Distal shoe due to premature loss of eruptive guidance. Presentation of a clinical case.

Abstract

Summary. The occlusion is established because of the interaction of genetic and environmental factors. Primary dentition is of paramount importance for the maintenance of occlusion, aesthetics, phonetics, and psycho-emotional well-being of the child. The migration of the first permanent molar in the absence of the second primary molar causes a localized loss of space. The space maintainer called the distal shoe, turns out to be beneficial for restoring the eruption of the non-erupted permanent first molar. Objective. Restore the eruptive guide of the first permanent molar due to the premature loss of the primary molars, as well as the function and the masticatory stimulus. Clinical case. A 5.4-year-old male with premature loss of a right primario lower molar by intra-hospital approach infectious process 6 months ago. Prior to the oral rehabilitation of the patient, a fixed apparatus of the distal shoe type was performed with an anchor in a chrome steel crown modified with acrylic molars in the edentulous area, an incision was made in the mucosa for the contact of the shoe with the mesial face of the non-erupted permanent first molar. Restoring the eruptive guide of the permanent first molar, masticatory function and the vertical dentoalveolar dimension of the posterior sector. Conclusions. The conventional designs of space maintainers are not a rule, they can be modified to satisfy the patient's attention needs, establishing a bond between parents and the patient for radiographic control and preventive follow-up of eruption and oral health monitoring.
