[The "retention complex" and its relationship to abutments: what is today's thought?]
Abstract:
Based up on a review of the literature, the authors have tried to define the possible responsibility of each component of a retention complex (occlusal support--cross-piece--locking arm--retention arm) in the mechanical mobilisation of abutment teeth supporting partial removable prostheses (Kennedy, Class I and II). Taken separately, all these components are intrinsically able to mobilise the teeth. However, no "modern" retention complex (Nally & Martinet--R.P.I.--R.P.A.--"equipoise"...) should jeopardize the abutments, as long as they have been correctly prepared as well as the entire prosthesis.
