Five-year clinical results of zirconia frameworks for posterior fixed partial dentures Sailer et al 2007 Studies using finite-element analysis demonstrated that during occlusal loading the highest stress within FPDs was located at the gingival side of the connector area. Zirconia exhibits the highest bending strength (900 MPa) . The preprosthetic and prosthetic treatments were toughness

Current concepts in gingival displacement Donovan et al 2004 This article discusses the concepts of gingival displacement for optimal impressions Inadequate impressions are frequently forwarded to commercial laboratories, and the chief deficiency seen in such impressions is inadequate recording of the cervical finish lines.  The primary reason for not adequately capturing marginal detail is deficient

A review of contemporary impression materials and techniques Donovan et al 2004 This article outlines the ideal properties of impression materials and explains the importance of critical manipulative variables. Available impression materials are analyzed relative to these variables, and several ‘‘specialized’’ impression techniques are described. Ideal properties  1.Elastic recovery:  Elastomeric impression materials must be able to
