3D-Printed versus Conventional Palatal Cribs for Tongue Thrust in Children

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

In this randomized controlled trial, 30 children aged 7–10 with tongue thrusting and a Class I bite are assigned to either a 3D-printed cobalt-chromium palatal crib or a conventional soldered stainless steel crib. Over six months, researchers measure dental changes with 3D models, appliance durability, gum and plaque health, and how comfortable the devices feel to the patient. Outcomes focus on dentoalveolar dimensions, appliance integrity, oral health indices, and patient acceptance. The trial is conducted at the Faculty of Dentistry, Tanta University, with random allocation and standardized follow-up.
