Definitions

  • This utility model belongs to the field of dental instruments, more specifically, it refers to a dental applicator coupled to a specific mandrel and a dental applicator coupled to a universal mandrel already on the market, both forming a set that is fitted into a handpiece or low rotation contra-angle - enabling the rotational movement of the tool used to apply various substances in dental adhesive procedures.
  • Dental applicators consist of a rod, the end of which comprises non-absorbent fibers resistant to abrasion and solvents, characterized by keeping the solution in suspension until it is applied to the teeth, avoiding waste of material.
  • a micro applicator consisting of: a body that is adapted at its end for connection to a rotating instrument (low rotation turbine /handpiece/contra angle); a shaft extending from the body; a core with tiny polyamide fibers.
  • the document proposes a solution for the standardization of the active application of adhesive systems to the dental substrate and the insertion of a method for the adhesive restorative procedure, whether in coronal or root dentin.
  • the body, rod and core form a single piece of injected polypropylene.
  • an intracoronal bristle brush for preparing a dental cavity, comprising a plurality of bristles and a dental bur with a shaft adapted to be received by a handpiece and a second end to receive the plurality of bristles.
  • the plurality of bristles emanates uniformly from an axial hole within the second end, the diameter of the intracoronal bristle brush being substantially uniform along its entire length so that the brush bristles can penetrate an internal surface of a tooth cavity .
  • Another objective of the patent is to propose the optimization of the application of adhesive procedures on enamel and dentin due to the greater interaction of adhesive materials with the tooth structure, through an active and rotating application.
  • Yet another objective of the patent is to propose a functional manufacturing improvement, considering that the proposed applicators are shorter than those proposed in the prior art, and, therefore, characterize an environmental production advantage in terms of the use of a smaller quantity of material, as well as a reduction in production costs.

  • Figure 1 B represents a variation of the applicator consisting of a universal mandrel already on the market (2) equipped with a female fitting portion (24) with the same diameter as the mandrel shank (2).
  • the adhesive applicator portion (3) is made separately and made of polymeric material, the length of which is shorter than those provided integrally by the prior art.
  • Figures 2A and 2B detail the mandrel (2) which comprises a central rod (21), a conventional coupling portion (22), which will be coupled to the low rotation handpiece (or counter angle) which it works as a turbine driven by compressed air, which is used by the dentist, and a female fitting portion (23, 24).

  • FIGS 3A and 3B detail the adhesive applicator (3) which comprises a male fitting portion (31, 32), which will be coupled to the female fitting (23, 24) of the mandrel (2), respectively; a rod (33); and a brush (34) made of non-absorbent fibers resistant to abrasion and solvents.
  • the male fitting portion (31, 32) optionally comprises a polygonal profile so that the fitting between applicator (3) and mandrel (2) is more efficient and safe, and can be carried out dynamically during the clinical procedure, preventing the dentist needs to change the entire applicator tool (1).
  • the fitting portion (32) can optionally be equipped with a reduction in diameter, which provides an improvement between the interface of the applicator fitting (3) in the mandrel (2), so that the fitting occurs with interference between the surfaces, favoring the connection between the parts.
  • the rod (33) of the applicator (3) optionally, has a conical shape, becoming thinner at the end that comprises the brush (34) - providing more versatile handling to the specificities of the tooth structure.
  • the fibers that make up the brush (34) are extremely fine, regular and have different shapes - and can be used for different materials used in adhesive procedures.
  • Figures 4 and 5 detail the set: mandrel (2) and adhesive applicator (3) which demonstrate the functional improvement proposed in the patent: the fact that the applicator (3) is detachable from the mandrel (2).
  • Figure 4 illustrates in exploded view the engagement of the mandrel with a female socket (23) with a larger diameter than the rod and the applicator with a male socket.
  • Figure 5 illustrates in exploded view the coupling of the universal mandrel with female fitting (24) with the same diameter as the mandrel and the applicator with male fitting and diameter reduction.
  • Figures 6A, 6B, 6C and 6D illustrate variations in the shape of the brush (34) of the adhesive applicators (3) with a recessed male fitting (32) - Figure 6A representing a variation of the brush (34) in short cylindrical shape, Figure 6B a variation of the brush (34) in long cylindrical shape, Figure 6C a variation of the brush (34) in spherical shape and Figure 6D a variation of the brush (34) in conical shape.
  • Figures 7A, 7B, 7C and 7D illustrate the shape variations of the brush (34) of the adhesive applicators (3) with male fitting (31) - Figure 7A representing a variation of the brush (34) in cylindrical shape short, Figure 7B a variation of the brush (34) in long cylindrical shape, Figure 7C a variation of the brush (34) in spherical shape and Figure 7D a variation of the brush (34) in conical shape.
  • Figure 8 illustrates the low rotation (AO) handpiece (or contra angle) which works as a turbine driven by compressed air, whose end has a chamber (MA) where the mandrel object of the patent is coupled ( Fig. 2A) and the universal mandrel (Fig. 2B), to which the adhesive applicators (Fig. 3B and 3A) will be attached, also objects of the patent.
