RESUMEN
INTRODUCTION: The objectives were to describe the peri-operative management of people with inherited bleeding disorders in oral surgery and to investigate the association between type of surgery and risk of developing bleeding complications. MATERIALS AND METHODS: This retrospective observational study included patients with haemophilia A or B, von Willebrand disease, Glanzmann thrombasthenia or isolated coagulation factor deficiency such as afibrinogenemia who underwent osseous (third molar extraction, ortho-surgical traction, dental implant placement) or nonosseous oral surgery between 2014 and 2021 at Bordeaux University Hospital (France). Patients and oral surgery characteristics were retrieved from medical records. Odds ratio (OR) and 95% confidence interval (CI) were estimated using logistic regression. RESULTS: Of the 83 patients included, general anaesthesia was performed in 16%. Twelve had a bleeding complication (14.5%) including six after osseous surgery. The most serious complication was the appearance of anti-FVIII inhibitor in a patient with moderate haemophilia A. All bleeding complications were managed by a local treatment and factor injections where indicated. No association was observed between type of surgery (osseous vs. nonosseous) and risk of bleeding complications after controlling for sex, age, disease type and severity, multiple extractions, type of anaesthesia and use of fibrin glue (OR: 3.21, 95% CI: .69-14.88). CONCLUSION: In this study, we have observed that bleeding complications after oral surgery in people with inherited bleeding disorders were moderately frequent and easily managed. However, in this study, we observed a serious complication highlighting the necessity of a thorough benefit-risk balance evaluation during the preoperative planning of the surgical and medical protocol.

Pre-implant bone surgery in oral surgery allows to reconstruct maxillary atrophies related to traumatic, infectious or tumoral processes. In this context, the ideal biomaterial remains autogenous bone, but biomaterials (of natural or synthetic origin) allow to limit the morbidity linked to bone harvesting, and to simplify these surgical procedures. In this article, we illustrate how 3D printing technologies can be used as an adjuvant to treat bone defects of complex shape or to create anatomical models used to plan interventions. Finally, some perspectives brought by tissue engineering and bioprinting (creation of complex in vitro models) are presented.
Title: Impression 3D et bioimpression pour la régénération osseuse en chirurgie orale. Abstract: La chirurgie osseuse pré-implantaire en chirurgie orale permet de reconstruire les atrophies des maxillaires en rapport avec des processus traumatiques, infectieux ou tumoraux. Dans ce contexte, le biomatériau idéal reste l'os autogène mais les biomatériaux (d'origine naturelle ou synthétique) permettent de limiter la morbidité liée aux prélèvements osseux et de simplifier ces interventions chirurgicales. Dans cet article, nous illustrons l'apport récent de l'impression 3D dans ce contexte pour traiter des défauts osseux de forme complexe ou pour créer des modèles anatomiques servant à planifier les interventions. Enfin, les perspectives apportées par l'ingénierie tissulaire et la bioimpression (création de modèles in vitro complexes) sont détaillées.
