Abstract
This case report illustrates the long-term changes of an adult Class II malocclusion treated with premolar extraction and a single-implant restoration replacing an ankylosed upper central incisor. A 20-year-old female showing Class II malocclusion with maxillary protrusion and ankylosed upper central incisor due to previous trauma visited the clinic. To improve the occlusion, first premolars of the maxillary and mandibular arch were extracted followed by comprehensive orthodontic treatment. After orthodontic treatment, the ankylosed upper incisor was extracted and replaced with a dental implant. Overall, the occlusion was stably maintained during the 10 years of retention. Interestingly, the interdental papilla between the implant and the adjacent central incisor and the gingival soft tissue continued to remodel over time improving the micro-esthetics of the maxillary incisor region as well as the occlusion.
