subject: Precision Attachment- an advanced prosthodontic solution [print this page] A precision attachment is a combination of removable denture and porcelain crowns. It is a device used for attaching a fixed or removable partial denture to the crown of an abutment tooth or a restoration. It consists of a female portion within the crown of an abutment and a fitted male portion attached to the denture proper. This kind of combination was from the word precision attachment itself that we are using from PRECI-Vertex from Preci-Line Attachment. It was originally made in Germany. It is a plastic device that inserted into the male part of the denture to make it more situated and precise. This will help to lock the denture from the crown.
Laboratory Procedure:
From the impression given by the dentist, the technician will pour a castone and make a die model, die opening and articulating then it will go straight to wax-up department. While fabricating the wax for the crown the male part will be attached vertically both side of the free end. It must be parallel same like the telescopic denture.
Once it is done it will be invested, make the muffle hard put inside the oven and ready for casting at a certain point of time. After the casting, technician will divest the muffle and start grinding the metal and make the crown. Most of the European laboratory preferred to make the metal try-in and pick-up impression especially when it is long expand to make sure that the fitting is good and to prevent any upcoming problems. In making the female part, in male part technician will put pattern resin to make mold for female part then framework attached on it. This will be use to connect the secondary crown and support the acrylic teeth to replace the missing teeth. A partial denture of the invention can move only in one direction exhibiting a vertical upward-downward movement of its free end and there relieving from stresses applied onto the supporting teeth.
