The technique of bonding fragments when dental fractures occur is a routine procedure. The objective of this investigation is to demonstrate the retention of the fragments bonded using a compound material according to the Simonsen technique. The most noteworthy conclusion is that this type of restoration lasts less than two years when in the mouth. For this reason other therapeutic options with better future expectations should be introduced.
The objective of this study was to carry out a comparative evaluation of the bond strength to enamel of two present-day fissure sealants, Helioseal® and Concise®; good adhesion of the material to the tooth surface is one of the requisites for the success of this preventive technique. To this end, 16 caries-free human premolars extracted for orthodontic reasons were used. Proximal, mesial, and distal surfaces were treated and studied. Bond strength was evaluated by the application of compression forces (Instron®) at a velocity of 0.5 mm/mm. The overall results obtained do not show significant differences between the two materials.
Restoration of cleaved mandibular incisors with modified partial-coverage ceramics using the edge-up technique shows fracture resistance and severity of crown fracture following traumatism similar to intact teeth. In this way, this technique can be used successfully for the treatment of fractured anterior teeth.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
