Root canal therapy is not always successful and an increasing number of patients are requesting retreatment to address intraradicular infection. The armamentarium available to assist the dentist, some of which is described in this article, has never been greater.
Indirect restorations can provide a conservative, functional and aesthetic method for managing a patient's dentition. These restorations, however, are only as good as the environment in which they are placed. Many restorations, though technically satisfactory, may fail because assessment and subsequent treatment planning has been unsatisfactory. This article presents a philosophy of case selection mindful of factors related to the patient, operator and oral environment. The wrong treatment, however skilfully executed, may invite failure.
Modern post preparation techniques reflect a change from what was once considered a prosthodontic procedure to one which marries endodontic principles with sound understanding of mechanical objectives. This article presents a rationale for techniques in materials selection and post-space preparation. A review of literature is presented and practical clinical guidelines are suggested when post placement is considered the treatment of choice.
