Removable Titanium-alloy Splint In Fixing Loosen Teeth Of Adult Periodontitis

objective: To investigate the effectiveness of removable Titanium -alloy splint in fixing the loosen teeth of adult periodontitis. Methods: Applying 3 designing projects in the three groups. Recording the patients' tooth mobility , probing depth , attachment loss and alveolar bone resorption, then compared the data. Results: Before treating, there were no statistical differences between Titanium-alloy splint group and non-splint, Co-Cr-alloy splint group in tooth mobility, probing depth, attachment loss and alveolar bone resorption (p>0.05). After 1 year' treating, Titanium-alloy group and non-splint group were significantly different in tooth mobility (p<0.05), otherwise, Titanium-alloy groupand Co-Cr-alloy group were not significantly different in it(p>0.05). Moreover there were no statistical differences in probing depth , attachment loss and alveolar bone resorption between Titanium-alloy group and non-splint, Co-Cr-alloy group (p>0.05). The effectiveness were both 90% in Titanium and Co-Cr alloy group, yet non-splint group was 40%.(according to Zhoushumin' norm). The effectiveness of two kinds of splints was not significant different(p>0.05), but it was different compared to the non-splint group(p<0.05). Conclusions:1. Compared to non-splint group, Titanium-alloy and Co-Cr-alloy splint groups had curative effectiveness in fixing loosen teeth of adult periodontitis.2.R'emovable casting periodontal splints were not only having effectiveness infixing the loosen teeth , but also sometimes in repairing missing teeth. So, theywere perfect designing project in treating periodontal disease.3. The adult periodontitis patients shall wear splints after being treated perfectperiondotitis initial treatment and shall persist in counterchecking in order toensure clinical curative effect.
