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
LINGUAL BAR WITH CONTINUOUS BAR INDIRECT RETAINER
SYNONYMS: KENNEDY BAR, SPLIT LINGUAL BAR, DOUBLE LINGUAL BAR
1. Situations where the major connector must contact the natural teeth to provide bracing and indirect retention and there are open cervical embrasures which contraindicate the use of a lingual plate. There must be adequate space for the lingual bar portion of the major connector. Continue reading
The MAJOR CONNECTOR is that part of a remvable partial denture (RPD) that joins the component parts on one side of the arch to those on the opposite side. It is the unit of the RPD to which all other parts are directly or indirectly attached. Continue reading
The first requirement of a major connector is rigidity. This allows stresses that are applied to the partial denture to be distributed effectively over the entire supporting area, including the teeth, underlying, bone and soft tissue. Other components of a partial prosthesis can only be effective if the major connector is rigid. Flexibility allows forces to be concentrated on individual teeth or edentulous ridges causing damage to those areas. Continue reading

Denture base extension:
The lower trial denture extension should be tested with the patient mouth is opened no more than half opened position. To allow the surrounding musculature is in an acceptable state of relaxation.
• Labial and buccal extensions are checked as for the upper trial denture. Continue reading
Denture base extension:
a) The labial and buccal extension:
- If marked overextension of the flanges, will stretch the sulcus tissues when denture inserted, leading to elastic recoil result in dislodgment of the denture, immediate denture displacement after its seating.
Preliminary insertion of complete denture wax up (trial denture) to determine the fit, esthetics, maxillomandibular relations —–etc.
Space Maintainer is a fixed or removable appliance designed to preserve the space created by the premature loss of a tooth (can be primary or permanent tooth). Fixed Space Maintainer is not intended to be removed by the patient whereas Removable Space Maintainer is designed for easy removal for cleansing and/or adjustment. Continue reading
