In dentistry, precision attachments are the functional mechanical parts of the removable partial denture made of plastic, metal or a combination of both. Precision attachment partial dentures can be used to restore arches where there are not enough teeth for fixed bridgework. They consist of two parts referred as the ‘male’ part that is fixed to a crown inside the patient’s mouth and a ‘female’ part which holds the partial denture. The male is machined by the manufacturer to fit the female with such precision that any male out of the box will fit any female with an exact degree of accuracy. All of the precision attachments in a partial denture are positioned so that they are exactly parallel to each other. The patient can insert and remove the partial dentures and the aim of the precision attachment is to give the patient maximum comfort and ease while wearing, inserting or removing. Continue reading
