Show more >Background: This study aimed to evaluate the impact of preventive infra-occluded primary teeth extraction in patients with dental agenesis on the success of pre-implantation and implantation treatment, and the preservation of alveolar ridge height. Material and methods: This retrospective analysis included 290 patients with dental agenesis treated at Lille University Hospital between December 2019 and January 2024, including 92 patients with infra-occluded primary teeth. Clinical and radiographic data were collected, and the implant outcomes were compared between those who underwent preventive versus delayed extractions. Results: Preventive extraction was associated with 100% preservation of alveolar ridge height and eliminated the need for vertical bone grafting. In contrast, 28% of patients with delayed extractions experienced vertical bone loss and implant infraposition despite complex grafting procedures. The second primary molars were the most frequently infra-occluded (66.5%), mostly at a moderate degree. The median ages at diagnosis, extraction, and implantation were 14, 17, and 18 years, respectively. Conclusions: Compared to delayed extraction, preventive extraction of infra-occluded teeth in agenesis cases facilitates better implant positioning and reduces the need for complex pre-implant surgeries. Timely intervention is key, particularly in the maxilla, to avoid vertical bone loss and implant complications.Show less >
