Clinical effect of magnetic attachment denture in patients with chronic periodontitis

ObjectiveTo study the clinical effects of abutment teeth of magnetic attachment in patients with chronic periodontitis.MethodsNineteen patients were restored with removable partial dentures(RPD)with magnetic attachments,including forty-five abutment teeth of magnetic attachments. The periodontal probing depth(PD),mobility of abutment teeth and the stability of the dentures were observed after restoration for three to five years. SPSS 19.0 software package was used for statistical analysis.ResultsRetention rate of abutment teeth in these cases was 91.11% in three years. The PD of abutment teeth was(2.17 ± 0.77)mm before restoration and(1.89 ± 0.67)mm after three years,the latter being lower than the former(P 0.05). The mobility of abutment teeth increased in some cases,which may be because of the loss of stability of the removable partial dentures.ConclusionMagnetic attachment can protect weak abutment teeth in chronic periodontitis patients.
