Direct Composite Resin Restoration of a Class IV Fracture by Using 3D Printing Technology: A Clinical Report.
The journal of prosthetic dentistry/The Journal of prosthetic dentistry(2021)
摘要
Mimicking the appearance of the adjacent natural tooth is challenging when restoring a fractured anterior tooth. This clinical report describes a modified index technique for restoring a class IV defect. A replica of the restored tooth was fabricated with computer-aided design and 3D printing technology, which precisely mimicked the contralateral incisor. Labial and lingual silicone indices were developed on the replica to transfer the designed contour to the tooth to achieve a highly esthetic and precise restoration.
