Anterior Open Bite Treatment With Bonded Spurs Associated With Build-ups Versus Conventional Bonded Spurs

Brazil50 participantsStarted 2017-06-09

Plain-language summary

This study compares the dentoalveolar and skeletal effects of bonded spurs associated with build-ups versus conventional bonded spurs in the early treatment of anterior open bite patients. Half of participants will be treated with bonded spurs associated with build-ups, while the other half will be treated with conventional bonded spurs. The null hypothesis to be tested is that there are no differences for the dentoalveolar and skeletal effects between the two protocols.
