Resumo: | OBJECTIVE: This study evaluated the effect of chemical polishing on the internal adaptation of complete denture bases fabricated with Veracril® resin and polymerized by either the conventional (C) or microwave (M) techniques. MATERIAL AND METHODS: Six groups (n=6/group) were tested: 1) C + no polishing (CO); 2) C + chemical polishing (CQ); 3) C + immersion in hot water at 75ºC (CW); 4) M + no polishing (MO); 5) M + chemical polishing (MQ); and 6) M + immersion in hot water at 75ºC (MW). Internal adaptation immediately after the polishing treatment and after 30 days of storage in water at 37ºC was evaluated by weighing a vinyl polysiloxane film reproducing the gap between resin base and metallic master model, using a precision scale. Data were analyzed by ANOVA and Tukey test and paired Student's t test, at a significance level of 0.05. RESULTS: No significant difference in immediate adaptation was found as a function of technique, polishing treatment, or interaction of technique/polishing. After 30 days, adaptation means (g) were: CO=2.46±0.32 a; CQ=3.40±0.23 d; CW=3.14±0.22 c; MO=3.23±0.37 c, d; MQ=3.41±0.47 d; MW=2.81±0.33 b (means followed by different letters are statistically different at alpha=0.05). All groups but group CO had significant increase of misfit over the tested period. CONCLUSION: The present results suggest that Veracril® resin denture bases submitted to chemical polishing had decrease of internal adaptation in 30 days, although immediate adaptation was not affected. |

CONCLUSION: The present results suggest that Veracril® resin denture bases submitted to chemical polishing had decrease of internal adaptation in 30 days, although immediate adaptation was not affected. OBJETIVO: Este trabalho avaliou o efeito do polimento químico sobre a adaptação interna de bases de próteses totais confeccionadas em resina acrílica ativada termicamente Veracril® polimerizada por técnica convencional (C) ou por microondas (M). MATERIAIS E MÉTODOS: Foram testados seis grupos (n=6/grupo): 1) C + sem polimento (CO); 2) C + polimento químico (CQ); 3) C + banho de água a 75ºC (CW); 4) M + sem polimento (MO); 5) M + polimento químico (MQ); e 6) M + banho de água a 75ºC (MW). A adaptação interna foi avaliada por pesagem em balança analítica de precisão de uma película de silicona de adição interposta entre base de resina e modelo-mestre metálico. A adaptação foi medida imediatamente após o polimento e após 30 dias de armazenamento em água a 37ºC. Os dados foram analisados por ANOVA e teste de Tukey, e por teste t de Student pareado, ao nível de significância de 0,05. RESULTADOS: Não houve diferença significativa na adaptação imediata em função do tipo de polimerização, do polimento ou da interação polimerização/polimento. Após 30 dias, as médias de adaptação (g) foram: CO=2,46 0,32 a; CQ=3,40 ± 0,23 d; CW=3,14 ± 0,22 c; MO=3,23 ± 0,37 c, d; MQ=3,41 ± 0,47 d; MW=2,81 ± 0,33 b (médias seguidas por letras diferentes diferem entre si, alfa=0,05). Todos os grupos apresentaram aumento significativo de desadaptação ao longo do tempo, com exceção do grupo CO. CONCLUSÃO: Os resultados sugerem que as bases de resina Veracril® submetidas a polimento químico apresentaram diminuição de adaptação interna em 30 dias, embora a adaptação imediata não tenha sido afetada.
