Abstract
Purpose: To investigate the effect of chair side computer aided design/computer aided manufacturing (CAD/CAM) crown restoration technique in the treatment of posterior tooth defects and its influence on chewing ability.
Methods: A total of 98 patients with posterior dental defects treated from June 2023 to May 2024 were selected and divided into control group (traditional silicone rubber impression crown repair) and experimental group (chair side CAD/CAM crown repair) according to different treatment methods. The repair effect, masticatory efficiency and bite force before and after treatment, periodontal index, complication rate and patient satisfaction were compared between the two groups. SPSS 22.0 software package was used for statistical analysis of the data.
Results: One month after treatment, there was no significant difference in comfort, edge fit, color matching and surface texture between the experimental group and the control group(P＞0.05). The experimental group was significantly better than the control group in adjacency contact, secondary caries prevention and gingival status (P＜0.05). After treatment,gingival index and plaque buildup, gingival sulcus bleeding index, the degree of gum health improvement of loose tooth in the experimental group were significantly better than in the control group(P＜0.05). There was no significant difference in the incidence of complications between the two groups after treatment(P＞0.05). Repair satisfaction of the experimental group was 96.15%, which was significantly higher than 86.96% of the control group(P＜0.05).
Conclusions: Chair side CAD/CAM crown restoration technology has good application value in the treatment of patients with posterior dental defects, which can significantly improve the repair effect, improve chewing ability, effectively inhibit gingival inflammation and dental plaque generation, reduce the risk of gingival bleeding and tooth loosening, and significantly improve patients' satisfaction.
