Definitions

  • these various metallic posts have the disadvantage of determining a strong concentration of stress at the level of the tooth root, appreciably increasing the risk of radicular fractures and consequent loss of the tooth.
  • Recently standard size posts have been proposed, i.e. based on carbon fiber and created industrially, with a module of elasticity similar to that of the radicular dentine.
  • due to their black color they are quite certainly anti-esthetic in the event the subsequent prosthetic reconstruction is to be realized with materials lacking metal.
  • the materials used for the realization of posts and cores are based on fibers bound in a resinous matrix already directly assembled by the constructor to make up pre-shaped structures to be adapted individually and therefore cured, or separated from resinous and glass fiber materials which are then combined in order to realize the material to be shaped (with the techniques described below) for the creation of individual posts and cores.
  • the constructive technique - similar in the basic principles - presents slight differences, which will be described later on, depending on whether one or the other of the two basic materials are used.
  • the diameter of the canal lumen is preferably at least 1.2 cm.
  • Collecting and applying material An equal length is applied, cutting away the excess with suitable clippers at the maximum length of the post and core to be realized.
  • the material is manipulated and applied with instruments for composite materials, inserted in the hollow left by the replica of the first silicone and subsequently adapted.
  • the core is particularly voluminous, (e.g. premolars or molars) it will be necessary to apply more material in the core area.
  • Repositioning of the transparent silicone above the first silicone mould exercising a minimal pressure for the purpose of producing an adaptation of the resinous material and checking that it is moderately in excess. Curing by light and pressure depending on the characteristics of the material.
  • the core is not completely made of fiber-reinforced material in the first phase but only a cylindrical lengthening is made, of a suitable height and diameter corresponding to the endocanal diameter of the post.
  • the core will subsequently be constructed by stratifying a composite material with individual esthetic characteristics.
  • the two half-moulds are executed but, in this case, using a non-elastic material, e.g. stone. Combine fibers and resinous matrix, placing it into the space left free by the replica in the mould and exercising a certain pressure. Curing follows, according to the characteristics of the material. Finishing is carried out by the procedure described previously. Any modifications of the core in shape or color may be made later with composite material of a suitable color. This type of material can be worked directly on the model without executing the replica and the moulds. In this case the material, appropriately prepared, is applied directly into the canal lumen and the reconstruction of the core follows. The final step is polymerization of the entire unit.

  • Combine fibers and resinous matrix placing it into the space left free by the replica in the mould and exercising a certain pressure. Curing follows, according to the characteristics of the material. Finishing is carried out by the procedure described previously.
