Description
Descrizione Description
La presente invenzione ha per oggetto un dispositivo intercambiabile utilizzato in campo dentale atto a definire e modificare lo spazio di movimento dell’articolazione temporo-mandibolare , nel modo piu’ individuale . The present invention relates to an interchangeable device used in the dental field designed to define and modify the movement space of the temporomandibular joint, in the most individual way.
La classificazione migliore e' quella che divide le articolazioni in due classi , sinartrosi e diartrosi , quella presa in esame e' la sinartrosi in quanto in queste articolazioni e' situato tra le parti ossee tessuto fibroso o cartilagineo il quale si unisce intimamente alle superfici ossee . The best classification is the one that divides the joints into two classes, synarthrosis and diarthrosis, the one taken into consideration is synarthrosis as in these joints it is located between the bony parts fibrous or cartilage tissue which is intimately joined to the bony surfaces .
Sono noti strumenti come articolatori incernierati in un determinato punto che possono svolgere movimenti programmabili a valore medio senza una effettiva individualita’ , There are known tools such as articulators hinged at a certain point that can perform programmable movements at an average value without effective individuality,
tuttavia dato gli intimi rapporti delle ossa tra di loro che determinano posture e tragitti soggettivi e individuali e’ risultato di rilevante importanza creare un dispositivo capace di ricreare la stessa superficie o cavita’ all’interno del quale scorre un’altro oggetto di forma diversa ma definita da misure certe atte a riprodurre in modo preciso quello che in natura avviene . Il suddetto dispositivo , a differenza di quelli regolabili gia esistenti , ha la qualita di however, given the intimate relationships of the bones between them that determine subjective and individual postures and journeys, it is of great importance to create a device capable of recreating the same surface or cavity inside which another object of a different shape but defined by certain measures designed to accurately reproduce what happens in nature. The aforementioned device, unlike the already existing adjustable ones, has the quality of
poter definire in modo matematico lo spazio volumetrico entro cui avvengono i movimenti mandibolari registrati tramite uno strumento di rilevazione come la fotogrammetria . to be able to mathematically define the volumetric space within which the mandibular movements recorded by means of a detection tool such as photogrammetry take place.
Lo scopo dell’invenzione e’ quello di poter ricreare una situazione posturale adeguata The purpose of the invention is to be able to recreate an adequate postural situation
tenendo conto dei normali processi di usura muscolo scheletrici che il tempo modifica . taking into account the normal processes of musculoskeletal wear that time changes.
Oggetto della presente invenzione e’ un oggetto 4 contenente uno spazio volumetrico 2 all’interno del quale si muove un’altro oggetto 3 , lo spazio volumetrico, puo’ definirsi una sorta di contenitore all’interno del quale e’ stato ricavata una cavita’ 5 che simula le cavita’ gleniodee o fossa glenoidea , ad essa si appoggia un’altro oggetto di forma varia e calibrata che simula il disco articolare 1 , al quale si appoggia un utensile 3 di forma rilevata o sferica che simula il condilo . The object of the present invention is an object 4 containing a volumetric space 2 inside which another object 3 moves, the volumetric space, can be defined as a sort of container inside which a cavity has been obtained. 5 which simulates the glenioid cavities or glenoid fossa, another object of varied and calibrated shape leans on it, which simulates the articular disc 1, on which a tool 3 with a raised or spherical shape that simulates the condyle leans.
La cavità del contenitore 5 e’ il risultato di strumenti di misura e produzione che analizzano la forma e il movimento della mandibola , attraverso software si realizzano superfici e oggetti sotto forma di file 3D , il disco articolare diventa stampabile o fresabile in base alle tecnologie migliori del momento , ed è quindi possibile riprodurre nel miglior modo possibile l’oggetto in questione . The cavity of the container 5 is the result of measurement and production tools that analyze the shape and movement of the jaw, through software we create surfaces and objects in the form of 3D files, the articular disc becomes printable or millable according to the best technologies of the moment, and it is therefore possible to reproduce in the best possible way the object in question.
Semplificando immaginiamo un cubo 4 all’interno del quale si muove una sfera , interposto tra 4 e 3 c'e' il disco articolare 1 , nell'insieme la forma corretta di questi tre elementi crea un movimento articolare nuovo . Simplifying, let's imagine a cube 4 inside which a sphere moves, interposed between 4 and 3 there is the articular disc 1, overall the correct shape of these three elements creates a new joint movement.
Il principio di acquisizione del movimento di un articolazione del corpo e la sua replica dello spazio volumetrico entro cui avvengono i movimenti e' esteso a tutte le articolazioni del corpo umano, come ad esempio l’articolazione della spalla del gomito dell’anca della mano del ginocchio della caviglia del collo del piede e di tutte le articolazioni intervertebrali . The principle of acquisition of the movement of a joint of the body and its replication of the volumetric space within which the movements take place is extended to all the joints of the human body, such as the shoulder joint of the elbow of the hip of the hand of the knee of the ankle of the instep and of all intervertebral joints.
L’oggetto della presente invenzione puo’ essere utilizzato su tutte le articolazioni scheletriche opportunamente riprodotte tramite ad esempio Tac Cone Beam e modificate adeguatamente in modo da poterne sfruttare il movimento individuale . The object of the present invention can be used on all skeletal joints suitably reproduced through, for example, Tac Cone Beam and modified appropriately so as to be able to take advantage of their individual movement.
Si desidera la tutela brevettuale in quanto l’oggetto in questione puo' essere utilizzato in campo medico per riprodurre e ripristinare movimenti dell'A.T.M. nel settore dentale e i movimenti di qualsiasi anatomia del sistema articolare . Patent protection is desired as the object in question can be used in the medical field to reproduce and restore movements of the A.T.M. in the dental sector and the movements of any anatomy of the joint system.
