What is Ferrule Effect and what are the Types of Ferrules
2016年12月25日 · Ferrule Effect is defined as “a 360-degree metal collar of the crown surrounding the parallel walls of the dentine extending coronally to the shoulder of the preparation” by Sorensen & Engelman. As much as coronal tooth as possible should be preserved, and an abut-joint margin between the core and tooth be used, i.e. minimal taper.
Ferrule effect: a literature review - PubMed
Providing an adequate ferrule lowers the impact of the post and core system, luting agents, and the final restoration on tooth performance. In teeth with no coronal structure, in order to provide a ferrule, orthodontic extrusion should be considered rather than surgical crown lengthening.
An In Vitro Study on the Effects of Post-Core Design and Ferrule …
2015年2月15日 · With 2 mm ferrule, teeth restored with custom cast post-core had a significantly higher fracture resistance than teeth restored with custom cast post-core or prefabricated post and glass ionomer core without ferrule. Keywords: cast-posts, endodontically treated teeth, ferrule, fracture resistance, prefabricated posts.
Effect of the ferrule on fracture resistance of teeth restored with ...
The ferrule effect in root treated teeth requiring cast posts and cores has been shown to greatly improve fracture resistance. Studies have also shown that in the case of a cast post and core, the longer the ferrule, the greater the fracture resistance.

2019年3月4日 · Ferrules have been tested when they are part of the core and also when the ferrule is created by the overlying crown engaging tooth structure. Most of the data indicate that a ferrule created by the crown encompassing tooth structure is more effective than a ferrule that is part of the post and core Endodontics, Ingle

2020年4月22日 · This document discusses the ferrule effect in restoring endodontically treated teeth. It defines a ferrule as a band of metal encircling the coronal tooth structure that extends at least 1.5-2mm below the finish line. The presence of a ferrule helps resist fracture by reinforcing the tooth against lever forces and post insertion stresses.
