对比分析 Lava Ultimate 优韧瓷高嵌体与 SonicFill 声波树脂修复对 根管治疗后大面积牙体缺损的修复效果.

Objective: To compare the effects of lava ultimate high toughness ceramic inlay and sonicfill acoustic resin in the repair of large-area tooth defects after root canal treatment. Methods: 124 patients with large-area tooth defects after root canal treatment treated in our hospital from January 2019 to January 2022 were selected as the research objects. They were divided into group A (62 cases) and group B (62 cases) according to the method of tooth restoration. Group A was repaired with lava ultimate high toughness porcelain inlay, and group B was repaired with sonicfill acoustic resin. The clinical efficacy, gingival index (GI) and plaque index (PLI), complications and patient satisfaction were compared between the two groups at 6 months and 1 year. Results: (1) There was no difference between group A and group B in the classification of edge tightness, shape, color, fracture and secondary caries of abutment teeth in the modified USPHS standard at 6 months and 1 year after restoration (P>0.05); (2) The GI and PLI of group A and group B at 6 months and 12 months after repair were significantly lower than those before repair (P<0.05), but there was no difference between the two groups at different times (P>0.05); (3) The total satisfaction of repair in group A was higher than that in group B (P<0.05); (4) The total incidence of complications in group A and group B were 3.23% and 4.84% respectively. There was no difference between the two groups (P>0.05). Conclusion: Lava ultimate superior tough porcelain high inlay and sonicfill acoustic resin have the same effect on the treatment of large-area tooth defects after root canal treatment. They can effectively ensure the appearance recovery, tightness and occlusion of tooth defects, which is conducive to periodontal health, but the high inlay satisfaction is high. [ABSTRACT FROM AUTHOR]
