H. Moscovich et Nhj. Creugers, THE NOVEL USE OF EXTRACTED TEETH AS A DENTAL RESTORATIVE MATERIAL - THE NATURAL INLAY, Journal of dentistry, 26(1), 1998, pp. 21-24
Objective: This preliminary study aimed to find out whether it is poss
ible to produce a well fitting Class II inlay from an extracted tooth
using a copy-milling technique. Methods: Two pairs of matching sound e
xtracted permanent molar teeth were used. The molars were matched for
mesio-distal size of the tooth crown and the convexity of the approxim
al surfaces. One tooth of each pair was assigned to be the 'donor' too
th, the other tooth being the 'host'. MO inlay preparations were made
in the host teeth. These were restored with the milled 'Natural Inlays
' produced from the donor teeth using the CELAY system. The restored h
ost teeth were sliced and examined using light-microscopy. Results: Th
e specimens showed the desired location of enamel and dentine, and a c
linically acceptable fit. Conclusion: This study has shown that by usi
ng the CELAY milling machine it is possible to 'recycle' extracted tee
th for the production of dental restorations. (C) 1997 Elsevier Scienc
