ABSTRACT:
The restoration of a diseased or damaged tooth is carried out by decoronating the tooth leaving the root canal exposed. Then the canal is reamed, cleaned, irrigated, and obturated. It is then rereamed to a predetermined size leaving the apical portions filled with obturatory material and treated with a dentinal bonding agent. A perforated, hollow tubular outer post is inserted into the prepared canal and a paste or liquid composite is injected into the canal through the outer post. A serrated rod-like inner post is inserted into the outer post, and distributes the composite within the canal, forcing excess into the coronal area. After insertion, a spade-shaped top end of the inner post projects from the canal. A prep former is filled with a dental composite and is emplaced on the root over the inner rod upper end. This hardens to become a crown core onto which a prosthetic crown is affixed. This technique permits one-visit treatment, precludes abnormal internal stresses to the root structure, and can be carried out on unusual, difficult canal roots using standard dental equipment.
