Abstract:

Objective To investigate a case of dental treatment under general anaesthesia using a digital model to assist in the surgery of severe low grade childhood caries. Methods Preoperatively, the patient’s mouth was scanned using a digital oral scanner, and the electronic jaw frame was used to determine the orthodontic occlusal relationship and then a digital resin model was created by 3D printing. The preformed crown was trimmed on the model, and the trimmed preformed crown was worn directly after the intraoperative dental treatment. Results The use of digital model shortened the treatment time, restored the shape and occlusal relationship of the child’s teeth and resulted in no postoperative occlusal discomfort. Conclusion The use of digital models can improve the outcome of dental treatment for children with S-ECC under general anesthesia.
