ABSTRACT

In order to accomplish the designed treatment objective, it isdeemed necessary to provide sufficient retention of the removable appliance. In this regard, clasps such as Adams, Schwars arrowhead Duyzing, Jackson, Crozat, ball, triangular, C and so forth, have been developed. Furthermore as much importance must be given to the level of comfort provided by the clasp as is given to its retentive property, particularly in appliances where long, term wear is essential. It is concerning these two properties that Ishigami proximal clasps render the greatest contribution through their high retentive capacity and ease of placement in the mouth. Hence, in spite of being developed originaly for dentures, tnese clasps may be effectively accomotated in orthodontic appliances. In this paper, experiences acquired through practical application of Ishigami proximal clasps, are presented.
