(i.e. Custom trays)•This will allow you to be much more efficient and comfortable with that days appointment.Cubical Set Up•Obtain from dispensing the appropriate kit for that days treatment.•Hook up everything that may be needed. (i.e. High and low speed suctions, air water syringe, and the hand pieces.)•Lay out the instruments needed, gauzes, cotton rolls, floss, etc. Remember that the instruments were designed with a purpose in mind. (i.e. The articulating paper holder.)•Do not take things out as you need them. This will only slow the treatment and give the patient the idea that the operator does not know what they are doing.Diagnostic Casts•Purpose:•Evaluate a patient’s occlusal scheme.»i.e. Occlusal plane or premature contacts.•Evaluate the alignment of the teeth.•Visually present to the patient treatment that may be needed.•Custom tray fabrication.Diagnostic Casts•Importance is often underestimated and therefore not done properly.•Need full extensions to cover all necessary anatomical landmarks.•i.e. Hamular notches, retromolar pads, depth and shape of the vestibule, lingual flange and floor of the mouth.•This allows for the proper custom tray fabrication.•Cast trimming should provide a land area around the entire cast.Common Mistakes With Diagnostic Casts•Under extension of impression material.•Over trimming of the casts.•Use of the “dog dish” to form the base.•Not large enough to support or extend to the all anatomical land marks.»i.e. Hamular notches, retromolar pads, and the full vestibule.Custom Trays Crown and Bridge vs. Complete DenturesCrown and Bridge Custom Tray•Place the appropriate wax relief.•Allows for proper flow and uniform thickness of the impression material.•Tray stops on 3 to 4 teeth.•Place stops on nonfunctional cusps.•Keeps the tray stable.•Prevents over seating of the tray.•Tray extensions.•Extends at least 4-6mm beyond the free gingival margin.•“U” or horseshoe shaped.•Displaces the cheek and tongue away from the margins.•Allows the heavy body impression material in the tray to force the light body impression material down into the sulcus of the retracted tissue.Edentulous Custom Trays•Primary impression should include all the anatomical land marks.•i.e. Tuberosities, hamular notches, retromolar pads, the full vestibule, floor of the mouth, and the lingual flange.•Tray fabrication procedure.•Block out the undercuts, but not excessively.•Vaseline (lubricate) the cast.•Place one layer of base plate wax relief.»Mx: cover the ridge, rugae, and the midline.»Mn: cover the ridge, and the retromolar pads.•Vaseline the top of the relief wax and the cast.»The relief wax remains in the tray throughout the border molding procedure. The wax stabilizes the tray and provides room for the impression material to flow uniformly.Adjusting the Edentulous Custom Tray Intraorally•Remember, do not remove the relief wax until the border molding is complete.•Prior to border molding the tray must be adjusted.•The tray peripheries are trimmed back approximately 2-3mm short of the vestibular depth.•The tray should not be displaced while manipulating the cheek to shorten the depth of the vestibule as much as reasonably possible.Border Molding With Compound•Set up.•Properly adjusted tray with the relief wax still in place.•Hot water bath filled to the line inside of the water pan and heated to 140-142 degrees Fahrenheit. •Compound sticks, Bunsen burner, and the Hanau torch.•The compound should be added in quadrants.•Be sure that the tray and compound is dry before adding any compound to the tray.•The Bunsen burner is used to soften the compound so it can be placed on the periphery of the tray.•The Hanau torch uniformly softens the newly placed compound as well as part of the recently placed compound.»This will give the compound the appearance of having been placed all at once. Rather than a bunch of stops and starts.•The compound is then tempered in the water bath to prevent burning the patient’s tissue.Trimming An Edentulous Cast•Maintain a land area of ~6mm wide.•Aids in the flasking and processing of the denture.•Prevents the accidental trimming away of anatomical land areas.•Trim the land area to a height of 3mm short of the vestibular depth.•If too long, undercuts are created which will make it difficult to remove the base plate. •Allows for an accurate vestibular shape during processing.Wax Try In•The teeth are to be set, festooned, and checked off by an instructor prior to the patient’s appointment. •Set the teeth with the appropriate curve of Spee and Wilson.•Important if a balanced occlusion is to be achieved.•Festooning•Clean the wax off the teeth showing the proper amount of tooth.•Bulk the wax for the desired amount of lip support.»Makes a difference how much of the anterior teeth will show.•The patient’s approval is very important.•Vertical dimension of occlusion and jaw relation record re-verification.Base Plates•They are made on the soft tissue areas, therefore are not transferable to different casts of the same arch.Pressure Indicating Paste vs. Disclosing WaxPressure Indicating Paste (PIP)•Used to adjust
