Resumo: | The osseointegrated implants were developed seeking to the rehabilitation of edentulous patients, and the initial protocol commended the placement of the implants on the healed alveolar bone. The healing of extraction socket was considered, therefore, one of the basic requirements for the establishment of the osseointegration. However, recently, studies have been demonstrating that the implants can be placed into sockets immediately after tooth extraction, presenting success rate similar to implants placed in healed bone. The purpose of this study was to evaluate the bone healing around implants placed into fresh extraction sockets, comparing the perceptual of bone-to-implant contact of cervical third with middle third of implants. In the present study 26 implants of IMZ™ system were placed into extraction sockets of the 3° e 4° premolars in mandibles of 4 dogs, without defined race. For histomorphometric analyses, accomplished 3 months after placement of the implants, each implant was divided in three parts (cervical, middle and apical thirds). The middle third was considered as control, since in this region, the implants presented in contact with bone on surgery moment. The cervical third was considered as the experimental area, because many times, did not exist bone-toimplant contact in this region, by the fact the coronal part of socket normally have a bigger diameter than implant. The apical third was discarded of the analyses, because great part of implants was placed into mandibular canal, without or with minimum bone contact. The osseointegration perceptual obtained in the middle third of implants was 33.39%, while in the experimental area this perceptual was 11.13%, and this difference was statistically significant. The present study demonstrated that, despite of clinically the spaces between coronal portion of implants and bone walls of socket presented clinically healing, the histomorphometric analyses revealed a smaller osseointegration perceptual at cervical third comparing with middle one, after 3 months to healing. |

Os alvéolos de extração cicatrizados eram considerados, portanto, um dos pré-requisitos básicos para o estabelecimento da osseointegração. Porém, nos últimos anos, estudos têm demonstrado que os implantes podem ser instalados nos alvéolos dentários logo após a exodontia, apresentando taxas de sucesso semelhantes à daqueles inseridos em rebordo ósseo totalmente remodelado. O objetivo deste estudo foi avaliar a cicatrização óssea ao redor de implantes instalados diretamente em alvéolos frescos de extração, comparando o percentual de contato ósseo do terço cervical com o terço médio dos implantes por meio de análise histomorfométrica sob microscopia óptica. No presente estudo 26 implantes do sistema IMZ® foram instalados nos alvéolos de extração dos 3° e 4° pré-molares inferiores de 4 cães, sem raça definida. Para a análise histomorfométrica, realizada após 3 meses da cirurgia de instalação dos implantes, cada um foi esquematicamente dividido em 3 partes (terço cervical, médio e apical). O terço médio dos implantes foi considerado como controle, uma vez que nesta região, os implantes apresentavam-se em contato com o tecido ósseo desde o momento da cirurgia. O terço cervical dos implantes era a região de interesse deste estudo e, portanto, considerada a área experimental, onde muitas vezes não havia contato do implante com o osso em função da porção coronal do alvéolo normalmente possuir um diâmetro maior que o implante. O terço apical foi descartado das análises deste trabalho, pois grande parte dos implantes, nesta região, encontrava-se dentro do canal mandibular, consequentemente sem, ou com muito pouco, contato ósseo. O percentual de osseointegração verificado no terço médio dos implantes foi de 33,29%, enquanto na área experimental foi de 11,13%, sendo esta diferença estatisticamente significativa (P<0,05). O presente estudo revelou que, apesar de clinicamente os espaços entre a porção coronal dos implantes e as paredes ósseas dos alvéolos apresentarem-se clinicamente cicatrizados, as análises histomorfométricas apresentaram percentuais de osseointegração menores nos terços cervicais dos implantes em comparação com os terços médios, após 3 meses de cicatrização.Submitted by Patricia Vieira Silva (patricia.silva@unigranrio.com.br) on 2016-09-27T19:04:44Z No. of bitstreams: 1 Dissertação de Mestrado em Odontologia - Fred Machado Freire.pdf: 10748902 bytes, checksum: 11437b1699c4c464c137f54806ecd2cf (MD5)Made available in DSpace on 2016-09-27T19:04:44Z (GMT).

The osseointegrated implants were developed seeking to the rehabilitation of edentulous patients, and the initial protocol commended the placement of the implants on the healed alveolar bone. The healing of extraction socket was considered, therefore, one of the basic requirements for the establishment of the osseointegration. However, recently, studies have been demonstrating that the implants can be placed into sockets immediately after tooth extraction, presenting success rate similar to implants placed in healed bone. The purpose of this study was to evaluate the bone healing around implants placed into fresh extraction sockets, comparing the perceptual of bone-to-implant contact of cervical third with middle third of implants. In the present study 26 implants of IMZ™ system were placed into extraction sockets of the 3° e 4° premolars in mandibles of 4 dogs, without defined race. For histomorphometric analyses, accomplished 3 months after placement of the implants, each implant was divided in three parts (cervical, middle and apical thirds). The middle third was considered as control, since in this region, the implants presented in contact with bone on surgery moment. The cervical third was considered as the experimental area, because many times, did not exist bone-toimplant contact in this region, by the fact the coronal part of socket normally have a bigger diameter than implant. The apical third was discarded of the analyses, because great part of implants was placed into mandibular canal, without or with minimum bone contact. The osseointegration perceptual obtained in the middle third of implants was 33.39%, while in the experimental area this perceptual was 11.13%, and this difference was statistically significant. The present study demonstrated that, despite of clinically the spaces between coronal portion of implants and bone walls of socket presented clinically healing, the histomorphometric analyses revealed a smaller osseointegration perceptual at cervical third comparing with middle one, after 3 months to healing. |
