Spontaneous space closure in patients treated with early extraction of the first permanent molar: a retrospective cohort study using radiographs

CONCLUSIONS: The success rate of spontaneous space closure was high (84.3%) and was higher in the maxilla (94.1%) than the mandible (74.1%). Age at time of extraction and dental developmental stage of the SPM were significant factors for successful spontaneous space closure in the maxilla and mandible, respectively.PMID:38381800 | PMC:PMC10893924 | DOI:10.2319/061923-423.1
