Abstract：AIM: To evaluate the clinical prosthetic effects of gingival retractor in aesthetic restoration of anterior teeth. METHODS: 28 units of anterior full crown in 23 patients were randomly divided into 2 groups (n=14). The tooth shoulder was prepared with gingival retractor in GR group and that with retraction cord in RC group. The teeth in both groups were restored using Zirconia full ceramic crowns. Then the gingival injury, shoulder position,marginal adaptation and morphology of finishing line in all patients were evaluated in plaster models. RE-SULTS:Marginal adaptation did not show significant difference between 2 groups(P>0.05). However, GR group showed better results for of gingival injury control, shoulder position accuracy and morphology of finishing line (P<0.05). CONCLUSION: In aesthetic restoration of anterior teeth, the application of gingival retractor during sub-gingival shoulder preparation has positive impact for gingival injury control, accurate shoulder position and the quality of morphology of finishing line.
