Abstract
OBJETIVO: Avaliar comparativamente a força de tração (F) determinada com a utilização de parafuso excêntrico em placas do tipo compressão dinâmica larga (DCP-L). MÉTODOS: Foram utilizadas três placas de tipo DCP-L de quatro fabricantes nacionais, todas em aço inoxidável austenítico ASTM F 138, e instrumentais disponíveis nas caixas de 4.5mm. As placas foram fixadas a dois corpos de prova sintéticos de polietileno e a força de tração foi obtida pela utilização de parafuso de 4.5mm, introduzido em furo excêntrico, realizado com instrumentais específicos de cada fabricante. Os resultados foram obtidos por uma máquina servo-hidráulica BME 2000 160/AT, Brasválvula. Os implantes foram divididos em grupos. (Fab. I, II, III, IV). Os testes foram interrompidos após atingir uma força de aperto do parafuso excêntrico de 5 N. RESULTADOS: O grupo I apresentou média de Força máxima (F Max.) 80.58 N; grupo II: F Max. 81.63 N; Grupo III: F Max. 36.32N; Grupo IV: F Max. 37.52N. Utilizando a Análise de Variância de Krukal-Wallis (ANOVA não paramétrica), sendo p= 0,05 existe diferença significativa na força máxima entre os grupos (p = 0,039). CONCLUSÃO: As placas DCP-L do grupo II apresentaram maior força (N) com fixação da placa utilizando parafuso excêntrico. Nível de Evidência: Nível III, estudo analítico.
OBJECTIVE: To comparatively evaluate traction force (F) determined with the use of the eccentric screw in large compression dynamic plates (DCP-L). METHODS: Three DCP-L plates were used, from four national manufacturers, all in austenitic stainless steel ASTM F 138, and instruments available in boxes of 4.5mm. The plates were attached to two specimens of synthetic polyethylene, and traction force was applied using a 4.5mm screw inserted into the eccentric hole, using instruments specific to each manufacturer. The results were obtained by a servo-hydraulic machine BME 2000 160/AT, Brasválvula. The implants were divided into groups. (Fab I, II, III, IV). The tests were stopped after reaching a pinch force of the load screw of 5 N. RESULTS: Group I had a mean peak force (F Max) of 80.58 N; Group II: F Max 81.63 N; Group III: F Max 36.32N; and Group IV: F Max 37.52N. Using Krukal-Wallis Analysis of Variance (ANOVA non-parametric), where p = 0.05, there was a significant difference in maximum strength between the groups (p = 0.039). CONCLUSION: Plates DCP-L of group II showed greater strength (N) with plate fixation using the eccentric screw. Level of Evidence: Level III, analytical study.
