Abstract
Objective To analyze the effects of titanium alloy and stainless steel implant abutment screws on the incidence of tooth loss and periodontal tissues in orthodontic patients.Methods The clinical data of 103 orthodontic patients admitted to Sanmenxia Central Hospital from August 2021 to January 2024 were retrospectively analyzed.Fifty-one patients treated with stainless steel implant abutment screws were included in the control group,and 52 patients treated with titanium alloy implant abutment screws were included in the study group.The implant success rate,imaging indicators before and after treatment,periodontal tissue conditions,incidence of tooth loss,fracture rate,and adverse reactions were compared between the two groups.Results The implant success rate of the study group was 92.31%,which was not statistically different from 90.2%of the control group(P>0.05);6 months after treatment,the changes in imaging indicators of the study group were greater than those of the control group,and the difference was statistically significant(P<0.05);3 months after treatment,the bleeding index,periodontal depth,and plaque index of the study group were lower than those of the control group,and the difference was statistically significant(P<0.05);there was no statistically significant difference in the incidence of tooth loss and fracture rate between the two groups at 3 and 6 months after treatment(P>0.05);the adverse reaction rate of the study group was 3.85%,which was lower than 7.84%of the control group,and the difference was no statistically significant(P>0.05).Conclusions Both titanium alloy and stainless steel implant abutment screws can improve the incidence of tooth loss and fracture rate in orthodontic patients and enhance the clinical treatment effect.However,compared with stainless steel implant abutment screws,titanium alloy implant abutment screws can significantly improve imaging indicators and promote periodontal tissue recovery.关键词
