Jensen’s Virtual Study Clubs are geographically defined and meet online every other week on the same day and same time for one hour in duration. Each Club consists of a series of modules that are eligible for on CE credit per hour/module.
Module 1:
Casting Proficiency Skills: Burnout Casting and Torch Adjustment Temperatures
Terry McQuiston- 1 CDT Credit
This Webinar will cover the effects on casting, cooling, density, and oxide development on dental alloys due to temperatures used in the burnout of the investment and melting of the alloy. There is a specific relationship between what the proper burnout temperature should be and the differential of what temperature the alloy is cast. Altering this relationship can result in porosity, burnt alloy, or short castings. Torch adjustment and casting machine temperatures will also be covered as they pertain to a proper melt.
This Webinar will highlight to the technician the right amount of alloy with no wastage while being able to use the correct amount of fresh alloy, sprue it correctly to feed it in the most efficient manner possible and then burn it out and cast at the correct temperatures to ensure proper fit, marginal integrity, and the densest possible frameworks.
Module 2:
Alloy: A Technical Focus - Palladium Alloys
Terry McQuiston- 1 CDT Credit
Palladium Alloys, how do you know which to choose? In this Webinar, we will discuss the differences between the types of Palladium Alloys and why and when to use them. Most laboratories know that they use Palladium Alloys when the price of Gold gets too high. Most laboratories also know that some Palladium Alloys might have heavy oxides while others contain significant Silver content. There is so much more to know about Palladium Alloys. We will review the properties of Palladium Alloys so that you make the appropriate selection for your laboratory with confidence. We will also discuss how to properly cast and solder Palladium Alloys along with proper oxidation and how oxides will affect porcelain shades.
Module 3:
Alloy: A Technical - PFM Framework Design
Terry McQuiston- 1 CDT Credit
This Webinar will cover framework design for singles, splints and bridges for PFM alloys. We will also discuss metal occlusals, partial rests, occlusal stops, guide planes and contouring of substructures to facilitate esthetic reconstruction because of loss of dentition and/or improper implant placement.
Module 4:
Alloy: A Technical -
Soldering Techniques and Troubleshooting
Terry McQuiston- 1 CDT Credit
Not everyone has a laser welder. Even if you do have one, there are many times we just "tack" a splint or bridge and then solder it. Pre-soldering is a technique that can be easily mastered if done correctly or produces dire consequences if done incorrectly. A complete review of pre-soldering techniques along with fixing holes in copings and repairing margins will be explained in detail.
Post-soldering is mainly proper technique and fabricating the framework correctly to be post-soldered. The common theme here for any soldering is "following proper technique". This Webinar will cover the proper techniques and illustrate what can happen if proper techniques are not followed. Questions are encouraged and any pictures that can be sent in prior to the Webinar are welcomed and appreciated
Module 5:
Alloy: A Technical Focus -
Metal Finishing, Oxidation and Bond Strength of Opaque
Terry McQuiston- 1 CDT Credit
The porcelain-fused-to-metal restoration has proven to be the most prescribed and highly successful restoration available. Its beauty is not in esthetics alone, but in the way the way the alloy substructure can be cast to fit just about any preparation available.
Beyond the substructure design and CTE matching of alloy and porcelain, what will ultimately determine longevity of the restoration is how well the opaque bonds to the alloy surface.
In this Webinar, we will discuss metal finishing, oxidation of various alloys, opaque application technique, and firing. We will also discuss how this all relates to the bond strength of the opaque layer to the alloy surface. Whether paste, powder, or sprayed it is of ultimate importance to PFM and PTM restorations.
Module 6:
Alloy: A Technical Focus - When Good Metal Goes Bad
Terry McQuiston- 1 CDT Credit
This Webinar discusses common alloy related maladies that can occur in the laboratory and how to diagnose them. Topics will include a variety of casting problems that we commonly see such as fit, spruing, porosities and tears. We will also review porcelain problems that can develop from alloy related issues such as bubbling, bonding and discoloration. Soldering issues will also be discussed as they pertain to alloy handling. This is a great Webinar on troubleshooting alloy related difficulties.
