Comparison of Stress Distribution in a Maxillary Central Incisor Restored with Two Prefabricated Post Systems with and without Ferrule Using Finite Element Method [PDF]

Journal of Clinical and Diagnostic Research, 2016
Introduction: When restoring an endodontically treated tooth with deficient coronal tooth structure, posts can be used to strengthen the tooth. Recently prefabricated posts are widely used as they exclude the need for complex laboratory procedures ...

Solitary median maxillary central incisor: A case report of a rare dental anomaly

Journal of Pharmacy and Bioallied Sciences, 2015
The solitary median maxillary central incisor (SMMCI) syndrome is a rare dental anomaly and has an incidence of 1:50,000 live births. In SMMCI, there is only one central incisor present, and it develops exactly at the midline.

Effect of three different attachment designs in the extrusive forces generated by thermoplastic aligners in the maxillary central incisor

Dental Press Journal of Orthodontics, 2020
Introduction: Orthodontic aligners use have increased in dentistry. The resolution of complex movements such as extrusion demands the use of attachments to reach the aimed force, but just a few studies have been developed to evaluate the biomechanical ...
