Definitions
- the invention relates to medicine, in particular to navigational dental implantation, and can be used in the manufacture of individual rear-surgical templates used in the process of installing root-dental dental implants.
- the rear surgical template consists of a plastic base and guide sleeves.
- the guide sleeves are pressed into the plastic base of the rear surgical template according to the position of the planned implants.
- the position of the guide sleeves contains information about the location, depth and direction of the drilling axis of the bed in the jaw bone for implants.
- the guide sleeves are made of solid medical material (titanium, stainless steel, etc.), provide a high level of safety during the operation and reduce the time for it, and the implants installed with the help of the guide sleeves in the template will be in the optimal position, which will ensure their long and trouble-free operation.
- Guide sleeves are made mainly from titanium alloys such as the Ti-6A1-4V ELI.
- the central axis of the sleeve in the template coincides with the axis of the planned implant.
- the position of the sleeve axis depends on the length of the drill.
- Sleeves of different manufacturers differ in diameter, height and types of fixing spurs on the outer surface.
- currently used sleeves do not allow inside them to cool the drill during reciprocating movements in the process of drilling the patient's jaw bone.
- the present invention is to eliminate the disadvantages of standard guide sleeves and the creation of a guide sleeve with internal cooling (NVBO) for navigation dental implantation, which is part of an individual Rear-surgical template having a cylindrical shape with an axial hole, where the sleeve contains at least one channel Physio-dispenser irrigation hose for supplying cold water to the axial hole, which cools the sleeve and the outer surface of the drill, at least at least one opposite channel or a complete lateral window for diverting used water, at least one notch on the top edge in the shape of a rectangular triangle and a longitudinal groove located on the inner wall perpendicular to the cold water supply channel that communicates with it through the through hole.
- NVBO internal cooling
- the technical result of the invention is a more efficient cooling of the drill and sleeve, thereby preventing overheating of the jaw bone and reduced wear of dental instruments, while abundant and continuous washing inside the sleeve space reduces the level of wound contamination, i.e. penetration of microorganisms into the wound and metal shavings formed upon contact of the drill with the sleeve, and as a result, the implantation engraftment improves.
- the technical result is achieved due to the design of the NVBO, which optimally contains two channels: one channel leaves the vestibular side of the template, i.e. from the side where the cheek and lip of the patient are located, and the other channel comes out from the proper oral side of the template, that is, from the side where the patient's tongue and sky is located.
- An irrigation hose of a physiodispenser is connected to one of the channels to supply cold water to the outer surface of the drill, which reciprocates inside the sleeve in the process drilling the jaw bone of the patient.
- the opposite channel has a diversion function for heated and used water.
- the surface of the drill is continuously provided with cold and clean water.
- NVVO can be made in different versions: with a semi-lateral or full lateral window for more convenient access of a drill or other surgical instrument. With a full lateral window, a diversion channel is not required, since the lateral window itself performs this function.
- the wall of the sleeve can be made of various sizes and shapes.
- the outer wall of the sleeve with a lateral window can be made rectangular to prevent deformation of the inner wall.
- the sleeve is provided with a rim around the upper edge of the lateral window to prevent divergence of the edges.
- All HBVO variants have at least one notch in the shape of a right triangle on the upper edge, which is designed to prevent further movement of a specially designed implant driver - a tool for screwing the implant into the bone.
- the above implant driver is designed directly for work with the described variants of the sleeves. It has a special protrusion of the appropriate shape, which, when articulated with a recess on the sleeve, automatically stops the rotational movement of the implant driver, which prevents the implant from becoming too deep into the bone.
- the outer surface of the sleeve can be equipped with spurs of various shapes for reliable fixation in the template.
- the figure 1 presents the guide sleeve with internal cooling
- the figure 2 shows the guide sleeve with internal cooling with a semi-lateral window
- the figure 3 shows the guide sleeve with internal cooling with full lateral window; 4 shows a drill bit that has a cylindrical part in the middle;
- figure 5 shows a top view of the sleeve with internal cooling with a full lateral window with the groove shown on the inner wall;
- FIG. 6 is a side view of an inner-cooled sleeve with a full lateral window with a groove on the inner wall shown;
- FIG. 7 shows a tool specially developed for working with NVBO, with which the implant is screwed into the bone-implant-driver; 8 shows an implant driver with a protrusion and a VNVO with a corresponding notch;
- figure 9 shows the articulation of the protrusion of the implanter with the groove NVVO when screwing the implant clockwise into the bone.
- the claimed invention in various embodiments of its implementation allows to produce a guide sleeve with internal cooling (figure 1) mainly with two channels, where one channel (1), leaving the vestibular or proper oral side of the template, is attached to the irrigation hose of the dispenser for cold water supply, and the opposite channel (2), leaving the opposite side of the template, serves to drain warm used water. Cooling water is supplied from the channel (1) to the inner walls of the sleeve and the outer surface of the drill, which reciprocates inside the sleeve during the drilling of the patient's jaw bone.
- the guide sleeve with internal cooling is made with the possibility of its manufacture with a semi-lateral window (figure 2) mainly with two channels, where the channel (1) serves to supply cold water, and the opposite channel (2) serves for removal of warm used water.
- the guide sleeve with internal cooling made with the possibility of its manufacture with a full lateral window (fig.Z).
- NVVO with a complete lateral window contains a channel (1), which serves to supply cold water, but does not contain a discharge channel, since the discharge function of the channel itself performs lateral window. Thus, the used water can flow freely through the window, so the channel is not required.
- the NVBO (FIG. 1) and the NVBO with a semi-lateral window (FIG. 2) can be performed with either two or more than two channels for supplying and discharging water, if necessary, to carry out more abundant irrigation of the drill inside the sleeve.
- NVVO with semi-lateral and full lateral window are used in case of insufficient opening of the patient’s oral cavity during the operation, and are also intended for operation with drills that have a cylindrical part (4, FIG. 4) in the middle, similar to which is presented at https: // kolaydrill .com.
- All variants of the sleeves have a longitudinal groove on the inner wall (3, FIG. 1; FIG. 2; FIG. 3), which is perpendicular to the channel for supplying cold water (1, FIG. 1, FIG. 2; FIG. 3), wherein the channel communicates with the groove through a through-hole (FIG. 5; FIG. 6).
- the groove (3, Fig. 1; Fig. 2; Fig. 3) of the sleeve assumes a diverting function at the time the drill makes a reciprocating motion when the cylinder clogs the internal opening of the cold water supply channel (1, FIG. 1; FIG. 2; FIG. 3).
- All the described variants of the NVBO in contrast to the existing analogues, have at least one notch in the form of a right-angled triangle on the upper edge (5, FIG. 1; FIG. 2; FIG. 3).
- the recess is designed to prevent further movement of a specially designed implant driver (Fig. 7).
- the specified implanter designed directly to work with the described variants of the sleeves in the present invention.
- the HBVO in accordance with the present invention is made with the possibility of producing a spore of various form on its outer surface in order to securely fix the sleeve in the rear of the surgical gauge.
