The ferrule is considered to be a key element in teeth preparation when restoring using a fiber post. It helps to resist occlusal forces, maintain cement tightness and minimize stress concentration on restoration using posts.

Influence of intraradicular post and crown ferrule on the fracture strength of endodontically treated teeth. The aim of this study was to investigate the fracture strength of endodontically treated teeth restored with different posts and variable ferrule heights. All teeth were restored with full metal crowns. The fracture strength was measured in a universal testing machine at 45o to the long axis of the tooth until failure. When the mean fracture strength values were compared CP0 group -

This study evaluated fracture resistance with regard to ferrule lengths and post reinforcement on endodontically treated mandibular premolars incorporating a prefabricated post and resin core. Prepared teeth were restored with metal crowns. A thermal cycling test was performed for 1, cycles. Loading was applied at an angle of degrees to the axis of the tooth using a universal testing machine with a crosshead speed of 2. The fracture load of F2 Fracture resistance of ETT depends on the length of the ferrule, as shown by the significantly increased fracture resistance in the 2 mm ferrule group F2 compared to the groups with shorter ferrule lengths F0, F1 and without post NP. Non-vital teeth are significantly different in physical and mechanical properties compared to vital teeth.

Больше всего похоже на требование выкупа. Слова Сьюзан прозвучали слабым, едва уловимым шепотом: - Это… Энсей Танкадо. Джабба повернулся и изумленно посмотрел на. - Танкадо. Сьюзан едва заметно кивнула: - Он требовал, чтобы мы сделали признание… о ТРАНСТЕКСТЕ… это стоило ему… - Признание? - растерянно прервал ее Бринкерхофф.  - Танкадо требует, чтобы мы признали существование ТРАНСТЕКСТА.

У тебя скверный вкус на ювелирные побрякушки. - Ты уверен, что его никто не купил. - Да вы все спятили. Это за четыреста-то баксов. Я сказал ей, что даю пятьдесят, но она хотела. Ей надо было выкупить билет на самолет - если найдется свободное место перед вылетом. Беккер почувствовал, как кровь отхлынула от его лица.

 - Цуккини. - Сквош, - чуть не застонал Беккер. Сьюзан сделала вид, что не поняла. - Это похоже на цуккини, - пояснил он, - только корт поменьше. Она ткнула его локтем в бок. Левый крайний Джорджтауна, подавая угловой, отправил мяч в аут, и трибуны негодующе загудели. Защитники поспешили на свою половину поля.

Impact of a Core Ferrule Design on Fracture Resistance of Teeth Restored with Cast Post and Core.

И в первую очередь я сожалею о Дэвиде Беккере. Простите. Я был ослеплен своими амбициями.

Стратмор медленно повернулся. Он являл собой печальное зрелище. - Это сделаю я, - сказал он, встал и, спотыкаясь, начал выбираться из-за стола.

Время идет, старик канадец может куда-нибудь исчезнуть. Вполне вероятно, он решит поскорее вернуться в Канаду. Или надумает продать кольцо. Беккер не мог ждать.
