Clinical Pearls for Post Disassembly and Retreat of Upper Anterior
Presentation Category
Endo
Introduction/Context/Diagnosis
This is a clinical case demonstrating the multiple steps involved in retreating an anterior tooth including the disassembly of a metal post as well as removal of gutta percha and placement of a fiber post after obturation.
Methods/Treatment Plan
#7 had to be retreated due to symptomatic apical periodontitis as well as the student provider planning to fabricate a new crown along with the other upper anteriors. Metal post was removed utilizing a combination of ultrasonics as well as the Ruddle post removal kit and Stieglitz forceps. Endo ice spray along with water spray was used at regular intervals to help ensure tooth does not overheat during post removal. After post removal, gutta percha was removed using Trushape rotary files followed by hand files. After obturation, new fiber post was placed and new buildup.
Results/Outcome
Utilizing the methods mentioned above, the tooth was successfully retreated and pt was able to return to student provider to continue with restorative aspect of treatment plan.
Significance/Conclusions
The risk of thermal injury during post removal can be a serious complication as mentioned in published case reports so utilizing methods to control the increase in temperature of the tooth when performing this procedure is important. Different techniques can be utilized to facilitate post removal depending on provider preference so some of the techniques are demonstrated in this presentation. There are also multiple methods to remove gutta percha so in this case, a technique to remove gutta percha efficiently with a special rotary file is demonstrated.
