During the lifetime a large number of changes tend to occur that affect teeth and oral cavity. Tooth loss is a change that has a diverse etiologic basis: dental caries, trauma, periodontal disease, etc. It affects other teeth (neighbouring and antagonistic), soft facial tissue, tongue, yet also aesthetic, phonetic, and psychosocial function of teeth in oral cavity. Shortened dental arch is where toothless areas are placed on one or both sides of the dental arch, behind the natural remaining teeth. According to Kennedy classification, bilateral shortened dental arch represents Class I, whilst unilateral shortened dental arch represents Class II. Upon advancements in dentistry, there is a broad range of treatment options concerning these varieties of partial edentulism. One of them is a removable partial prosthesis with clasps made out of cobalt chrome alloy that both compromises the tooth and lacksin aesthetics. Another possibility is combined prosthetics that consist of a removable part (a partial denture that can be removed from the mouth) and a fixed part (e.g., telescopic crowns or dental implants). They provide superior aesthetics and also better periodontal health of the anchoring teeth. In the 1980's, a number of studies were published representing a new concept, the so-called “shortened dental arch concept” that is based on the absence of intervention, or the absence of compensation for lost teeth. The goal of dental treatment is to keep as many natural teeth as possible, especially in the lateral area of the oral cavity to maintain adequate chewing function and hence a good quality of life of an individual.
