From: patrick baltieri To: ROOTS Sent: Friday, February 29, 2008 2:00 AM Subject: [roots] Retreatment and fiber glass post After a long time without post, I`m sending a case done yesterdey. Description: Crown and metallic post removed with US Desobturation with US and final shape with NiTi Obturation with white MTA (due the large apical size) and Cavit was used to protect MTA Confection of the fiber glass post reinforced with resin Buildup with Z350 resin - Patrick BaltieriLovely control and case. can you explain how you add the resin onto the post inside the canal? Are you using a separating medium while initially doing this and then re cleaning prior to bonding? - Bill Thanks Bill. I will describe the procedure: 1 After the RCT the tooth was prepared with low speed burs (peeso) and cleaned with alcohol and water; 2 the bonding agent was applied (ClearFil SEBond was used), followed by a lubricant soluble in water 3 The fiber glass post was prepared with silane and bond and a portion of resin was applied into the post (like in the picture) 4 The post with resin was taken in the tooth in movements modeling the root canal. After, the post was removed and polymerized out of the tooth. 5 The tooth was again washed with water and dried with air and paper points 6 A dual cement was used to cemente de fiber glass post reinforced with resin and I hope that this description answer your question, This article describe a similar technique to reconstructing an endodontically treated tooth: Grandini S, Sapio S, Simonetti M. Use of anatomic post and core for reconstructing an endodontically treated tooth: a case report. J Adhes Dent. 2003 Fall;5(3):243-7. Patrick Baltieri Are you sure that Clearfill SE can set with activator of dual cure cement - Roman Bakowicz The ClearFil SEBond is photopolymerized by the time specified by the manufacturer (Kuraray), before lubrificate the canal. - Patrick Baltieri Patrick, Can you tell us the lubricant used, and if you are sure you get the same bond strength following it's usage? Do you re apply the SE bond following removal of the lubricant? - Bill Hey Patrick.....nicely done case. Wonderful documentation ( what are you using for photos) and great result. It looked very nice at the end. Thanks for sharing. - Glenn Thanks Glenn, I'm using a Canon A95 and the Carr II photo adapter. - Patrick Baltieri Hello! nice docum, thanks for shearing Why did you use Cavit for MTA "protection" - does it harden without moisture-inside the canal? Does composite bond to temporary filling material? - I don't belive it! - Veiko Vengerfeldt Thanks VeiKo, This treatment was done in a single session and to bonding the root canal, I needed isolate the MTA that wasn't set, so to do that I used a thin layer of cavit. The composite is a temporary restoration, the will be prepared to a crown - Patrick Baltieri Great case Patrick! - Carlos Murgel Thanks Murgel - Patrick
