Definitions

  • the present invention relates to an implant provided with attachment and hole-insert parts which have surfaces with different degrees of finishing and/or degrees of roughness and/or porosities. It also relates to a method for establishing different degrees of finishing and/or degrees of machining and/or porosities on outer surfaces of an implant with attachment and hole-insert parts. The invention also relates to an arrangement for providing a range of implants which are optimized for different dental situations.
  • a first porosity can be present at one end of the zone and can condense or decrease towards the other end of the zone.
  • the zone in question will be able to extend along at least the greater part of the longitudinal extent of the implant.
  • a porosity of zero, or close to zero will be present on the surface at the attachment part of the implant, i.e. the degree of finishing and/or degree of machining is high on this surface. Thereafter, i.e.
  • the porosity will start with a low value and will increase gradually in the longitudinal direction of the implant towards the tip of the implant, or vice versa.
  • the increase in the porosity of the implant along the longitudinal extent of the implant can be made linear or progressive.
  • Implants will alternatively be able to be provided with two or more such marked zones where the porosity is linearly or progressively increasing or decreasing from one end of the respective zone to the other end of the zone.
  • the porosity or the porosities will be able to increase linearly or progressively in the circumferential directions of the implant.
  • the porosities will be able to form marked islands on the outer surfaces of the implant, which islands are thus situated on finished and/or machined surfaces.
  • the porosities are also intended to be used as depots for bone-growth-stimulating or bone-growth-promoting agents, and the movement of these agents from the depots to the surrounding bone must be controlled and varied according to the different dental situations
  • the porosities must therefore be able to mirror the tooth bone structure and provide optimum insertion and anchoring functions for the implant in the respective bone and optimum functions concerning the release of the bone-growth-stimulating agents.
  • the feature which can principally be regarded as characterizing an implant according to the invention is that the surfaces are provided with at least one zone in which the degree of finishing and/or the degree of roughness and/or the porosity is continuously changed.
  • the implant has a single zone with continuously decreasing or increasing porosity.
  • Some of the surface or surfaces, for example the surface of the attachment part, can be formed with a low, minimal porosity.
  • two or more zones can be arranged along the longitudinal and/or circumferential directions of the implant. In a preferred embodiment, each zone will take up a longitudinal or circumferential value which is 5% or more of the respective extent.
  • the invention is preferably used in connection with implants having an outer thread or threads.
  • the feature which can principally be regarded as characterizing a method according to the invention is that the implant is applied wholly or partially in or near an electrolyte, and that the implant is subjected to cooling which is preferably substantial and that voltage is applied to an anode and cathode arrangement where the implant is arranged so that a current produced by the voltage is passed through the implant to establish said porosity.
  • Liquid nitrogen can be used for cooling, and the implant can be connected to an anode included in the anode and cathode arrangement at a boundary surface in the container. The anode is situated in the nitrogen in the container and the cooling of the anode effected by the nitrogen is transmitted to the implant by means of its mechanical contact with the anode.
  • the implant is immersed wholly or partially in electrolyte and a continuous transition zone is obtained by the fact that, in parts of the implant not immersed, the electrolyte is taken up in a decreasing amount along the height of the implant and by the fact that the decreasing amount gives rise to the continuous change in the porosity.
  • parts of the implant can be masked so that the electrolyte is prevented from gaining access to the masked portions and is thus prevented from forming porosities. Different sizes of porosities are determined inter alia by means of the electrolyte composition and/or changes in voltage and/or current.
  • the novel arrangement is characterized mainly by the fact that a number of implants are provided with different continuously decreasing changes in porosity in one or more zones and by the fact that the different implants in the range can be used to achieve optimum solutions to different dental situations.
  • FIG. 1 is a diagram showing the porosity or roughness as a function of the implant length L, and a curve indicating a porosity continuously increasing towards one end of the implant,
  • FIG. 2 is a side view showing an implant related to the diagram in FIG. 1, and where the implant has a certain degree of finishing on its left part (attachment part) and where the porosity or roughness increases as the curve rises in FIG. 1 towards the free end of the implant,
  • FIG. 3 is a diagram showing voltage and current parameters in an applied electrochemical process
  • FIG. 4 is a side view and schematic representation showing an electrolyte used in the electrochemical process, and an anode and cathode arrangement arranged in this,
  • FIG. 5 is a schematic representation, enlarged in relation to FIG. 4, showing the application of the implant in relation to a suitable cooling unit and electrolyte, and where the implant has been masked on parts of its length,
  • FIG. 6 is a side view showing another masking in relation to the example in FIG. 5,
  • FIG. 7 is a side view showing the implant with a number of different zones with continuously decreasing porosity and zones of very low porosity
  • FIG. 8 is a vertical section showing decreasing zones in the circumferential direction of the implant
  • FIG. 9 is a vertical section showing the application of the implant to an anode part which extends into the cooling unit/container unit according to FIG. 4, and where the porosity increases towards the free or lower end of the implant,
  • FIG. 10 is a vertical section/vertical view showing a further design of the connection of the implant to the cooling unit and maskings for establishing substantial porosity-free zones
  • FIG. 11 is a vertical section/vertical view showing a reverse application to the cooling unit compared to the embodiment according to FIG. 10,
  • FIG. 12 is a vertical section/vertical view showing the application of the implant to the cooling unit with the implant lying in such a way that a varied porosity is obtained in the circumferential direction of the implant, and
  • FIG. 13 shows an example of a dental implant produced according to the invention.
  • the varying or continuously modified porosity in the zone or zones concerned can be obtained in different ways.
  • an electrochemical method is preferably used which can be of a type known per se.
  • the electrochemical method which is described in the Swedish patent applications 9901971-3 and 9901974-7 is highly suitable for use in this context, reference is made to these patent applications which were filed by the same applicant as that of the present patent application.
  • the oxide layer on the surface of the implant can be formed and varied by adjusting various parameters in the process, which parameters can include the composition of the electrolyte, the voltage and current in the anode and cathode arrangement used, the electrode geometry, the treatment time, etc.
  • the implant requires to be applied to and acted on by the electrolyte in the manner described below.
  • the electrochemical process will not be described in detail here, and instead reference is made to said patent applications
  • a curve 1 indicates a continuously modified roughness/porosity along the length of an implant.
  • the change here is assumed to be obtained along a zone or zones of the implant.
  • a low degree of roughness/porosity is used at one end of the implant, which low degree of roughness can have a value of 0.7 ⁇ m.
  • the roughness in this case changes distinctly to a value of 1.0 ⁇ M, for example.
  • the roughness increases in the zone or zones in question up to a value of 1.5 ⁇ m. This increase represents a continuous change and can be linear and can have a progressiveness in accordance with the line of the curve 1 .
  • the implant shown diagrammatically in FIG. 2 is related to the diagram according to FIG. 1 such that a distance A on the implant corresponds to the distance 1 in the diagram.
  • the length or distance B corresponds to the curve length 1 to 1 ′.
  • the distance A represents an attachment part 2 for a spacer element
  • the distance B represents a hole-insert part 3 of an implant 4 .
  • the implant 4 has a design characteristic to the invention. In this case, the distances A and B form two different zones in which there is a continuous or progressive roughness/porosity.
  • the attachment part 2 can have less roughness/porosity along its length or a roughness/porosity which is lowest at an end surface 2 a and increases gradually towards the bottom surface 2 a′.
  • the lower degree of roughness/porosity established at the end surface 2 a is indicated by 2 b, while the gently increasing roughness/porosity at the bottom surface 2 a′ is indicated by 2 c.
  • the outer surface 2 d can be considered to have a low and gently increasing roughness/porosity viewed from the end surface 2 a.
  • the degree of roughness/porosity can be varied, and in one illustrative embodiment the outer surface 2 d can be entirely without porosity markings or can have extremely low porosity, i.e. the outer surface 2 d is very finely machined.
  • the extent B of the implant is arranged such that there is a single zone, in which zone therefore a low roughness/porosity is present at the upper end 3 a of the hole-insert part 3 and a relatively high (cf. FIG. 1) roughness/porosity is present at the end 3 b of the hole-insert part.
  • FIG. 3 shows typical current and voltage values in the electrochemical process (see also said Swedish patent applications).
  • a current value of 0.2 ampere is used in this case, and the voltage value can extend up to a level of 300 volts, for example.
  • the current curve is indicated by I and the voltage curve by U.
  • the horizontal axis represents a time axis t.
  • a certain spark formation occurs in the area 5 on the voltage curve U. The spark formation occurs along the whole of the implant surface and gives rise to pore formation and increased surface roughness.
  • FIG. 4 is a diagrammatic representation showing an electrolyte 15 used in the electrochemical process, and an anode and cathode arrangement applied in the latter.
  • the anode 8 which can be formed by the implant itself or can consist of a part which is mechanically coupled to the implant 9 is connected to the positive potential 10 of an energy source 11 .
  • the positive connection of the anode and cathode arrangement is indicated by 13 .
  • the negative potential 12 of the energy source is correspondingly connected to the cathode 14 of the anode and cathode arrangement.
  • the lower parts 9 a of the implant are dipped in the electrolyte 15 .
  • Capillary and other suction and evaporation phenomena mean that electrolyte is taken up in decreasing quantity upwards and along the outer surface parts 9 b of the implant which are situated above the immersed parts 9 a of the implant.
  • the effect of this is that the immersed parts 9 a are exposed to a chemical treatment which gives a greater porosity than the porosity of those parts 9 b which are situated above the parts 9 a.
  • This has the effect that a zone is obtained on the parts 9 b where the porosity is continuously modified or decreases in the upward direction.
  • FIG. 4 shows a cooling arrangement 6 which in this case consists of a container 6 a for liquid nitrogen 7 .
  • the anode 8 of the anode and cathode arrangement is arranged in or extends through the interior 8 of the container and is in this way subjected to a cooling function exerted by the liquid nitrogen.
  • the position of the zone can be changed with the aid of the degree of immersion of the implant in the electrolyte 15 .
  • the degree of immersion can be adjusted in the directions of the arrows 16 .
  • the suction forces along the surface 9 c of the implant mean greater electrolyte accumulation 15 a at the lower parts 9 d of the implant than at parts 9 b which are situated higher up.
  • the electrolyte can thus influence the implant with a greater amount of electrolyte at said lower parts 9 d than at the parts 9 c situated higher up, which also indicates said continuous or progressive change or reduction of the porosity towards the upper parts of the implant.
  • the maskings can consist of tube-shaped parts 17 , 18 of Teflon, latex, etc. Alternatively, lacquers can be used.
  • the maskings are intended to prevent porosity occurring on the masked parts during the electrochemical process.
  • the tube part 17 or the like masks an area 9 f which is situated under the spacer attachment part 2 d.
  • the last-mentioned part is in turn masked by the tube or the lacquer 18 .
  • Said areas 9 f and 2 d therefore have a very low porosity or no porosity at all, depending on previous treatment or working.
  • the masking function it is also possible to use the masking function to form islands or areas 9 g, 9 b which extend across parts of the surfaces of the implant.
  • these areas 9 g, 9 h the porosity continuously changes from the lower parts of the implant in the direction towards the upper parts of the implant.
  • the masking has been done with a tube, a lacquer, etc. 19 leaving the surface open for said areas.
  • the implant 9 d is thus given a porosity which continuously increases or changes from the lower part up towards the masking 19 , which increase or change merges into said areas 9 g, 9 h.
  • masking functions can thus be used, and during the total process of coating the implant 4 with one or more zones of decreasing or increasing porosity, the positions of the maskings can be rearranged or changed. According to FIG. 7, several zones C, D and E can be established along the longitudinal extent or height of the implant.
  • each zone for example the zone 19 , has a greater porosity at the end 19 a than at the end 19 b and the porosity continuously decreases within the zone.
  • FIG. 9 shows in more detail the mechanical connection between the implant 4 and the anode part 8 according to FIG. 4
  • the anode part 8 can have a recess for the spacer attachment part 2 d of the implant, which recess is indicated by 8 a.
  • the size of the recess is adapted to the spacer attachment part so that the implant is secured in the anode part 8 .
  • This arrangement also provides masking for the outer surface 2 d of the part 2 . It will be evident from this embodiment that a large mechanical contact surface is present between the implant and the anode 8 , which contact surface is established by means of the top surface 2 a of the implant and the bottom surface 8 a′ of the recess 8 a.
  • the implant and the anode must be pressed against each other with forces F and F′ respectively.
  • said porosity is established at the lower parts of the implant, while at the same time the implant is exposed to a very great cooling effect from the liquid nitrogen in the container 6 a.
  • the cooling function is thus established via the bottom part 6 b of the cooling arrangement.
  • the anode part 8 and the bottom part 6 b can be sealed by means of a sealing ring 21 or the like.
  • FIG. 10 shows another means of connection of the implant 4 to the anode part 8 which in this case does not have the recess (cf. 8 a ) indicated in FIG. 9.

  • the implant 4 is provided with masks 25 , 26 of the type indicated above.
  • a characteristic of the zones is that the porosity is greatest at the bottom of each zone and decreases upwards to the spacer attachment part 2 .
  • the implant is turned around compared to the case in FIG. 10.
  • the free end surface 9 d′ of the implant is in this case secured in the recess 8 a of the anode in the same way as in FIG. 10.
  • the anode in this case can comprise a recess in the same way as in FIG. 9, which recess is adapted to the tip (free end) of the implant 4 .
  • the implant, the anode, etc. are displaceable in the direction of the arrows 25 in order to provide for immersion in the electrolyte 15 to a greater or lesser extent.
  • the coarse porosity is established at the end surface 2 a of the spacer attachment part 2 and decreases towards the tree end 9 d′ of the implant. In this case there is therefore only one zone.
  • the implant is in principle arranged horizontally in relation to the surface of the electrolyte 15 .
  • the anode 8 has a recess 8 a in which the spacer attachment part 2 is connected.
  • the thus horizontally arranged implant can be immersed to a greater or lesser extent in the electrolyte 15 in the directions of the arrows 26 . In this way, porosity of different sizes is present about the circumferential direction of the implant, cf. FIG. 8.
  • the implant itself can only form the anode in said anode and cathode arrangement.
  • the implant extends through the bottom part 6 b of the container 6 according to the example above.
  • the outer surfaces of the hole-insert part have been indicated by 3 a′ and 3 b′.
  • the degrees of porosity have been symbolized by 2 f and 2 g, respectively.
  • the length or height of the implant is indicated by H.
  • a marked or extended zone, for example one of zones C, D or E, means that the extent of the zone in the direction H of the implant must be at least 5% of the value of H.
  • the decreasing porosity or porosities in the circumferential direction will assume a value of at least 5% of the total circumference 2 h in said extended or marked zone.
  • a first thread of a cylindrical portion is indicated by 4 ′ and a thread on the conical tipped part of the implant is indicated by 4 ′′.
  • the degree of immersion of the implant in the electrolyte 15 depends on where and how long the marked or extended zone for the continuously changed porosity is to be and/or on the degree of masking of the implant. According to the invention, it is also possible to provide a range of implants which are basically the same, but with different porosity changes within one or more marked zones, different zones, etc.
  • implants can have different numbers of marked zones with different porosity changes, i.e. changes with different sizes of the porosities and different changes of these porosities. With such a range, it is possible to choose the implant which in the given dental situation is considered to give the best result or the most optimum result in said dental situation. The choice can be made on the basis of practical experience or by assigning different dental situations to different implants.
  • FIG. 13 shows an example of a dental implant of a type known per se (Blangemark System®) which has been provided with a surface structure according to the invention
  • the implant is made of titanium and has a machined surface.
  • the machined surface remains on the spacer attachment part 2 , the flange, while the threaded part, the hole-insert part 3 , has a roughness/porosity produced according to the above method and continuously decreasing along the length of the implant from the flange.
  • the figure also shows two enlargements taken on the threaded part, and on the curved part at the spacer attachment part, where the machined main surface has been acted on to a lesser extent by the electrolyte treatment.
