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.

Osseointegration in clinical dentistry depends on an understanding of the Healing & reparative capacities of hard and soft tissues. Its objective is a predictable Tissue response to the placement of tooth root analogues. Such a response must be a highly differentiated one and one that becomes organized according to functional demands. The notion of permanently anchoring a prosthesis into the bone through the skin or the mucosa has fascinated clinical researchers over the years.

Planning and executing the restorative rehabilitation of a decimated occlusion is probably one of the most intellectually and technically demanding tasks facing a restorative dentist.The term "occlusal rehabilitation has been defined as the restoration of the functional integrity of the dental arches by the use of inlays, crowns, bridges and partial dentures". Occlusal rehabilitation, therefore, involves restoring the dentate or a partially dentate mouth. The aim is to provide an orderly pattern of occlusal contact and articulation that will optimize oral function, occlusal stability, and...

Speech is a very sophisticated autonomous and unconscious activity. Speech in matured man in a learned habitual neuromuscular pattern which makes use of anatomical structures designed primarily for respiration and deglutition. Because oro-dental morphological features also may influence an individual speech, the dentist should, therefore, recognize the possible role of prosthetic treatment on speech activity.

Edentulousness is on the decline, but it will increase dramatically in the adult population older than 55 years. Throughout the history of dentistry, clinicians and patient's have struggled with options for replacing missing teeth. Treatment options have evolved from acrylic dentures to metal framework, removable partial dentures to fixed partial dentures. Recently, titanium implants have joined the armamentarium of mainstream treatment in dentistry. The development of endosseous osseointegrated dental implants are the nearest equivalent replacement to the natural tooth and are therefore a...

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...

The mouth is the most potent factor in making or marring the beauty and character of face and form. The word 'esthetics' comes from the Greek word 'aistheticos', meaning of 'sense perception'. "Esthetics is a branch of philosophy dealing with beauty and beautiful, especially with judgment of taste concerning them". Esthetics has become increasingly important in the practice of modern dentistry and is synonymous with a natural, harmonious appearance. It influences to a large extent the social acceptance and well being of the individual. A more esthetically pleasing face generally is more...
