Abstract:

Objective To evaluate the clinical effect of the application of the new Quartz SplintTM high strength silica fiber splint in keeping the orthodontic teeth,and to provide the basis for choosing appropriate orthodontic retainer. Methods A total of 62 patients needing local strengthening retainer after completed orthodontic treatment were selected.The patients were divided 3-month,6-month and 12-monthgroups according to the follow-up time.Quartz SplintTM high strength silica fiber splint was used to fox the labial teeth.Visual and instrument examination were used to check wether there were off-sites of retainers in various groups,teeth gap and the presence of recurrent dislocation;the periodontal health status was observed including probing depth(PD),bleeding index(BI),and plaque index(PLI). Results 60 patients using Quartz SplintTM high strength silica fiber splint were stable without frature while the periodontal tissue revealed no significant changes in all 62 patients.Only 2 cases of Quartz SplintTM high strength silica fiber splint in 6 months and 12 months respectively had individual off-sites without breaking.During 12-month follow-up period,the total intact rate of Quartz SplintTM high strength silica fiber splint was 96.77%,and the patients had healthy periodontal conditions. Conclusion The stable clinical effect can be obtained by the application of Quartz SplintTM high strength silica fiber splint for scattered clearance of the front teeth area or rotated teeth after orthodontic.
