Description

MONOBLOCK IMPLANT THAT CAN BE BENT, ANGLED AND SCREWED Technical Area

This invention is related to the monoblock tooth implant, which can be bent and screwed, and its feature is characterized by the use of screws instead of cement to secure the crown to the abutment part. Prior Art

A Dental implant is a biomaterial that mimics the root of the tooth and combines with the abutment part and crown to replace the missing tooth or teeth. Implants provide much better chewing and speaking functions than traditional forms of bridge and prosthetic treatment. Currently, it is the most commonly used method of dental treatment and aesthetics. Implants are roots whose screws are of a certain thickness and width. Thus, the thickness of the jawbone should be sufficient in the area where the implant will be applied, and its height and width should also be suitable for the implant. The quality the existing bone also affects the success of implant treatment. In addition, it is one of the necessary conditions for the gingiva to be completely healthy before the implants are inserted and during which the implant remains in the mouth.

Implants are a method that can achieve very successful results for both the patient and the doctor, used for many years with an accurate diagnosis with an adequate level of knowledge and experience of the doctor.

Implants can be defined as an artificial tooth root that is placed in the jawbone and produced from appropriate materials to restore the functional tasks and aesthetic posture of lost, broken or missing teeth. There are many types of dental Implants. But the most commonly used type of implant today is implants that are 'screw' shaped. The types of dental implants are determined by the area in which they are placed and the supporting tissues.

Accordingly, the types of implants are: Endosteal (intra-bone) implants

Intramucosal inserts

Endodontic stabilizers

Transosseous (transmandibular) implants

Subperiosteal implants. Endosteal (intra-bone) implants: They are the most commonly used type of implants. Screwshaped ones are used more often. Other varieties are cylinder or knife-shaped. Each implant holds one or more prosthetic teeth. It can also be applied to patients with bridges or removable dentures.

In the two-part implant system, an incision is opened in the patient's mouth to make the infrastructure of the implant, then implantation is performed and sutures are performed to make the superstructure. Then the osseo-integration of the implant into the bone is waited. After the fusion occurs, the superstructure is made and the tooth-like structure called the crown is passed. During bone implant fusion, the patient remains toothless. After the operation by removing the Flap, the seam is removed and healing is waited. The flap is removed again to place the abutment after healing. This presents a troubled long recovery problem for the patient. In two-part implants, it is a disadvantage that the patient remains toothless for a long time. With periimplantitis disease, which can occur due to micro-leaks that may occur in implants consisting of two parts, there may be loss of gums, jawbones and other teeth. In traditional surgery, much more complex surgical procedures are required. These procedures take a period of 3-6 months and are spread over 2 or 3 sessions. The patient remains toothless in this process. For different application techniques in two-piece implants; it is a disadvantage for the doctor that abutments which are produced in different models, different angles, different gum heights and different diameters create too many options and the doctors are unable to create a suitable superstructure restoration for each case. Although there are many types of abutment parts, it is not possible to produce implants at all angles. This condition may cause the physician to be unable to create the structure he wants.

In order to solve the problems caused by two-part implants, one-part (monoblock) implants have been manufactured.

Compared to traditional implants, the monoblock implants eliminate the need for cap screws, healing abutments, subsequent separate implant inserts, or separate implant abutments. The advantage of one-piece implants is that they eliminate long surgical operations. However, poor angulation during implant placement has negative consequences for the patient. Bad angulation causes the chewing forces to not be evenly distributed and the jawbone to be damaged and implant loss due to poor mechanical loading.The invention with the publication number TW201515640 and the Bionica brand Conefit Slim product have the disadvantages of the mentioned monoblock implants.

Because abutments from different angles are needed for equal distribution of chewing forces and placement of the implant at the right angles, monoblock bent implants have been developed. Monoblock Flexable implants allow angulation to be performed more accurately for equal distribution of chewing forces.

The application of a bent monoblock occurs as follows: the location of the operation in the patient's mouth is determined. The appropriate implant is determined by taking into account the structure of the jaw and the thickness of the gums. After that, the implant is placed directly on the flap without an incision operation. It is then checked whether the implant is located at the correct angle. If there are angular problems, bending is performed using the apparatus suitable for prior art. Then the crown is fixed to the abutment part with the help of cement and the process is completed. But there may be some problems here. The main problem is that the bent implant has now lost its basic dimensions. The implant is bent in a relatively narrow section between the screwing part entering the jawbone and the abutment part and surrounded by the gingiva This bending process can create pressure on the gum at a certain point. Bonding the crown to the abutment part, which is the preferred application in the prior art, increases the risk of peri-implantitis when combined with the possibility of this pressure. At the point where there is pressure on the gum, infection may occur due to contact of the face with the gum over time. The invention with the publication number IN2678MU2013 and the product called the speedy implant system of the bionica brand includes the disadvantages described above as the monoblock implant mentioned.

In the prior art, an implant is needed that can be bent in one piece and eliminate the risk of peri-implantitis. Purpose Of Invention

An object of the present invention is to obtain a dental implant which is a monoblock, which is below the abutment part and can be bent from the place whose diameter is smaller than the other parts, which is used instead of the tooth in case of total tooth deficiency and aims to replace the adhesive that fixes the crown called cement on the abutment part.

Another aim of the invention is to eliminate the peri-implantitis disease caused by the adhesive called cement coming into contact with the gums as a result of bending, with the screwing system it develops.

Another goal of the invention is to obtain a monoblock implant that can be compatible with the jawbone. Another aim of the invention is that when the appropriate angular placement of the crown is desired, obtaining an implant that can be bent to bring the crown to this angular position.

Another purpose of the invention is to obtain a monoblock implant in which the crown is fixed by screwing into the abutment, which can be bent if necessary.

Another purpose of the invention is to obtain an implant where the bending apparatus has channels and slots to prevent the deformation of the screwing cavity on the abutment during bending. Another purpose of the invention is to obtain a bendable, monoblock implant in which the Crown can be screwed into the abutment and removed with the help of screws, eliminating the need to replace the abutment in case of tooth breakage.

Detailed Description Of The Invention

Here," osseointegration " is used in the sense of integration of bone and implant after implantation.

Here, the term” periimplantitis " has been used in the sense of inflammation arising out of surgery around the implant, and especially caused by the cement, which is used to fix the prosthesis during the construction of the prosthesis, or emerging in the tissues around the implant, which leads to bone loss in the surrounding tissues.

Here," angulation " was used in the sense of adjusting the implant placed in the jawbone to the correct angle.

Here," monoblock " was used to mean that the part of the implant that screws into the bone, the bent part, and the abutment part coexist in a single part.

Here, "cement" is used in the sense of a chemical that has a bonding property to secure the crown(3) to the abutment section. Here, "flap removal" was used in the sense of cutting the gum and revealing bone tissue.

Here," support tissue" is used in the sense of bone that allows the implant to be fixed from the screw.

Here" abutment " is an artificial tooth cut form that allows the crown(3) to the placed on the implants. After the healing period after the Implant is made, the abutments are placed on the implant and the teeth are produced with the measurements taken from it. This invention is a monoblock dental implant that can be bent and screwed, which replaces the tooth in total tooth deficiency. A dental implant is used in different types and structures when there is a lack of teeth. This invention was developed to eliminate the disadvantages in the known state of the technique mentioned above. In implants that can bend a monoblock, bending is performed from the place, which is small in diameter, under the abutment section to hold the part called the abutment section at the correct angle. After bending, the screw system is developed to screw the crown, pre -prepared according to the prior art, into the screw slot located in the abutment section.

The invention includes the implant (1); the jaw screwing part (7) that ensures the fixation of the implant (1) to the jaw, the bending place (6) located in a relatively thin structure and at the height of the gingiva from the part where the said jaw screwing part (7) is limited to the gingiva, the crown (3) placed above the bending place (6), the abutment (5) where the said crown (3) is placed, the crown support (5.3) that allows the crown (3) to be restricted to the gingiva, the abutment support (5.7) on which the crown support is placed, the crown placement surface (5.2) that prevents the crown (3) from rotating and enables the crown (3) to be placed on the abutment (5), abutment surface pit(?) provided that there is at least one above the said crown seating surface, the crown screw (2), which is used to fix the crown (3) to the abutment (5), which fits on the crown placement surface (5.2) of the crown (3), the abutment screw slot (5.1) of the said crown screw (2) and the crown (3) that gives the tooth appearance the crown abutment space (3.1), which allows it to be placed on the abutment (5), the crown screwing slot (3.2), through which the crown screw (2) passes, which places the crown (3) on the crown placement surface (5.2) and fixes the crown (3), which is seated on the abutment (5), with the help of the crown screw (2), and the crown screw support (3.3) and the crown screw head (2.1), which apply opposite force to each other, which ensures that the crown (3) holds the abutment (5) stably, the crown screw head (2.1) that ensures the crown (3) to be fixed to the abutment (5) It comprises the crown screwing section (2.2) which provides reverse force and is located on the crown screw (2).

After the crown(3) is fixed to the abutment(5) section with the help of the crown screw(2), the crown fill(4) or the Crown screw head(2.1) is used to fill the gap remaining in the Crown screw slot(3.2). The invention can be produced in different sizes according to different support tissues. Without lifting the flap, the jaw screwing part of the implant(1) is fixed to the bone(7) with the help of instruments in the prior art. After the jaw screw part(7) is fixed to the bone, the bending process is performed from the bent place(1) of the implant(6) with the help of the adapter(8) to keep the abutment part (5) at the correct angle. After bending to the appropriate angle, the crown(3) is fixed to the abutment (5) section with the developed screwing system. After securing the crown from the crown screw slot(3.2) on the crown(3) to the abutment(5), the Crown(3) is closed with the crown fill(4) to close the Crown screw slot(3.2) opening on the crown(3). The adapter(8) intertwines the adapter protrusion(8.3) in the adapter abutment cavity(8.1) and the abutment surface pit(5.5) to prevent the adapter(8) from rotating to bring the abutment(5) to the correct angle.

The abutment adapter support (5.6) enables the crown screw (2) to grasp the abutment (5) and reduces the problem of not grasping and the pressure on the gingiva that may occur during the rotation process. The adapter(8) has an additional advantage of applying pressure by placing on the abutment adapter support (5.6) located on the crown support during bending. The crown support section is filled to exclude the screw gap, and the pressure applied here during bending eliminates the need for additional pressure on the crown screw slot(3.2). In this way, both the desired bending has been realized and the size of the crown screw slot(3.2) is preserved.

Application Of The Invention

Sometimes the appropriate amount of bone may not be present in the area where the Implant will be applied, for various reasons. In this case, after the evaluation by the maxillofacial surgeon, the bone volume is increased to the desired dimensions by performing bone formation operations with known procedures in the prior art to the relevant area. In cases where linear operation on the jawbone is not possible, the implant(1) is angled to the jawbone. In this case, the linear implant(1) placed at an angle is no longer at the correct angle in the abutment(5) section. The angular placement of the abutment(5) section is brought to the appropriate angle with the help of a smooth linear adapter(8), and the crown(3) is screwed to the abutment (5). In this way, the dental implant(1) is completed without having to wait months for bone healing.

The exemplified stages of this implementation are as follows:

A monoblock implant(1) is selected according to the area where the Implant will be applied, With an apparatus suitable to the prior art, it is placed on the jawbone at approximately the appropriate angle,

(1) the bone-screwing section of the implant positioned in an Ideal location is fully built into the jawbone, the bending site is built up from the jawbone by the thickness of the gum, and the abutment(5) is located to begin at the upper limit of the said bending place,

The angular placement of the(1) abutment(5) section of the said positioned implant is inspected,

If there is an angular difference, the abutment (5) section is bent as much as the amount needed from the implant's(1) bending place with the help of the appropriate bending apparatus, The pits(5.5, 5.6) on the abutment surface and on the abutment adapter support(5.6) are compatible with the built-in protrusions in the abutment(5) slot of the adapter. The mentioned abutment surface pit(5.5) and abutment adapter support(5.6) correspond exactly to each other when the adapter(8) is placed on the abutment(5).

In order for the said bending to occur, the adapter(8) that will allow the bending to the abutment(5) section is attached as described above, and the force is applied to the force arm, and the abutment(5) is brought to the desired angle,

After the implant is brought into the appropriate angular shape, the crown (3) is placed in a way that the crown abutment space (3.1) covers the abutment (5) part,

During the mentioned placement, the crown screw slot(3.2) is placed to correspond to the crown screw section(2.2) on the abutment (5),

After placing the crown(3) suitably with the abutment(5), it is fixed with the crown screw(2), After fixing the crown screw(2), The crown screw(2) provided a stable grip by compressing the crown resting place(5.3) and the abutment wall (5.4),

After the mentioned screw, the crown screw slot(3.2) is closed with crown fill (4), providing a natural tooth appearance. One of the alternative filling methods known in the technique can also be applied here. As an example, crown screw head (2.1) can also be applied in the same color as crown(3).

The invention provides a more robust grip thanks to the screw system developed against the possible crown(3) protrusions.

In case of possible crown(3) losses, the crown screw(2) is opened and the new crown(3) is installed in its place.

The invention also suggests a method for applying a dental implant(1). Accordingly:

- Selection of a monoblock implant(1) suitable for the area where the Implant will be applied,

- Placement of the selected monoblock implant (1) at approximately the appropriate angle to the jawbone with the appropriate apparatus,
