Teeth loosening are caused by insufficient supporting tissue, inflammation of periodontal tissue, or occlusal trauma, which is one of the main clinical symptoms of periodontitis. A digital technique for fabricating resin-bonded splinting fixed partial dentures (S-FPDs) is presented. It restores the missing mandible anterior teeth and splints the adjacent periodontally mobile teeth of the patient at the same time. The S-FPDs is designed and fabricated by computer-aided design and computer-aided manufacturing (CAD/CAM) technology with flexible PMMA material. The workflow is straightforward, convenient, and accurate. Meanwhile, the restoration can meet the esthetic requirements and help with the stability of adjacent loosening natural teeth spontaneously. It could be considered a medium-term provisional restorative treatment option, but further controlled investigations still be needed.
牙齿松动是由支持组织不足、牙周组织炎症或咬合创伤引起的，这是牙周炎的主要临床症状之一。本文提出了一种用于制作树脂粘结夹板固定局部义齿（S-FPDs）的数字技术。它同时恢复了缺失的下颌前牙，并固定了相邻牙周移动的牙齿。S-FPDs 是通过计算机辅助设计和计算机辅助制造（CAD/CAM）技术与弹性 PMMA 材料设计和制作的。工作流程简单、方便、准确。同时，修复体可以满足美观要求，并有助于自然松动邻牙的稳定性。它可以被认为是一种中期临时修复治疗选择，但仍需要进一步的对照研究。
