Abstract: Objective: To investigate the clinical effect of layered nano-composite resin prosthetics and indirect guide plate technology on the esthetic restoration of incisor diastema. Methods: 50 patients with incisor diastema who visited Hospital of Traditional Chinese Medicine of Lianyungang from January to December, 2011 were involved in this study. The teeth were treated with layered nano-composite resin prosthetics and indirect guide plate technology to close the diastema. The patients were semi-annually followed-up from January 2012 to June 2014. Results: By June 2014, 48 out of 50 patients had successful clinical effects and 2 patients were failed. Conclusion: Incisor diastema can be satisfied treated with layered nano-composite resin prosthetics and indirect guide plate technology.
