Esse artigo buscou demonstrar, através de um relato de caso clínico, a abordagem de levantamento de seio maxilar bilateral por duas diferentes técnicas, uma traumática via janela lateral e uma atraumática através da crista óssea, associadas à instalação de implantes osseointegrados. Paciente com 75 anos, gênero feminino procurou atendimento na clínica do Curso de Extensão em Implantodontia em uma universidade do Rio de Janeiro com quadro álgico em região de molares superiores. Após anamnese, exame clínico e análise da tomografia computadorizada, evidenciou-se extensa lesão de furca nos elementos 16 e 26, sendo indicada exodontia e reabilitação com implantes oseeointegrados. Ainda, devido à pouca altura óssea subantral, o levantamento de seio maxilar bilateral foi incluído ao plano de tratamento. No lado direito, foi realizada a técnica de Summers e no lado esquerdo a técnica da janela lateral associada ao uso de biomaterial sintético particulado e membrana de colágeno reabsorvível. A radiografia panorâmica de controle pós-cirúrgico demostrou o êxito das duas técnicas com adequada relação anatômica do enxerto e de ambosmplantes ao leito receptor. Assim, a cirurgia de elevação do seio maxilar com a concomitante instalação de implantes se mostrou um procedimento seguro, de boa previsibilidade e baixa taxa de complicações.

Introduction Considering the increased search for esthetic procedures, questions emerge about the maintenance and regression of color, especially regarding the need to restrict dark foods during bleaching procedures or their influence on the stability and effectiveness of the treatment. Objective To assess the influence of staining agents on tooth enamel during immediate bleaching treatment with 35% hydrogen peroxide. Material and method Sixty bovine teeth were divided into six groups (G) (n=10): G1: distilled water (control); G2: coffee; G3: cola soft drink; G4: wine; G5: mate tea; and G6: industrialized açaí. The samples were subjected to immediate bleaching using 35% hydrogen peroxide for 21 days (three applications of 15 minutes per session, every seven days) and pigment immersion between each session for 15 minutes. The color was assessed before starting bleaching and after 21 days, using a spectrophotometer. The data obtained were subjected to one-way ANOVA and heteroscedasticity analysis by the Welch and Brown-Forsythe tests. The Tamhane test was used for group comparison. Result The color change was visible to the naked eye, considering the mean ΔE in all groups tested was higher than 3.7. However, there was no statistical difference between the control group and the groups assessed. Conclusion The contact of staining agents on bovine tooth enamel did not affect the final result of the immediate tooth bleaching.

Oral rehabilitation with fully ceramic implant-supported prostheses is one of the treatment options that presents clinical longevity and patient satisfaction. However, complications regarding the chipping are reported in the literature. To reduce these problems, the use of monolithic zirconia is constantly suggested. Another option, not so reported, are the modifications in the final configuration of the cover ceramic. The design of the chosen materials is discussed. The choice of prosthesis type and gingival conditioning to achieve an adequate emergency profile is also described. This clinical report describes an aesthetic rehabilitation of the maxilla with all-ceramic prosthesis and application of the cover ceramic only on the buccal surface by PF-1 implant-supported.
