Definitions

• mini-pillars may be straight-type (single longitudinal axis) or angled or inclined (with at least two longitudinal axes), depending on the position and conditions of the location where the implant will be positioned.
• the construction of the mini abutments also depends on how the prosthesis is placed at the free end of the mini abutment, varying basically between models for cemented prostheses and models for prostheses screwed into the mini abutment.
• an angled mini abutment and a corresponding prosthetic component system capable of reducing the probability of bacterial accumulation by applying an optimized interface between abutment and implant, this morse cone interface; and for a pillar comprising a more anatomical shape (smooth format with no sharp edges), especially in the transmucosal region, favoring the conformation of the gingiva.
• One object of the present invention is therefore to provide a single body angled mini abutment according to the features of claim 1.
• Figure 2 shows a top view of the mini-pillar of figure 1;
• Figure 3 shows a side view of the mini-pillar of figure 1
• Figure 4 shows a front view of the mini-pillar according to the invention
• Figure 5 shows a side view of the mini abutment according to the invention
• Figure 6 shows a rear view of the mini abutment according to the invention
• Figure 8 presents an x-ray of the patient's mouth, showing the minimum bone thinning required for use of a prosthetic system according to the invention.
• Figure 9 presents an x-ray of part of the mouth of a patient, already rehabilitated, in which several prosthetic systems according to the invention were used.
• the single body 100 basically divides into a front (PF) and a rear (PP) part, having a vertical axis (EV) and an axis (El), shown in Figure 3.
• the prosthetic interface region 110 basically comprises a central through-hole 1 1 1 parallel to the vertical axis EV of the single body 100, a bore with internal thread 12 parallel to the inclined axis (El) of the single body (100), a convex edge (113) surmounting a frustoconical upper interface (118), which widens towards a transition zone (115) leading to a seat (16), annular free surface perpendicular to the inclined axis (El), wherein said seat (116) at its outer periphery passes through another transition zone (117) to a transition mantle (18), also annular, but concentric with the inclined axis (El).
• the transmucosal region (120) comprises a variable diameter along its height and comprises, basically, at the front (PF), a convex transition front ray (121), which passes to a frontal free surface ( 122) which in turn passes through another concave transition radius (123) which extends until it meets the interface region with the implant (130).
• the transmucosal region 120 basically comprises a transition back edge 125, which opens into a rear free surface 126, which extends until it encounters a radius (127) and to the interface region with the implant (130).
• the transition front radius (121) may range from a minimum of 0.2 mm to a maximum of 32 mm, the transition radius (123) may range from a minimum of 0.2 mm to a maximum of 10 mm and the radius (127) may range from a minimum of 0.2 mm to a maximum of 20 mm.
• the transmucosal region (120) has transition radii (121, 123 and 127) defining smooth curvatures along the body of the angled mini-pillar, so as not to conform edges, tips or ridges alive.
• transition radii 121, 123 and 127) defining smooth curvatures along the body of the angled mini-pillar, so as not to conform edges, tips or ridges alive.
• a major advantage of the mini abutment of the present invention is here noted, since it will be in direct contact with the soft tissue of the gingiva and will mold it to the surface shape of its transmucosal region.
• the gum being a soft and sensitive tissue, benefits from the soft shape that keeps it less susceptible to small fissures that can result in the reduction or contraction of this tissue - which is not welcome in these cases.
• the interface region with the implant 130 basically comprises a frustoconical portion 131, a transition zone 132, a cylindrical portion (not shown) and a mouth (134). Eventually, as shown in the appended figures, said cylindrical portion may receive an indexing region (140).
• said indexing region 140 may comprise, indexing elements 141, for example, a polygonal element with faces parallel to the vertical axis (EV) of the single body (100), so as to index positions by means of specific rotation angles depending on the number of faces of the polygonal indexing element (141). It is to be noted that other forms of indexing may be used, without prejudice to the technical effect of the mini abutment according to the invention.
• the single body (100) of the angled mini-pillar significantly reduces the regions that may eventually serve to accumulate and create bacteria, making the prosthetic assembly provided with an angled mini pillar according to the invention more hygienic and aseptic than the similar known to the state of the art, aiding in the promotion of an effective bacterial seal.
• the angled mini-pillar is provided with free surfaces throughout its structure, but in particular again in the transmucosal region (120) with surfaces intersection angle equal to zero (0 Q ) and with no visible lines on the surface.
• a prosthetic component system according to the present invention is a system comprising at least:
