Objective To analyze the effect of all-porcelain crown and onlay on posterior tooth defect repair and periodontitis reaction.Methods Fifty cases of posterior dental defects treated in our department from February 2022 to May 2023 were divided into control group(odd-numbered,all-porcelain crown restoration)and onlay group(even-numbered,onlay restoration)with 25 cases each.The repair effect,periodontitis response,oral health index and complication rate were compared between the two groups.Results The wearing time and overall recovery time of the onlay group were shorter than those of the control group(P＜0.001).The periodontal normal rate in the onlay group was higher than that in the control group(P＜0.05).gingival index,plaque index,sulcus bleeding index of the onlay group after repair were lower than those of the control group(P＜0.05).The complication rate of the high inlays group was close to that of the control group(P＞0.05).Conclusions In the repair of post-dental defects,the use of onlay repair can achieve relatively better repair effects,shorten the time for patients to wear the prosthesis,accelerate the rehabilitation process,have a positive impact on the reduction of periodontitis reaction and the improvement of oral health.The risk of its complications is small,and the overall effect is better.
