Summary

The study evaluates the effects of palatal crib versus bonded spurs in the early treatment of anterior open bite caused by non-nutritive sucking habits.

Detailed description

Habit is an unintentionally performed repeated activity. Development of habit is considered a part of the natural progression of maturation in children between infancy and three years of age, after this period, it is assumed to be unnatural. The most familiar and earliest noted habit is thumb sucking. It develops during infancy as a rooting reflex, after it ceases around three years of age . Thumb sucking is defined as the placement of the thumb or one or more fingers in different depths into the mouth ). It emerges in two forms: nutritive and non-nutritive, where the first gives nourishment and the second implements a sense of security and amenity. It is common in children and is reported to be harmless for up to five years of age . There is an association between the habit of thumb sucking and the development of skeletal open-bite among children. Anterior open bites (AOBs) are defined as an occlusion in which the lower incisors are not overlapped in the vertical plane by the upper incisors and do not occlude with them when the posterior teeth are in maximum intercuspation . Anterior open bite due to thumb sucking, and a secondary tongue thrust exaggerates the condition . If identified early, this can be avoided and appropriate treatment is delivered. Approaches for habit intervention include counseling, positive reinforcement, a calendar with rewards, an adhesive bandage, bitter nail polish, long sleeves, and appliance therapy. It is recommended to start with the least invasive methods before using habit-breaking appliances. Habit-breaking appliances are either fixed or removable. Fixed appliance therapy may be considered after the age of 4 years. Appliances consisting of cribs in the anterior region are very efficient as reminders and physical restrainers . The palatal crib works as an obstacle in non-nutritive sucking and maintains the tongue in a more retruded position, halting its interposition between the incisors. Spur appliances change tongue action, close the open bite, and boost treatment stability, as it induces a permanent modification of the tongue's anterior rest posture by altering orofacial function, resulting in a change in form. Finally, the spur adjusts the sensory input to the brain. This proprioceptive change leads to an altered motor response, resulting in a new normal tongue rest posture (change in function) that allows the incisors to erupt.
