Resumo: O objetivo deste estudo foi avaliar as alterações dos tecidos periimplantares, ao redor de implantes instalados em diferentes profundidades em relação à crista óssea, e sob protocolos de reabilitação protética convencional e imediato. Cinco cães receberam trinta implantes, três por hemi-mandíbula (seis por cão), na região dos quatro pré-molares inferiores que foram extraídos 90 dias antes. Cada região foi divida pelos subgrupos convencional (protocolo convencional, instalação da prótese 120 dias após os implantes) e imediato (protocolo imediato, instalação da prótese 1 dia após a cirúrgia de implantes). Os implantes foram inseridos em três profundidades diferentes: ao nível (ao nível do rebordo ósseo), -1 mm (1 mm apicalmente à crista óssea) e -2 mm (2 mm apicalmente à crista óssea). Após acompanhamento por 45 dias da reabilitação instalada foi realizada avaliação clínica e radiográfica e, os dados foram analisados estatisticamente (p< 0.05). A posição do tecido marginal (PTM) não foi alterada pelo protocolo de instalação, e sim pelo nível de inserção da junção implante-conector protético (JIC) em relação a crista óssea (BC). A reabsorção da BC em função do nível de inserção de JIC foi relativamente uniforme para os diferentes grupos. Estes achados sugerem cautela ao posicionar a JIC de implantes apicalmente à BC. / Abstract: The aim of the present study was to evaluate changes in tissues around dental implants inserted in different levels in relation to crestal bone (BC) under early and delayed loading conditions. Thirty implants were inserted in five mongrel dogs were used in this study, from which, the lower premolars were removed, and 90 days after, in one side, three dental implants were inserted (Delayed subgroup, implants installed 120 days before loading) in three different levels in relation to crestal bone (Bone Level, Minus1 and Minus2 groups), and three implants were inserted on remain ridge (Early subgroup, implants were loaded 48 hours after installed). The metallic prostheses were installed in both sides and preserved for 45 days. The clinical and radiographic analyses were performed. Data was submitted to statistics, under a 5% level of significance. The load conditions did not interfered on the position of marginal soft tissues (PTM), those changes evaluated because of the insert level of the implant-abutment junction (JIC) in to BC. The BC resorption was similar in all types of insertion levels of the implants. The present finds suggest caution on insertion of the implant in an apical position level in relation to BC. / Orientador: Elcio Marcantonio / Coorientador: Elcio Marcantonio Junior / Banca: Walter Martins Junior / Banca: Luis Antonio Borelli Barros / Mestre
