[Prerequisites for improving the method of guided bone regeneration].

The purpose of this article was to discuss the need for the introduction of the concepts of 'vicryl situational frame' and 'the plastic substrate', in which the first one updates the shape-generating aspect of reconstruction, the second one - its volume-generating aspect. The latter is described as a new surgical technique. The great importance of a new level of methodological and methodical support the method of GBR, which determines the high clinical and prognostic indicators of effectiveness was concluded.

[Guidelines for staged maxilla bone and soft tissue augmentation].

The paper contains guidelines for implant placement in case of bone and soft tissue maxilla defects. The approach is based on the possibility of staged realization of tissue regenerative potential. Using conception of "osseointegration" and "reparative regeneration" the following terms were defined: distant reparative osteogenesis, bone regenerate, structure components of bone regenerate, ortho- and heterotopic osteogenesis, regenerative macro- and microenvironment.
