Description

PREFABRICATED BAR PROSTHETIC DEVICE INTRODUCTION

001 This Utility Model Patent descriptive report concerns a Prefabricated Bar Prosthetic Device, from now on called Prosthetic Device, which is intended for immediate installation on dental implants, made of surgical stainless steel, in articulated modules.

002 This Prosthetic Device consists of a prosthetic screw, single and double fixation pins, precision lock, articulated parts or modules with three, four and six holes, and can be used in any dental implant system, in dental arches that have two or more implants, and also comes with a template whose function is to direct the installation of implants - in this case for edentulous or toothless arches.

APPLICATION FIELD

003 The field of application of this Prosthetic Device refers to the area of Dentistry, more specifically to the sectors of Prosthesis and Implant Dentistry.

GOAL

004 This Prosthetic Device's main purposes are to serve as a metallic structure for fixing the teeth in the prosthesis on implants; Decrease the clinical and laboratory time for making the protocol prostheses, as well as reducing the cost of making the prostheses.

PROBLEMS TO SOLVE

005 As is common knowledge among specialists in the field of Implantology, dental implants are used to replace the absence of one or more dental roots, resulting from tooth extraction or loss, whereas dental prostheses are used to replace the absence of dental crowns and can be installed over dental implant posts.

006 The term dental or dental protocol (or protocol bar) is used to designate a type of dental prosthesis installed in edentulous dental patients, as an alternative to dentures, it is therefore a more comfortable, safe and functional type of fixed prosthesis, and can still be placed in the right place and installed on the upper teeth, lower teeth or both, correctly reconstructing and completely rehabilitating the oral functions.

007 The conventional system of dental protocol requires complex planning and involves a laborious system that requires specific technical knowledge from the dentist both in the area of implantology and in the area of prosthesis, that is, it requires the dentist to be a specialist in implants and/or prostheses.

008 In addition, in the conventional system of dental protocol, the Surgeon-dentist performs the stages of manufacturing the prosthesis, which include molding the patient's mouth and teeth, then sending it to a professional prosthetic technician for making in wax and for the metal casting of the protocol bar.

009 The conventional system for creating a dental protocol, with regard to dental implants, requires the dentist to perform the surgical installation of the implants and, additionally, monitor the patient until the osseo-integration process of the implant into the alveolar bone , which can last about four months.

010 Once the time for bone integration has elapsed, the dentist will be able to make the prosthesis on the installed implants, starting with the molding (a procedure that provides a mold of the patient's mouth/dental arch, with specific material for this purpose) which will be sent to the prosthetic laboratory.

011 In the prosthetic laboratory, the conventional dental protocol will be made in wax, later it will be cast in metal and adapted so that it can be screwed into the patient's mouth, on the implants previously installed and osseo-integrated.

012 This whole process entails several trips to and from the prosthetic laboratory and the time to complete the work is approximately thirty days, in addition to representing a very high cost for the dentist and the patient.

013 Therefore, all the time invested in the conventional system for the preparation of a complete dental protocol, which includes the installation of implants, preparation and installation of prostheses, can reach five months.

TECHNOLOGICAL PROGRESS

016 This Device is characterized by being a prefabricated prosthetic device for immediate installation on dental implants, fixed with a key from the Universal Prosthetic Kit, made of surgical stainless steel in articulated modules, it can be used in any dental implant system in dental arches that with two or more implants, it also comes with a template whose function is to direct the installation of the implants - in this case for dental arches without the presence of implants.

017 The procedure for installing a dental or dental protocol, that is, the placement of this type of dental prosthesis installed in edentulous dental patients, is widely performed in the areas of implant dentistry and dental prosthesis, as it serves as an alternative to dentures.

018 The main characteristic of this Prosthetic Device is the fact that it is prefabricated, that is, it is already pre-made and available in different sizes and measurements, which means that this Device does not need the casting phase mentioned in the conventional system since its system is already ready, the dentist just has to choose the size and model of the prefabricated protocol bar.

019 Another differential of this Prosthetic Device is that it can be used by any Dental Surgeon professional, of any specialty or even by general practitioners, in addition to dispensing with the presence of a prosthetic technician at the time of installation in the patient's mouth.

020 Another great advantage of this product is the possibility of using it in different prosthetic planning profiles, such as in prosthetic protocols with four or more implants.

021 Through the use of this Prosthetic Device, the prostheses can be tried on and positioned in the patient's mouth and installed immediately, that is, on the same day and right after the surgery for placement of the implants, or you can wait up to forty-eight hours later. In cases of patients who already have bone-integrated implants, the prostheses can be made within up to two days.

MODEL DESCRIPTION

023 As can be seen from the benefits mentioned in the Technological Advancement and in the description of the figures that accompany and form an integral part of this report, this Prosthetic Device (1) is characterized by being a prefabricated prosthetic device, of immediate installation on dental implants, made of surgical stainless steel, in articulated modules, and can be used in any dental implant system, even in dental arches that have two or more implants.

024 This Prosthetic Device (1) may be attached to dental implants through prosthetic screws (2) with a single pin (3), when it is an implant without the presence of adjacent dental prostheses or double pin (4), when there is the need for articulation with adjacent dental prostheses or articular modules of the Device itself (1).

025 When there is a need to articulate the joint modules of the Prosthetic Device (1), represented in this Report by the pieces with three holes straight (6) and curved (7), piece with four holes (8) and piece with six holes (9) , this articulation is made by means of the precision lock (5), which literally locks the modules, the prosthetic screw (2) and the double pin (4) to guarantee the stability of the system and the correct positioning of the Protocol (1) without the risk of carrying out a slinging movement over the dental arch.

026 The joint modules (6), (7), (8), (9) are connected to each other through the prosthetic screw (2), double pin (4) and precision lock (5) and this whole system is positioned over the implants and the dental arch.

027 After installing the Prosthetic Device (1) on the dental arch and the patient's implants, the dental prostheses can be placed in their respective beds, as a replacement for the missing teeth.

028 This Prosthetic Device (1) comes in a variety of sizes, that is, different measurements (three or more holes) and part models (straight and curved) and, for this reason, it can be installed immediately after implant placement surgery or within a period of up to forty-eight hours after.

CONCLUSION

029 It can be seen from everything that has been described and illustrated that this is a Prefabricated Bar Prosthetic Device, which fits perfectly within the rules governing the Utility Model Patent, deserving the requested privilege.
