Abstract

Abstract: Tooth eruption occurs when the tooth moves from its non-functional position to occlusion in the oral cavity. This process depends on several factors to occur without alterations. Ectopic eruption of the first permanent molars is common in the mixed dentition and requires immediate treatment by pediatric dentistry. Its main cause is a hypoplastic maxilla, causing atypical resorption faster than normal, hastening the exfoliation of the primary molars and leading to a loss of space in the upper arch and crowding.Objective: To present the integral treatment in pediatric dentistry to correct maxillary hypoplasia. Case report: An asymptomatic 6-year-old female patient attended dental consultation for the first time in 2019.

Clinical examination and diagnostic aids showed a class III skeletal relationship due to hypoplastic maxilla with moderate dentoalveolar discrepancy and ectopic eruption of the first upper permanent molars. Maxillary expansion treatment was started with Hyrax and facial mask. Premature loss of 55 and 65 occurred, so the permanent molars were mesialized. In 2020 a bone-supported pendulum was installed. At one year follow-up, correction of the eruption path of the first permanent molars is observed. Conclusion: Treatment for ectopic eruption of the upper permanent first molars should be planned in a comprehensive manner, achieving objectives in each treatment period to avoid complications in the future.
