Abstract:
Objective To evaluate the abutment periodontium condition after restored with the distal - extension extracoronal attachment dentures. Methods 20 mandibular distal- extension cases were followed up, to measure the gingival index(GI) and plaque index(PLI) of the distant - abutments before restored with attachment dentures and after restored for one month, six months and one year; to compare the length of distant alveolar bone before restored with that after restored one year by taking digital stomatology tomogram photos. Results There were not significantly different in the PLI of distant- abutment between before repaired and after repaired one month, six months, one year (P>0.05). There were not significantly different in the GI of distant - abutment between before repaired and after repaired one month, six months(P>0.05), but the GI of distant - abutment after repaired one year was significantly higher than that before repaired(P<0.05). There were no significant differences on the length of distant alveolar bone in distant- abutment before repaired and after repaired one year(P>0.05). Conclusion It is important to protect the periodontal health of the abutment when restored with distal- extension extracoronal attachment dentures. It is necessary to examine periodically after restored in order to keep the periodontal health of the abutment.
