Description
"ATTACHMENT PILLAR FOR REMOVABLE DENTAL PROSTHESIS WITH SELF-DIRECTED CONNECTION, MANUAL WRENCH AND TORQUE WRENCH
THEREOF"
Technical domain
The present application relates to an attachment pillar for removable dental prosthesis, specifically a Self-Directed Connection Pillar with Four Retentions (SDCP-FR) .
Background
Currently, in the field of removable dental prosthesis attachment and within medical and dental practice in the application of such products, 2 types of difficulties arise which definitely influence the prosthesis functionality and hence the benefit/usefulness of the product: 1 - on the one hand, some patients' expectations regarding the performance of the attachment are greater than those which effectively come to be observed; this is because the expectation is always that the prosthesis shall be as adjusted as possible; however, the joint between the attachment and the prosthesis ultimately never comes to be as adjusted as expected by the patient; 2 - then, on the other hand, in senior patients or patients with motor disability of the upper limbs, due to either physical disabilities or chronic disease, placing the dental prosthesis in the mouth can cause a very troublesome traumatic situation, which involves anxiety and disturbance; in fact, for this group of patients, given the lack of skill or physical agility, it becomes difficult to find the joining point of the attachment with the prosthesis; and since not immediately finding the joining point, they persist until they obtain the stabilization of the retention device; moreover it turns out that the difficulty is such that they end up only being able to achieve placement with the help of another person who places the prosthesis inside their mouth.
Thus, there is a need for a more capable product which provides, not only stability and placement ease, but also an improved retention of total or partial prostheses.
The development of Self-Directed Connection Pillar with Four retentions (SDCP-FR) arises from such need, as well as from the importance of oral health condition which affects life in general. SDCP-FR is a novel product, since going beyond the current industrial technique, wherein no solution to overcome the difficulty in placing a prosthesis is available.
To date there is no product providing four retentions and which, at the same time, ensures an attraction-type capture of the SDCP-FR pillar (1) with the SDCP-FR retentive means (3), thus allowing support and stability to the dental prosthesis .
Summary
The present application is related to an attachment pillar for removable dental prosthesis with self-directed connection comprising a pillar (1), a capsule (2), and a retentive means (3), wherein the pillar (1) and the retentive means (3) have a magnetic means (M) on the inside .
In one embodiment, the pillar has four retentions by means of two curves on the outside thereof (15) (16), a void (17) and the magnetic field (18) created between the magnetic means of the pillar and the magnetic means of the retentive means .
In another embodiment, the pillar has a small hole which drains saliva.
In yet another embodiment, the pillar and capsule material is titanium and the retentive means material is nylon.
The present application also relates to a manual wrench and a torque wrench for implementing the attachment pillar for removable dental prosthesis with self-directed connection comprising a magnetic means therein.
General Description
The SDCP-FR is composed of a pillar (1), a capsule (2), and a retentive means (3), wherein the pillar (1) and the retentive means (3) have a magnetic means inside.
The SDCP-FR has four retentions, summarized in the following terms: the pillar (1) has two curves in its
[outer] shape, so that a double retention occurs, also having a void that will provide a third retention; the fourth retention is obtained by means of the magnetic field created between the pillar (1) and the retentive means (3)
(they shall attach through the attraction phenomenon caused between the magnetic means inside them) - Figure 2.
Within the existing void in the pillar there is still a small hole that drains saliva - Figures 6 and 8. The magnetic attraction created between the pillar (1) and the retentive means (3) causes the dental prosthesis to be immediately self-directed - Figure 1.
The psychological aspect in oral rehabilitation is important. By ensuring the attraction-type capture of the pillar (1) with the retentive means (3), this product provides firm support and unwavering stability to the dental prosthesis; the vitality of this reciprocal action enhances quality of life and well-being to patients.
Specifying, by using SDCP-FR, obtaining a more secure attachment of the dental prosthesis is made possible, preventing the prosthesis from being released from the respective fittings, which hinders chew action and causes irritation to the gum, in addition to the consequent pain, inconvenience and discomfort that such a situation involves; moreover, in the presence of a partial dental prosthesis, a less secure prosthesis may cause damage to natural teeth since the teeth supporting the partial prosthesis are at higher risk of developing problems arising from increased pressure and movements; so, and in the context of partial prosthesis, by reducing the movements, it is important to bear in mind that SDCP-FR helps protect the natural teeth of the patient.
The properties / materials of SDCP-FR components are:
- Pillar (1) : Titanium and Magnetic means;
- Capsule (2) : Titanium;
- Retentive means (3) : Nylon and Magnetic means.
Two wrenches - a manual wrench (5) and a torque wrench (6) are further proposed, which, with an outer field and inner field, fit perfectly into existing voids in the pillar (1), fixing it to the dental implant. In order to eliminate the risk of accidents or complications, a magnetic means is inserted on the inside thereof which, in addition to a perfect fit, potentiates the phenomenon of attraction between the pillar (1) and the wrench being used, preventing the pillar from falling or becoming detached while being handled - Figures 32 and 33.
Also, since the type of retention shall always be assessed by the odontological health care professional, and bearing in mind the particular case needs, some intermediate attachment solutions are further proposed which are detailed in Figures 14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29 and 30.

Figure 35 illustrates a replica of the pillar to be worked in laboratory (12) . One pillar replica is subsequently placed on the printing sample so that the working model is later created in laboratory to produce the dental prosthesis . Description of the embodiments
Referring to the figures, some embodiments shall now be described in more detail, which are not however intended to limit the scope of the present application.
The SDCP-FR is thus composed of a pillar (1), a capsule (2) and a retentive means (3) . The pillar (1) and retentive means (3) have a magnetic means inside. It has four retentions: the pillar (1) has two curves in its [outer] shape, so that a double retention occurs, having a void that will provide a third retention; the fourth retention is obtained by means of the magnetic field created between the SDCP-FR pillar (1) and the SDCP-FR retentive means (3) - Figures 1 and 2.
The capsule (2) has a curved shape inside, in order to predict the existence of any strength applied onto the implant by masticatory movements, so that some freedom is created in its movement relative to the retentive means (3), which is embedded in the pillar (1) . The latter is attached to a dental implant, thereby leaving some freedom for rotary motion so that the capsule does not disengage from the pillar (1) .
The capsule (2) has three ribs to annul the effects of horizontal forces applied onto the dental prosthesis, which prevents the capsule (2) from being released from the dental prostheses; these ribs also have some cuts to annul the possibility of a capsule rotating within the dental prosthesis .
The type of retention shall always be assessed by the odontological health care professional taking the individual case needs into account. Therefore, for situations requiring intermediate attachment, the following solutions are further proposed:
The retentive means (7) is herein composed of three retentions: an outer retention, an inner retention and a third magnetic retention, which are detailed in Figures 14, 15 and 16;
The retentive means (4) is herein composed of two retentions: an outer retention, and a second magnetic retention, which are detailed in Figures 17, 18 and 19;
