Retention strength of ball-attachment titanium post for removable partial denture or overdenture
Aim: To evaluate the retention of an endodontic titanium post with a spherical head for removable partial denture or overdenture attachment according to surface treatment type. Methods: Sixty healthy single-rooted teeth, sectioned at the enamel/cementum junction, were treated endodontically and steadily fixed in the embedding acrylic resin. The titanium posts were subdivided into four groups: control, no surface treatment (Ctrl); posts with macro-retentive grooves (MR); air abrasion of the post surface (AB); and posts with macro-retentive grooves and air abrasion of the post surface (MR+AB). The posts were luted in the root canal using self-adhesive dual resin cement. Pull-out testing was p…
Raccomandazioni cliniche in odontostomatologia
L’Organizzazione Mondiale della Sanità considera la salute orale come parte integrante, non solo dello stato di salute generale, ma anche della qualità della vita di ciascun individuo. In tale ottica, in accordo e con il sostegno del mondo professionale e della comunità scientifica di questo settore, le raccomandazioni cliniche in odontostomatologia contenute nel presente volume forniscono indicazioni e definiscono standard di intervento per la prevenzione e la cura delle più comuni patologie del cavo orale nonché per l’identificazione di percorsi terapeutici appropriati a supporto degli operatori pubblici e privati. Esse costituiscono, inoltre, uno strumento utile per mantenere alto il liv…
Fiber Post Removal: Comparative Study Using a New Post Concept
Objectives: To evaluate the time required to remove endodontic posts made of quartz and glass fibers, and compare them to a new glass fiber post designed for easy removal on the basis of efficiency and tooth damages. Methods: 40 human single-rooted teeth were treated endodontically and randomly assigned to four fiber posts groups: 1) was restored with Premier#90 (Innotech); 2) with DT#2 Lightpost (Dentsply); 3) with Unicore#3 (Ultradent); 4) with a special, soft-cored “S” glass fiber post ER-Prosthetic#3 (Overfibers). An impression of the canal was taken prior post cementation. The posts were luted with Panavia F and adhesive (Kuraray). All the specimens were mounted in a dental simulation …
