【Abstract】 Objective To observe the clinical effects of fiber posts in restoring maxillary anterior teeth after
surgical crown lengthening by piezosurgery. Methods After root canal therapy, 32 teeth from 27 patients were
lengthened with piezosurgery. After 6 weeks, they were restored by fiber posts, dual cure resin cement, composite res-
in material. And then, zirconia crowns were applied to restore them. The patients were observed the restoration effects
by clinical results and X-ray. Results The 32 teeth from 27 patients were followed up for 1~3 years, with 29 teeth
successfully restored (90.6%) and 3 teeth unsuccessfully restored (9.4%). Conclusion A satisfactory treatment ef-
fects could be achieved by surgical crown lengthening with piezosurgery and fiber posts in restoring maxillary ante-
rior teeth.
