Whilst an incomplete ferrule provided by 2 mm of labial and palatal dentine and 0.5 mm proximally provided significant resistance to fracture compared with the teeth without coronal dentine, the complete ferrule was significantly more resistant to tooth fracture. The clinical significance of this difference is not clear.

2011年11月15日 · A ferrule effect is defined as a “360° metal collar of the crown surrounding the parallel walls of the dentine extending coronal to the shoulder of the preparation. The result is an elevation in resistance form of the crown from the extension of dentinal tooth structure” .

Ferrule Effect: A Literature Review - Journal of Endodontics
2011年11月15日 · Preserving intact coronal and radicular tooth structure, especially maintaining cervical tissue to create a ferrule effect, is considered to be crucial for the optimal biomechanical behavior of restored teeth. The ferrule effect has been extensively studied and still remains controversial from many perspectives.
Ferrule Effect: A Literature Review - ScienceDirect
2012年1月1日 · Based on the evidence from in vitro and in vivo studies reviewed, the presence of ferrule has a positive effect on fracture resistance of endodontically treated teeth. More successful prognosis could be expected if healthy dentin extending 1.5 to 2 mm coronal to the margin of the crown is provided circumferentially.
The effects of ferrule configuration on the anti-fracture ability …
2015年1月1日 · Fracture failure tests indicated that the palatal ferrule significantly enhanced the fracture resistance of the post-restored teeth, regardless the height of the labial ferrule. The fractography investigation exhibited that the crack initiated at the palatal margin of the cement layer and propagated to the cervical region of the root.
demonstrates that a ferrule effect occurs owing to the artificial crown bracing against the dentine extending coronal to the crown margin. Overall, it can be concluded that a ferrule is desirable, but should not be provided at the expense of the
This article reviews the dentistry literature on the ferrule effect, and presents alternative defi nitions for terms such as ferrule, the ferrule effect, and the ferrule tooth structure. The article also explains how the use of a surgical
