"IMPLANTATO LAMINARE COSTITUITO DA UN CORPO LAMINARE CON SFINESTRATURE" . "LAMINAR IMPLANT CONSISTS OF A LAMINAR BODY WITH SPLINESTRATURE".
RIASSUNTO SUMMARY
Impiantato laminare con sfinestrature del corpo laminare chiuse da tutti i lati, le quali occupano al massimo 1/3 della superficie. La base del corpo laminare ? delimitata da una linea continua (figura 1). Laminar implant with openings in the laminar body closed on all sides, which occupy a maximum of 1/3 of the surface. The basis of the laminar body? bounded by a solid line (figure 1).
DESCRIZIONE DESCRIPTION
L'invenzione ? relativa ad un impiantato laminare metallico costituito da corpo laminare, collo e montanti da inserire in una incisione della mascella ed il cui corpo laminare presenta una pluralit? di sfinestrature. The invention? relating to a metal laminar implant consisting of a laminar body, neck and uprights to be inserted in an incision of the jaw and whose laminar body has a plurality of of windows.
Le gole dei montanti poggiano sulla spalla del corpo laminare, mentre il lato opposto del corpo laminare rivolto alla mascella viene designa to come base. La lamina stessa presenta sfinestrature. Negli impiantati cono sciuti la base ? interrotta in parte nel piano della lamina, cosicch? parti dei lati o ali pendono dalla spalla liberamente verso il basso o formano assieme alla spalla un telaio della lamina, le cui sfinestrature sono distribuite arbitrariamente sulla superficie della lamina. The grooves of the posts rest on the shoulder of the laminar body, while the opposite side of the laminar body facing the jaw is designated as the base. The foil itself has cutouts. Do you know the base in implants? partially interrupted in the plane of the lamina, so that? parts of the sides or wings hang freely downwards from the shoulder or together with the shoulder form a lamina frame, the slots of which are arbitrarily distributed on the lamina surface.
A tali impiantati manca, a causa dell'assenza di statica, la sta bilit? interna, cosicch? non sono da escludere deformazioni elastiche e permanenti della lamina sotto la pressione di masticazione. Ci? rende difficile la crescita di ossa attraverso le cavit?, rispettivamente le ossa esistenti vengono rapidamente riassorbite. I tessuti che crescono attraverso cavit? grandi hanno una percentuale pi? elevata di tessuto molle ed il nucleo o la parte interna dell'osso rimanente viene sostituito da un tessuto connettivo-molle. Pertanto la desiderata stabilit? non viene conseguita nemmeno dopo lungo tempo. Due to the absence of statics, these implants lack stability? internal, so that? Elastic and permanent deformations of the lamina under chewing pressure cannot be ruled out. There? makes it difficult for bones to grow through the cavities, respectively existing bones are rapidly reabsorbed. Tissues that grow through cavities large have a higher percentage? soft tissue elevation and the core or core of the remaining bone is replaced by connective-soft tissue. Therefore the desired stability? it is not achieved even after a long time.
Gli assorbimenti dell'osso causati da questi movimenti si manifestano in particolare in prossimit? del montante che attraversa la gengiva. The absorption of the bone caused by these movements occurs in particular in the vicinity? of the post that crosses the gingiva.
Inoltre in tali impiantati non stabilizzati si hanno, in caso d? sollecitazione, divaricazione delle ali libere, come pure forze torcenti e flettenti se l'impiantato appoggia sulla sua lunghezza su tratti o porzio ni di sostanze ossee di differente resistenza. Furthermore, in such non-stabilized implants there are, in case d? stress, spreading of the free wings, as well as twisting and bending forces if the implant rests along its length on portions or portions of bone substances of different strength.
Ali o lati liberi degli impiantati noti possono causare forti assorbimenti ossei cos? forti, da far scomparire completamente il supporto osseo. Wings or free sides of the known implants can cause strong bone absorption. strong, to make the bone support disappear completely.
Mediante esami istologici si ? stabilito che attraverso piccole cavit? cresce in proporzione molta pi? sostanza osseadura che tessuto connettivo molle, rispetto a ci? che avviene nelle cavit? pi? grandi. Through histological examinations yes? established that through small cavities? grows in proportion much more? bone substance that soft connective tissue, compared to there? what happens in the cavities? pi? large.
Il compito che sta alla base dell'invenzione ? quello di realizzare un impiantato di per s? stabile, sul quale si accumula ed attraverso il quale cresce la maggior quantit? possibile di sostanza ossea. The task underlying the invention? to create an implant in itself? stable, on which it accumulates and through which the greatest quantity grows? possible of bone substance.
Questo compito viene risolto secondo l'invenzione grazie al fatto che le sfinestrature costituiscono complessivamente al massimo 1/3 della superficie del corpo laminare, la cui base ? chiusa nel piano della lamina da una linea cont?nua ininterrotta. Un tale impiantato laminare ? stabile di per s? n particolare se le sfinestrature del corpo laminare sono delimitate lateralmente da puntelli, che sono larghi almeno 0,8 mme portano o alla base oppure alla spalla del corpo laminare, cio? quindi non ad altri puntelli -o ai bordi laterali - e le rendono stabile. This task is solved according to the invention thanks to the fact that the openings constitute a maximum of 1/3 of the surface of the laminar body, the base of which? closed in the plane of the lamina by an uninterrupted continuous line. Such a laminar implant? stable in itself? In particular, if the openings of the laminar body are delimited laterally by props, which are at least 0.8 mm wide and lead either to the base or to the shoulder of the laminar body, that is? therefore not to other props - or to the side edges - and make them stable.
In questo caso la forza agente sul montante dovrebbe essere guidata tramite il collo, attraverso un puntello disposto in un prolungamento del collo, fino alla base. In this case the force acting on the upright should be guided through the neck, through a prop arranged in an extension of the neck, up to the base.
Grazie a ci? la forza pressione di masticazione agente tramite il montante si distribuisce uniformemente sull'intero corpo laminare e sulla sua base Thanks to there? the chewing pressure force acting through the upright is uniformly distributed over the entire laminar body and its base
La parte inferiore o fondo della base ? smussata, ad esempio arrotondata e non pi? affilata a scalpello come nei noti impiantati da inserire a percussione. L'incisione della mandibola viene eseguita preferibilmen te con una sega circolare. Secondo un ulteriore concetto dell'invenzione, la spalla degli impiantati destinati alla mascella superiore, designazione tecni ca u (superiore) ?, in particolare nella zona del nodo o tubero radicale, larga quasi il doppio della spalla degli impiantati destinati alla mascella inferiore, designazione tecnica L (inferiore). Le larghezze sono all'incirca U fino a 2,5 mm L 1,2-1, 4 mm. Ci? ? dovuto al fatto che nella mascella supe riore sono presenti ossa spugnose, che richiedono una maggior azione a cuneo. Le spalle dei corpi laminari possono essere munite di cavit? estendentisi in lunghezza per poter inserire attrezzi a forma di scalpello per l'applicazione degli impiantati. The bottom or bottom of the base? blunt, for example rounded and not more? chisel-sharp as in the well-known implants to be inserted by percussion. The incision of the mandible is preferably performed with a circular saw. According to a further concept of the invention, the shoulder of implants intended for the upper jaw, technical designation u (upper)?, In particular in the area of the root node or tuber, almost twice as wide as the shoulder of implants intended for the lower jaw, designation L technique (lower). The widths are approximately U up to 2.5mm L 1.2-1.4mm. There? ? due to the fact that spongy bones are present in the upper jaw, requiring greater wedge action. Can the shoulders of the laminar bodies be provided with cavities? extending in length to be able to insert chisel-shaped tools for the application of implants.
