Abstract

This article describe a new device that can be used for clinical measurement of retention for implant retained overdenture. This device overcomes the problems of the used techniques in terms of vertical direction of force. The force will be perpendicular to the patient’s occlusal plane. The method allows also complete standardization between time intervals.
The device consists of plate form with vertical arms and middle screw that move vertically to guide the movement of the force meter in vertical direction. A fork is used to connect the force meter to the implant retained prosthesis through four hooks to canine and first premolar areas bilaterally moving it completely vertical.
