Definitions
- the invention relates to an inlay for a root canal of a tooth root of a tooth.
- Root tip resection is an operating technique introduced over a century ago for the treatment of periapical ophthalmos.
- a problem of this technique is the bacterial density retrograde closure of prisamputations ⁇ stumps in an existing orthograde root filling.
- plastic filling materials are used for the retrograde closure, all of which have the disadvantages of difficult processing, an individual source of error due to mixing processes and the risk of incomplete obturation of the entire retrograde treatment length.
- a rotationally symmetrical packing for introduction into a created by a rotating preparation instrument cavity in the root canal of a tooth which has a maximum length of 3 mm, so that it is suitable for introduction into a retrograde cavity of a root canal.
- the filling body and the cavity can have a conical shape.
- the filler may consist of titanium.
- This filler is only suitable for cavities which are formed with rotating repair instruments. He is also only partially suitable to effect a safe obturation of the root canal and thereby the stability of the
- the invention has for its object to provide an inlay of the type mentioned, with a safe obturation of a root canal with little effort and relatively quickly possible, the stability of the tooth root should be preserved.
- the inlay according to the invention consists of a body that tapers along its longitudinal axis (also called packing or inlay body) and can be inserted into a retrograde ultrasound prepared and shaped root canal. It can be prefabricated industrially for retrograde obturation with small tolerances, since it is adapted to the shape of the tips of the ultrasonic treatment instruments.
- the advantages of this inlay are the
- the inlay is fligbar to a shaped root in the tooth root, whereby on the one hand the tightness of the root filling is improved and on the other a seamless transition between root tip and inlay body is very easy , Thus, there are no attachment sites for Knochenverwach ⁇ sungen available, which could impact as to pins to bone loss.
- a defined position of the inlay body can be achieved by joining edge and collar.
- a size of the inlay body of 3 mm or more allows on the one hand the safe handling and processing of the inlay and on the other hand a high strength stability of the filled tooth root with uniform force absorption and distribution of or on the natural tooth substance at
- a filling material is arranged around the inlay body.
- Root canal filling compound optimally compacted when inserting the inlay.
- a preferred filling compound is cement, which is cheaply available in different variants.
- the inlay body is formed substantially rotationally symmetrical, whereby it is very easy to manufacture.
- care must be taken when inserting not on a special situation, whereby the treatment is accelerated.
- an oval root canal with appropriate preparation of the root tip of the inlay body may be oval shaped.
- the inlay body is easy to prepare and easy to use in the tooth root.
- An inlay body made of titanium causes a high so-called biocompatibility of the root canal filling, in other words, a good compatibility in the organism.
- the prefabrication of the inlays in several sizes which are preferably based on the outer shape of the tips of ultrasonic processing instruments, allows the cost-effective production of the inlays.
- a gap between the inside of a root canal and the inlay body (also called packing) allows to improve the adhesion of the
- Body in the root canal as can be arranged at these sites adhesion enhancing filling material.
- FIG. 2 shows an inlay with collar in a maxillary tooth
- FIG. 3 shows an inlay with a rounded collar
- FIG. 4 shows an inlay with a device for inserting the inlay
- FIG. 1 shows a tooth root 1 of a tooth Z with root canal 2 in the upper jaw 3.
- an access cavity 4 for the inlay I is created, through which the root tip resection takes place at the tooth root 1.
- the tooth root canal 2 is cleaned and brought into a regular, approximately conical shape, which corresponds to the external shape, in particular the tip of the ultrasound preparation instrument.
- the root canal 2 becomes retrograde with
- a body 6 (also called inlay body or filler) is pressed into the root canal 2. Excess cement 5 is pressed out through the gap 7 and then preferably removed.
- the inlay body 6 is made of one-piece titanium, such as pure titanium or a titanium alloy, or gold and is flush with the
- the inlay body 6 tapers from a larger cross-sectional area that lies after insertion at the end of the tooth root 2, to a smaller cross-sectional area located at the end of the interior of the tooth root 2 prepared and shaped retrograde by the ultrasonic treatment instrument.
- the larger cross-sectional area simultaneously forms the end of the inlay body 6 and represents a flat, circular surface.
- the inlay body 6 is formed with a length of 4 mm in total rotationally symmetrical about its longitudinal axis. In the case of oval root canals 2 and correspondingly oval preparation of the
- Root tip and oval shaped inlay body 6 can be made and used.
- the gap 7 results from the manual processing of the root canal 2 with the ultrasonic processing instrument, since its outer shape is the shape of the
- FIG. 2 shows an alternative embodiment for an inlay I.
- the inlay body 6 additionally has a circumferential, edged collar 8, which rests with its underside 8.2 just on a corresponding, incorporated in the tooth root 1 edge 9 and thus closes the gap 7 bakterien- tight.
- Root canal 2 in particular further into this, is likewise excluded.
- the internal pressure on the tooth root 1 is determined in principle by the contact pressure during the insertion of the inlay body 6 into the root canal 2.
- the contact pressure and thus also the internal pressure is limited by a collar 8 on the inlay body 6.
- the cement 5 is well compacted both in the gap 7 and in the remaining run of the root canal 2.
- the collar 8 is at least partially rounded, with its top 8.1 flat for a flat finish and its bottom 8.2 is rounded for inclusion in a corresponding with the rounding, machined into the tooth root 1 recess.
- a recess has the advantage that it easily fixes the inlay body 6 during insertion.
- the inlay bodies 6 are prefabricated in sizes and shapes corresponding to the external shape of an ultrasonic processing instrument.
- Inlay body 6 at its end with a larger cross-sectional area is possible without the risk of serious bone loss.
- what is essential is the flush termination of the edge of the inlay body 6 with the end of the root tip 1, in order to produce no deposit points for deposits or adhesions.
- the insertion of the inlay I can take place by way of example as in FIG. 4 with the aid of a wire 10 connected to the inlay body 6, which preferably consists of the same material as the inlay body 6.
- the wire 10 advantageously has a predetermined breaking point 11, at which the wire 10 is separated after Einset ⁇ zen. After the cement 5 has hardened, the remainder of the wire 10 remaining on the inlay body 6 is separated at a separation point 12 to a large extent. In this procedure, a remnant of the wire 10 remains on the inlay body 6, which does not affect the healing process.
