1 Famdent Practical Dentistry Handbook Vol. 14 Issue 4 July - Sep. 2014 we need more elaborate impression techniques. A removable partial denture fabricated from a one-stage impression, which records only the anatomic form of basal seat tissues, places more of the masticatory load on the abutment teeth and that part of the bone that underlies the distal end of the extension base [7] . McCracken proposed the altered cast technique with the selective tissue placement impression [3] . Christensen, in a less complicated technique, suggested to take the impression of the edentulous arch with an elastomeric material in a custom tray, then to cover this initial layer and the dentate areas with a lighter viscosity elastomeric impression material [8,9] . Hindels introduced his functional technique in order to equalize the load between the teeth and the edentulous ridges [10,11] . His technique consisted of having a mucostatic impression of the edentulous ridges followed by a pickup impression with digital compression of the first impression through holes prepared on the impression stock tray. The objective of any functional impression for distal extension removable partial dentures is to provide maximum support for prosthetic denture base and solid occlusal contacts between natural and artificial teeth with minimum base movement during function. [7] We propose a modification of the Hindels impression technique in order to simplify the procedure without jeopardizing its functionality. Abstract The construction of a removable partial denture in distal extension cases is a delicate procedure since the prosthesis is supported by two different tissues, namely teeth and mucosa. Different resiliency of these supporting tissues may lead to the instability of the prosthesis. This paper describes a functional impression technique that aim to equalize the masticatory load between teeth and edentulous areas thus reducing the instability of the partial denture during function and preserving the residual teeth. The construction of removable partial denture is a delicate task especially when the edentulous space has distal extension sectors. In these distal extension saddles removable partial dentures are supported by teeth and edentulous ridges, this mixed support will inflict movements of the prosthesis under function because of the different nature of supporting structures. Different techniques have been proposed for the construction of removable partial dentures in distal extension cases where the management of the difference of resiliency in the supporting tissues is an issue [1-4] . The purpose of these techniques is to distribute more evenly the forces between the edentulous ridges and the abutment teeth and gain stability for the prosthesis [5] . The idea of recording tissues of different resiliencies namely teeth and edentulous ridges with a single impression material was proved unrealistic [6] , that is why Impressions For Removable Partial Dentures Revisited: A Functional Approach Dr. Boulos Paul has a private practice in Dentistry and Removable prosthodontics specialist in Beirut –Lebanon since 1982. He joined the School of Dentistry at Saint Joseph University (Beirut- Lebanon) as an instructor in the Removable Prosthodontics Department in 1982. He has been the Head of the Removable Prosthodontic Department (2007-2010) and Director of Graduate Removable Prosthodontics Program since October 2010. He has been associated with American National Board of Dentistry. He has done Master of Science in oral biology in July 2005 along with PhD in oral biology –July 2007. Dr Boulos Paul J. Dr. Elie Daou was born in July 1969, in Lebanon. He was graduated as Dental surgeon in 1994, from Saint Joseph University in Beirut. Then he got a Master in Sciences in 1999 and a DES in Prosthodontics in 2002 from the same university. Besides his private practice, he was in Department of Removable Prosthodontics till 2005. He is a Chief Clinical instructor in the Department of Prosthodontics, at the Lebanese University (LU) in Beirut. He is preparing a PhD at the LU. Dr. Elie Daou
