Occlusal Adjustment (Grinding) of Primary Dentition as Assisting Method During Crossbite Treatment in Primary and Early Mixed Dentition - Cases Report

A characteristic of all types crossbite malocclusions is that a part of the lower teeth cover the upper teeth and there is an asymmetry of dental arches. The midlines also may be noncoincident. Crossbite malocclusions need to be treated in most cases near the time of recognition because of unfavorable asymmetric patterns, anomalous development to the mandible and maxilla. It contributes to disorders in facial esthetic and it is harmful to the teeth or jaws, including the periodontium. In most cases, one can notice the constriction of the maxilla; therefore, the basic approach to the crossbite treatment is to expand of maxillary arch. This expansion of the maxillary arch during primary and early mixed dentition periods can be achieved by using removable appliances. The wearing time of these appliances, even in well-cooperating patients, is 12 to 14 hours per day. This is the reason why an occlusal adjustment of primary teeth is necessary, assisting method during crossbite treatment. It also helps to maintain the results of the treatment. The aim of the study is to present and to explain the principles of the occlusal adjustment of the primary teeth in the treatment of crossbite malocclusion based on selected cases.
