ABSTRACT
INTRODUCTION: To assess the feasibility of a realistic model for learning oral flaps using 3D printing technology. MATERIALS AND METHODS: A mould was designed to reproduce the mandibular gingival mucosa, and a mandibular model was created using a three-dimensional printer for training undergraduate students to perform gingival flaps. After a short interview about its use, the participants were asked to use the simulator and provide feedback using a 5-point Likert questionnaire. RESULTS: The 3D-printed oral surgery flap training model was practical and inexpensive. The model was very realistic, educational and useful for hands-on training. CONCLUSIONS: 3D printing technology offers new possibilities for training in dental treatments that are currently difficult to replicate. The use of this simulator for oral flap surgery was well-received and considered promising by the participants.

Dentigerous cysts are the second most common odontogenic lesion, after radicular cysts. Dentigerous cysts mainly affect individuals in their second to fourth decades of life, with a slight male predominance. Because diagnosis is often late, surgical procedures like enucleation and removal of the impacted tooth misplaced are often necessary. However, if a dentigerous cyst is detected early in a child with delayed tooth eruption, the treatment goal is to preserve and properly position the permanent tooth within the arch. In such cases, conservative approaches like cyst decompression may be considered appropriate. We present a case of a dentigerous cyst in a 10-year-old child with delayed eruption of teeth 22 and 23. The condition was managed using decompression alone and orthosurgical traction, which facilitated the proper placement of the impacted teeth within the arch. This article emphasizes the significance of a multidisciplinary approach involving surgical and orthodontic management for dentigerous cysts in children, along with the importance of patient compliance with the treatment plan.
ABSTRACT
INTRODUCTION: the aim of this study was to report and assess the management and implant rehabilitation of oligodontia patients since its recognition in 2012 by french authorities in the nomenclature. MATERIAL AND METHODS: we conducted a retrospective study in the Maxillofacial Surgery and Stomatology Department of the Lille University Hospital between January 2012 and May 2022. Patients had to present an oligodontia recognized under the ALD31 in adulthood, and to have benefited from a pre-implant/implant surgical treatment in the unit. RESULTS: a total of 106 patients were included in the study. The mean number of agenesis was 12 per patient. The most missing teeth are the ones at the end of the series. After a pre-implant surgery phase including orthognathic surgery and/or bone grafting, 97 patients benefited from implant placements. The mean age for this phase was 19.38. A total of 688 implants were placed. The median number of implants placed was 6 per patient and 5 patients presented implant failures after or during the osseointegration phase (16 implants lost). The implant success rate was 97.6%. 78 patients benefited from rehabilitations by fixed implant-supported prostheses and 3 by implant-supported mandibular removable prostheses. DISCUSSION: The described care pathway seems to us adapted to the patients followed in our department, with good functional and esthetic results. It would be necessary to evaluate on a national scale to adapt the management process.
