Abstract

The invention related to medicine, in particular to surgical and orthopaedic stomatology and can be used for fixing dental prostheses. The aim of said invention is to simplify the insertion of an extraosseous part into an implant, increase an initial force for fixing said implant to an osseous tissue, reduce a treatment period, simplify the implant introduction and to form an optimal marginal gingiva. The inventive stomatological implant consists of an extraosseous part provided with a screw and an intraosseous part consisting of a gingival border and a threaded apical part. The novelty of said implant lies in that it comprises a head thereof which is provided with an internal thread and internal hexahedron for introducing said head into the implant, the use of the thread whose pitch ranges from 0.7 to 2.0 mm and the profile height thereof on the apical part is equal to 0.3-1.2 mm and the walls of a mounting bore inside the implant are provided with slots for introducing the implant into the osseous tissue.

Description

Dental Implant

The invention is subject to medical and medical equipment and is intended for use in medical and non-medical devices. It may be used This invention is for implants intended for implantation in a large tissue, especially for dental implants for implantation of dental prostheses.

BACKGROUND OF THE INVENTION (LEVEL OF TECHNOLOGY)

Β The current time in the serial production and the clinical use is dominated by screw (threaded) imports, usually produced by the United States or the United States. Such implant systems can be widespread for two-stage implantation or not widespread for single-stage implantation. For connection of internal and external parts of the loose implant, use the threaded connection and the nozzles carried out in the form of heat. Many of the many implant systems also have interconnecting elements (implant plug and gum connector) that are connected to the implant and are connected to the implant. These elements are inserted into the implant when using a six-digit return.

After the waiting period (usually 3-6 months), the first step is to enter the head of the implant, to remove tears and to fix the prosthesis. Implant heads (abutments, external parts) usually have an internal thread for dental implants and are implanted in special cases. 2 After the implantation of the prosthesis, the implant and, surrounding it, the large fabric begin to maximize the activity of physical loads.

In addition, the introduction of the head of the implant into the implant requires a special tool. The head of the implant has its own external part and is tied to the internal part of the instrument and is threaded. When changing the size of the head of the implant, it is necessary to change the size of the instrument of introduction, which complicates the system (set) of implants. The separation of the instrument and the head, after its introduction into the implant, requires the use of a wrench and a repair wrench, which significantly complicates the treatment and the treatment.

The installed thread options are a preferred embodiment of the invention.

SUMMARY OF THE INVENTION Explains Fig. 1,2,3,4,5,6,7. The implant is made up of internal 1 and external 2 parts. FIG. 1 The intrinsic part is made up of the last 3 and the first 4 parts. The wide part is made in the form of a self-cutting screw with a thread pitch of 8 from 0.7 to 2.0 mm., With a height of 0.3-1.2 mm. Height of threaded thread may vary due to changes in the threaded thread and threaded end. An emergency (internal) part of the implant may be completed by a special or special offer, and may be either a traditional or traditional or improper one. An unscheduled height of 5 may be performed with an inconsistent user profile, a truncated user interface, and, at the same time, overloading at the top and bottom, or not. An implant may have an incomplete thread profile and a private involvement at the end of the living area. Completion of the final part 6 completed, may be performed flat, may have a failure, antifungs (discarded). The unfortunate part may be performed by a cynical or cylindrical form. Part 4 Pρisheechnaya οbychnο κοnichesκοy φορmy with mnοgοzaχοdnοy ρezbοy imeeτ sκοshenny ποyasοκ vτοροy ποyasοκ 7 and 8 (sheyκu, tseρvzhalnuyu Part) or κοnichesκy tsilindρichesκy, κοτορy mοzheτ byτ οτποliροvan or οbρabοτan πesκοsτρuynym meτοdοm. As a result, it may be used or processed in a manner that is easier to use for a smaller part or a half of its own. 7 The mowed area 7 has a usual loss of slope from 5 to 85 °; (it may have a value of minimally close κ 0 to maximally close κ

90). As a result, it may be used or processed using a sandblasting method. As a result, you may be able to cut or process the appliance at a lower level for a larger part or half of it. The angle of the oblique and the method of processing will allow you to lower the depth of loading the implant in a way that helps to minimize the risk of physical inactivity.

The implant has an offensive FIG. 5 answer-final

(nozzle cone) 9 or cylindrical. At the stade of an emergency (cone) 9, there were a wide range of 10; The number of slots can be from 1 to 12. The combination of slots can produce multiple units (Fig. 6,7) (switch, square, hex, etc.). As a rule, at the nursing plots, below the outer shell there are four slots made, which are equally remote from the patient. Slots can serve as a means of introducing an implant into a wide fabric, as well as connections with implant heads having corresponding slots or hex.

There may be two slots located on the other hand of the friend, for the introduction of a flat slotted return.

The implant may have four slots for convenient and easy access, and for the introduction of a simple and flat spline

(tools).

As a performance variant, the implant can have access to an open guard, lower than the external open-end slots of the regular 8 forms, in order to do so in the section of the figure (square, square, and other plurals).

The implant may be performed with a nozzle, on the other hand there is a threaded connection for connecting with the external part. J of introduction to the random fabric below the landing case may have a six-sided (six-sided channel) disconnected, it is unloaded

(outside).

The non-standard part 2 (Fig. 2) consists of the following elements: a shortened truncated body with a fringe 15, a sixteenth, a 11th part, and a 11th part.

The non-standard part can be performed with an internal hex over the thread, and with this size the hex is larger than the diameter of the thread. The length of the gingival cone can vary from 0.5 mm to 5 mm, due to the change in the size of the body of the cone, so that you can choose the head of the implant depending on the thickness of the gum. 9 J Fill-ups use a turn-off screw with an internal hex, the sizes are just the same as those of the internal hex-points.

The optional part may be fitted with a detachable screw. Implant and external parts are made from titanium alloys brands 1-0, ΒΤ1-00, ΒΤ6, ΟΟΟΟΤ 19807, and also ΟгаΟеΙ- ΟгаΜν

-Α8ΤΜ Ρ67-89 and ΙδΟ 5831 P. The implant can be turned on and can be processed or otherwise processed by the implant

The implant is also performed in the form of a single-stage oppression.

ΦigZ. With this implant, it is integrated from the internal 1 part, which is integrated with the external 2 part (connected inseparable connection). The real part is made up of the last 3 and the worst 4 parts. The complete part is made in the form of a self-tapping screw (screw) with a thread pitch from 0.7 to 2.0 mm., With a height of 0.3-1.2 mm. The high quality of the thread can vary due to the low cost of the thread and the thread end. An unscheduled height of 5 may be performed with an inconsistent user profile, a truncated user interface, and, at first, with overloading on top and in the base or with power supply. The end of the final part of 6 was completed in Shushy; it may be completed, with impairment, there is a failure on the part, antiparticles. The unfortunate part may be performed by a secondary cylinder cylinder. Inventory part 4, usually in physical form, may have an attempt in part 8 (neck, main part).

The non-conventional part usually has a gingival part 19 (swollen or cynical) with a loss of 14, a cylindrical part 15, a brown 10 seat shell, with internal threaded 17 along with integral axle and hex 18. The length of the gingival part is 0.5 to 6 mm, which means that it requires little wear.

The non-standard part (implant head) can be enlarged slightly above the gingival cone, with the screw being rotated, which means that the distance is independent of the other.

The introduction of the implant into the external container of the extraordinary part of the common or ordinary groove 20 on the livelihood; There may be an external hexagon in the base of the body, and also in the case of the body.

The implant and external parts are manufactured on universal technical experience, as well as on CNC machining centers from titanium alloys Mark-0, ΒΤ1-00, ΒΤ6ΒΤΙπππππππππ

-Α8ΤΜ G67-89 and 180 5831 P. The intact version of the implant can be changed by sanding or by using a method (modification) of processing or processing.

The method of implantation using the implant and head.

When introducing an internal implantation in the toothless part of the alveoli, the formation of the bed of the implant implants is amelioration - or miscarriage is impaired. First, the gum is punctured by the use of flour or phrases, then the gum is punctured, and it is necessary to start with a smaller length of hair. 11 Equal to the diameter of the housing, creates a cylindrical hole to a depth equal to the length of the implant. Then, a final phrases, having a smaller diameter of the implant by the size of the threaded port, produces a hole to a depth equal to the length of the implant. The implant is introduced into the foreign fabric, cutting the return screw with the rotation of the implant, due to and due to the insertion of the external part of the instrument and the shredder

(in the other case, the shortcut to the body), you will get the finished compression in the short-lived container.

The method of using the head of the implant.

After the traditional method, the head of the factory is produced during the period of the pediatric stage i.e. After installing gum tissue and healing the mucous membranes. However, when administering the installation of gum surgery, in most cases, it is not obligatory and only prolongs the treatment. With earlier loadings, there is generally no difference between a single-stage and a two-stage methodical method. Therefore, the use of the Imperial implantation with the end of the gingival part will result in the treatment of the patient being damaged. After a slight failure, it was created in the gum with a six-sided return; The primary gingival part of the head of the implant facilitates rapid adherence and formation of optimal contact with soft tissues. Existence below the threaded channel of the head of the internal hexagon of the same size as the hex with the plug 12 implants will help to eliminate the installation procedure (introduction) of the head and reduce the number of instruments in the implant kit.

For the operation of the drive, the drive screw is used with an internal hexagon;

The methodology of the introduction of the one-stage imgshashapiya (chirurgical stage).

Since both the implant implant is in possession of an access to a good first-aid implantation, the implantation of an external implantation is free of charge.

(Takes advantage of a two-stage or two-stage implant construction with a head).

Immediate or local anesthesia, without the incision and flaking of the mucous-obstructive gland, results in an obstructive gum injury.
