ABSTRACT Objectives To identify changes in orthodontic management strategies patients with hypodontia seen 2000, 2010, and 2017/2018 (during a 1-year period). Materials Methods An assessment of the panoramic radiographs 3701 from Western Australian private practice identified 276 individuals demonstrating hypodontia. The location missing teeth, age, sex, type malocclusion, (space closure or opening) for each patient were noted. Results Most involved agenesis three fewer teeth (90%). Maxillary lateral incisors mandibular second premolars most commonly teeth. Female preponderance was When considering treatment, odds ratio space opening prosthetic replacement 2000 3.266 (P value = 7e-04; 95% confidence interval [CI], 1.464–4.633) compared 2010 1.632 CI, 0.811–2.434) 2017/2018. For bilateral absence maxillary incisors, 3.185 0.0215; 1.182–9.243) counterparts unilateral agenesis. None factors investigated significantly associated types treatment planned/provided premolars. Conclusions A trend away toward observed to This may reflect change attitude options and/or greater optimism biomechanical since implementation temporary anchorage devices assist closure.
