Description
DISPOSITIVO PARA OSTEOGÊNESE VIA ESTÍMULO ELÉTRICO OSTEOGENESIS DEVICE THROUGH ELECTRIC STIMULUS
O presente pedido de patente descreve um implante dentário, cuja disposição construtiva é capaz de estimular eletricamente a osteogênese, e consequentemente acelerar a osseointegração' do implante. Uma porcentagem significativa das reabilitações bucais ocorre utilizando- se implantes dentários. Os implantes dentários são constituídos por biomateriais, inertes, inseridos em perfurações realizadas no tecido ósseo. Estes implantes atuam como a porção radicular de um elemento dentário. Posteriormente à instalação do implante dentário, é realizada a colocação de uma prótese sobre o mesmo e o paciente tem restabelecida a função de estética e de mastigação nesta área. The present application describes a dental implant, whose constructive arrangement is able to electrically stimulate osteogenesis, and consequently accelerate osseointegration 'of the implant. A significant percentage of oral rehabilitation occurs using dental implants. Dental implants are composed of inert biomaterials inserted into perforations made in bone tissue. These implants act as the root portion of a dental element. After the implantation of the dental implant, a prosthesis is placed on it and the patient has restored the aesthetic and chewing function in this area.
Branemark foi o idealizador desta técnica e descreveu pela primeira vez o termo osseointegração como sendo o contato intimo estrutural e funcional entre a superfície do implante e o osso (U.S Pat. 292,362). Um dos fatores imprescindíveis para se obter sucesso em implantes dentários é que este exerça adequadamente as funções mastigatórias. E para que um implante dentário seja funcional é necessário haver osseointegração. O tempo que se precisa para que os implantes se osseointegrem vai depender principalmente da capacidade de cicatrização de cada individuo, das características do implante utilizado e da técnica cirúrgica realizada. Levando-se em consideração esses fatores, se determinou que o período médio necessário para se colocar os implantes é de 6 o Branemark was the creator of this technique and first described the term osseointegration as the intimate structural and functional contact between the implant surface and bone (U.S Pat. 292,362). One of the essential factors to be successful in dental implants is that it properly performs the chewing functions. And for a dental implant to be functional, osseointegration is required. The time required for implants to osseointegrate will depend mainly on the healing capacity of each individual, the characteristics of the implant used and the surgical technique performed. Taking these factors into consideration, it was determined that the average period required to place the implants is 6 o
meses na maxila e de 3 meses na mandíbula, aproximadamente. months in the maxilla and 3 months in the mandible, approximately.
Este tempo de espera muitas vezes representa um grande inconveniente, especialmente para o paciente que tem que aguardar este período para receber a prótese definitiva. Uma das maneiras para se reduzir este tempo de espera seria
acelerar a neo-formação óssea. Existem duas formas possíveis para se realizar este fenómeno. Uma é por meio de forças físicas, que podem ser mecânicas, elétricas e sônicas. A outra forma é por meio de substâncias químicas, como a utilização de fatores de crescimento e outros moduladores do metabolismo ósseo. Com a redução do tempo necessário para a osseointegração, a prótese sobre implante poderia ser instalada em menos tempo. This waiting time is often a major drawback, especially for the patient who has to wait for this period to receive the final prosthesis. One of the ways to reduce this waiting time would be to accelerate bone neo-formation. There are two possible ways to accomplish this phenomenon. One is through physical forces, which can be mechanical, electrical and sonic. The other way is through chemicals such as the use of growth factors and other bone metabolism modulators.
