Definitions
- the present invention is in the field of dentistry, scanning abutments, in particular scanning abutments with chain for associated impressions, in particular differentiated scanning abutments and elastic hybrid helical resin chain for impressions with intraoral scanners.
- the digitization pillars do not present a macro morphology that differentiates their various faces, often without morphological elements that allow the correct superposition of images between the digitization pillars and in the surrounding tissues, makes difficult the digitization process, that is, it is difficult to differentiate the several digitization pillars, when there are more than one among them, because they are the same and there is nothing that differentiates them or references between them.
- the digitization pillars designated in the technical area of Scan Bodies (SB), and in this document as digitization pillars, having not found a better translation, currently existing on the market present, in the overwhelming majority of cases, regular cylindrical or polyhedral bodies with few morphological irregularities.
- the present invention concerns differentiated scanning pillars (2), since a modification to its macro geometry is proposed, and it is also complemented by an elastic helical chain to be used in full-arch impressions in order to facilitate and improve the accuracy of fingerprints in dental implant prostheses.
- Figure 1 representation of several existing state-of-the-art digitization pillars (1), currently available on the market, being represented by regular cylindrical or polyhedral bodies with few morphological irregularities.
- Figures 2 and 3 Representation of a situation of state-of-the-art digitalization abutments (1), for a situation of impression of contiguous implants (figure 2) or in arches (figure 3), to visualize the difficult and doubtful precision the final impression because the presence of digitization pillars, without teeth between them, or for a better referencing, being noticeable how these pillars do not facilitate the scanning process.
- Figure 4 Representation of a situation of state-of-the-art scanning pillars (1), where it is clear that they do not allow the correct superposition of images between them and in the surrounding tissues, making the scanning process difficult.
- Figures 5 and 6 Representation of the present invention where the digitizing pillar (2), the beveled top (4) and the salient macro geometric shape (3) are identified, the gutter (5) and the hole (6) are also visible where the screw for inserting the part / implant to be digitized is inserted.
- Figures 7 and 8 Representation of the three-dimensional references for a digitization with the new digitization pillars (2).
- Figure 9 Representation of a semi-rigid elastic helical chain (7) with quadrangular links (8).
- Figure 10 Representation of a semi-rigid elastic helical chain (7) with circular links (8) with a diameter 1 mm smaller than the diameter of the digitizing pillar (2).
- FIG 11 Representation of the helical chain (7) with circular links (8) on the digitization pillars (2).
- FIGS 13, 14, 15 and 16 - Representation of the helical chain (7) with circular links (8) on the digitization pillars (2) with simulation of insertion in soft tissues.
- Figure 17 Representation of the application of the helical chain (7) complementary to digitalization in a way conventional when used in conventional prints, rigid "per se” and photopolymerizable.
- the present invention relates to a differentiated scanning pillar (2) for dentistry, which has a cylindrical or polyhedral body, beveled (4) on top of the body and has salient macro geometric shapes (3) and distinct between pillars (2) in use, these shapes being preferably in a number equal to or greater than three, and around the body of the digitizing pillar (2).
- the scanning pillar (2) also has a gutter (5) or throttling, located in the upper third of its body, and this gutter (5) or throttling has a perimeter smaller than the perimeter of the scanning pillar body by approximately 1 mm.
- the fixation of the digitizing abutment (2) to the part to be digitized, implant or abutment is performed using a screw with the same characteristics as the digitizing abutments currently on the market and known to experts in the field, which is inserted into the hole ( 6).
- the three-dimensional references which are nothing more than the salient macro geometric shapes (3) of the pillars of scanning (2) allow for greater fluidity and accuracy of impressions of adjacent dental implants with intraoral (IOS) scanners, compared to state-of-the-art scanners (1) without any differentiation between them, since there is difficulty and irregular accuracy of implant scanning in edentulous arches due to the existing distance between the digitizing abutments and the little morphological exuberance and/or mobility of the soft tissues.
- IOS intraoral
- a semi-rigid elastic helical chain (7) formed by a plurality of links (8) of quadrangular or circular shape with a diameter of 1mm smaller than the diameter of the digitizing pillar (2).
- These links (8) of the helical chain (7) have an offset of rotation of 20 degrees clockwise or counterclockwise in relation to the previous link (8).
- the links (8) of the helical chain (7) can be solid - solid color or, alternatively, transparent, hollow and filled with a photopolymerizable resin, of high precision, this second embodiment allows photopolymerization of the chain after positioned resulting in a rigid structure.
- This helical chain (7) together with the digitization pillars (2) allows an efficient intraoral digitization, which constitutes a system for intraoral digitization.
- the use of the digitization pillars (2) object of the present invention in conjunction with the complementary helical chain (7) of the digitization object of the present invention makes the process more efficient and rigorous, since the gutter (5) existing in the upper third of the digitizing pillars (2) allows the easy and correct positioning of the complementary digitizing chain, together with the beveled top (4) for sliding the helical chain (7) for positioning it to the rail (5).
- the complementary digitizing helical chain (7) may also be applied in a conventional manner when used in conventional prints, rigid "per se” photopolymerizable or as a support for acrylic resin or composite, self or photopolymerizable.
