Abstract

PURPOSE: A method and a material for protecting alveolar ridge are provided to eliminate the wearisome of bone graft operation by retaining the original root form of the alveolar ridge, thus implanting in patient's good time and retains the face appearance good. CONSTITUTION: In order to maintain a configuration of an alveolar bone, a titanium body(TB) which is formed to have a contour similar to a dental root of a natural tooth is inserted into a vacancy which is defined by tooth extraction. The titanium body, divided into at least two segments including an upper titanium segment body mechanically coupled with an implantation post of a lower titanium segment body, can be selectively embedded into the alveolar bone or projected out of a gum. Titanium mesh containing bone graft materials can be filled the vacancy to protect the alveolar ridge so as to remain as a solid fills in alveolar ridge bone.

Description

Prevention method of alveolar protrusion absorption of alveolar bone and its preventive material {THE METHOD AND ITS METERIALS FOR ALVEOLAR RIDGE PROTECTION}

Conventionally, after extraction, alveolar bone is naturally absorbed, and for aesthetic prosthetic restoration, especially in the maxillary anterior part, if the alveolar protrusion is severely absorbed, bone graft is first performed to restore the appearance of the alveolar bone to some extent. Implementing is a way to recover the facial prototype.

As a result, if the contraction phenomenon of the facial part is caused by alveolar bone change after extraction, there are cosmetic problems such as wrinkles in the corners of the mouth. According to the alveolar bone absorption, a change in the shape of the ridge, which is a ridge form of the teeth, comes.

In addition, the absorption of the alveolar bone gives the limitation of the procedure in the production of dentures, especially the maxillary dentures, and in the case of the lower jaw affects the maintenance and stability of the dentures, which is also a very difficult factor. In the conventional method, the bone graft should be performed before the implant, so the cost of the procedure is considerable and the burden on the patient.

In addition, the absorption of alveolar bone impairs the surrounding environment of the alveolar bone tissue to be implanted, thereby limiting the size and width of the implant, thereby limiting the performance of the desired procedure, and the prognosis after the procedure is better than that of the mandible. It is not a reality.

The material used for restoring the absorption of the alveolar bone is commonly called a bone graft material, and various kinds of materials are devised.

Hereinafter will be described the existing bone graft material and its treatment method and problems.

In general, autogenouse bone graft refers to an intraoral or extraoral donor site, which is collected from a tibia, an iliac, and implanted into a desired site.

However, implantation of vital bone marrow and cancellous bone tends to absorb the root of the periphery, and its use is limited due to the lack of autologous bone graft material in the oral cavity.

Next, there are tagraft and xenograft materials, which use a wide range of frozen tagografts but have a limited success rate,

In the case of demineralized or decalcified frozen tarry bone morphogenetic protein (BMP), there is a lack of demonstrable clinical data to convince of use as well as being uneconomical.

Calcium phosphate particles, which are used as synthetic bone graft materials as another bone graft, have two types of chemical structures.

First, as a permanent non-resorbable material, tribasic calcium phosphate (hydroxylapatite, HA: hereinafter called 'HA') is a very small particle, HA-S (up to 15 m in diameter) and spherical particles. It can be divided into HA-500, 1000 (diameter 500-1000 m), etc.

Secondly, it is a resorbable ceramic, beta triclacium phosphate (TCP), a bioresorbable material, small particles (less than 100 m in diameter), and its absorption rate is slow and not absorbed at a constant rate.

Both have no bone inductive capacity, act as extenders for autologous bone grafts, and function as non-irritant fillers.

In addition, aluminum calcium phosphorus pentoxide is a resorbable implant material, which is mixed with the fixative in a very small particle form (less than 70 m in diameter). Absorption phenomenon and tissue growth in the meantime.

On the other hand, the mixture used with these bone graft material is a medical gypsum (plater of paries: calcium sulfate) and as one of the synthetic implant material has good affinity with tissue and absorbency but lacks bone formation ability.

Hydroxylapatite (HA) particles (trade name: orthomatrix HA-500) of high-density deposits and medical gypsum (containing USG Medical Grade Calcium Sulfate Hemihydrate B, 0.85% K₂SO₄), respectively. In the case of 1: 1 mixed mixture (HA / PP), it prevents the root end movement of gingival epithelium and binds the hydroxyluperite particles, facilitating clinical manipulation and filling the site easily. It is a biocompatible and bioresorbable material.

In addition, when alpha-ketoglutarate and malate are used as fixatives for 2 types of organic acids, they have biological resorption and suitability and show histological characteristics on tissue growth between particles as they are absorbed. .

Tagga bones frozen as synthetic bones immediately after extraction by conventional methods

Extraction and seating are performed with bone substitute materials (Brand name: Bioplant HTR, hydroxylapatite, silicate), etc. The extraction and placement are carried out simultaneously. As a result, bone formation is deposited around the HA particles, but after a significant period of time, gradual absorption occurs very slowly. In addition, since frozen bone is made by grinding bones of humans, cows, and sheep, the use of HTR is reduced or restricted due to fears of infections such as mad cow disease and AIDS. The outermost calcium hydroxide (Ca (OH) ₄ : CH in the drawing) reacts with the blood component of the bone marrow to lead to bone formation,

The polyhydroxyethyl methacrylate (PHEMA: polyhydroxyethylmetaacrylate) in the room has the property of X-ray contrast and is absorbed into the living body with the completion of bone formation.

In addition, polymethyl methacrylate (PMMA), which constitutes the lowermost layer, is a biocompatible plastic material that does not break under strong external shocks and is not absorbed after bone formation and remains in bone. Play a role.

However, the strength of the plastic material is not as high as that of the surrounding bone, so if the dental implant is performed in a place where the quality of the bone such as the maxillary posterior part is poor (low density), the surrounding bone having a strong density around the alveolar bone Cannot retain the basic initial fixation and stability of the implant.

Even if the implant is performed after a certain period of time after the HTR implantation, the density of the surrounding bones is still not expected. Therefore, when the dental implant is to be implanted in this area, it is inevitable to select a wider implant size. do.

In general, implants of size 5 to 6 mm in width or more will tend to remove too much surrounding bone, so sufficient bone height and width is possible.

In addition, even if the extraction of the artificial bones and the filling immediately by the method of the artificial bone replacement can prevent alveolar bone absorption, but in the next implant procedure again, the space for the dental implant body in the alveolar bone for implantation For the cumbersome latch drill, which must eventually be partially removed, the reaming operation must be performed.

Eventually, the transplanted bone graft material is effective to prevent alveolar bone ridge absorption temporarily, but it must be removed for dental implants, which is cumbersome and uneconomical for both the operator and the patient.

Non-resorbable bone graft material such as HA in the alveolar bone maintains its shape in the alveolar bone and can be survived for more than 10 years, but there is a permanent change in volume. And the problem caused by the difference in the density of teeth in the area filled with the surrounding bone and the implanted bone graft material remains a research subject.

The purpose of the present invention is to find a method of use and convenience by applying a technical method and an embodiment of a material used in the conventional method for bone graft with the possibility of applying it based on the results of academic research. There is this.

The present invention relates to a method of preventing alveolar protrusion absorption of alveolar bone and a preventive material thereof, and more particularly, to a method of protecting an alveolar protrusion (Ridge), which is a ridge formed by the alveolar bone, and a preventive material thereof.

In the present invention, after the extraction of alveolar bone absorption, immediately take appropriate measures to prevent alveolar bone absorption later, and after extraction, the dental arch form is preserved during prosthetic treatment after a certain period of time. So that you can do aesthetic treatment

In addition, if implantation cannot be performed immediately due to the economic condition of the patient after extraction, the device of the present invention is immediately placed through the extraction and the implantation of alveolar bone, as well as subsequent implantation. Since only the superstructure can be removed, the permanent implant can be directly processed through the socket's interior.

As before, alveolar bone is severely absorbed in the site that is left without any action after extraction.

In the present invention, the cumbersome bone graft procedure can be omitted, thereby increasing the convenience of the aesthetic prosthesis procedure and the dentist's procedure in the dental implant, and also reducing the economic burden of the patient, reducing the alveolar bone absorption phenomenon in advance By minimizing the deformation of the at least it provides a variety of effects, such as preventing the psychological contraction of the operator and patient.

The invention suggests a variety of applications, such as in the form of a toothed form made of pure titanium or titanium alloy. The basic concept of the present invention is to maintain the shape in the alveolar bone forever by using the properties of the physiological biocompatibility, biomechanical and biofunctional bone orientation of the pure titanium of the dental implant with the human body and thus the alveolar bone itself Non-functional embedding titanium temporary implant (non-functional embedding titanium temporary implant or non-functional embedding titanium permanent implant) to maintain the appearance around it to use the property to prevent the absorption of the alveolar protrusion.

The present invention is explained in more detail in conjunction with the accompanying drawings below.

The main idea of the present invention is to protect the alveolar protrusion (ridge) of the alveolar bone by inserting the existing biocompatibility, non-resorbable, and bone-friendly titanium body into the mean size of the tooth type of the tooth immediately through extraction and (渦). will be.

Alveolar bone is characterized by physiological characteristics, and after a certain period of time after loss of natural teeth, the bone is gradually absorbed.Also, ridge absorption of the alveolar bone (physiological absorption of the alveolar bone) and pathological absorption due to periodontitis and alveolar bone due to extraction It is classified into absorption due to aging.

As shown in Figs. 1A, B, and C, the space V in which the root R of the tooth T is removed after extraction of the tooth T from the alveolar bone B and the gum G is blood. This time after coagulation (Blood Clot: BC) is left, the bone formation induces bone formation when time elapses, but when the tooth is lost, the alveolar bone causes bone resorption phenomenon over time, depression (S) ) Is common.

1 D and E show the symptoms caused by periodontitis, and the alveolar bone (B) absorption region (A) around the teeth (T) due to the periodontitis is induced so that the teeth (T) are significantly exposed from the gum (Gum: G) Show status

Due to these physiological and pathological changes, the appearance of the patient after the dropping of natural teeth is accompanied by absorption of the alveolar bone, resulting in shrinkage deformation (RG) of the facial bones and wrinkles around the mouth as shown in FIG. 2. In the figure, UP is the upper lip.

Because of this, even if the prosthesis is performed after the tooth is dropped, the lower alveolar bone continues to decrease, causing the jaw to become smaller (constriction), making it difficult to produce the prosthesis or distorting the form of the dental arch and arch. It makes it more difficult.

As shown in FIG. 3A, in the case of the artificial prosthesis (AT) performed by prosthetic prosthesis (L) of the dropped tooth (ET), the artificial tooth (AT) is formed up to the tooth control line (L). 3B, the appearance is awkward and difficult to reproduce the appearance of the natural teeth, the appearance of the prosthesis can be in the form of a tube made of a tooth-like ceramic, but there is a problem that the appearance aesthetics deteriorate.

In addition, even after prosthetic restoration of partial tooth deprivation after severe alveolar bone absorption, the weakened part of the mucous membrane that is contracted due to deterioration in function or severe partial bias of occlusal force due to partial dentures is caused by pain. Will be

In FIG. 4 showing the mandibular cross section, when the denture flange (F) is installed on the alveolar bone (B) and an artificial tooth (AT) is performed,

It is shown that the tooth adjustment (DC) of the occlusal surface (S) below the denture flange (F) is a ridge shape, which can cause pain. TG is the tongue.

In particular, at least four teeth of the maxillary anterior teeth are extracted, when the absorption of the alveolar bone is severe, as well as the difficulty of prosthetic repair, the implant procedure is also difficult when the absorption is severe and in Figure 5,

It is shown that the height (H) to the upper surface of the lower alveolar neural tube (IC) and the alveolar bone (B) is so small that implantation is virtually impossible.

If the left and right central incisors and lateral incisors of the maxillary anterior teeth fall out, the bones may not be reproduced in the state of severe alveolar bone absorption, even though the bridge work of the maxillary aesthetics can be aesthetically reproduced. Unless special measures have been taken, such as transplantation, all dentists remain in the task of solving aesthetic problems. Figure 6 shows the opening of the jaw (G) of the mandibular alveolar bone (B). By inserting the) back to the gum (G) is shown to suture in the suture (ST).

In FIGS. 8A to 8D, when fracture (F) is caused by external impact or the like on the alveolar bone (B), extraction is performed (FIG. B) and the depth is measured by the gauge G for depth and width measurement. After measuring the insertion of the titanium body (TB) of the present invention has been shown to perform the suture (ST).

When the normal root shape cannot be inserted due to the absorption of the alveolar bone, as shown in FIGS. 9A to E, the tooth T is extracted from the alveolar bone B, and the depth is measured by the gauge G for depth measurement. After forming the cylindrical expansion hole EO by a predetermined length using the latch reamer LR having a diameter of 2-3 mm from the post extraction part (O) and the front end of Fig. 9C, the post P is integrally provided. Titanium body (TB) of the present invention can be inserted into the lower part of the root and extended to perform suture (ST).

Same as the method of FIG. 8, but as shown in FIG. 10, the titan body (TB) is placed through the normal extraction unit (O) together with the dental implant procedure plan to occur at the same time as the alveolar ridge protection, and the titanium body (TB) is inserted. The upper body (TBU) to be separated above and the lower body (TBL) in the form of a support (A) that has already taken the form of a structure for the implant is separated and configured, the upper body (TBU) and the well portion (W) and the bottom embedded in the bottom With a locking taper (LC) that performs mechanical coupling, the lower body (TBL) has an upper post (P) as in the conventional implant system, so that later implant procedures can be configured to allow for later implantation (O). By eliminating the preliminary work such as drilling for cylindrical implant bodies, it eliminates the time and economic burden of both the operator and the patient, and the patient's fear of drilling, and is necessary for various drillings. Reduced equipment costs In addition, as shown in FIG. B, the structure of the upper part of the titanium body (TB) extends to the upper part of the gum so that it can be performed without anesthesia during the second procedure for the implant.

As shown in FIG. 11 at the same time, as shown in FIG. 11, another titanium body (TBL, TBL ') provided with extending the absorbing phenomenon of the alveolar bone B and the cylindrical post P of the root portion, respectively,

Used in combination with the upper titanium body (TBU), it is useful to obtain both ridge protection and dental implants at the same time. In addition, by varying the length and width of the Titanium body (TBL ') to increase the strength of the dental implant to sufficiently withstand the bite force can be implanted differently depending on the state of the lower alveolar bone.

By using titanium powder mixed with the existing bone graft material to form the titanium as a kind of particles (TP) type by using a solid form of the tooth root type with a mixture of the existing bone graft material, Figure 12 and The same Titanium body (TB) can be configured,

In the case of existing bones placed in the food in anticipation of the effect of increasing the strength of the alveolar bone around the socket where the tooth is extracted, the bone growth induction effect is expected due to the non-resorbable, bioconjugated bone-friendly properties. When the titanium particles (TP) are put together, dense bones are formed around the nucleus of the titanium particles (TP), and thus, the effect of improving the bone quality of the corresponding site and the role of increasing the binding force can be expected.

In addition, as shown in Figure 13, it is possible to vary the size of the titanium particles (TP1, TP2, TP3 ..) or to vary the shape of the particles as in TP4.

By using a combination of titanium thread (TT) or Titanium mesh (TM), as shown in Figure 14, along with the existing implant material to enhance the operation and economic benefits of the operator, the future actual implants Even during the procedure, it does not affect the reaming operation and increases the density of the surrounding bones. In the case of Titanium yarn (TT), it is made as a uniform and easy-to-operate thickness, and as shown in FIG. 14, the end of the root is strongly pushed to condense as a dental tool (TO) with the bent tooth (O) or at the same time the bone graft material Together, the results can be obtained as in FIG. 14C.

FIG. 14D shows the insertion procedure into the alveolar bone of the maxilla as a lower density, and also shows that only Titanium yarn (TT) itself is condensed or inserted or mixed with bone graft material. In addition, in the case of Fig. 14E, when the use of the titanium screw for bone bonding during autograft (SB) transplantation is impossible, it is simply fixed by inserting it through an insertion hole interconnected using the titanium screw (TT) and forming a knot. It's a way to do it. SB is a sharply absorbed mandibular alveoli.

FIG. 15 shows the shape of an unfunctional embedding imlant having a mean size of a certain size, which reproduces the external shape of a natural tooth that is immediately inserted after extraction while having a shape most similar to that of a conventional implant under this concept. Titanium body (TB) and its surface is shown to be present in the alveolar bone (B) by performing HA coating or TPS coating (C).

In FIG. 16, a non-functional insertion implant that is removable as a method of adding a convenience to use and adding an easy-to-use and high-precision polishing of the outer surface of the titanium body B to form a polishing surface P for easy removal. removable unfunctional embedding implant: 'RUFEI' in the present invention) can be implemented,

According to the method, the alveolar bone buried type (surbmerge-type) and non-gingival exposure type (non-submerge type) can be divided into.

This type is applied and placed immediately after extraction, and a part of the upper part is detachable so as to provide compatibility (A: abutment) with the conventional dental implant (A: abutment) so that it can also be used as the next dental implant. Irremovable functional embedding implant (IRFEI) that does not remove its lower titanium body (TB)

It is also possible to implement (Figure 18).

In the conventional method, as shown in Fig. 19, when implanting is performed immediately after extraction, the tool is mounted to the internal thread (IT) at the center of the implant body (IB) having a cylindrical round shape and having a thread (OT) on the outside. Insert a hexagon nut (N) for holding

HA coating or TPS coating (C) on the outside, so that the mechanical processing and procedure work during the manufacturing of the implant is very complicated, with the increase of manufacturing cost,

Immediately after extraction of a general patient, implantation is not easy for all dental patients due to the difficulty of the procedure and the prolongation of the procedure.

In the United States, for example, a single implant procedure costs less than $ 2000.00 to about $ 3000.00 (excluding upper prosthetic repairs).

In addition, even if the implant is performed immediately, in the case of the existing implant, since all forms are cylindrical in the form of a cylinder, even if the implant immediately after extraction, drilling for a little reaming work through the extraction and as shown in Figure 20, The additional costs of patients due to the use of the equipment and the complexity of the method of insertion into the alveolar bone are inevitably expensive.

However, in the case of the present invention, immediately after extraction, in the case of normal extraction and in the case of normal extraction, IRFEI or RUFEI is immediately selected and just put in because it is possible to reduce the burden on the dentist and the patient first, and maintain the alveolar bone ridge. The easiest way to do this is to:

In case of implant treatment immediately after extraction, the external shape is similar to the tooth shape of natural tooth, the external surface area is large, and the shape of the implant body is not cylindrical but cylindrical and forms a flat ellipsoid from the center to the outside. Since rotation is certainly prevented, it can be adopted as one of the ideal implants (Fig. 21).

In addition, the part of the upper part removed during the second procedure of the IRFEI, and the part corresponding to the lower part of the remaining part is provided with a sawtooth-shaped protruding pin (F) or an amorphous undercut on the outer surface, thereby providing a mechanical device with the alveolar bone. In addition to the combination can of course increase the maximum outer surface area, of course can be additionally assisted ossification by HA coating (C) or TPS coating.

FIG. 23A provides a Titanium yarn (TT) formed in a thread-like shape of a titanium material having a certain thickness, and the thickness enough to be directly pushed and compressed through the tooth extraction unit (O) as shown in FIG. 23C. It is possible to adjust the density by making it ductile, and partially mixing the mixture.

Therefore, according to this method, due to the sufficient ductility of the Titanium yarn (TT) itself can be a method that can fill every corner of any tooth extraction or (O). As another method, as shown in FIG. 23B, the titanium body (TT) may be wrapped around the implant body (IB) of the implant material and introduced into the extraction chamber.

In addition, as shown in Fig. 24, the external membrane constituting the external shape as the tooth root shape of the tooth is put into a mold for making the root shape by using a titanium mesh woven with a thick titanium yarn (TT) into a mesh shape. When various bone graft materials (BG) are placed in a bag-shaped tooth root shape and placed in the extraction socket, the mesh shape of the bag outer membrane forms a solid body having a constant shape that maintains its appearance forever. Internally, the bone graft material may be put at a certain ratio and configured to allow tissue growth to occur internally.

The main purpose of this form is that it is difficult to manipulate the whole of the disadvantages of HA ceramic particles into a single mass, and because the powder itself is difficult to put in place even if you want to put it in a certain defect part (the existing HA particles have a constant shape. It has the disadvantage of dispersing because it is difficult.) It helps maintain the shape of particles, prevents scattering and maintains the appearance.

When the Titanium net is placed in the ankle and the subsequent treatment for the dental implant, unlike the above IRFEI, the perforation for the new implant must be given strength and thickness that will not interfere with the reaming operation so that it can be drilled. Regardless of the type of implant chosen, it should be possible at the operator's option.

25 illustrates the method of the present invention using particles made from Titanium Plasma Spray (TPS). Titanium is a fine powder (10-20 m in diameter) of titanium particles (TP), which is a biologically compatible mixture (MA) and a tooth-shaped form of a certain solid in advance of various kinds of sizes of the average tooth root It is made more economical and mass production is possible compared to the process of manufacturing the bone graft material by the method of making it through the extraction tooth when necessary, and above all, it is useful for the operator to use.

At this time, the powder-like small powder is a simple permanent non-resorbable ridge prevention material using the properties of biologically compatible materials rather than a derivative of bone growth potential. The concentration can be easily changed to improve the bone quality of the implanted part and increase the bone density.

Existing bone graft materials focus on the role of biocompatibility, non-resorbable or absorbent, bone formation-inducing function and secondary bone enhancer, but in the present invention, because the titanium graft is used in bone graft material, radiological incompatibility Not only does it have permeability, but it is also an opportunity to increase the difference in the density of surrounding bones according to the composition ratio of the particles to an unparalleled level than in the conventional method.

In particular, as shown in FIG. 26, when the bone quality of the maxillary UB is poor (low density), the conventional method selects relatively large implant body (IB) as much as the bone density is low, The length is also longer than necessary to increase the success rate of low bone density,

In the case of using such a titanium particle form, as shown in FIG. 27B, the titanium is drilled a little wider or the same thickness than the implant body (IB) to push the titanium particle (TP) and the mixture (MA) as a tool (TL) such as a condenser. When fully pushed in and finished again with a slightly larger sized tool (TL ') as in FIG. 27C, a conventional conventional implant body (IB) is formed after forming a kind of concreted titanium body (TB). Because the procedure can improve the quality of the surrounding bone tissue, as well as reduce the amount of bone to be removed alveolar bone can be a way to double the effect.

As shown in FIG. 28, the titanium particles (TP) are made of fine spherical powder, and the pure titanium is made into a fine powder in a liquid state at high temperature through a high-pressure spraying device, and then injected into the extraction chamber to prevent alveolar bone absorption. It is a way.

In addition, the particles are fine and various surface treatment (HA coating: C) is possible to promote alveolar bone formation quickly, the bone formation effect is solidified around the nucleus of the titanium particles and does not show absorption phenomenon over a long time. How to use is the same.

In addition, Titanium bodies of IRFEI and RUFEI should meet the following requirements.

First, the structure of the head should be provided with grooves or gripping grooves that can be grooved or gripped at the upper end of the head for ease of handling. When the dental implant is required by the patient's request after satisfying the necessary conditions for a certain period of time, it should be easy to remove. In the case of RUFEI (temporary implant), the upper part should have a round spherical shape to minimize the influence of the occlusal force, and the lowermost part also has a rounded shape to allow the maximum surface area for the surrounding alveolar bone to maximize the distribution of the occlusal force. It must be in the form that it is. In addition, to facilitate removal, the entire surface should be polished with high accuracy and maintained in the alveolar bone for a long time, so that it is not combined with the alveolar bone and only maintains a functional fixed state.

When removing the superstructure of RUFEI or IREFI, which has been placed to maintain the temporary alveolar bone for permanent implant, it is a method of visually identifying the location through the gum of the site. It is advisable to make black plastic material with good biocompatibility so that it can be easily seen and removed after visual inspection during permanent implant procedure. However, due to the complexity of the manufacturing, it may be made of the same titanium material.

The undercarriage of the IRFEI must be shaped for secure engagement with the alveolar bone even when the top is removed, coated with a special TPS or HA to ensure reliable bone fusion, and additionally pinned or shaped with various grooves to provide mechanical interlocking force. Should be given.

Alveolar bone protection method and preventive material of the alveolar bone according to the invention as described above, if you put the RUFEI (removable unfunctional embedding implant) immediately after extraction and prevents the absorption phenomenon of natural alveolar bone following extraction, even after a long time Because it remains in the alveolar bone as a solid, it has the effect of smoothing the prosthetic restoration and improving the aesthetic treatment effect, and can eliminate the hassle of having to perform bone transplantation for the conventional aesthetic prosthetic restoration.

In addition, it is cheaper than any existing alveolar bone restorative materials and procedures, and can be provided to all extraction patients by mass production.

In the case of IRFEI, changing the shape can play the role of a real implant later, reducing the pain of drilling the patient for implant procedures.

Moreover, since it does not permanently change in the alveolar bone and does not change in volume, it is possible to reduce the change in facial appearance without wrinkles in the corners of the mouth, and to maintain a young appearance even with age.

In addition, when manufacturing the dentures of the maxilla, the retention power is improved to improve the chewing function as well as the point of denture pain incidence. Patients who have undergone the procedure have no difficulty in producing dentures, which can increase the chewing ability and reduce the economic burden.

In addition, it is possible to reduce the cause of malocclusion by reducing alveolar bone collapse after tooth extraction, and by performing various bone grafts together, especially when the bone quality of the maxilla is not good, the strength of the alveolar bone As a result of increasing the density, it is possible to improve the environment around the implant. In the case of implantation of existing implants, when the surrounding bone quality is not good, the implant width itself is increased to improve the initial fixation and stability of the basic implant. Compared with a small amount of alveolar bone removal and the selection of a suitable implant size, the stability is easily provided.

Additionally, since the dental implant system is implanted immediately after a loss of teeth or after a certain period of time, the concept of alveolar bone treatment uses bone graft material according to the concept of necessity or need rather than the concept of protection. In this case, the ridge protection that follows after extraction of all patients can be carried out in an indispensable condition.

Due to this, all patients can be improved in advance by the extraction of the prosthesis due to alveolar bone resorption by simply performing with extractions,

The most important thing is that the appearance of alveolar bone resorption and prevention of wrinkles around the mouth as much as the appearance of the appearance no longer shrinks with age.

In addition, if implantation is performed immediately in addition to the extraction procedure, the burden on patients for the drilling of the current cumbersome operator is reduced, and the operator can also complete the procedure in a short time.

In addition, since it approached the root shape of natural teeth by escaping from the existing circular cylinder type, it has the usefulness that the resistance against occlusal force and the force dispersing action are superior to any existing implant system.

In addition, it is true that all patients suffer from significant psychological shock due to the burden of extraction and regret for natural teeth.

By reducing the burden of surgery and the loss of natural teeth, the concept of dental prosthesis can now be approached naturally to all patients in connection with implants, eliminating the psychological impact of extraction.

Indeed, in recent years, a lot of costs must be spent with the implant procedure, but according to the method of the present invention, since the economic burden can be reduced, there are a number of advantages such as to reduce the psychological burden to all patients as much as possible.
