[Two-cog (pi-shaped) dental implants and preclinical validation of their use]

Based on the results of statistical analyses, the authors validate the need in development of a new optimal design of implants for replacement of removed mandibular molars. Two-cog (P-shaped) dental implants are suggested, which have been patented. Study of their biomechanical characteristics by digital experiments using three-dimensional final element simulation demonstrated the efficiency of this design of implants, particularly for direct and early implantation and confirmed the adequacy and validity of the two-cogs implants.
