7. Rinse the casting in distilled or deionized water and shake off the excess water. 8. Place the casting in 3 % hydrogen peroxide (HzOz) for 60 to 90 seconds. This will produce a light gray color (t,in oxide) after drying. 9. Rinse again in distilled or deionized water. 10. Dry with oil-free air or allow to bench dry for 5 minutes. Do not touch, rub, or contaminate the oxide surfaces. 11. The restoration is now ready to use. Silane (Jeneric Pentron, Inc., Wallingford, Conn.) bridging agent can now be applied to achieve a maximum attachment. Follow the manufacturer’s recommendations for silane application. 12. Cement the veneer with a resin cement according to manufacturer’s instructions.

With complete denture trial base, there are often difficulties in securing a stable relationship of the mandibular base to the supporting tissues while obtaining jaw records are. It is customary to seat the trial mandibular prosthesis with digital pressure over the premolar regions just before encouraging the patient to relax the surrounding muscula-
ture and close into the retruded mandibular position. The recording medium often necessitates moving one’s fingers to the buccal aspects of the mandibular prosthesis. In the presence of prominent buccal flanges this poses no problem. In the absence of such buccal flanges (Fig l), the addition of buccal wings, which act as finger rests, may considerably facilitate making jaw records.

The jaw-recording medium of choice may now be placed on the posterior occlusal surfaces of the mandibular prosthesis. The prosthesis is seated with the index fingers on the compound finger rests and the patient is encouraged to close into centric relation (Fig. 3). The finger rests are useful where there has been considerable ridge resorption. The technique is also used at the insertion of the processed prosthesis when centric relation is recorded and for remounting the dentures on an articulator. In the presence of a small mouth with a tight lower lip, it is essential to remove the fingers immediately before tooth contact because any stretching of the lower lip may result in posterior displacement of the mandibular base.
