The invention relates to a dental implant useful in dentistry.
We know a dental implant / 1 / with a construction closest to the one offered, which is a combination between subperiosteal and intraosseous parts. The subperiosteal part is a saddle-shaped frame with two end arches and an intermediate arch, in the upper part of which is the neck and head of the implant. To the two end arches below there are protrusions, which represent the intraosseous part of the body, so that their level is lower than the level of the arches of the frame of the saddle and the head of the implant connect to this part. The intraocular part is a flat element located along the longitudinal axis of symmetry of the implant, directed in the lower part and with shaped holes in it, and its size in depth is smaller than that of the saddle frame.
Disadvantages of a known dental implant are that we can use it in private cases only when there is enough bone to place its intraosseous part. For these cases we use „combi implants“/ Heinrich / with light upper limiter: It is applicable in the area of the 6 teeth, where in severely atrophied alveolar bone - and these are common clinical cases - the maxillary sinuses, accordingly, the mandibular canals of the jaw are as close as possible. In the known construction, the pressure is borne by the subperiosteal part of the implant body, and the intraosseous part serves only for vertical and transverse stabilization.
The relief of the bone is usually such that it does not allow lateral oscillations, where the presence of an intraosseous part of the body only complicates the construction and complicates the surgical intervention for its placement.
The object of the invention is to provide a dental implant that is universally applicable to any type of edentulousness involving more than one tooth, having a simple and lightweight construction, requiring quick and simple surgical intervention during placement.
We solved the problem by creating a dental implant, the body of which is made of a saddle-shaped frame with two end arches and intermediate arches, shaped as lateral inclined supports, to the common tip / common tips /, on which are built at least one neck and head. Of the implant. The level of the tops of the two end arches is lower than the level of the base of the neck of the head. The body of the implant we made as a casting of rhenium with a coating of titanium 99.9%. It is possible to move the position of the head asymmetrically with respect to the vertical axis of symmetry of the body.
The advantages of the invention are the following:
The dental implant has a simple and lightweight construction, allowing easy adaptation to the individual clinical case edentulousness in size, number of heads and their location symmetrically or asymmetrically to its vertical axis of symmetry to achieve maximum medical and biological effect. We place the implant as quickly and simply as possible by forming stabilizing grooves in the bone at a minimum area and depth without the risk of getting into the jaw cavities and postoperative complications. Also, the construction is universal for use for any type of edentulous, covering more than one tooth and is convenient to use in a combined system of supports, including other types of implants in the increasingly common complete edentulousness and at a younger age is treated by creating supports for fixed prosthetics, reflected for example in L / 2 /.
The implant of the present invention is particularly effective in combination with other types of root implants for the construction of a system of prostheses for prosthetics of a structure for a toothless jaw. In this case, we stabilize the prosthetic structure with distal support. The implant evenly distributes the chewing pressure over the entire jawbone, due to which its functional suitability is longer.
The invention we illustrate in more detail by an exemplary embodiment shown in the attached figures, in which: FIG. 1 is an axonometric view of the implant. FIG. 2 - the implant placed on a gypsum model of the jaw.
As shown in FIG. 1, the dental implant, object of the invention, has a body consisting of a frame of the saddle / 1 / with two end arches / 2 / and with formed intermediate arches as laterally inclined supports / 5 / to the common tip to which we connect the neck / 3 / and the head / 4 / of the implant. The number and configuration of the execution of the intermediate arches / 5 / are not limited and we decide on a case-by-case basis. An embodiment with more than one head is possible, and the position of the heads relative to the vertical axis of symmetry of the body can be both symmetrical and asymmetrical. The level of the tops of the two end arches / 2 / is lower than the level of the base of the neck / 3 / of the head / 4 /. The body we usually cast from the rhenium alloy by applying a 99.9% titanium coating.
In FIG. 2 shows the implant object of the invention placed on a gypsum model of a jaw. It rests on its two end arches / 2 /, located in stabilizing grooves / 6 /, which secure the implant against longitudinal movement. The difference in the level of the two end arches / 2 / and of the jawbone allows for bone growth above them.
The method of placement of the dental implant is as follows:
We make a mucoperiosteal lambo in the classic surgical way. We form two stabilizing grooves in the corresponding position with a corresponding bone cutter, and then we take an imprint of the bone with a silicone impression material for making the dental implant. We suture the wound and after 2 - 3 weeks with repeated surgical intervention the described construction of a dental implant is placed subperiosteally as the two end arches / 2 / are placed in the grooves stabilizing against longitudinal movement / 6 /. We suture the wound and after about 12 days, we can start making the prosthetic structure.
