Book Description
Porcelain-fused to-metal (PFM) crowns have been considered the gold standard for the repair of damaged teeth. PFM crowns have good mechanical properties, satisfactory esthetic results, and an acceptable biological quality needed for periodontal health. However, PFM crowns have some limitations that may limit their use. The fabrication of PFM is a highly technique-sensitive procedure that consists of investing wax patterns and casting precious metal alloys. Furthermore, the esthetic of PFM crowns is limited by the metal framework and the layer of opaque porcelain needed for masking the underlying metal grayish shade. Recently the cost of precious metals has risen markedly making PFM relatively unattractive from an economic standpoint. Ceramic crowns have been tried in the last four decades to replace PFM crowns and overcome their esthetic limitations. However, the use of all-ceramic crowns has been challenged in practice by the uncertainty of their physical proprieties and their resistance to fracture and chipping. Policy makers require information on the relative benefits and costs associated with different types of crown materials in order to support reimbursement decisions. The objective of this review is to evaluate the clinical and cost-effectiveness of dental PFM and all-ceramic crowns.

Book Description
The soaring costs of precious metals in recent times makes metal-ceramic crowns economically less desirable, while increasing the use of all-ceramic fixed dental prostheses (FDPs). The aim of this review is to summarize the available evidence concerning the clinical effectiveness measured by longevity and the costs-effectiveness of porcelain-fused-to-metal (PFM) and all-ceramic crowns to support reimbursement decisions.

Book Description
The aim of this review is to summarize the available evidence concerning the clinical effectiveness measured by longevity and the costs-effectiveness of PFM and all-ceramic crowns to support reimbursement decisions. [...] The position of the crown in the mouth did not significantly alter the survival of metal-ceramic crowns or all-ceramic crowns made out of leucite or lithium-disilicate, densely sintered alumina, or glass-infiltrated alumina. [...] Critical Appraisal of Individual Studies The included systematic review was critically appraised using the AMSTAR tool,5 and the non- randomized studies were critically appraised using the Downs and Black checklist for measuring quality of studies.6 Summary scores were not calculated for the included studies; rather, a review of the strengths and limitations of each included study were described n [...] The strengths and limitations of the individual studies are summarized in Appendix 3. Porcelain-Fused-to-Metal Crowns versus All-Ceramic Crowns 3 SUMMARY OF EVIDENCE Quantity of Research Available A total of 180 citations were identified in the literature search. [...] The countries of origin of the primary studies of the systematic review4 were not declared, and all non-randomized studies in this review were conducted at single private centers in Germany8 or Italy.9,10 Therefore, it is unknown whether the reported findings are generalizable to the Canadian context.

Book Description
There is a no more rewarding experience in restorative dentistry than to duplicate to perfection the colour, texture and surface anatomy of the human tooth. Dental porcelain is the closest match to tooth enamel of all our restorative materials but is perhaps the most difficult to use in dental practice. A study of the science of dental porcelain will enable the dentist or technician to perfect his art since it develops an increasing awareness of the fundamental problems in construction. Preparation design, the stresses developing in porcelain restorations, the influence of opaque backgrounds on colour, surface reflectivity and light transmission in crowns are some of the complex factors that influence the success of a porcelain veneer restoration. A survey of metals, bonding systems, cements and impression materials will enable the clinician to select his materials with greater confidence. New research on the shoulder preparation for the veneer crown also sheds light on the controversy of the bevel versus the butt joint. The author has attempted to rationalise the use of both metal and alumina reinforced ceramics and to show how no ingle system can be applied universally if optimum aesthetics is to be achieved.

Book Description
In Fixed Restorations: A Clinical Guide to the Selection of Materials and Fabrication Technology, the authors Irena Sailer, Vincent Fehmer, and Bjarni Pjetursson have created a timely and comprehensive guide to modern reconstructive dentistry. The book is divided into four parts: basic information regarding materials and production processes, step-by-step clinical procedures with extensive case presentations, long-term outcomes, and management of complications. With over 2000 clinical images and diagrams, backed up with the scientific evidence for recommendations, the best practice for tooth- and implant-supported fixed restorations is clearly described. The vast clinical and technical knowledge and experience of the authors has resulted in a unique textbook that will aid in decision making regarding material selection and procedures for all patients in need of fixed restorations.

Book Description
In this second volume, with numerous color photographs and diagrams, detailed techniques for making metaloceramic and alumina-reinforced crowns and bridges are presented. Special effects in dental procelain, the Wedge Technique, development of correct anatomy, methods for avoiding loss of detail during glazing, casing technique, surface finishing of metal - these topics and more are critically examined in light of current research.

Book Description
The growth of implant and fixed prosthodontics practices in dentistry has created a rapidly increasing demand for advanced ceramics and ceramic processes. Innovations in ceramics and ceramic processes are vital to ensure reliable and affordable dental-restoration solutions with aesthetically pleasing outcomes. The work aims to engage the bioceramics and engineering communities to meet the challenges of modern dental restoration using advanced ceramics. Incorporating fundamental science, advanced engineering concepts, and clinical outcomes, the work is suitable for bioceramicists, ceramics manufacturers, dental clinicians and biologists. - State-of-the-art-coverage encompasses bioresorbable ceramics for bone regeneration and bioactivating surfaces of inert, high-strength ceramics for implantation, keeping research knowledge appropriately updated - Discusses transition from the baseline stable and physically stiff ceramics research into engineering of highly coherent laminate composites for prosthetic crowns and bridges - Showcases current feasible techniques for producing, in cost-effective and materials-saving ways, long-lasting individualized ceramic components with biocompatibility, complexity and high precision
