Overview: Basic information on the snap ring

It is often used for missing free ends of posterior teeth, abutment teeth are premolars or canines, and crowns are short or tapered. The tip of the clasp is located in the undercut area of u200bu200bthe labial (buccal) surface of the abutment, bypassing the occlusal rest on the distal surface of the abutment, and then turning to the non-undercut area of u200bu200bthe lingual surface of the abutment, on the mesial lingual side of the abutment It is connected with the base or the connecting rod through the connecting body. Or, the tip of the snap ring arm is located in the undercut area of u200bu200bthe lingual surface of the abutment, and is connected to the distal support through the non-undercut area of u200bu200bthe abutment, and then turns to the non-undercut area of u200bu200bthe mesial and buccal side. snap ring. Both are cast snap rings. Because the distal occlusal support is not directly connected with the base or the connecting rod, the occlusal force is first transmitted to the tissue under the base through the artificial teeth and the base, which can reduce the occlusal force of the abutment and play a role in stress interruption.
