Анализ литературы позволяет заключить, что при конусности стенок зуба в 15 градусов ретенция коронок составляет 70 % [<xref ref-type="bibr" rid="cit2">2</xref>]. Целью работы явилась разработка усовершенствованного способа соосного одонтопрепарирования зубов. В данной статье приведено описание методики одонтопрепарирования зубов, являющихся опорой под несъемные ортопедические конструкции протяженного характера. Суть способа заключается в создании ложа на опорных зубах с помощью тонкого фиссурного бора. Процесс соосного препарирования опорных зубов в авторской методике состоит из нескольких этапов, что дает возможность осуществлять контроль за точностью препарирования и качественно снизить вероятность чрезмерного сошлифовывания тканей зуба.</p></abstract><trans-abstract xml:lang="en"><p>A common mistake of an orthopedic dentist when carrying out odontopreparation of teeth is nonobservance of the parameters of the permissible convergence of the axial walls of the teeth [<xref ref-type="bibr" rid="cit1">1</xref>]. Analysis of the literature allows us to conclude that with the taper of the tooth walls at 15 degrees, the retention of the crowns is 70 % [<xref ref-type="bibr" rid="cit2">2</xref>]. The aim of this work was the development of an improved method for coaxial odontopreparation of teeth. This article describes the method of odontopedication of teeth, which are a support for fixed orthopedic structures of an extended nature. The essence of the method is to create a bed on the abutment teeth using a thin fissure bur. The process of coaxial preparation of abutment teeth in the author's technique consists of several stages, which makes it possible to control the preparation accuracy and qualitatively reduce the likelihood of excessive grinding of tooth tissues.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>одонтопрепарирование зубов</kwd><kwd>конвергенция</kwd><kwd>ретенционное препарирование</kwd></kwd-group><kwd-group xml:lang="en"><kwd>odontopreparation of teeth</kwd><kwd>convergence</kwd><kwd>retention preparation</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Seymour KG, Samarawickrama DY, Lynch EJ.
