Purpose: of this paper is present a new approach to modelling and design the low cost mono-block dental implants based on the integration of the computer aided techniques. This approach provides the automation of the design process of the mono-block dental implants. Design/methodology/approach: The approach used to develop the modelling and design of the mono-block dental implants are based on the parametrization of the main geometric features of the implants. This approach allows to generate several designs of the implant with different configurations respect to the dimensions, forms and tolerances. Findings: The findings are focused on two main topics. The first one is the minimization of the manufacturing cost and time based on the manufacture process automation. The second one is the integration, in the same informatics platform, of the design, analysis and manufacturing environment. Research limitations/implications: The implications are focused on the development of a new design of mono-block dental implants. One of the main features of this design is associated to the reduction of the surgical stage and their simplification respect to other commercial implants. Practical implications: The main outcomes and implications of this research is the design of a low cost dental implant. This solution is implemented to assist the social programs of oral health. Originality/value: The originality of this research is the design of a new model of mono-block dental implant. The structure of this implant improves the mechanical properties; reduce the manufacturing cost and the surgical complications.
