The clinical significance of dental implants, including both natural and artificial intraosseous supporting structures, and the problems pertaining to the consistence of teeth and implants is determined by the necessity to ensure their systematization and adequate choice bearing in mind the agreement between their specific design and functional features and the morphometric characteristics of the teeth. The components of the dentofacial system as well as their adaptive and compensatory potential are subject to correlated variability; in other words, they are covariant. The length and diameter of the implants as well as their macro- and microrelief that remain unaltered (i.e. invariant) during the period of their functioning can be regarded as the governing parameters of consistence of the restored bone tissue-implant orthopedic constructions. The hypothesis of parallelism between the morphometric covariant teeth characteristics and the invariant design features of the dental implants as the ideological basis for the solution of the problem of their consistence with respect to the functional orientation in different parts of the dental arch needs to be more thoroughly substantiated. The authors of the present publication present the arguments in favour of the necessity of the in-depth investigations with a view to achieving this goal.
