The aim of this clinical report is to describe a maxillary full-arch implant supported restoration with immediate loading performed by means of an entirely digital work flow with photogrammetric system and intraoral scanning. A female patient with an edentulous maxillary arch attended the dental clinic seeking a maxillary fixed restoration. After treatment planning, 6 implants were placed using a surgical splint fabricated digitally by intraoral scanning of her previous removable prosthesis. Multiunit abutments were fitted, and 2 digital impressions were taken, one with a photogrammetric system for determining implant positions and the other with an intraoral scanner for soft tissue registration. The acrylic resin structure of the immediate prosthesis was milled and placed within 8 hours of implant surgery. This provisional structure fitted correctly and provided adequate esthetics and function. Radiographic and clinical follow-up after 24 months observed adequate implant evolution.
本临床报告的目的是描述通过使用摄影测量系统和口内扫描的全数字化工作流程进行的上颌全牙弓种植体支持的即刻加载修复。一名上颌无牙弓女性患者前往牙科诊所寻求上颌固定修复。经过治疗计划，通过对她之前的可摘义齿进行口内扫描数字化制作的手术导板植入了6颗种植体。安装了多单位基台，并采集了2次数字印模，一次使用摄影测量系统确定种植体位置，另一次使用口内扫描仪进行软组织记录。即刻修复体的丙烯酸树脂结构在种植手术后8小时内铣削并就位。这个临时结构贴合良好，提供了足够的美观和功能。24个月后的影像学和临床随访观察到种植体进展良好。
