At present, the osteoplastic materials application field is quite the different and diverse one - from the bone defects filling just after the teeth extraction before the implantation, up to the osteo - replacing operations, for the purpose of the bone tissue regeneration accelerating. However, we have not yet met the necessary information on the alveolar process augmentation at the stage of the orthodontic treatment with the following permanent teeth removal in the modern literature.

In this connection, we have offered to be formed the postextractional spaces, simultaneously, with the tooth extraction by the orthodontic indications. So, to do this, we have performed the alveolus gentle curettage after the tooth removal, then we have filled the alveolus with the dense biomaterial (e.g. the osteomatrix, the biomatrix, the bioimplant, the kola-
pol - kp, the blood plasma), we have put in the stitches and have inserted the sutures upon the mucous membrane and the periosteum. We have distributed the biomaterial by the vestibular, the lingual or the palatal bone surface for the further alveolar arch widening, the bone contour correction, besides the dense biomaterial filling, then we closed and repaired the wound, and, after that, we have mobilized the mucous membrane. Moreover, we have created the orthodontic load a month (e.g. 30 days and nights) just after the augmentation conducting.

Thus, the patients had been divided into the 2 groups: the patients, for whom the postextractional spaces have been formed just after the tooth extraction by the different and the various methods, entered into the first (e.g. or the basic) group. So, the patients of the second group refused from the offered surgical correction methods, and then, the orthodontic treatment by the generally accepted methods has been conducted for them.

So, the bone tissue loss has been evaluated, as in the vertical, well as in the vestibular - lingual directions.

So, the obtained research results had been shown, that the postextractional spaces alveolar crest defect size in the first group was made up 0,19 ± 0,11 mm in the vertical direction; it was made up 0,9 ± 0,12 mm in the vestibular one, and it was made up 0,78 ± 0,11 mm in the lingual one. At the time, as all these indices had been made up in the comparison group: 2,95 ± 0,5; 1,9 ± 0,23 and 2,05 ± 0,26 mm, correspondingly. Thus, the defect size at the patients of the basis group was quite less, than in the comparison group.
