Maxillary deficiency and/or openbite malocclusion are quite common in orthodontics clinics. The etiologies of these anomalies include genetic traits or later acquired features such as oral respiration, infant swallowing, and tongue repatriation. Nowadays, mini screws for anchorage are preferred because patient cooperation is not necessary and easy to apply. A 16-year-old female patient with circular openbite who was found to have a maxillary stenosis and at the same time an anterior region of 10 mm was referred to the NEU Dentistry Department's Orthodontics Department. After the radiographic evaluation of the patient, it has been found that she has completed her growth. Treatment of the case was planned with the use of Rapid Maxillary Expander (RME) appliance and mini screw application. One mini screw is inserted into each of the right and left buccal regions. Closed coil springs were added to the RME appliance with additional buccal bendings. Closed coil springs in the right and left buccal region of the patient, who had been exposed to expansion for 5 weeks, were activated so as to apply intrusive force of 200 gr and connected to the mini screws. The amount of force was checked every month and at the end of 8 months the appliance was abandoned. With the treatment, the amount of openbite decreased from 10 mm to 1 mm, intrusion in maxillary molars and counterclockwise rotation in the mandibula were observed. For the cases rejecting orthognatic treatment; it is observed that satisfactory results can be obtained by giving chance to more conservative treatment methods which are easy for patients and doctors.
