Advances in the medical sciences along with rapid increase in the specialized and better treatment modalities, certainly prolonged the human life with a drastic increase in the number of elderly in the past few decades. Tooth loss is one of the manifestations of aging. Dentures and dental implants are the major prosthetic devices given to restore physiological and esthetic functions of oral tissues of edentulous or partially edentulous patients. Complete and partial dentures based on polymeric compositions are the most popular devices since the cost of dental implants and metal-base dentures are much higher. Among the polymers, poly (methyl methacrylate) (PMMA) is the most commonly used material for this purpose. Although, this material is not ideal in every respect, it is the combination of qualities rather than one single desirable property that accounts for its popularity and usage. One of the main drawbacks of this material is considered to be its poor mechanical performance. There have been several attempts in the recent past to address the problem of inferior mechanical properties of these materials. Generally, there are three ways which have been investigated to improve the mechanical properties of denture bases; search for or development of an alternative material to PMMA; chemical modification of PMMA; and the reinforcement of PMMA. Present article is a review of types of fibres reinforced in denture prosthesis and their effects on mechanical properties of denture prosthesis.

The selection of an appropriate luting agent influences the long-term clinical success of fixed prosthodontic restorations. There are varieties of luting agents available from conventional water-based to contemporary adhesive resin cements. However, no single luting agent is capable of meeting all the stringent requirements. Introduction of adhesive resin systems has completely changed the face of fixed prosthodontic practice leading to an increased use of bonded all-ceramic crowns and resin-retained fixed partial dentures. This review aims at presenting an overview of current cements and discusses physical properties, biocompatibility and other properties that make particular cement the preferred choice depending on the clinical indication.[75] Sidhu SK, Sheriif M, Watson TF, The effects of maturity and dehydration shrinkage on resin-modified glass-ionomer restorations,
