Abstrakt: Purpose: Midline diastema due to simultaneous interplay of mesiodens and thumb-sucking habit is a very uncommon situation and can represent negative impact in the esthetics and functional standpoint. The purpose of this article is to describe a 9 year-old case with a 9-mm midline diastema and an anterior open bite treated with an interceptive orthodontic approach. Case Description: After orthodontic diagnosis, treatment undertaken was the surgical removal of the mesiodens and the use of a palatal crib therapy in order to discontinue the thumb habit. Then, orthodontic brackets were bonded on upper central incisors and the diastema closed allowing the spontaneous irruption of the upper laterals incisors. When acceptable levels of overbite and overjet were achieved and the habit controlled orthodontic treatment was discontinued. Conclusions: It is important to remember that to assure good results in managing pathological midline diastemas the diagnosis and treatment should be performed as early as possible.
