Double vs single primary tooth extraction in interceptive treatment of palatally displaced canines.

Objectives: To compare the impact of primary canine and primary first molar extractions with extractions of only the primary canine regarding correction of palatally displaced canines (PDCs).

Materials And Methods: Thirty-two children aged 9.5-13.

One year treatment effects of the eruption guidance appliance in 7- to 8-year-old children: a randomized clinical trial.

Background: The eruption guidance appliance (EGA) aims to correct sagittal and vertical occlusal relations concomitantly with alignment of the incisors. Few reports have been published on treatment effects with the EGA but no randomized studies have been available.

Objectives: The aim was to find out if 1 year active treatment time with EGA was sufficient for achieving normal occlusal relationships and dental alignment in 7- to 8-year-old children.
