Objective:
To study the method for preparing removable partial denture using Saddle-Lock hidden-clasp and evaluate its clinical effect.
Method:
Casting process was adopted for the preparation of the clasp, which was fixed at the points on the mesial and distal surfaces of the abutment tooth. The clinical records of 305 patients treated with such removable partial dentures were reviewed.
Results:
Within a follow-up period of 6 years, 295 of the 305 patients retained good abutment condition and were satisfied with the denture that was capable of easy wearing and removing.
Conclusions:
Removable partial denture made by Saddle-lock hidden-clasp exhibits good performance in fixation and stability. As an innovation of traditional design of partial denture clasp, it is simple to prepare and well received by the patients with good clinical effect.
