Definitions
- the invention relates to a method, a device and a means for removing caries in a cavity.
- a common measure to remove tooth decay is to remove it by cutting, e.g. with rotating or oscillating tools, which are held in a handpiece by means of a shaft and are moved against the point to be machined during operation. If the caries is deep, this measure is problematic for several reasons. On the one hand, a large access opening is required to allow the dentist to look into the cavity so that he is able to determine where caries is located and whether the caries has been completely removed. Visually checking this is difficult and therefore there is a risk that the caries will be insufficiently removed or healthy tooth structure will be removed. In addition, the caries can have marble spatial shapes, so that it is necessary to use the tool to remove adjacent healthy zones of the tooth structure in order to be able to completely remove the caries.
- the invention is based on the object of finding a method and a device of the present types which make it possible to process surface areas in a targeted manner.
- an agent which contains a caries-dissolving substance and / or solid particles, which is introduced into the cavity and is subjected to vibrations by an oscillating part inserted into the agent in the cavity.
- This will make the effectiveness of Improved in several ways.
- the penetration of the agent into the cavity and also into small gaps is improved, so that it can be brought into a cavity and is effective even in places that are difficult to access.
- the effectiveness of the agent is improved and intensified by the vibrations. This applies both to the alternative in which the agent contains a caries-dissolving substance and the one in which it contains solid particles.
- the improved effectiveness is due to the fact that the effectiveness of the caries-releasing substance is improved by the vibrations.
- the solid particles are accelerated by the vibrations, the vibration transmission extending to the periphery of the agent due to the existing mass of the agent, and the particles located there abutting the cavity-wall of the tooth and in particular removing the tissue infected with caries which is softer than the healthy tissue.
- the removal from healthy tissue, which is harder, is only very slight. This is advantageous because the healthy tissue should be protected.
- the method described above is suitable both in a closed system in which the cavity is covered and in an open system in which the cavity is not covered.
- the latter is particularly advantageous because it is a very simple method in which it is not necessary to provide coverage, which is of course associated with a corresponding outlay.
- the open system is designed for processing situations in which the cavity is open on the top. It is of course also possible to use this method in a closed system in which the opening of the cavity or access cavity is closed.
- the method according to claim 2 is intended for a closed system.
- the desired improvement in the effectiveness of the agent is achieved in that the agent is fed to the cavity continuously, at least temporarily, ie in a flowing movement.
- the flow improves the contact between the agent and the cavity wall.
- the agent instead of a caries-dissolving substance contains holding particles which, owing to the flow of the agent, are able to remove the relatively soft tissue affected by caries.
- this method also protects the healthy tissue.
- claims 3 and 4 improve the effectiveness of the agent.
- the particles are abrasive on their surface and in the second case by the fact that the particles, due to their mutual contact, directly transmit the vibrations and the resulting dimensional forces against each other and therefore the particles located at the pereferie are efficient.
- the agent according to the invention which is suitable for mechanically removing body tissue, in particular caries.
- the agent has to be set in motion in the cavity, so that the solid particles contained therein come into frictional contact or impact contact with the wall of the cavity and thereby remove the body tissue, in particular caries.
- the movement can be realized by causing the agent to vibrate or to flow.
- the agent can be improved by adding a caries-releasing substance.
- the agent is effective not only mechanically but also chemically, the chemical effectiveness being independent of the flow and also being active in the case of a non-flowing agent.
- the flow however, also increases the chemical effectiveness.
- a further improvement of the agent is achieved if the particles are abrasive. This can be achieved by particles that consist of an abrasive material or have an abrasive material on their surface, for example equipped with abrasive grains or coated.
- Figure 1 shows a tooth in vertical section during treatment with the first method according to the invention in the open system.
- Fig. 2 shows a detail of Figure 1 in an enlarged view.
- FIG. 3 shows a tooth in vertical section during the removal of caries by the second method according to the invention in the closed system
- the tooth is located between two adjacent teeth 2, 3, the tooth 1 having deep caries 4 which can emerge through a tapered connecting zone 4a on one side or on the upper side of the chewing surface of tooth 1.
- the connection zone 4a is arranged proximally and is therefore inaccessible from this side.
- the method is in a process state in which the carious site has been broken in from the occlusal or has been prepared conventionally, e.g. with a rotating tool so that there is an occlusal access opening 6 here.
- the cross-sectional dimension of the access opening 6 is significantly smaller than the cross-sectional dimension of the cavity 7 located underneath.
- caries 4 are still present, the layer thickness of which is shown relatively thin, but can also be significantly thicker , in particular when the method according to the invention is used in the area of a natural cavity without prepreparation.
- an agent 11 of liquid or pulpy consistency for example gel consistency, which contains a substance that dissolves caries and is available in a reduced-size storage container 12 from which the agent 11 can be introduced into the cavity 7 , for example by means of a cannula 12a which has an outlet opening 12b for the agent 11 at its free end, in particular at the end of an angled cannula leg 12c from which the agent 11th can be conveyed out, for example by manually compressing the storage container 12 made of elastic material, in particular plastic.
- a cannula 12a which has an outlet opening 12b for the agent 11 at its free end, in particular at the end of an angled cannula leg 12c from which the agent 11th can be conveyed out, for example by manually compressing the storage container 12 made of elastic material, in particular plastic.
- the caries releasing substance can e.g. Sodium hypochlorite in combination with amino acid at a strongly basic pH.
- the agent 11 also contains solid or hard particles 13, the size of which can be the same or different and e.g. can be about 0.001 mm to about 0.1 mm, in particular about 0.1 mm.
- the particles 13, which are e.g. can be a mixed powder, are preferably abrasive on their surface.
- Such abrasive materials are e.g. Aluminum oxides, silicon carbides, quartz, glass, salts and the like.
- Abrasively coated particles are also suitable, e.g. made of plastic or glass.
- the particles 13 can have an irregular shape or spherical shape.
- a vibrating body 14 is provided, the cross-sectional size of which is smaller than the access opening 6 and which is located at the end of a preferably angularly shaped or arranged shaft 15, which can be set into vibrations by a vibration generator 16, preferably in the sound or ultrasound range is.
- the cross-sectional size of the vibrating body 14 can be equal to or greater than the cross-sectional size of the shaft 15.
- the vibrating body 14 is thickened with respect to the shaft 15 and is preferably spherical in shape with or without lamellae.
- An elongated or rod-shaped handpiece 18 is used to hold the tool 17 thus formed, in which a handpiece shaft 19 is mounted such that it can vibrate and can be set in vibration by a vibration generator 16 arranged in the handpiece 18.
- the vibration generator 16 or vibration drive generates short-stroke vibrations in the sense of a vibration with a frequency preferably in the sound or ultrasound range, wherein the vibrations or amplitudes can be elliptical or circular, the amplitude direction preferably changing spatially, that is to say on all sides.
- the drive power of the vibration generator 16 is preferably variable and thus adaptable to different working conditions.
- a one-piece member 22 is provided, which is preferably arranged on the handpiece 18, in particular on its outer surface, and is there, for example, displaceably mounted.
- the handpiece 18 consists of a handle piece 18a and a rear connecting part 18b, which are detachably connected to one another by a quick coupling, here a plug / rotary coupling.
- the coupling K has a cylindrical plug pin 18c here on the connecting part 18b, onto which the other part can be plugged with a plug-in recess 18d and can be secured by a latching device (not shown) which can be pushed over.
- the tool shaft 15 is preferably releasably connected to the handpiece shaft 19.
- a screw connection can be used for this.
- a switch (not shown) is provided for switching on the vibration generator 16, e.g. on the handpiece 18 or removed as a foot switch.
- the vibration or oscillation drive has a frequency of approximately 4 kHz to 8 kHz, approximately preferably 6 kHz, with an amplitude of the preferably spatial vibrations of approximately 0.05 mm in the area of the tool 17 or oscillating body 14 up to 0.2 mm, in particular 0.1 mm.
- the control device formed in this way can be designed in such a way that it enables the oscillation power to be set in the aforementioned range or also to be set beyond the range, so that, if appropriate, considerably larger amplitudes can be set, e.g. Amplitudes up to about 0.5 mm in size.
- the agent 11 is introduced into the cavity or flushed in and filled.
- the means 11 are then activated by the oscillating body 14, which, owing to the above-described tool shape, is introduced and switched on with the handpiece 18 through the mouth opening into the means 11 in the cavity 7 and is switched on.
- the means 11 is set in vibration and its effect is accelerated and its performance in resolving caries is increased. This is mainly the chemical effectiveness of the caries-dissolving substance.
- the agent 11 contains particles 13, it also becomes physically active. This is due to the fact that the vibrational energy is converted into kinetic energy for accelerating the particles 13 and these collide with the carious substance and thereby remove it.
- the particles 13 are particularly efficiently accelerated and swirled when the number of particles 13 on average 11 is so large that the particles abut one another and the vibration is transmitted directly. This is shown in FIG. 2, which shows the cross-sectional size of the particles 13, which are identical or different, in an adjacent position. Between the particles 13 can however, there are also means 11.
- the active caries removal can also take place by an abrasive coating of the particles 13.
- the tissue infected by caries 4 is softer than healthy tissue, the carious tissue in particular is removed and removed in the method according to the invention. In contrast, the healthy tissue is spared.
- the method according to the invention not only removes the carious tissue, but also advantageously prepares the composite surfaces of the opturation and / or opturates the cavity 7.
- the method according to the invention can be repeated. Between the individual process sections or according to the process according to the invention, the cavity 7 is emptied and cleaned, e.g. by suction, by rinsing, blowing out and the like.
- the access opening 6 can be closed by a cover 25 fastened to the tool shank 15, which is a flange-shaped closure part, e.g. can act in the form of an externally round disk with a central hole 26 with which it sits on the tool shaft 15 and is fixed, e.g. by clamping voltage.
- the cover 25 or the disk are preferably made of elastic material such as plastic or rubber, so that the free edge of the disk is able to adapt to the tooth surface.
- the disk is preferably conical or frustoconical, as a result of which it is stabilized against bending.
- the cavity 7 can be closed, and therefore such a tool 17 is also suitable for treating a cavity which is open on the side or on the underside. Even in such positions, the agent 11 cannot automatically run out of the cavity 7 when it is covered.
- a paste 11 with a pulpy consistency or a gel-shaped paste 11 which, however, is also suitable for a position according to FIG. 1.
- the cover 25 can be freely displaceable in the longitudinal direction of the tool shank 15 in order to adjust the depth of penetration of the tool or vibrating body 14 in the tooth. It is also advantageous to arrange the cover 25 on the tool shank 15 so as to be displaceable and optionally lockable. This can be achieved by clamping tension with which the edge of the hole 26 presses against the tool shank 15.
- the caries 4 can optionally also be removed in the connecting zone 4a, which is the case in the present exemplary embodiment approximal opens.
- Such openings are covered on the outside before the introduction of the agent 11 into the cavity 7, for example by means of a bandage or a closure sheet 27 (metal matrix) which can be fixed in the intermediate tooth region, for example by means of a wedge 28.
- the caries 4 are removed, on the one hand, in the closed system and, on the other hand, with at least temporarily continuous flow of the agent 11 and / or also by activation of the agent 11 due to vibrations.
- the main parts of the device 30 are a conveying device 31 for conveying the medium 11 from a storage container 32 to a rod-shaped connecting part 33 through a feed line 34, in which a pump 35 is located.
- a discharge line 36 extends from the connection part 33 to a collecting container 37.
- the supply line 34 and the discharge line 36 open out on the free end face 38 of the connection part 33, whereby they preferably penetrate the latter axially.
- the connecting part 33 can sit in a sleeve 33a or form this sleeve 33a, which can be inserted directly into the access opening 6 or can be inserted into a second connecting sleeve 39, which consists of elastic material, in particular rubber or plastic, and can be inserted and fixed in the access opening 6 is, preferably by radial clamping tension, and in particular has an outer flange 41 which rests on the outside of tooth 1 and prevents it from slipping into tooth 1.
- the tooth opening can be adapted to the connecting piece 39 by standardized preparation. In the case of an individual access cavity, the seal is made using a provisional filling material (e.g. a light-polymerized "provisional" plastic).
- the connecting part 33 or the first connecting sleeve 33a conical towards its free end and to make the second connecting sleeve 39 conical on the inside in order to facilitate the connection and also to bring about a clamping connection when the connector is inserted.
- the connecting sleeve 33a or the connecting part 33 can preferably also have a flange 33b to limit the insertion depth.
- the first connecting sleeve 33a or the connecting part 33 is provided for the direct engagement in the access opening 6, it is advantageous to form it from an elastic material such as rubber or plastic, as a result of which the seal and the press fit are improved.
- the pump 35 or a downstream system for example a Bernoulli nozzle, flushes or sucks the liquid in rapid alternation under pressure. This alternating load movement activates the solution or reinforces its effect through imploding cavitation bubbles.
- the connecting part 33 is connected to the access opening 6 in the manner described above and the agent 11 is conveyed into the cavity 7, several measures being available in this method to improve the effectiveness of the agent and its performance.
- the agent 11 contains only the caries-dissolving substance, the effectiveness and performance can be increased by the agent 11 being conveyed continuously or intermittently or at intervals, with a continuous movement and flow taking place during the conveying, which affects the effectiveness of the agent 11 improved.
- the agent 11 contains only particles 13, the agent 11 is continuously conveyed, the particles 13 being mixed during the flow, hitting the wall of the cavity 7 and removing the caries 4 by impact.
- the agent 11 contains the caries-dissolving substance and the particles, the effectiveness can be multiplied accordingly by conveying.
- the effectiveness can be increased by vibrating the connecting part 33 and / or the first connecting sleeve 33a or the feed line 34 and / or the discharge line 36 with a vibrating part 14a, which transmit the vibrations to the particles and the effectiveness through increase the vibration effect of the particles 13.
- the effectiveness of the agent 11 can be increased by varying the pressure in the agent 11.
- the pump 35 for example in that it is formed by a lifting pump piston which increases the pressure during the forward stroke of the piston and reduces it during the return stroke or even generates a negative pressure.
- Similar pressure differences can also be achieved by means of a rotary piston, which functions after the Wankel rotary piston, as a conveying means for the pump 35. It can thus be seen that the effectiveness of the agent 11 can be changed by varying its composition and can be forced by taking the above-described additional measures.
- the agent 11 While the agent 11 is being conveyed by the conveying device 31, the agent 11 is mixed and swirled in the cavity 7, the caries-dissolving substance in contact with the wall of the cavity 7 and / or the particles 13 located there dissolving the caries 4 or remove.
- An example of the flow taking place is illustrated by arrows in FIG. 3.
- the medium 11 conveyed into the cavity 7 flows through the discharge line 36 into the collecting container 37.
- the opening of the line 36 can be secured by a sieve against the particles 13 flowing away from the cavity 7.
- the cavity 7 is cleaned after the caries 4 has been detached and / or machined, which can be done by rinsing and / or blowing out.
- the cavity 7 can then be closed individually using a suitable filling material.
- the free surface shape of the filling material in the area of the access opening 6 can be adapted by the shape of a previously made impression.
