Effects of total anatomical multi-layer zirconia crown and 3D printed zirconia ceramic crown based on intraoral digital impression technology in the restoration of maxillary single anterior teeth
Objective To analyze the effects of total anatomical multi-layer zirconia crown and 3D printed zirconia ceramic crown based on intraoral digital impression technology in the restoration of maxillary single anterior teeth.Methods A total of 56 patients with restoration of maxillary single anterior teeth admitted in our hospital from July 2020 to July 2022 were selected as the research objects.According to the difference of treatment methods,the patients were divided into group Ⅰ(28 cases,total anatomical multi-layer zirconia crown treatment based on intraoral digital impression technology)and groupⅡ(28 cases,3D printed zirconia ceramic crown treatment based on intraoral digital impression technology).The therapeutic effects of the two groups were compared.Results There was no significant difference in the total effective rate of restoration between the two groups(P>0.05).After treatment,the chewing function of the groupⅠ was lower than that of the group Ⅱ,the scores of gingival index(GI)and plaque index(PLI)were higher than those of the groupⅡ,the probing depth(PD)and attachment loss(AL)were longer than those of the group Ⅱ(P<0.05).After treatment,the angle of sella-nasion-supramental(SNB),angle of sella-nasion-subsipmale(SNA)and angle of subsipmale-nasion-supramental(ANB)in the group Ⅰ were greater than those in the group Ⅱ(P<0.05).The scores of White Esthetic Score(WES)and Pink Esthetic Score(PES)in the groupⅠwere higher than those in the group Ⅱ,and the total incidence of adverse events was lower than that in the group Ⅱ(P<0.05).Conclusion The total anatomical multi-layer zirconia crown and 3D printed zirconia ceramic crown based on intraoral digital impression technology can achieve ideal curative effect in the restoration of maxillary single anterior teeth,but the former can effectively guarantee the prognosis of patients compared with the latter,while the latter has higher aesthetic appeal than the former.
