Root canal treated teeth are structurally compromised as a result of loss of tooth structure due to caries, iatrogenic cavity preparation, and dehydration. Given that a direct relationship exists between the amount of remaining tooth structure and the ability to resist occlusal forces, it is vital to provide a restoration allowing cuspal coverage as soon as possible following completion of the root canal treatment. A decision to provide a full crown or an onlay depends on the remaining tooth structure, if the cuspal width to length ratio is 1:2 or more, an onlay can be placed. When the ratio is <1:2, a full crown has to be planned. In single rooted teeth requiring postendodontic restoration cast post and core or a prefabricated post can provide resistance to fracture with comparable results. However in case of premolars, where only cuspal coverage is being practiced, it would require cervical reinforcement in addition, to counter the horizontal force acting at the cervical region. A new onlay design with a post extending into the radicular portion of the premolar providing the required reinforcement in a conservative manner and protecting it against both vertical and horizontal forces is proposed herewith called as SHARONLAY I.P. no 1956475. |
