Description

IMPLANT SYSTEM WITH HEXAGONAL SUPPORT FIELD OF THE INVENTION This invention relates to the field of dentistry and in particular it relates to a dental implant assembly having a support to which a dental implant can be fixed.

BACKGROUND OF THE INVENTION Dental implants have been known, and used, at least since the 1930s; see for example the pa + en + e of the United States 5,3.12,254 by Joel L. Rosenlicht.

See also U.S. Patent 5,145,371 to Lars Jornous, which deals with the osseointegration method for integrating a dental implant into the jaw of a patient; the description of each of these patents is hereby incorporated > or reference in this specification. Denial implants are moderately expensive. It often costs three to four thousand dollars to implant a tooth in a patient's mouth. One of the reasons for this considerable cost is the multitude of steps required by the implant procedure.

These steps will be described below according to the prior art with reference to the Nobelpharma PRI 385 catalog. 94. 03, second edition (published by Nobel pharma AB, PO Box 5190, -402 26 Goteborg, uecia). In the first step of the procedure according to the prior art, an implant or "M a installation" was acquired; see, for example, page 7 of the Nobel phapna catalog and the reference to titanium fixed installations of 3.75 RMN and 4. 0 inrn illustrated on such page. The installation thus acquired must then be placed in a "design team for the installation of fixed installations", which is shown on page 22 of the catalog of Nobe 1 pha i 'm. Once the fi ne installation is available in the "instrument system ...", a "fixed installation frame" is then fixed to the fixed installation by means of a wrench and a screwdriver. The "installation mount f ja" devices are shown on page 22 of the Nobelpharrna catalog. The instruments for the installation of the fixed installation of fi a are also shown on page 22 of the Nobelpharrna catalog (see part 17 of the key and part 19 of the screwdriver). After that, a "connection to the manual piece in con angulo" (see part 11 on page 22 of the Nobelpharrna catalog) or a manual piece (see page 31 of the Nobelpharma catalog); and the implant assembly can then be fitted to the bone of the patient's jaw. After that, the installation frame is moved to the fi ve installation. After that, a cover screw (see page 9 of the Nobelpharm catalog) is inserted into the fi ve installation. After that, the surgical site is left to heal for about 3 to about 6 months. See for example Branernark / Zarb / AlbereH sson: "Tissue Tntograted Prostheses" (Oumtessence Books, 1985). After the separation period, the implant is exposed by surgical procedures and the cover screw is removed. After that, a healing support (see page 39 of the Nobelpharrna catalog) is fixed to the fixed installation. A is generally in place for about two to about three weeks, depending on how the patient's tissue has healed. After that, the healing support is then removed and the implant support is then fixed to the fixed installation. The type of implant support to be used will depend on the patient's requirements. In this way, for example, and referring to pages 38 and 39 of the Nobelpharrna catalog, a normal support, a support of "EsthetiCone", a support of "CeraOne", a "Sphere Fixation", a "can be used". Angled support ", and similar. After that, the desired prosthesis is formulated by conventional means. Once the prosthesis has been prepared, it is placed in the patient's mouth attached to the implant. It should be evident that this method according to the prior art requires a number of instruments and prosthetic parts, many trips from the patient to the dentist and several surgical procedures. The procedure is not only tedious and expensive, but each surgical procedure introduces a certain element of risk, pain and suffering. It is therefore an object of the present invention to provide a new method for implanting a novel dental prosthesis in the mouth of a patient that is considerably less expensive, safer and less time-consuming than the procedures and implants according to the prior art. It is another object of this invention to provide a novel dental support. It is still another object of this invention to provide a novel carrier pair such a support. It is still another object of this invention to provide a novel scar tissue that can be used with the support of this invention. It is still another object of this invention to provide a novel system of fixation with 0-rings to hold the dentures inside the mouth of the patient. It is still another object of this invention to provide a novel gold cylinder that can be used with the support of this invention. It is still another object of this invention to provide a novel fastening system with a bar fastener for holding a denture inside the mouth of a patient. It is still another object of this invention to provide a novel removable fixed bridge supported by an implant. It is still another object of this invention to provide a novel gold collet device for use with the implant holder of this invention. It is still another object of this invention to provide a method for fixing a prosthesis to a patient which is considerably more accurate than the procedures of a prior art.

BRIEF DESCRIPTION OF THE INVENTION In accordance with this invention, a novel support is provided which is preferably an integrally configured sleeve-shaped element having a lower portion and an upper portion. The exterior of the lower portion of the support contains an annular groove disposed between the base and the main, substantially polygonal portion of the support body. The support sleeve preferably contains rounded corners that are compatible with the oral tissue and its functions in the patient's mouth.

DESCRIPTION OF THE PREFERRED MODALITIES Referring to Figure 1, a perspective view of a preferred support 10 is shown. This support 10 is preferably an integral structure that consists or consists essentially of titanium or titanium alloy. Alternatively, the support 10 may consist of gold, silver, palladium, vanadium, cobalt alloy, stainless steel, and the like.

Any of the titanium or titanium alloy materials used in the implants can be used to make the support 10. Accordingly, by way of illustration and not limitation, one or more of the materials described in the Fstados patents can be used. No. 5,373,621 (titanium / aluminum / vanadium alloy), 5,372,660 (titanium / zirconium alloy), 5,358,529, 5,354,390 (titanium-based alloy containing at least 98% by weight of titanium), 5,334,264 (titanium material) no tronado), 5,326,362 (alloy titanium / aluminum / vanadium alloy), 5,205,921 (titanium coated implant), 5,192,323 (titanium alloy / alumina / vanadium alloy), and the like. The description of each of these US patents is incorporated herein by reference to this specification. In a preferred embodiment, the support 10 is machined with pure titanium which, preferably, is originally in the form of a rod. It is meant that the titanium used meets the standards stated in the Standard of F 67-68 A.S.T.M., "Spec fication for Unalloyed Titanium for Surgí cal Tmplant Applications". In general, it is also preferred that the material used, regardless of whether it is titanium, titanium alloy and / or other material, satisfy the requirements set forth in Normal Analysis F 981-87 A.S.T.M. "Practice for Assessment of Cornibility of Bio Materials (Non-Porous) for Surgical Irnplants". Referring again to Figure 1, it will be seen that the support 10 is constituted by a hollow nucieous 12 extending in the upper part 14 of the support 10 to its lower part (not shown in Figure 1, but see par. lower one 16 in Figure 2). Hollow flute 12 is indicated in Figure 1 by the dotted line 18. Referring again to Figure 1, it will be seen that the support 10 is constituted by a base 20 extending upwards and outwards from its lower part 16 to form an intermediate projection 22. Figure 22 illustrates the preferred structure near the projection 22. It will be seen that, in the preferred embodiment shown, the projection 22 is disposed below the substantially hexagonal portion 24 of the support 1 (1) disposed between the substantially hexagonal portion. 24 and the projection 22 is the annular groove .. Without need to be limited to any particular theory, the Applicant believes that this structure provides a more secure fixation to the devices available to the support 10. Referring again to Figure 1, and in the preferred embodiment shown therein, it is seen that the alternating or substantially hexagonal portion preferably has rounded corners.This is also illustrated in Figure IA, which is a partial top view of the structure of Figure 1. Referring to Figure 1A, it will be seen that the hexagonal portion 24 is constructed of the outer surface containing the alternating linear portions 28 and the arched portions. 30. Without wishing to be bound by any particular theory, it is believed that rounded corners (arcuate portions 30) in this structure are substantially combatible with the patient's mouth. Of this inanera, for example, those rounded corners do not irritate the patient's tongue, while eating, as well as the sharp corners present in the normal hexagonal structures. It is preferred that the length of each linear portion 28 be substantially equal to the length of each of the other linear portions 28. In one embodiment, the substantially hexagonal shape shown in Figure 1 is substantially network-free. It is also preferred that the length of each linear portion 28 is at least about 1.2 times the length of each curved portion 30. In a preferred embodiment, the length of each linear portion 28 is at least approximately 3.0 times the length of each curved portion 30. As will be avoided by those skilled in the art, support 10 may have an exterior shape that does not need to be substantially hexagonal., but can adopt the for of other polygons. In this way, Figure IB represents a substantially curved cross-sectional shape. In this way, Figure 1C represents a substantially octagonal cross-sectional shape. As is apparent to those skilled in the art, any polygonal shape that can be mechanically coupled can be used substantially. Thus, by way of further illustration, substantially triangular forms, substantially pentagonal forms, substantially continuous heptagonal forms, substantially nonagonal forms, and the like may be used. What is required of any such forms, however, is that they engan alternating linear and non-linear sections (the latter being preferably arcuate) and that, preferably, they define a shape that is symmetrical at least along a axis of si etry. Figure 1 is a sectional view of a support 10 of Figure 1. Referring to Figure 2, it will be seen that the base 20 of the support 10 preferably has a width 42 in its lower part-which is substantially less than its width 44 in its upper part. In general, the width 44 is at least approximately 1.1 times the magnitude of the width 42. In a preferred embodiment, the width 44 is 4.7 millimeters and the width 42 is 4.0 millimeters. Referring again to Figure 2, it will be seen that the base 20 has a depth 46 which is preferably about 0.5 to about 7.0 millimeters and, most preferably, about 0.5 to about 1.5 millimeters . In the preferred embodiment illustrated in Figure 2, the depth 46 is 1.0 millirect.

Referring again in Figure 2, it will be seen that, near the base 20, in hollow core 12 is constituted of the stepped perforations 48, 50 and 52. The stepped perforation 52 has a diameter 54 sufficient for a screw to pass through (no. shown) through it. In the preferred embodiment illustrated in Figure 2, the perforated perforation 52 has a diameter 54 of 2.2 millimeters. Referring again to Figure 2, it will be seen that in the substantially hexagonal portion 24 extends in the upper part-14 of the support 10 the annular groove 26. It is preferred that the distance 55 between the upper part 14 and the r- The annular annulus 26 of the support 10 extends at least about 55% of the entire height of the support 10. In a preferred embodiment, the distance 56 is approximately 3.0 millimeters. It is preferred that the annular ridge 26 has a substantially circular shape and, most preferably blernant, that it has a radius of curvature 58 from about 0.1 to about 0.2 millimeters. In a preferred embodiment, the radius of curvature of the slot 26 is approximately 0.1 millimeters. Referring again to FIG. 1, and the preferred embodiment shown therein, the perforation 48 has a diameter 58 of approximately 3.5 millimeters, the perforation 60 has a diameter 62 of approximately 3.0 millimeters, the perforation 64 has a diameter 66 in its At the top point of approximately 3.5 millimeters, the distance 70 between the point 68 and the end of the perforation 60 is 2.0 millimeters, and the distance between the surfaces 68 and the protrusion 22 is 3.0 millimeters. Figure 3 is a top view of the support 10. In the preferred embodiment shown in Figure 10, the distance 74 between the opposing linear surfaces on the outside of the hexagonal sleeve is preferably approximately 3.9 millimeters; and the distance 76 between the opposing arcuate surfaces on the outside of the hexagonal sleeve is approximately 4.1 millimeters. Figure 4 is a bottom view of the support 10. With reference to Figure 4, and in the preferred embodiment shown therein, it will be seen that the perforation preferably has a shape 78 in substantially hexagonal cross section which is adapted to be coupled with the external hexagonal shape of the upper portion of a fixed implant installation (not shown). In the preferred embodiment shown, the distance 80 between the opposite linear walls of said hexagonal shape is preferably 2.7 millimeters. Referring again to Figure 2, it will be seen that the perforation 63 is disposed between the perforation 60 and the perforation 52 and has a continuously decreasing diameter from the perforation 60 to the perforation 62, thus forming a chamfered surface. It is preferred that said chamfered surface forms an obtuse angle (measured with respect to the inner wall 65 of the perforation 60) from about 120 to about 150 degrees. Figure 5 is a perspective view of the carrier 90 which is adapted to be connected to the support 10 and manually deposited in the jaw of a patient. With reference to Figure 5 it will be seen that the carrier 90 is preferably an integral assembly which, preferably, consists essentially of plastic material which preferably is non-toxic and therefore is of "medical quality". Any of the "medical grade" materials known to those skilled in the art may be used, such as, for example, the plastics described in U.S. Patents 5,356,709 (polypropylene copolymer; copolymer of es i re o / i leno / but ileno / est ireno), 5,312,251 (medical grade ceramic material), 5,225,364 (medical grade ceramics), and the like. The description of each of these United States patents is hereby incorporated by reference to this specification. In a preferred embodiment the carrier 90 consists essentially of high density polypropylene that is extruded into the desired shape. Referring again to Figure 5, it will be seen that the carrier 90 is comprised of a fin 92, a handle 94 and a removable cover 96. The flap 92 is constituted by external annular rims 98 which are adapted to fit within and be contiguous with a shipping bottle (not shown in Figure 5). An elastic gasket 99 may be placed between the annular flanges that provide for the easier opening of the carrier 90. The handle 94 is preferably composed of a multitude of vertically extending flanges 100 which facilitate handling of the handle 94; As will be apparent to those skilled in the art, other means may also be used to facilitate hand-held handling (such as, for example, rough surfaces). Within the handle 94 is a compartment 101 on which an accessory part (not shown) can be stored. The removable cover 96 is adapted to pressurize that place into such compartment 101. In one embodiment, the removable cover 96 is color coded to indicate in connection with which part it is to be used. A perforation 102 (shown roughly by dashed line 104) extends from the upper portion 106 of the fin 92 to the lower portion 108 of the fin 92. This portion of the perforation 102 extends through the flap 92 has a substantially hexagonal cross-sectional shape and is thus adapted to be accumulated on and coupled with the substantially hexagonal portion 24 of the support 10. In a preferred embodiment, illustrated in Figure 5, the width 110 of the flap 92 is approximately 9.9 millimeters and the maximum dimension of perforation 102 hexagonally configured as it leaves fin 92 is approximately 4,000 pixels. In the preferred embodiment illustrated in Figure 5, The lower surface 112 of the carrier 90 is preferably a flat surface adapted to engage with the flat surface of the projection 22 (see Figures 1, 2 and 6) so that the carrier 90 is properly aligned with the support 10 when it is connected. rernovibl emente to it. Figure 6 is a sectional view of the carrier 90 connected to the support 10 of which, at the same time, it is connected to the fixed implant installation 114, the support and the implant being disposed within a bottle 116. Referring to Figure 6 , and in the preferred embodiment illustrated therein, it will be seen that the carrier 90 is connected realvibiement to both the cover 96 and the bottle 16 and the support 10, all by a frictional fit. The entire assembly can be arranged in another bottle (not shown). In this embodiment, the depth 120 of the compartment 101 is preferably from about 5 to about 10 millimeters, the distance 121 between the upper lip 122 and the lower surface 124 of the handle 90 is from about 6 to about 1 2 millimeters and the distance 123 from the top- of the reporter 90 to its bottom is approximately 10 to 20 thousand irs.

Referring again to Figure 6, it will be seen that the carrier / holder 10 / flask assembly 16 can be used in connection with a fixed implant installation 114. This assembly is considerably adaptable and can be used substantially with any of the fixed instillations of the implant. implant known to those skilled in the art. In this manner, by way of illustration and not limitation, one or more of the fixed implant facilities described in US Pat. Nos. 5,338,197, 5,061,181, 5,030,095, 4,960,381, 4,932,868, 4,871,313, 4,854,873, 4,854,872, 4,713,004, can be used. 4,468,200, 4,330,891, 4,016,651, 3,672,058, 3,579,831, 2,609,604, 5,376,004, 5,364,268, 5,362,235, 5,302,125, and the like. The description of each of these United States patents is hereby incorporated by reference to this specification. By way of further illustration, and with reference to the Nobelpharrna catalog referred elsewhere in this specification, any of the implant facilities described on page 7 of such a catalog may be used. Referring again to Figure 6, it will be seen that the fixed implant installation 114 is preferably connected to the support 10 by means of a latching screw 130. The retaining ring 130 is shown with details in Fig. 6A "Referring to Fig. 6A, it will be seen that in retainer ring 130 is composed of an internal bore 132 with internal threads 134 adapted to receive and engage with the external threads on a multitude of dental prostheses (not moved). The retaining screw 1.30 is composed of a head portion 131 and a tapered elongated body section 136 that is adapted to fit within the bore 63 (see Figure 2) and engage with the tapered section thereof. The retaining screw * 130 is also composed of external threads which, after they pass through the support 10, can be attached to the internal threads (not shown) in the implant fi xation installation (not shown in Figure 6A). ). The r-holder screw can also be made so that it has a head portion 131 which is tapered from about 2o to 8o and which is received within the support having a reciprocally tapered internal bore. This tapering of both the retaining screw and the perforation of the support provides a better fit and makes it more difficult for the screw to loosen, thus providing a secure fit within the support. Consequently, the tooth attached to the support will be more stable. Figure 6B is an exploded perspective view illustrating that, after the retaining screw 130 is passed through the support 10, it can be screwed into the hole 140 of the implant fixture 114 and screwed in with the threads internal ones located within the optic 14. The preferred embodiment illustrated in Figure 6B, the fixed implant installation 114 is comprised of external threads 142 that can be used to hold the implant assembly with the jaw bone of a patient. Figure 7 is an exploded view showing the support assembly 150 / screw retainer 130 / fixed implant assembly 114, disposed below the socket key 152 with a hexagonal perforation 154. Co or be-a evident for those skilled in the art, the hub wrench 152 can be removably attached to the substantially hexagonal portion 24 of the support 10 and used to insert the assembly 150 into a hole in the patient's jaw. Alternatively, or optionally, depending on the force needed, the carrier 90 may be used for this purpose or, alternatively, to initiate the insertion of the assembly 150 in said hole. In the embodiment illustrated in Figure 7, the fixed implant installation has an external hexagonal shape; and therefore it is adapted to be screwed into the hole in the patient's jaw by a socket wrench with a hexagonal coupling hole. It will be clear, however, that the means for inserting the assembly 150 into the hole of the patient's jaw will vary with the type of use of the implant 114. Thus, for example, when the outer shape of the implant 114 is substantially cylindrical, Any settlement tool (such as a mallet) can be used. These methods are well known to those skilled in the art. Figure 8 is a perspective view of a scissor spherical 160 that can be used in connection with the support . Referring to Figure 8, it will be seen that the catheter 160 sphere is composed of a removable cover 162. Does the scarring sphere function to keep the gingiva apart? another tissue pair-up around the support. The scarring spherule 160 preferably consists substantially of medical grade material such as, for example, medical grade polyethylene. In a preferred embodiment, the scarring sphere 160 consists essentially of high density polyethylene. Referring again to Figure 8, it will be seen that the scarring sphere 160 is comprised of an internal perforation 164 having a hexagonal sub-antral shape and is adapted to fit exactly over the substantially hexagonal portion 24 of the support 10 (see FIG. 9). Referring to Figure 9, and in the preferred embodiment illustrated thereof, it will be seen that the scarring sphere 1650 is preferably constituted by an annular protrusion 166 which is adapted to fit within and removably attached to the annular groove 26. There is in this way a strong fit between the hexagonal portions 77 of coupling and annular coupling portions of the scarring sphere 160 and the support 10. In many cases, the cicatrizing sphere 160 of the support is removed from the support 10 before the time of any dental device. . In some cases, however, it is desired to fix the dental device directly to the scarring sphere 160. In this latter case, it is sometimes desirable to more securely fix the scarring sphere 150 to the support 10. Figure 9 illustrates means for performing with greater security such fixation. Referring to Figure 9A it will be seen that the bolt 170 can be inserted through the catcher sphere 160 into the retainer screw 130 of the support. The polyethylene scarring sphere can also be replaced by a metal-type scarring sphere designed to fit a corresponding denture retainer having a complementary support receiver. The buffering sphere may be adapted to support an individual tooth, or alternatively, several sequencing spherical spheres may be supported together so that an entire bridge unit may be attached thereto. Figure 10 illustrates a denture 180 to which two metal rings 182 and 184 have been curved with rings at 0 186 and 188, at the base side of the denture. Such dentures are well known to those skilled in the art and are illustrated on page 21 of the aforementioned Nobelpharma catalog. In addition, Nobelpharrna also sells an "Overdenture Instrument for Fixation in Sphere" (see page 21 of the catalog) that contains a plastic cap with a rubber ring, 0 replicas of fixation in sphere and separators for fixing on sphere. Referring again to Figure 10, it will be seen that the metal ring / ring assemblies at 0 adjust to friction on the spherical elements 160 to be removably fixed firmly and according to the teeth 180 to the assembly of the teeth. implant. Figure 11 illustrates how the implant assembly 150 can be used in a similar manner with a gold cylinder 190. Such a gold cylinder is well known to those skilled in the art. See, for example, United States patents ,209,659 (gold cylinder 126), 5,108,288 (crown 50 having a member 52 that passes axially through the same and that opens to a polygonal opening at its lower end-), 5,145,371 and the like. The description of each of US patents is hereby incorporated by reference to this specification. It is known that gold cylinders are available for the fabrication of the bar / fastener overdentures, since they are designed to fit precisely over the hexagonal supports and can be incorporated into the bar / fastener structure; see Figure 12 and fastener assembly MX 9706362A Batch: N98JU103 Date: 07/10/1998 Number of pages: 40 Previous document: MX 9706361A mouth of a patient. Referring to Figure 14, it will be seen that the gold arc 210 is composed of an internal hexagonal bore 212 adapted to fit over and engage the hexagonal portion 24 of the bracket 10 (see Figure 15). As will be apparent to those skilled in the art, when the gold arc 210 is placed on the support 10, there are only six positions in which it can be. This configuration provides more precise cen- tral impressions to be made and consequently the teeth can be designed to fit better on the implants. In comparison, the supports according to the prior art, which have cylindrical outer surfaces, have an infinite number of such positions that make precise impressions more difficult to make. This system therefore has several advantages. Since the gold-arc connection 210 / so-called 10 is locked in place by interaction of the hexagonally configured portions, the patient can not cause the tooth fixed to the support 10 to rotate with the application of pressure to the tooth. In the second place, the gold arc 210 can be used as a transfer arc during the pressure turn and, when used in this way, due to the interaction of the hexagonal shapes, it accurately reproduces the position of the support 10 in the work model. Referring again to Figure 14, it is seen that, in the preferred modality used in the mihra, the arc 210 has an upper, substantially rectilinear shape 214 with rounded corners 216. In one embodiment, the upper part of the gold arc 210 has a substantially square shape with more rounded corners. Referring again to Figure 14, it refers to the gold arc 210 containing a multitude of annular grooves 218. The gold arc 210 is also composed of stepped perforations 220 and 222. The gold arc 210 it consists essentially preferably of a palladium alloy such as, for example, the alloy described in U.S. Patent 5,174,954, the entire disclosure of which is hereby incorporated by reference to this specification. Thus, for example, a palladium alloy having from about 50 to about 90% by weight of palladium, from about 0 to about 37% by weight of gold, from about 0 to about 3% can be used. by weight of platinum, from about 0 to 35% by weight of silver, from about 0.5 to about 8% by weight of gallium, from about 0 to about 8% by weight of tin and up to about 0.2% by weight of a material selected from the group consisting of iridium, rowing, ruthenium and mixtures thereof. Referring again to Figure 14, it is preferred that the lower portion 224 of the gold arc 210 is adapted to fit accurately on the projection 22 of the support 10 (see Figure 1). Figure 15 is a sectional view of the gold crown device of Figure 14. Referring to Figure 15 also to Figure 14, it will be seen that the gold arc 210 eeta comprised of a curved neck portion with an area of curvature of approximately 1.5 millimeters. In the preferred embodiment illustrated in Figure 15, it will be seen that the distance 230 is preferably 4.7 millimeters, the distance 232 is preferably 4.2 millimeters, the distance 234 is preferably 5.2 millimeters, the distance 236 is 4.6 millimeters, the distance 236 is 2.7 millimeters, distance 240 is 4.1 millimeters, distance 242 is 3.1 millimeters, distance 244 is 1.5 millimeters, distance 246 is 2.5 millimeters, distance 248 is 2 millimeters , the distance 250 is 1.5 millimeters and the distance is 252 ee of 1.5 millimeters and the distance 254 is 2.8 millimeters. Figure 16 is a top view of the gold arc of Figure 14. Referring to Figure 16, it will be seen that the distance 256 of the opposing flat surfaces 214 is 4.0 thousand irons. Figure 17 is a perspective exploded view illustrating a tooth to which a gold arc 210 has been attached can be attached to the jaw bone of a patient (not shown) by means of the support system of this patient. invention. Referring to Figure 17 and in the embodiment shown, it will be seen that the tooth 270 can be attached to the support 10 by at least two separate means. In the first place, the screw 272 can be inserted into orifice triads 2 and attached to the r-holder screw 130 by engagement with the internal threads 134 (not shown in Figure 17, but see Figure 1). In the second place, the dental cement can be loaded into the gold arch 210 before the moment in which the gold arch 210 is placed on the hexagonal position 24 of the support 10. In this way, in addition to the mechanical union created by screw 232, there is also an adhesive bond. In addition, there is still another union tending to keep the gold arc 210 in position against the support 10 and that is the interaction of their respective hexagonal shapes. The system shown in Figure 17 has the unique advantage that it allows the removal of the tooth 270 from the support 10 even after the cement has hardened. In order to do this, screw 272 can be removed by rotating counterclockwise, and thereafter using a three-pronged arch remover to extract tooth 270 from support 10 by levering between the upper part of the retaining screw 130 against the smaller taper of 270.

A PREFERRED PROCEDURE OF LR INVENTION Figure 18 is a flow diagram of a preferred method of the applicant's invention. In the first step of this procedure, step 300, the support 10 is connected to the fixed implant installation 114. In this step, it is preferred to apply a torque of no more than about 20 Newton / centirnet ro. After that, step 302 of the procedure, a hole is drilled in the bone of the patient's jaw deep enough to receive only the length of the fixed implant installation. In general, this hole is usually from about 8 to about 18,000 meters. After that, in step 304 of the method, the hole drilled in this manner is preferably capped with a cap tool such as, for example, the screw caps illustrated on page 11 of the catalog Nobelph rma. After that, in step 306 of the procedure, the support / fixed implant installation assembly is deposited in the hole by means of a carrier 90. The carrier-90 can also be used to start screwing the assembly into the hole , applying downward pressure while the assembly is rotated. Generally, the carrier 90 will only permit and urge the support / implant assembly a portion of the required distance. The work can be terminated by means of a key-operated hub wrench in step 308 of the procedure. In the next step of this preferred method, the step 310, the scarring sphere 160 is preferably placed on the support 10 (see Figures 9 and 9A). In the preferred embodiment, the cicat pzadora sphere 160 is disposed within the compartment 101 of the carrier-90 before use. After that, in step 312, the teat of the gum on which the hole has been drilled is suture around the scar tissue sphere 160. In the next step of the procedure, step 314, the wound is left to heal-the muscle that is previously the support connect directly or indirectly to a dentadur-a. In general, a healing period of about 3 to about 6 months is desirable. After the desired healing time, no surgical procedure is required, unlike the procedure according to the previous technique (which needed surgery in a second stage to remove the covering screw inserted in the procedure and to fix the support prosthetic). In comparison with the methods according to the prior art, the prosthetic support of the applicant is already fixed. At this stage of the applicant's process, several options are available. In one embodiment, illustrated in step 316 (see also Figure 10), the scarring sphere is fixed directly to a denture to which metal caps with a 0-ring have been cured, in another embodiment, illustrated in FIG. paeo 318, the cicatrising spherical 160 is removed from the support 10. At that stage, several additional options are available. One such option is to fix the gold cylinder 190 on the support 10 (see Figures 11 and 12) in step 320. Once the gold cylinder 190 has been fixed in this way, an overdenture with a fastener can be prepared on bar (see Figure 12) and fix such a denture to the superstructure (see step 322). Alternatively, in step 324, the gold cylinders 190 can be incorporated into the detachable fixed bridge supported with implant and thereafter attached to multiple implants in place in the jaw bone (see Figure 13). Alternatively, on page 326, after the heel pad 160 has been removed, a gold arc 210 can be attached to the tooth (see, e.g., Figure 17 where such a gold arc. is embedded in the tooth). After that, in step 328, such a tooth is fixed to the support 10. The dental support and implant provided by the present invention can be used for patients who have a severe to severe disease that leads to the loss of teeth and Provides more natural and safe teeth that are permanently placed in the mouth. These implants can also be used in case of tooth loss due to accident, deformation, loss or absence of the teeth acquired congenital. The supports and implants described herein can also be adapted for other oral applications such as congenital or accidental bone deformities. It is to be understood that the aforementioned description is illustrative only and that changes can be made in the apparatus, in the ingredients and their proportions, and in the sequence of combinations and steps of the procedures, as well as in other aspects of the invention discussed in the present, without deviating from the scope of the invention as defined in the following claims.
