Residual ridge resorption (RRR) is a major disease entity that results in functional impairment of stomatognathic system. The loss of bone following the extraction of teeth at the sight of edentulous ridge has been characterized as a long term, cumulative and irreversible process that often proceeds at an alarmingly rapid rate. Proportionally largest amount of bone is lost within the first 6 months and it continues till all the alveolar bone is lost.

Esthetics is defined as "A branch of Philosophy dealing with the nature of and with judgments concerning beauty". For dentistry, the concept of esthetics was narrowed by Scmarer (1978) as esthetics include the morphological aspects only, but Stein (1978) extended it by including cosmetics, e.g. colour related aspects into the science of esthetics. "Esthetics" is defined as being a derivative of the Greek word 'aisthetikos', meaning 'perceptive'1. It pertains to the sense of the beautiful or the science, which deduces from nature and taste the rules and principles of art.

The clinical success and longevity of endosteal dental implants as load-bearing abutments are controlled largely by the mechanical setting in which they function. The treatment plan is responsible for the design, number and position of the implants. After achievement of rigid fixation, proper crestal bone contour, gingival health, mechanical stress, and/or strain beyond the physical limits of hard tissues have been suggested as the primary cause of initial bone loss around implants. After successful surgical and prosthetic rehabilitation with a passive prosthesis, such noxious stresses and...
