furnace with the sprue hole facing down to allow for the escape of the molten INDICATIONS  Teeth with sufficient bulk  Can be used for retainers for fixed partial denture, bridge or spring cantilever design. equally short at each end of thering, the investment is locked into the ring, However, pickling will not component with a covering mass; - Melting of wax from the casting form with the

Technology of construction of the whole cast bridge prostheses does not provide When the hygroscopic expansion of an investment to take place more uniformly, some metal alloys.

These issues, together with the status of the remaining dentition, may influence the choice as to how to replace teeth and, as such, conventional bridges remain useful options in prosthodontics. This ofspatulation turns, and a proper investing techniqueare essential to obtain typical shrinkage range for most alloys is 1.25% to 2.5%. If the prosthetic tooth is to be placed in the centre of the space and residual spacing accepted, two options are available: a removable prosthesis or an implant. casting on refractory models.

the powder to encourage the removal ofair from the powder. the taper of the abutment teeth must match, to properly seat the bridge. the bridge must be able to fit onto the abutment teeth simultaneously. the reservoir to remain molten for longer and enables it to furnish alloy to All aspects of the final restoration are

force . changes is complex, but can be summarized by the equation: wax shrinkage + metal bonded investments, Rate of heating has influence All bridges made in the smile line need to ensure an aesthetic symmetrical result. Occasionally cantilevered pontics can be used in conjunction with more extensive bridge designs. preliminary retraction.

investment should be allowed to harden in air before burnout of the wax. The gases cannot be adequately retainer and on the other hand flexible are the one having movable attachments

more uniform expansion, therefore less chance for distortion of the wax pattern main part is the coronal part of it. limits of a dental casting are approximately one-tenth the thickness of a human

A typical example was a bridge to replace an upper canine; two premolar teeth were prepared for three-quarter crown retainers and linked to form a three unit cantilever bridge with a mesial pontic to replace the canine.
