A long-term denture wearer exhibited advanced alveolar bone loss, resulting in an atrophic mandible. Symphyseal bone height was 10 mm. The inferior alveolar nerve and mental foramen were close to the crest of the mandible. The symphyseal region was available for endosteal implant placement. Patient was an 83-year-old white male who was medically compromised. Anticoagulant therapy was stopped and INR evaluated prior to implant surgery. With the help of computerized tomography, four Nobel Biocare Tapered TiUnite narrow platform implants were placed anteriorly between the mental foramina. An implant-supported mandibular overdenture was fabricated. Locator attachments provided retention and stability for the prosthesis. This helped improve the patient's quality of life.
一位长期佩戴假牙的患者出现了严重的牙槽骨吸收，导致下颌骨萎缩。颏部骨高度为10毫米。下牙槽神经和颏孔靠近下颌骨嵴。颏部区域可用于骨内种植体植入。患者为一名83岁的白人男性，存在医疗并发症。在种植手术前停用了抗凝治疗并评估了国际标准化比值（INR）。在计算机断层扫描的帮助下，在前颏孔之间植入了4枚诺贝尔生物科技公司的锥形钛易耐窄平台种植体。制作了种植体支持的下颌覆盖义齿。Locator附着体为义齿提供了固位和稳定性。这有助于提高患者的生活质量。
