Treating a tooth with a massive post space with an anatomical custom made post. Clinical case by Dr Peet van der Vyfer. A 14-year old patient was referred to the practice, complaining of discolouration and pain on tooth number 11. She gave a history of a previous root canal treatment on the specific tooth, but it never ‘settled’ and became asymptomatic. The clinical examination revealed discolouration of the crown of tooth number 11. A peri-apical radiograph revealed a poorly performed root canal treatment. On removal of the palatal restoration the unacceptable status of the previous attempt to clean and obturate the root was clearly obvious. |

The root was retreated, cleaned and shaped and complete obturation was achieved, as can be seen on the post-op radiograph. Note the difference in post space diameter between the pre-op and post-op radiographs. The diameter of the root canal was approximately 4 mm, meaning that a massive post would be indicated. It was decided to construct an anatomical direct fibre reinforced post and the everStick® Post system from Stick Tech Ltd. was chosen as the material for post construction as this flexible system enables the clinician to manufacture a direct fibre post according to the anatomy of a specific tooth. Two 1.5 and one 0.9 diameter posts were combined, forming a post roughly 3.9 mm in diameter. The uncured post was placed in the root and the coronal part was light-cured for 15 seconds. |

The partially cured post was then carefully removed and the apical part of the post was then cured for 30 seconds, ensuring a total curing time of 45 seconds. The cured post was then inserted and the fit was checked. It was removed from the root and treated with Stick® Resin in order to create the micro-cavities that optimized the bond between the everStick ® Fibre Post and etched radicular dentine. The root was etched, bonded and dual cure resin cement was placed in the post space. The post was cemented. After curing the excess post material and cement was removed. The clinical crown was then prepared to accept a jacket crown. |
