Abstract: Objective: To rapidly construct bone-implant complex finite element model series using worksheet-driven CAD and finite element analysis software. Methods: The alveolar ridge and implant models were constructed by CAD software separately. Based on those models, the CAD models of different compositions of cancellous and compact bone and different implants were built and assembled. Electronic form software was utilized to drive the change of dimension in the process. All the models were imported into finite element analysis software and converted to finite element models after installation of different parts in the CAD software. Results: A total of 300 finite element models for different alveoli-implants were obtained through activating different versions of models. The models were of high quality and had no interference with each other. Conclusion: Our modeling method is rapid and highly effective. The series of models basically covers all types of alveoli,which provides a tool for studying the biomechanical characters of implants.
