Study on the effect of dental implant restoration in patients with chronic periodontitis
Objective To study the effect of dental implant restoration in patients with chronic periodontitis.Methods 80 patients with dental implant restoration were selected,including 40 cases of healthy periodontitis patients(control group)and 40 cases chronic periodontitis patients(observation group).All patients received dental implant restoration.The periodontal index,matrix metalloproteinase[matrix metalloproteinase-9(MMP-9),matrix metalloproteinase-8(MMP-8),matrix metalloproteinase-2(MMP-2)]and masticatory function scores before and after treatment were compared between the two groups;alveolar bone resorption was analyzed in the observation group.Results Before treatment,the periodontal probing depth,sulcus bleeding index,plaque index and gingival papilla in the observation group were(1.58±0.20)mm,(0.28±0.13),(0.50±0.13)and(2.78±0.56),which were higher than(1.43±0.15)mm,(0.14±0.11),(0.40±0.12)and(2.32±0.57)in the control group(P<0.05).After treatment,the periodontal probing depth,sulcus bleeding index,and plaque index of the observation group were(1.54±0.23)mm,(0.25±0.17),and(0.47±0.15),which were not significantly different from(1.56±0.21)mm,(0.21±0.16),and(0.49±0.14)of the control group(P>0.05).The gingival papilla was(2.05±0.50)in the observation group,which was higher than(0.98±0.42)in the control group(P<0.05).Before and after treatment,MMP-9,MMP-8,and MMP-2 in the observation group were significantly higher than those in the control group(P<0.05).Before and after treatment,there was no significant difference in masticatory function score between the two groups(P>0.05).Alveolar bone resorption of patients in the observation group was(1.29±0.25)mm after 1 month of treatment,(1.52±0.39)mm after 3 months of treatment,and(1.69±0.47)mm after 5 months of treatment.Conclusion The implementation of dental implant restoration for patients with chronic periodontitis has a significant effect.
