Support of removable partial dentures in situations with a unilaterally missing canine and a curved edentulous ridge.
The load and movement of abutments and removable partial dentures were examined in situations with a unilaterally missing canine and a curved edentulous ridge. These measurements were performed on a model adapted to intraoral conditions. In this simulation, removable partial dentures supported by incisors may result in failure. Spring rest support results in significantly reduced articulation vertically and horizontally when compared with solid rest support and avoids periodontal overloading.
