summary Changes in the retention force of six prefabricated spherical and cylindrical
attachments were examined in vitro under continuous loading. The testing machine …

I recision-type attachments are commonly used to enhance the retention and stability of
overdentures. This not only adds considerably to the overall cost of the treatment but also …

Objectives: Wear of attachments leads to a loss of retention and potentially reduces the
function of complete dentures. This study evaluated the retention force changes of different …

Background Mandibular two‐implant‐retained overdentures were suggested as first choice
of treatment for edentulous mandibles. However, wear of the attachments may reduce their …

summary This study evaluated retention force and fatigue resistance of two overdenture
attachment systems. Twenty samples (O‐ring and Bar‐Clip) from two manufacturers …

Statement of problem. There are few research studies concerning prefabricated posts
overdenture attachment systems using multiple pull cycles. Purpose. This study tested 6 …

Background It is necessary to know the in vitro behavior of different attachment systems to
be used clinically. The evolution of retention capacity over 10 years (14,600 insertion/de …

The aim of this study was to validate an original portable device to measure attachment
retention of implant overdentures both in the lab and in clinical settings. The device was built …

Three types of retainers (wrought wire clasp, Aker's cast clasp, and conical crown telescopic
retainer) designed for distal‐extension removable partial dentures (RPDs) were assessed in …

Objective This in vitro study evaluated the influence of implant angulations on the retentive
behavior of two overdenture attachments during cyclic dislodging. Methods Models …
