Evaluation of design parameters of eight dental implant designs: A two-dimensional finite element analysis

Abstract: The findings in this study suggest that the filleted and rounded square thread with an angulation of 30° showed highest stresses and strains at the implant-bone interface. The trapezoidal thread transmitted least amount of stresses and strains to the cortical bone than did other models.

“…The development of a more universally applicable implant in most clinical cases could represent a major breakthrough in implant techniques. In line with this purpose and in order to fill the deficiency gaps observed in clinical practice, researchers together with the industries have consistently proposed changes in the macro geometry of the screws, changes that promote greater surface area and contact between bone/implant, with increased primary stability and the reduction of bone‐anchor related failures …”

“…In line with this purpose and in order to fill the deficiency gaps observed in clinical practice, researchers together with the industries have consistently proposed changes in the macro geometry of the screws, changes that promote greater surface area and contact between bone/implant, with increased primary stability and the reduction of boneanchor related failures. 9,10 Current research has focused on creating more profitable surgical and prosthetic protocols for the treatment of partial and total edentulism. In parallel, investigations strive for new implant projects to increase primary stability and achieve greater clinical predictability in complex cases.…”

“…No geral, o design do implante pode ser classificado de acordo com sua macroestrutura, relacionada ao tamanho, desenho, número, profundidade das espiras e tipo de conexão protética e microestrutura, associada ao material de constituição, morfologia e tratamento de superfície (Abuhussein et al, 2010;Chang et al, 2012;Desai et al, 2012).…”

“…O desenho quadrado da rosca, em oposição ao padrão em forma de "V", minimiza as tensões geradas no osso circunjacente, pois gera uma transmissão de carga ao longo do corpo do implante, para comprimir o osso, menor do que as roscas em "V". Além disso, geram menor força cisalhante e dissipam a carga axial por meio de forças compressivas, enquanto implantes rosqueados em forma de "V" transmitem a carga por meio de uma combinação de compressão, tração e cisalhamento (Geng;Tan;Liu, 2001;Misch;Strong;Bidez, 2008;Desai et al, 2012). Quando um parafuso é inserido no leito receptor, o tipo de força aplicada na interface osso/implante pode influenciar a taxa de osseointegração.…”
