Osteogenesis imperfecta (OI) is a genetic disorder that is usually caused by disturbed production of collagen type I. Depending on its severity in the patient, this disorder may create difficulties and challenges for the dental practitioner. The goal of this article is to provide guidelines based on scientific evidence found in the current literature for practitioners who are or will be involved in the care of these patients. A prudent approach is recommended, as individuals affected by OI present with specific dentoalveolar problems that may prove very difficult to address. Recommended treatments for damaged/decayed teeth in the primary dentition are full-coverage restorations, including stainless steel crowns or zirconia crowns. Full-coverage restorations are also recommended in the permanent dentition. Intracoronal restorations should be avoided, as they promote structural tooth loss. Simple extractions can also be performed, but not immediately before or after intravenous bisphosphonate infusions. Clear aligners are a promising option for orthodontic treatment. In severe OI types, such as III or IV, orthognathic surgery is discouraged, despite the significant skeletal dysplasia present. Given the great variations in the severity of OI and the limited quantity of information available, the best treatment option relies heavily on the practitioner's preliminary examination and judgment. A multidisciplinary team approach is encouraged and favored in more severe cases, in order to optimize diagnosis and treatment.
成骨不全症(OI)是一种遗传性疾病,通常由I型胶原蛋白生成紊乱引起。根据其在患者体内的严重程度,这种疾病可能给牙科医生带来困难和挑战。本文的目的是为目前或将来参与这些患者护理的医生提供基于当前文献中科学证据的指导方针。建议采用谨慎的方法,因为患有OI的个体存在特定的牙槽问题,可能很难解决。乳牙列中受损/龋坏牙齿的推荐治疗方法是全冠修复,包括不锈钢冠或氧化锆冠。恒牙列也推荐全冠修复。应避免采用冠内修复,因为它们会促进牙齿结构丧失。也可以进行简单拔牙,但不要在静脉注射双膦酸盐前后立即进行。透明矫治器是正畸治疗的一个有前景的选择。在严重的OI类型中,如III型或IV型,尽管存在明显的骨骼发育异常,但不建议进行正颌手术。鉴于OI严重程度差异很大且可用信息有限,最佳治疗方案在很大程度上依赖于医生的初步检查和判断。在更严重的病例中,鼓励并倾向于采用多学科团队方法,以优化诊断和治疗。
