surfaces are less accessible due to adjacent teeth; for the same reason of unaccessability, proximal cavities that may form due to caries are more difficult to repair than cavities in more accessible surfaces such as occlusal cavities.
  • the present invention further provides a solution to the general problem of applying desired and correct pressure in the contact area (between the proximal surface being repaired and the adjacent proximal surface) by shaping the matrix inserts such that the matrix insert will when inserted in a cast cavity, apply proper pressure to the adjacent tooth.

  • shaping the matrix inserts such that the matrix insert will when inserted in a cast cavity, apply proper pressure to the adjacent tooth.
  • the direct filling materials commonly used today tend to create gaps between the teeth in the contact point and fractures are most often seen in that area as well.
  • the present invention solves both of these problems by forming a firm contact point and by using stronger material which are possible to use in the pre-fabricated inserts as compared to inserts made or shaped by the dentist, that better copes with the strong occlusal forces.
  • the matrix insert of the present invention is as mentioned above equipped with a matrix jacket, that to certain extent provides the advantages of matrix strips, in addition to making it simpler to cast perfectly shaped and correctly located and oriented voids for matching prefabricated inserts, as discussed above.
  • the matrix jacket is generally shaped and dimensioned so that the inner surface of the jacket will sit congruent on the proximal surface of the tooth to be repaired and the thickness of the matrix jacket and outer surface is shaped so as to lie against the proximal surface of the adjacent tooth.
  • the term 'congruent' as used herein refers to that the shape of the inner surface of the jacket is suitably curved so as to substantially match curvature of a proximal tooth surface, such that the inner surface of the jacket will substantially follow the curvature/contours of the proximal surface of the tooth into which it is inserted. This ensures that the matrix jacket when pushed against the tooth sits firmly and cannot be rocked or tilted or generally improperly oriented.
  • the matrix jacket sitting in the correct location based on its fitted shape matching the tooth surface, holds the preform in the desired correct location and orientation, ensuring that the void (seat) created is correctly located and oriented.
  • the matching insert is preferably shaped with a width in the central part of the proximal surface/front surface 4 such that the insert will touch the neighbouring tooth and exert a suitable slight pressure thereon. This stabilizes the dental arch and minimizes and/or eliminates any unnecessary gap between the teeth, where food debris and bacteria can accumulate. This generally means that the most proximal point of the proximal surface of the insert essentially extends as far towards the neighbouring tooth, as the proximal outer surface of the matrix jacket. When the matrix insert with matrix jacket is removed, and the insert later inserted in the void, it will thus extend to the proximal contact point of the adjacent tooth, minimizing or eliminating a proximal gap between the insert and the adjacent tooth as described above.
  • the insert is shaped so as to leave a slight groove between the proximal surface 4 and the surrounding edges of the cast void (bottom edge and/or parts of the side edges), meaning that the proximal surface of the insert is slightly smaller than the corresponding surface on the matrix insert.
  • the groove will be filled with the second filling material, to ensure a smooth continuous transition between the insert and tooth void edges.
  • a matrix band can be used, which is inserted between the tooth and the neighbouring tooth before the pre-fabricated insert is cemented in place, the matrix band avoiding excess of the second filling material (cement material) to protrude from the edges.
  • the method of the invention is described in further detail herein.
  • the cavity in need of repair is first prepared by removing decayed tissue, such as typically with a conventional dental drill.
  • the dentist prefers to remove as little healthy tooth tissue as possible, while still being able to accommodate and fasten a durable filling/repair material.
  • the dentist needs only to remove the caries from the tooth as recommended.
  • the inserts are preferably provided in different sizes, as further discussed herein below.
