摘要
A crown-and-root reconstruction assembly made of composite materials with a modulus of elasticity varying along a gradient. The assembly comprises a physiological securing peg (4) and a crown reconstruction base (1) made of partially or completely light-conducting material. The connection between the crown reconstruction base (1) and the peg (4) is achieved by polymerising the material of the base under an isostatic charge. The forming process may be completed by manipulating the material with the fingers through a forming membrane (22) to prevent any gap developing at the interface (10) between the root (8) and the crown reconstruction base (1). A helical arrangement of the fibres (5) of the peg (4) ensures that the modulus of elasticity is close to that of the natural dentine, regardless of the angle of incidence at which the reconstruction is stressed.
