Nuovo dispositivo per l’espansione rapida del palato in dentatura mista

Objective

To present a new device that allows palatal expansion with a main skeletal component and a reduced vestibular tipping of supporting teeth.

Methods

The sample consisted of a group of 100 children aged between 5 and 12. The new device “New REP” was cemented on second primary molars. The clinical protocol was 1/4 turn of screw three times a day for a maximum of 12 days.

Results

In this group the opening of palatal suture was obtained with high predictability after four days; the expansion was completed within 12 days and the initial occlusal problem was solved in all patients.

Conclusions

The “New REP” developed by the authors according to the biomechanical principles involved allows to open the palatal suture after four days in a highly predictable way and to solve dental basal discrepancies within 12 days using the second primary molars as anchorage teeth.
