An anxious 42 years old patient called me up to tell me that her crown fell off . Upon oral examination, her titanium (dowel) post in her tooth no. 11 broke in halves. I checked her periapical x-ray and saw nothing unusual around the root.
I used a 801 round bur to open the pathway to the canal and to have a better access to the broken titanium dowel. Then i used my ultrasonic instrument moving it inside in circumferential motion around the dowel pin to dislodge it from its cement. It took around 10 mins to remove it from the canal. I cleaned the canal with chlorhexidine 0.20% and dry the canal. I accidentally perforated the canal at the lingual side due to over instrumentation or a weakened wall . I used MTA denstply (white) on the perforated wall . I prefer MTA denstply here over MTA angelus eventhoigh it's in a syringe type. The strength and hardness of MTA denstply is superior to that of MTA angelus. I used angelus fiber post # 1 and cemented it with Rebilda voco up to the post build up. I used Duolink bisco to cement the Zircnia crown.
