Description

DESCRIPTION

INTERNAL IMPLANT STRUCTURE WITH IMPROVED GROOVE

TECHNICAL FIELD

The invention relates to an internal implant structure with an improved groove for use in dentistry and dental implantology.

STATE OF THE ART

Implants are screws made of titanium that are used to treat missing teeth and are placed inside the jawbone and act as tooth roots. A dental prosthesis is placed on these screws. Implant treatment is a treatment method used especially for tooth deficiencies in the jaws. It acts as a tooth root in people's late or early tooth loss and acts as a physiological organ. The most important advantage of implant treatment is that tooth deficiencies in the jaws can be eliminated without damaging the neighboring teeth. Thus, implant applications in the jaws constitute an important treatment option physiologically, aesthetically, and psychologically.

In the dental implant, which is in the state of the art, the grooves continue in a single row from the tip of the implant to the marginal. In similar applications in this way, long-term problems may be experienced in bone tissue in the marginal region. The groove flow mentioned in some implants continues with finer grooves towards the marginal part of the implant. The marginal region of the implant encounters compact bone during surgical application. This situation may cause a situation that complicates ossification due to the lack of blood supply in the region mentioned during the healing process and the effect of stresses that may occur. Even if a profile is opened to the compact area with a bur (cutting tool) in the implant application, the compact bone is likely to remain under pressure. The stress mentioned is a compression that may be caused in the short term by the pressure created by the implant as well as the chips carried from the lower region during screwing. In the primary, the problem is the risk of bone resorption (melting) due to excessive compression and pressure that may occur in the mentioned region. In addition to these risks, the morphology difference of the grooves in the marginal region also plays an important role in the formation of bone resorption in the stress caused by the chewing loads that come to this region in the long term.

BRIEF DESCRIPTION OF THE INVENTION The present invention relates an internal implant structure with improved groove, developed for eliminating the above-mentioned disadvantages and bringing new advantages to the relevant technical field.

The invention relates to the internal implant structure comprising an improvement in the grooves in the marginal region of the dental implant.

Among the advantages of the internal implant structure with improved groove of the invention, is to reduce stress as the body approaches the compact bone on the surface and transition from the original grooves moving from the implant apex to the implant marginal to the (microporous) microgrooves with channels. In addition, the grooved but microporous surface, which follows the said structure towards the marginal region, prevents bone resorption (melting) by minimizing the stresses in the marginal region that will come into contact with the cortical bone with its conical structure.

DETAILED DESCRIPTION OF THE INVENTION

In this detailed description, preferred alternatives to the internal implant structure with improved groove of the invention are described only for the purpose of a better understanding of the subject matter and without limitation.

The invention relates to an internal implant structure with improved groove, which has a separate channel from the root tip to the neck to ensure continuity.

The invention comprises an internal implant structure with improved groove, which can pass fluidly into the marginal region to ensure continuity and has a separate channel continuing through the center of the grooves in the microporous surface (2) structure. The said flowable structure continues to the upper limit as a fine helical groove with channels (3) and is connected to the inclined marginal edge (1 ) part with a fluent and faint formation.

The angled polish surface region has an inclined marginal edge. There is a platform switch in the inclined marginal edge (1). The inclined marginal edge (1) offers a prosthetic component with a narrower diameter than the neck diameter of the implant through medialization (a method of moving the region from a large area to a narrow area). By removing the implant post joint from the shoulder part of the implant, the fairy implant prevents resorption (melting in the bone) in the bone.

With the inclined marginal edge (1) in the angled polished surface region, treatment is preferred in non-aesthetic regions with high gingival levels and the gingiva has the ability to have a positive relationship with the papillary (keratinized soft tissue between the teeth) in the said region. Thus, cleaning the marginal region is facilitated and accumulation and infection are prevented in regions with high gingiva height. In addition, the angled polished surface region has a positive effect on the success of abutment types such as ball attachment (knob snap abutment), and locator (cylindrical snap abutment), especially used in hybrid prostheses, and also supports the prosthesis-gingiva relationship positively in screw abutments. Another feature of the inclined marginal edge (1) is that it comprises an octagonal structure. Thus, the fixed-diameter octagon constitutes an important alternative to similar structures. With the said octagon structure, the force is spread over a wider area, especially in the molar tooth region. In addition, when viewed as a cross-section, the abutment connection of the octagon is conically designed and planned in an angular form that will create serious resistance to high forces, especially in hybrid prostheses and molars. It comprises an inclined marginal edge (1) that allows the octagon structure and force to spread evenly in each region of the implant and crown.

The microporous surface (2) in the marginal region is compatible with both bone and soft tissue. The microporous surface (2) is around 0.5 RA and presents a risk of reduced periimplantitis (an infection around the implant that occurs due to surgery, prosthesis construction, or due to the tissues around the implant and causes bone loss in the surrounding tissues). It also provides excellent bone soft tissue relationships. It improves the load distribution due to its micro-particle structure. The microporous surface (2) is one of the important factors that balance the load on the compact bone and prevent bone resorption (melting). The microporous surface (2) area in the marginal region with a width of about 1 -1 .5 mm is inclined inward at 5 degrees due to the beginning of the conical connection and prevents the marginal region from creating stress in the cortical bone. It comprises a microporous surface (2) that does not cause excessive stress on the compact bone and thus minimizes the risk of bone resorption (melting).

The fine helical grooves with channels (3), which are close to the marginal region, have a fine structure and minimize the stress on the bone since they are in the form of an extension of the microparticles. The said fine helical grooves with channels (3) do not cause stress on the bone, due to their structure, it settles into the bone without excessive stress and plays a role in the increase of primary stability. It is designed in a structure that will not cause stress in the marginal region where the bone approaches the cortical more and more. The energy exchange it makes with the bone is mutually equal. It has a design that settles into the bone without pressure. The aforementioned design promotes bone formation in the marginal region without stress. This plays an important role in terms of good osseointegration (direct structural and functional connection between living bone tissue and the implant surface under loading) and the subsequent balancing of marginal forces. The said fine helical grooves with channels (3) have an ideal design that can adapt to compact bone. The fine helical grooves with channels (3) formed by a channel passing through the middle of the grooves after the grooves without steps and channels (normal grooves) (4) coming from under the body ensure that the bone chips are transported to the marginal region in a balanced way, on the one hand, and on the other hand, they turn the stress that can be created by the minimally expanded body into an excellent stabilization (gaining quality that will not change or deteriorate). Thanks to the fine helical grooves with channels (3), the minimal expansion in the marginal region of the bone provides excellent primary stability, while the occlusal (on the chewing surface) pressure to the marginal region is best balanced. The Fine helical grooves with channels (3) act as a kind of roof in the bone, play a positive role in transferring stress and supporting osseointegration (the direct structural and functional connection between live bone tissue and the implant surface under loading) and create a balance of force. The fine helical grooves with channels (3) ensure a balanced distribution of forces over the entire implant surface. Thus, it both supports implant stability and osseointegration and prevents the implant marginal (both the implant material and the bone tissue around the implant neck) from being exposed to excessive pressure. The grooves without steps and channels (normal grooves) (4) moving towards the marginal region have an ideal design that can adapt to the spongiosis bone. The grooves without steps and channels (normal grooves) (4) allow bone chips from the vertical section under the body to be transported to the marginal region on the one hand, while on the other hand, they play a role in converting the stress that can be created by the minimally expanded body into a perfect stabilization. While the minimal expansion in the marginal region of the body provides excellent primary stability, the structure of the invention, which is found with delicate grooves in the marginal region following the normal grooves (4), best compensates for the pressure from the occlusal. It comprises normal self-slotting grooves (4) in the implant body (5), which provide increased area and primary (initial) stability in osseointegration. It acts as a kind of roof in the bone and plays a positive role in the transition of square normal grooves (4) to fine helical grooves with channels (3) in terms of transferring stress and supporting osseointegration. It provides a smooth transition and creates a balance of force. It ensures a balanced distribution and transition of forces to the entire implant surface. Thus, it both supports implant stability and osseointegration and prevents the implant body from being exposed to excessive pressure.

Normal self-tapping grooves (4) in the implant body (5) provide more surfaces and better primary (initial) stability. In addition to being active, these normal grooves (4), which provide an excellent relationship with the spongious bone, do not cause pressure or heat in the bone during insertion thanks to their entry forms, and they create optimum (best, most suitable) adhesion after insertion. These normal grooves (4) constitute an important primary (initial) stability and osseointegration area within the body as a whole. The normal grooves (4) in the marginal region provide surface width on the one hand and are excellent retainers during the first application on the other hand. Thanks to the aforementioned retention of the normal grooves (4), it becomes easier to apply the implant to the cavity (the space opened by burs into the bone to apply the implant), and even with a very short turn, the normal grooves (4) catch the bone and self-screw. After that, they help and support primary (initial) stability. First of all, the implant body (5) offers a wide and narrowing root structure in the marginal region suitable for jawbone anatomy in humans with a conical root-type design.

The vertical sections (6), which come in the form of an inclined helix from the root tip, end faintly in the channels starting from the middle region of the normal grooves (4), which move upward from the implant body and become more prominent. Thus, while maintaining the integrity of the body, the chips carried by the vertical section (6) are transmitted homogeneously into the grooves. This movement is a precursor to the hydrophilic feature of the implant, which on the one hand ensures rapid contact of the surface with the blood and creates osteoblastic (blood cell that forms the primary bone tissue, synthesizes the organic substance of the bone matrix "glycosaminoglycans and collagen type I") activity, while on the other hand supports its primary stabilization and helps the self-tapping implant body to settle comfortably in the bone. Thanks to the first retention (adhesion), it comprises normal grooves (4) that facilitate the application of the implant to the cavity and enable the implant to selftapping (screwing) by capturing the bone. Vertical sections (6) support the rotation of the body thanks to their morphology during application and collect bone chips with minimal friction during this rotation and transmit them to the marginal region along the body.

The strut grooves at the implant root tip (implant apex) (7) allow the implant to easily capture the bone with its balanced sharpness and deep structure. The mentioned structure decreases in depth and progresses horizontally to the marginal region. The mentioned form both maintains the resistance of the body and creates resistance to the reverse forces that the body may be exposed to after osseointegration. In this way, the implant is easily attached to the bone and then screwed by self-tapping with simple screwing pressure.

The implant base (8) is the morphological structure at the root tip. It provides easy application without damaging the jaw bones and anatomical formations and ensures that the application is safe and stable, especially in sinus lift operations, with its conical, straightending structure at the root tip. The implant root tip (7) is designed to be partially sharp so that the grooves can catch the bone well at the first stroke. However, on the contrary, the implant base (8) is terminated extremely flat and soft. This termination does not perforate the anatomical formations protected by compact bone in any way. When desired, it can expand the sinus base without perforating and does not damage the anatomical structure. It provides a safe application in regions close to anatomical formations.
