Objective: Premature loss of posterior deciduous teeth is very common and interferes with the chronology and sequence of dental eruption, leading to malocclusions like the deficiency of arch space for correct dental alignment and interference with tooth eruption chronology. Thus, the dentist should be aware of all factors involved in the dental arch space, and the methods to recuperate these spaces if they were lost early, and achieve success in treatments. Objective: The present study showed a clinical approach with the use of a removable appliance with expander screw and a bite plate to treat a case of early loss of mandibular deciduous molars, with severe loss of space in the dental arch. Conclusions: This approach was effective for the recuperation of space lost in the dental arch, referring to the second premolar, being a simple and satisfactory technique.
