The study objectives were to assess the preferences and trends about fixed restorations in dental practice. Introduction: Different type of restorations is being used is dentistry for partial or fully lost tooth, An artificial tooth is called as pontic, it can be removable or fixed, composed of different type of material according to the need and properties. Dental restorations can be divided according to the material used. Porcelain fused to metal (PFM), Metalo-acrylic, All Ceramic and All Metal restorations. From eighteenth to nineteenth century, dental restorations were developed with the introduction of feldspathic materials. This material was used at anterior region in the form of jacket crowns which lead to the evolution of all 2ceramic restorations. These restorations were excellent in esthetics but weak in strengths. These materials were further developed afterwards. A new system was also introduced in dentistry that uses metal to increase the strength of the porcelain to produce feldspathic ceramic fused to metal copings which accommodate the defects and requirements. PFM restorations have represented the “gold standard” for restorations. They are predictable, easy to fabricate, economical and they help to obtain good prognosis. PFM also have some limitations about esthetics. It reflects excellent clinical results, ease of casting procedures and excellent final results. PFM is good in strength and esthetic when compared to the acrylic resin veneers which were used previously
