Abstract

Lower dental prosthesis, of the removable type, which consists of a dental prosthesis (4) for the lower jaw to which at least two fastening tabs or flaps (5) are added, prolonging the lower internal area of the adapter element, which is placed on the gum and maxillary bone and acts as a support for the dental pieces, the holding fins (5) adapt laterally to the wall inclined downwards and towards the outside of the lower jaw and recess of the submandibular fossae (2), said fins have a rim or bulge at their lower end (6).

Description

DESCRIPTION

Lower dental prosthesis

Field of the Invention

In removable dentures.

State of the art

Currently there is a lot of difficulty in holding the total lower prostheses, when there are no fixed parts. It is solved with powders, creams and adhesive pads, or by placing implants or hook points in the lower jaw. The present invention avoids such drawbacks.

Object of the invention and advantages

Obtain and facilitate the fixation of the lower dental prosthesis in a simple and economic way.

Avoid having to apply products or implants to fix it.

Facilitate cleaning, as it can be removed more regularly. Facilitating your hygiene.

Avoid untimely movement when talking, eating, etc.

Facilitate its use by older people and more daily disassemblies.

Having prostheses of different sizes, useful for underdeveloped countries.

Problem to solve

The untimely displacement during the opening of the mouth, during meals, when speaking, etc., facilitating dental hygiene.

Description of the Invention

The lower dental prosthesis, of the removable type, of the invention, consists of a dental prosthesis for the lower jaw to which at least two fins or holding tabs are added, an extension of the lower internal area of the adapter element, which is placed on the gum and maxillary bone and acts as a support for the dental pieces, the holding fins adapt laterally to the wall inclined downwards and towards the outside of the lower jaw or submandibular fossae, these fins have a rim or bulge at their lower end ( 6) It avoids damaging the user's gums.

The holding fins can be rigid, flexible, fixed, removable by tongue and groove or fixed with screws. Inside, the fins can carry a flexible metal plate or sheet of reinforcement, this can run internally through the upper area of the denture. Due to the flexibility of these fins, models of different sizes could be manufactured and tested with reference standards, being only necessary to adapt the joint between the upper and lower teeth. Noble materials or alloys will be used with these and especially that are incompatible.

More detailed description of an embodiment of the invention

The invention, figure 5, shows an embodiment of the prosthesis on the lower mandibular area of the face and jaws (7), the lower jaw bone (1), the recess of the submandibular fossa (2), where the curved end (6) of the holding flap (5), object of the invention and extension of the lower internal area of the adapter element, which is placed on the gum and maxillary bone and supports the dental pieces of the dental prosthesis (4), the fins adapt laterally in the recess of the submandibular fossae (2). Figure 1 shows the lower mandibular bone (1) and the recess of the submandibular fossa (2) in the internal area.

Figure 2 shows the lower mandibular bone (1), the recess of the submandibular fossa (2) and the inclined wall (3) of the lower mandibular bone.

Figure 3 shows the lower dental prosthesis (4), the inner holding flap (5) and its curved end (6).

Figure 4 shows the lower prosthesis (4) and the lower mandibular area (7).

Figure 6 shows the lower jaw area of the face and jaw (7), the lower jaw bone (1) with its inclined inner wall (3), towards the lower area, where the curved end (6a) is adapted and hooked on the holding flap (5), attached to the lower dental prosthesis (4) by means of the tongue and groove (8).

Figure 7 shows the lower mandibular area of the face and jaw (7), the lower jaw bone (1), the recess of the submandibular fossa (2), where the curved end (6) of the holding flap is hooked ( 5), object of the invention and extension of the lower internal area of the adapter element, which is placed on the gum and maxillary bone and supports the dental pieces of the dental prosthesis (4), the interior of the fin carries a flexible metal reinforcing plate or sheet (9).

Figure 8 shows the lower area of the lower mandibular bone (1) with the prosthesis (4) with the holding tab (5) in the recess of the submandibular fossa (2). The holding flap can occupy or extend parallel to the entire molar area.
