Background: Early orthodontic treatment is important to guide dentitions during the development of a functional and morphological occlusion. Anterior dental crossbite and thumb sucking habits can be treated by interceptive orthodontic treatment modalities that are a method to restore a normal occlusion when a malocclusion has started to occur. Case Presentations: The cases shown are ranging from the age of 7-9 years presenting in mixed dentition development. This article presents six cases of anterior crossbite corrected by using removal acrylic appliances with Z spring and two cases of thumb sucking habits corrected by using palatal crib. Recall examination after 6 months displayed normal occlusal relationship without any relaps. Conclusion: Paediatric dentists have important role to diagnose malocclusions early. Early interceptive orthodontic treatment can potentially eliminate the need for future complicated and costly orthodontic treatment.
