Effect and Impact on Adjacent Teeth Relationship and Occlusion of Porcelain High Inlay Restoration in the Treatment of Elderly Permanent Tooth Crown Defects
Objective:To explore the effectiveness of porcelain high inlay restoration in the treatment of crown defects in elderly permanent teeth and its impact on the restoration of adjacent teeth relationship and oc-clusion.Methods:A retrospective analysis was conducted on the clinical data of 116 elderly patients(116 af-fected teeth)with crown defects treated at the People's Hospital of Guang'an from September 2020 to October 2022.Based on different restoration materials,patients were divided into the resin group(57 cases,57 affect-ed teeth)and the porcelain high inlay group(59 cases,59 affected teeth).The resin group underwent direct resin filling,while the porcelain high inlay group underwent porcelain high inlay restoration.Six months after restoration,the restoration effects,aesthetic outcomes,occlusion conditions immediately after restoration and 6 months later,and periodontal health(gingival index[GI],plaque index[PLI],gingival bleeding index)before and after restoration were compared between the two groups.Results:Six months after restoration,the porcelain high inlay group showed higher USPHS satisfaction,aesthetic scores,and percentage of centric oc-clusion on the affected side than the resin group(P<0.05).The gingival bleeding index,GI,and PLI levels were lower than those in the resin group(P<0.05).Conclusion:Porcelain high inlay restoration has a signif-icant effect in the treatment of crown defects in elderly permanent teeth,and it is superior to direct resin filling in terms of aesthetic outcomes,occlusal function,and periodontal health.
