摘要

BackgroundThe aim of this retrospective study was to compare the esthetic, periodontal, and functional outcomes of orthodontic space closure versus implant substitution in patients with missing maxillary incisors 5?years after completion of treatment.MethodsThe study group consisted of ten patients treated with orthodontic space closure (six males, four females, mean age 19?±?2.1?years at the completion of treatment) and ten patients treated with implant insertion (five males, five females, mean age 20?±?1.4?years at the time of implant insertion). Tooth mobility, plaque index, probing depth, infraocclusion, open gingival embrasure (black triangle), and temporomandibular joint function were recorded at the 5.6?years follow-up. Self-perceived dental esthetic appearance was also evaluated through a visual analog scale (VAS) questionnaire. T-test was used to evaluate the data.ResultsAll patients were equally satisfied with the appearance of their teeth 5.6?±?0.4?years after the completion of treatment. No statistically significant differences were found in relation to the VAS scores of the subjects (P?
