The concept of the shortened dental arch was first raised as a concept 30 years ago, with the WHO endorsing a functional dentition of 20 functional teeth without resorting to a prosthesis. This large cross-sectional study from Brazil suggests that having a shortened dental arch does not have any significant impact on oral health related quality of life.

The shortened dental arch (SDA) consisting of ten pairs of occluding anterior and premolar teeth is considered sufficient to provide good oral function. The WHO goal for developing countries of 20 functional, aesthetic natural teeth without resorting to a prosthesis is consistent with the SDA.   The aim of this review was compare the functional outcomes [read the full story…]

Study finds no evidence that replacing missing posterior teeth with removable dental prosthesis decreases risk of TMD pain in patients with shortened dental arches

Over the last few days we have been looking at various outcomes from a multicenter trial that compared the outcomes for two different treatment options for the shortened dental arch. The aim of this analysis was to assess the impact of missing posterior support on the risk for temporomandibular disorder (TMD) pain. As outlined previously [read the full story…]

Trial found no difference in oral health quality of life outcomes for two approaches to management of the shortened dental arch

Yesterday we looked at the reported periodontal outcomes from a multicenter trial that compared the outcomes for two different treatment options for the shortened dental arch. Today we are considering the report of the oral health quality of life outcomes (OHRQoL). As outlined previously patients were randomised into two groups; a partial removable dental prosthesis [read the full story…]

Trial found minor deterioration of periodontal status in patients with a partial removable dental prosthesis

The World Health Organisation has stated that the retention, throughout life, of a functional, aesthetic, natural dentition of not less than 20 teeth and not requiring recourse to prostheses should be the treatment goal for oral health. This is consistent with the concept of the shortened dental arch (SDA) with an intact anterior region and [read the full story…]

Restoring the shortened dental arch with partial removable dental prosthesis

The shortened dental arch (SDA) has been defined as having an intact anterior region but a reduced number of occluding pairs of posterior teeth. The World Health Organization has stated that the retention, throughout life, of a functional, aesthetic, natural dentition of not less than 20 teeth and not requiring recourse to prostheses should be [read the full story…]
