Precision attachments can be used in removable prosthodontics to improve the retention, stability and aesthetics of a prosthesis. Their use is not commonplace. However, when used appropriately, it is possible to construct a more satisfactory prosthesis where conventional partial dentures have previously been unsuccessful. The first of two articles will describe the different types of precision attachments, including intracoronal, extracoronal and radicular. Their relative indications, advantages and disadvantages will also be discussed.
Clinical Relevance: Precision attachments are an option to increase retention in challenging prosthetic cases.
Article
A significant proportion of the United Kingdom is partially edentulous.1 Since the inception of the Adult Dental Health Survey in 1978 the UK has shown a decline in the number of edentulous people. The mean number of teeth observed in the adult population increased from 23 in 1978 to 24.8 in 1998. Between 1988 and 2009, very few adults are reported to have become edentate. In this regard, in 2009, 94% of the combined populations of England, Wales and Northern Ireland were dentate (had at least 1 natural tooth). In 2009, the overall mean number of teeth among dentate adults was 25.7.1 Whilst conventional fixed prostheses and dental implants may be indicated for restoring these edentulous spaces; the removable partial denture is still a commonly prescribed treatment option for patients in the UK. In certain circumstances, optimizing retention, support and stability, with or without compromising aesthetics, is difficult. This can relate to the number of teeth remaining, their distribution and angulations and their restorative status. Precision attachments may improve success if used appropriately.
