How To Deal With A Metal Post Discolouration

a year ago

Case description

A 40-year-old male was referred to our clinic, with the complaint of a discolored anterior tooth. The main origin of the discoloration is an improper metal prefabricated post. So, we tried to remove that ugly post first of all. Then we will replace it with an FRC adhesive post. A diamond bur can help you to clean the post from composites But never approach the root canal with a bur! An ultrasonic tip is the best instrument to make the post loose and free from types of cement. A counterclockwise movement with an ultrasonic tip can make a miracle! Try it! Miracle happened! Halleluiah!! We made the cavity free from infected dentin and also cement and composites. The cavity should be ready for a new FRC post. Loosing the post with an ultrasonic device may Thake a while, but be patient! It's safe instead! cut the incisal edge about 2mm To provide a proper post space, making the canal free from cement and gutta-percha could be enough. Embrace your magical ultrasonic device again! she is useful to clean the root canal space! Try in your fiber post. a narrow one that is slightly fitted to the canal is a good choice. Make the canal dry with a paper cone. Apply your bonding agent. In such cases, I prefer to use a dual-cure universal bonding system. Soak the fiber post into a mixed dual-cure self-adhesive resin cement, and put it into the root canal. Remove excess cement, using a fine micro brush Fill the crown space with composite. Start a regular preparation for a multi-layer Zirconia jacket crown. Place a suitable sub-gingival cord. Make an impression or use your digital intraoral scanner. It is not a big deal! Of course, I love digital dentistry! so, scanner is my choice... I used to deliver a temporary crown to my patients 2 or 3 hours later. I love to do it using a 3D printer. You can do it in any way you like but it's better to deliver a temporary. A couple of weeks later, the zirconia crown is ready to deliver The crown was delivered with temporary cement for about 40 days. After that, the crown's cement will be replaced with a permanent one, such as a resin cement
