Cobalt Chrome castings

Clasp assembly detail from ring skeleton

Our team has a wide and varied range of experience in castings and prosthetics. Enhanced by attendance at various courses, this enables Creative Chrome to offer an extensive range of bespoke cobalt chromium castings, primarily for dental applications.

As well as the usual selection of partial designs, the laboratory can also undertake a variety of combination work with attachments and implant bars, sectional dentures and swing-locks. We also manufacture Maryland and Rochette bridge frames in nickel chrome alloy.

Close attention to fine detail is an essential requirement in producing a delicate yet durable casting, and great care is taken at each stage of the fabrication process. The quality of the materials is of paramount importance and a great deal of care goes into their selection and use. We have adopted Alexium 21® from M. D. Alloys as our Cobalt Chromium alloy due to its excellent properties, and now use it for all of our chrome cobalt castings. Careful forward planning and strict work protocols ensure that each finished casting reaches the high functional and aesthetic standards of the laboratory.

Double Arm Swing-lock

Figure 1: class 3 jaw relationship, left-hand side

This case was first presented to Steve in 1993. The patient has a class 3 bite, as seen in figs 1,2 and 3, and wanted a denture made to present a class 1 appearance. Previous attempts had failed because the anterior teeth needed to be set so far forward of the ridge that they destabilised the whole appliance even with clasps. The challenge was to manufacture an upper denture that would be at once cosmetically pleasing, retentive and stable.
