El propósito de esta investigación es proponer el desarrollo de un nuevo proceso para la obtención de sockets de miembro inferior basado en el uso de tecnologíasde adquisición de datos, modelado 3Dymanufactura aditiva. Previamente, se identificó la viabilidaden latécnica del uso de escáneres de bajo costo en el desarrollo de un socket apartir de la reconstrucción 3D;medianteelcaso de estudiode unparticipante con amputación transfemoral y socket cuadrilateral, donde se valoró el proceso por técnica tradicional comparado con el proceso basado en tecnologías de manufactura digital. Planteando así un modelo de integración de tecnologías (Ingeniería Inversa, CAD e impresión 3D) y estableciendo una basepara estudios en diferentes aplicaciones médicas. Igualmente, se observó la utilidad del modelo frente a la portabilidad de las tecnologías, la gestión de cambios y la reducción de materias primas y desechos;comparándolo con la técnica tradicional.

The main purpose of this research was oriented to generate a structured modelfrom an organizational vision to the definition and development of precise osteosynthesis prosthesis. Implants were adapted to the Colombian population anthropometry allowing fracture reductions and craniofacial defects corrections based on technologies for specific patients. This research was developed taking into account the first three PLM stages: Imagination, definition, and realization. Procedures, stages, roles, and activities that take part in the design and pre-surgical planning were identified for the patient-specific implants PSI,carried out through a study case. It was established as a definition model for design and fabrication process of patient-specific implants (PSI).It was possible that technology included in a collaborative workflow wherein the roles which intervene in the design process and the pre-surgical planning were related. The abilityto design implants for specific patients and surgical guides was obtained different pathology situations including face trauma.According to the PLM strategy for designingcustom implant, it would be possible to buildinnovation capabilities.With those, an organization could generate a collaborative workflow integrating stages, roles, activities, applying technology and local human resource. Further work related to the subject is necessary to enhancethe process by iteration and improve the clinical cases management.

Ti6Al4V dental implants were manufactured to be inserted into bone tissue specimens of human cadaver jaw and similar densities of bone substitute specimens Sawbone ® normalized like bone density D2 type. Then were measured the insertion torque data recording to adjust the implant at samples. Data from the test were used in simulations based on the finite element method. Through the elastic strain criteria, it was known the strain values less than 0,4% of the elastic strain at the bone implant interface. Based on outputs case study, the values of insertion torque to be applied to insert implants surgery are recommended.
