There has been shown the efficiency of using attachments that can be adapted for clinical crowns of any height. The combination of fixing elements of an attachment determines sufficient fixation to provide high masticatory efficiency, and spatial stabilization of a denture, but at the same time it restricts partially, not completely, denture lability when functioning that is typical of rigid attachments and telescopic systems. The restricted lability determines a reduced load on parodontium of abutment teeth due to the redistribution of a part of masticating pressure on alveolar mucosa. This attachment provides the distribution of masticating pressure along the long axis of an abutment tooth; it is physiological, and significantly reduces the risk of traumatic occlusion, mobility, and displacement of abutment teeth. The reduced load on abutment teeth parodontium suggests expansion of indications for using small saddle dentures with this attachment in patients with periodontal diseases complicated by partial loss of teeth.

A new clasp to fix small saddle prostheses was designed to improve the quality of prosthetic unilateral free-end saddle restoration. Unlike the known ones, the clasp can be adapted for clinical crowns of any height (particularly useful for low crowns) as no standard elements are required to be fixed on prosthesis. Prosthesis retention is independent of the height of coronal part and the evidence of its survey line. Gentle preparation of abutment teeth allows grinding off hard tooth issues minimally. The combination of fixing elements of a single clasp provides sufficient fixation to achieve high masticatory efficiency and prosthesis spatial stabilization but at the same time only partially limits its lability in mastication. The clasp can be used in free-end saddle restoration both in maxilla and mandible, and especially in patients with periodontal diseases complicated by partial tooth loss. Source
