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

THE DE-EPITHELlALlZED CONNECTIVE TISSUE PEDICLE GRAFT (Roll Technique)
Basically, it is a form of contiguous grafting (pedicle graft} which utilizes as the donor site only the connective tissue of the palate adjacent to the ridge. The epithelium over the pedicle is first removed. This is readily done, using a non-epinephrine bearing anesthetic, by sharp dissection or by use of a rotary diamond instrument. Free bleeding, permitted by the non-epinephrine anesthetic, is evidence of complete epithelial removal. The tissue is then infiltrated with an anesthetic containing a hemostatic agent, and a connective tissue pedicle flap is outlined through to the osseous, and then elevated from the palate within the de-epithelialized zone. In this procedure, it is important that the proximal marginal tissue of the adjacent abutment teeth is not involved. This will ensure stability of the crown margin to tissue relationship.

What Is the Difference in a Dental Bridge and a Removable Partial Denture?
When a tooth or multiple teeth are missing, there are a few options for the patient to replace it/them. Two of the most common choices are either by fabricating a bridge, or a removable partial denture (RPD). These two are different in terms of aesthetic and functional aspects, and hence, they have their own indications, as well as advantages and disadvantages. Continue reading
