悬臂式固定局部义齿(CFPD)作为替代后部缺失牙齿的有效方法而获得了认可。本病例报告的目的是证明这种类型的恢复可以在一次预约中进行。一名39岁的患者到牙科部门就诊;她显示两个第一上颌前磨牙的发育不全,远端间隙完全闭合,最近失去了2个上颌前磨牙。此病例报告涉及更换左上第二前磨牙。患者在第一磨牙的“高嵌体样”保持器上进行了近端CFPD治疗,并用悬臂梁代替了缺失的前磨牙。连接横截面的尺寸尽可能最大化(>20mm2)。修复体是使用椅子旁的CAD-CAM从铣削增强的玻璃陶瓷块(EmaxCAD,IvoclarVivadent)。假体的美学和功能整合是成功的。在11个月时对患者进行了检查以进行随访。在这个早期阶段,观察到满意的牙齿卫生,与光滑的假肢配合有关,没有牙周炎症,正常探测,牙齿没有异常移动。
The cantilevered fixed partial denture (CFPD) is gaining recognition as a sound method of replacing missing teeth in the posterior sector. The purpose of this
case report is to demonstrate that this type of restoration can be performed in a single appointment. A 39-year-old patient presented herself to the dental department; she showed agenesis of the two first maxillary premolars with a totally closed mesio-distal gap and a recent loss of the 2 s maxillary premolars. This
case report concerns the replacement of the upper left second premolar. The patient was treated with a mesial CFPD resting on an \"onlay-like\" retainer on the first molar and replacing the missing premolar with a cantilevered pontic. The dimensions of the connection\'s cross-section were maximized as much as possible (>20 mm2). The restoration was designed and produced using chairside CAD-CAM from a milled-reinforced glass-ceramic block (Emax CAD, Ivoclar Vivadent). The aesthetic and functional integration of the prosthesis was successful. The patient was examined at 11 months for a follow-up. At this early stage, satisfactory dental hygiene was observed, associated with a smooth prosthetic fit, no periodontal inflammation, normal probing, and no abnormal dental mobility.
