[Use of erbium laser for treatment of dental implant complications].

The paper presents the results of the use of Er:YAG laser for surgical treatment of 48 patients aged 25-73 years with early and late dental implant complications were presented. Among all lasers used in the field of dentistry, the Er:YAG laser seems to possess characteristics most suitable for oral treatment, due to its ability to ablate both soft and hard tissues as well as bacterial biofilms and calculus without causing major thermal damage to the adjacent tissue.

[Experimental study of dental implants with nanostructured non-resorbable coating integration into bone tissue].

In 2 dogs on both sides of mandible premolars were removed. In 3 months after dental alveolus healing intraosseous screwdriver dental implants (Konmet, Russia) were installed in the place of the removed teeth. Analogous operation was done on the contralateral side: the same type of implants were installed but with new nanostructured multifunctional biocompatible non-resorbable coating (MBNC) of the Ti-Ca-P-C-O-N composition.

[Critical bone defects elimination by bioengineering construction upon non-resorbable polymeric base with the use of autogenic multipotent stromal cells from adipose tissue].

On 8 rabbits with experimentally produced critical defects of calvarium plastics of the defects was performed by bioengineering constructions based upon porous polytetrafluoroethylene with multifunctional nanostructured non-resorbable cover Ti-C-Ca-P-O-N and autogenic stromal cells from adipose tissue (the main group -4 rabbits). In the reference group (4 rabbits) the defects were repaired by abiologic implants. At the terms of 3 and 6 months in the main group under implants the formation of the full value bone regenerate was seen in the region of calvarium defects.

[A comparative analysis of healing mandibular defects due to exposure to different plastic materials (experimental morphological study)].

Autogenous bone grafts are the most effective factor able to activate osteogenesis in bone defects, as shown by our experiments. Experimental biomaterials such as Bio-Oss and KP-3 have a high osteogenesis potential, too. However the callus initiated in jaw defects by those biomaterials underwent partial reduction during secondary rebuilding, thus becoming a less authentic bone formation.

[The evaluation of the efficacy of using different types of implants].

Published reports on the clinical efficacy and remote results of treatment by dental implants of different types are reviewed. The authors assessed the incidence and causes of complications of implantations on the basis of a long (up to 12 years) follow-up of 865 patients to whom 1155 grafts were implanted. Methods for treating and preventing complications are developed.
