Root preservation of permanent teeth for the purpose prevention of atrophy of the alveolar process
Currently, broken roots of teeth are often removed (due to trauma). And often the installation of intraosseous implants of optimal length and diameter is impossible due to anatomical, physiological and functional changes in alveolar bone atrophy, depending on the cause and prescription of tooth loss, which is significant limits the use of dental implantation (Ivanov A.S. 2011, Ivanov S.Yu. et al. 2004; Kulakov A.A. et al. 2006; Robustova T.G. 2003, Fedorov V.E. et al. 2010; Fedorov V. E. et al. 2011). The alveolar process, deprived of its main supporting function, always undergoes atrophy after tooth extraction (Hing K.A.2004; Hollinger J.O.2005). Loss of teeth is almost always accompanied by resorption (atrophy) of the bone tissue of the jaws, in particular, the lower jaw. As a result of atrophy, both the height of the alveolar part of the lower jaw (AMN) and its width decrease, which complicates the standard methods of dental implantation (Matveeva A.I. 1993; Olesova V.N. 1993, 1999; Surov O.N. 1993; Markov B.P. 2000; Weiss Ch.M. 1992; Linkow L.I. 1993; Mish C.E. 1993; Cranin A.N.1993; Spikearman H. 1995;.)
