The present invention is related to the rehabilitation and restitution of the bone structural loss in the paranasal sinuses area, so that the loss of teeth, premolars and molars in both quadrants of the upper jaw can be rehabilitated, despite the severe collapse of bone structures, using the remaining bone to anchor in the antral area of the paranasal sinuses, using the internal cortical of paranasal sinuses and the external cortical of crestal area.
For thousands of years, humanity has sought to solve the need to recover the function and restitution of lost organs, developing innovative techniques and designs to supplement their life quality.
Dental implants are small pieces, usually made of titanium, that replace natural tooth roots. The discovery that titanium osseointegrated into the bone was a serendipity case (a lucky and unexpected discovery or finding).
It is worth mentioning that from this event to the present day, dental implant design has not changed, taking the mechanical principle of a cylindrical and conical metric thread lag-screw.
The benefit of this technology has had an absolute high impact regarding the quality of life, aesthetics, phonetics, self-esteem, digestion, and psyche of people, extending itself to the animal kingdom.
Before dental implants existed, dental rehabilitation was invariably performed in two ways: Removable prosthesis which, because they do not remain fixed in the mouth, become an invasive appliance to soft tissues (causing gum inflammation), hard tissues (causing bone loss), and teeth or molars where they are attached by means of clasps. Over time, all this together causes loss of vertical and horizontal dimension. With these appliances, the individual's esthetics, phonation, and digestion are compromised. Fixed prosthesis whose main disadvantage consists in lowering and carving adjacent pieces, that is to say, the dental pieces that will serve as anchorage to support one or more missing teeth.
Dental implants consist of placing a titanium root inside the bone, similar to a pin or screw by means of a surgical procedure.
The missing piece or pieces are anchored to the implant, completely avoiding the invasive circumstances of the aforementioned treatments. There are determining factors that prevent this type of treatment from being accessible to most of world's population.
The product becomes more expensive because it is managed as a state-of-the-art technology by the manufacturing countries, with an exaggerated price for the use of foreign patents, and countries like ours depend 100% on these companies, affecting the country's economy due to its importation.
Another factor would be implantology learning curve, since the practice of this specialty requires, in addition to a high academic knowledge, a skill to be developed because it is a design (the of the screw or pin) to be placed in a bone (living tissue) to achieve a primary stability (supreme anchorage) to ensure the success of the surgery.
At present, placing dental implants in the upper jaw and/or specifically in the paranasal sinus area when the patient has already lost teeth (premolars and molars) in one or both sides of the upper jaw for a long period of time, becomes a series of surgeries that requires the professional technical, surgical and academic knowledge beyond those common of general dentists, giving this practice a place within the advanced implantology.
Regarding the patient, all this results in onerous economic expenses, a series of postoperative care, and a complicated recovery period, with a noticeable decrease in the quality of life; without forgetting the series of postoperative care.
We must add the risk, which is undoubtedly the most important fact that exists (with a series of postoperative care and onerous financial expenses) that at some point the osseointegration of the implant or implants may fail and lead to fibrosis, that in place of osseointegration and, due to controlled and uncontrolled factors, the implant migrates into the sinus cavity or sinus antrum, this being extremely invasive, complicated and dangerous, which requires the intervention of different professionals such as maxillofacial, otorhinolaryngologist, and to hospitalize the patient for a major surgery, general anesthesia, operating room, recovery on the floor, etc.
Rehabilitation of bone loss and bone structure in people requires different implant surgical techniques in wide skeletal extensions. The present invention relates to such techniques and directly to the fixation and anchorage of prostheses in the upper jaw.
The present invention is related to the rehabilitation and restitution of the bone structural loss in the paranasal sinuses area, so that the loss of teeth, premolars, and molars in both quadrants of the upper jaw can be rehabilitated, despite the severe collapse of bone structures, using the remaining bone to anchor in the antral area of the paranasal sinuses.
It is worth mentioning that this design proposed for the present application will avoid the worrying fact of the accidentally dental implant migration to the paranasal sinuses, and at the same time make the placement of such attachments more friendly and less invasive, avoiding the two surgeries that are currently required for the rehabilitation of such segments.
The proposed design breaks with the universal paradigm of dental implants, because since their discovery until today, no substantial changes have been made.
In order that the invention may be better understood, there is a description below of the currently preferred embodiments of the invention, in which reference will be made to the attached drawings, which are an integral part of the present descriptive memory, and in which:
This invention is described based on a preferred embodiment of the Oroantral Prosthetic Attachment in which:
It is to be understood that the invention is not limited in its application to the construction details and component arrangement set forth in the accommodation presentation and illustrated in the drawings.
It is noted, unless otherwise provided, that all technical or scientific terms used herein have the same meaning as commonly held by persons having knowledge of the arts of the invention. The methods and examples provided herein are illustrative and are not intended to be limiting.
As can be seen in the Figures, the Oroantral Prosthetic Attachment is made up of the following elements; the clamping screw (1), the anchor (2), the clamping nut (3), plug screw (4) and the truncated cone (5).
The Oroantral Prosthetic Attachment is placed in the remaining bone to anchor in the antral zone of the paranasal sinuses using the internal cortical of the paranasal sinuses and the external cortical of the crestal zone. This makes the implant not to migrate to the paranasal sinuses and the saving of previous bone regeneration surgeries in the paranasal sinuses.
Each one of the constituent elements of the Oroantral Prosthetic Attachment is illustrated in one or more of the figures of the drawings and will be described in the following.
