No presente estudo in vitro, avaliou-se a quantidade de torque gerada pelos torquímetros: Nobelpharma de 20 e 32 N/cm (Nobel Biocare / Sweden) (1A e 1B), Torque Driver 3I de 20 e 32 N/cm (Implant Innovations / USA) (2A e 2B), Torque-Lock em 20 30 N/cm (Intra-Lock / USA) (3A e 3B) e Dyna de 20 e 30 N/cm (Dyna Torq / USA) (4A e 4B), em dez parafusos UCLA titânio (3I implants innovations REF UNIH / USA T). Mediu-se a quantidade de torque necessária para o afrouxamento do parafuso após o torque com cada torquímetro, utilizando-se um medidor analógico de torque (TOHNICHI BTG60CN / JAPAN). Os resultados mostraram diferenças estatisticamente significantes nos torquímetros 1A e 2A com os torquímetros 3A e 4A. Houve também diferenças estatisticamente significantes entre os torquímetros 1B e 2 B, assim como entre os torquímetros 3B e 4B. Alem disso, encontraram-se diferenças no torque produzido e o torque programado nos torquímetros 3A e 3B, e 4A e 4B, concluindo-se que os torquímetros eletrônico Nobelpharma e 3I de 20 e 32 N/cm geram a quantidade de torque para a qual são programados enquanto que os torquímetros Torque Lock e Dyna de 20 e 30 N/cm não geram a quantidade de torque para o qual são programados.Downloads
