[Study of stomatological status in patients of dental implantological clinic according to the data of orthopantomography and computer tomography].

During examination before dental implantation with the use of orthopantomography (OPTG) and computer tomography (CT) stomatological status was studied in 242 patients of the Clinical stomatologic centre of FMBA, Russia. Indices of frequency and intensity of dental caries and periodontal disease were determined, as well as frequency of maxillary sinuses pathology, evaluation of the preliminary endodontic treatment quality was given, morphometric data governing frequency of indications to bone-plastic operations were presented. The advantages of CT over OPTG were shown during patients examination before dental implantations were maid.

[Deflected mode of cortical bone tissue in 3-dimentional math mandible model of in state of intraosseous implant loading in lateral part of dentition].

Math modeling of mandible was executed in the presence of intraosseous implant in lateral part of dentition. Deflected mode of cortical bone tissue around implant, in alveolus and other mandible parts were studied in case of vertical load of 250 N upon implant. Values of tension in cortical bone tissue in the region of incisors, canines, molars and jaw body spreading in mediodistal, buccolingual and vertical directions were received.
