Prótese auricular é dentre as próteses faciais, a que se propõe a restaurar artificialmente ou aloplasticamente as lesões totais ou parciais da orelha. A retenção da prótese auricular pode ser mecânica, adesiva ou implanto-retida, assim o uso de implantes osseointegráveis para retenção de próteses auriculares tem trazido benefícios na estabilidade. Diferentes sistemas de retenção têm sidos utilizados com especificidades em relação às características na retenção, indicação e limitações. O presente trabalho teve como objetivo avaliar o comportamento mecânico de três sistemas de retenção de próteses auriculares quando submetidos à ciclagem mecânica. Doze modelos de resina acrílica com dois implantes instalados distando 20 mm entre si foram obtidos e divididos em três grupos, estes foram considerados como fatores de estudo: I - Barra-clipe (Sistema INP® - São Paulo - Brasil); II - Magneto (Metalmag® - São Paulo - Brasil ) e III - Ball/O-ring (Sistema INP® - São Paulo - Brasil). Cada grupo foi composto por quatro amostras, que foram submetidas ao teste de ciclagem mecânica de remoção e inserção (f = 0,5 Hz) para determinar a resistência à tração. A máquina servo-hidráulica MTS 810-Flex Test 40 (Eden Prairie, MN- USA) foi utilizada para realizar a ciclagem, com um deslocamento de 2.5mm e uma velocidade de 10 mm/s. Os valores da força de retenção foram obtidos em sete tempos (Inicial, 540, 1080, 1620, 2160, 2700 e 3240). Os dados foram comparados utilizando o teste Kruskal Wallis no programa SPSS 18.0. Os resultados foram considerados estatisticamente significativos para valores de p<0.05. O grupo retido pelo sistema barra-clipe apresentou maior força de resistência à tração (29,61 N) com diferença estatisticamente significativa quando comparado com o grupo retido pelo sistema ball/o-ring (9,41 N) e com o sistema com magnetos (8,62 N). Os grupos com retenção promovida por magneto e pelo sistema ball/o-ring diferiram com significância estatística somente para a tração inicial, que se mostrou maior no sistema ball/o-ring (p<. 05). Ao finalizar o teste de ciclagem o sistema barra-clipe garantiu maior retentividade, os sistemas avaliados apresentam força de resistência à tração compatível com o uso clínico e não tiveram fraturas dos componentes durante a avaliação de simulação de três anos de inserção e remoção / Abstract: Auricular defects are generally caused by ablative cancer surgeries, malformations or traumas. Auricular prosthesis is among the facial prosthesis used to restore artificially or alloplastic the partial or total lesions that effects of the auricular. The auricular prosthesis retention can be mechanical, adhesive or implant-supported. Therefore the use of osseointegrated implants for the retention of auricular prosthesis have brought benefits regarding stability, also different retained auricular systems have been used to show the differences between retention, display and limitations. This study aimed to evaluate the mechanical behavior of 3 retained auricular prosthetic connections when submitted to a mechanical cycling test. To conduct the present study, twelve acrylic resin models with installed implants positioned parallel at 20 mm apart were obtained and divided into three groups according to their retention system with four samples in each group. Three retained auricular prosthesis systems implant-supported: I - Bar-Clip system (INP® System - São Paulo - Brazil); II - Magnet System (METALMAG Ltda® - São Paulo - Brazil) and III - Ball/O-ring system (INP® System - São Paulo - Brazil) were considered as study factors. Each of the samples were submitted to the pull-out test (f = 0,5 Hz) to determine its tensile strength. The mechanical cycling test was performed using the servo-hydraulic machine MTS 810-Flex Test 40 (Eden Prairie, MN- USA) that had a 2.5mm shift at a 10 mm/s velocity. The retaining strength for each of the samples were obtained at 7 intervals: 1st - Initial cycles, 2nd- 540 cycles, 3rd- 1080 cycles, 4th- 1620 cycles, 5th 2160 cycles, 6th 2700 cycles, and, finish interval 3240 cycles. Kruskal-Wallis test was used to compare the differences in tensile strength and statistical analysis was performed using SPSS 18.0 for Windows, p values ?0.05 were considered significant. The tensile strength for the group retained by the bar-clip system (29,61 N) was higher with statistically significant difference when compared to the group retained by the ball/o-ring system (9,41 N) and magnets system (8,62 N). The groups retained by the magnets system and the ball/o-ring system differed with statistical significance only for the initial traction, which was higher for the ball/o-ring system (p?0,05). At the end of the cycling test, the bar-clip system ensured greater retentiveness. The evaluated systems showed a tensile strength compatible with the clinical use and no fractures of the components during the simulation of three years of insertion and removal were observed / Mestrado / Cirurgia e Traumatologia Buco-Maxilo-Faciais / Mestre em Clínica Odontológica
