A couple of cases / New Camera attachment

[droberts]

Here is a couple of cases, one finished and the other in the wax set-up stage.
Bought the Close-up diffuser lens package from PhotoMed for my Cannon G12. Had to make some lighting changes, as in position of lights on to the prosthesis. The main advantage is, for real close up shots. The camera is now positioned approx. 6 inches away from the prosthesis allowing room for the light. Any tips or comments are welcome.

Man that maxillary labial flange is HUGE...love the lower, so clean and smooth on the underside, very pretty work!!!

Looks good. What final polishing compound are you using?

Moldent from Yates/Motloid. As far as I know, most any supply company will have it.

We use the same red highshine its the best I have found.

Nice work Danny, why were you lazy, no opaque on that bar? Just cause you have 15 mm of acrylic doesn't mean you don't need to

The convex nature of the tissue side of that prosthesis is textbook perfect, too many times we have a hard time getting patient to like it with out ridge-lapping.

I use the red Moldent. Yours just looks extra shiny! Are you using the diamond D (looks like it might also be the 199)?

Geeesh, John. I'm concentrating on taking photos with my new toy, and your picking on me. Dont make me have to come over there! Ha I did that on purpose, not opaquing the bar. I knew it would not show through the facial, and with adding tissue tint on the bottom as I normally do, it would blend in. I am hoping to get the photos back soon from the doc to present them on here. I do not ridge lap on the mand. unless I absolutely have to. Hope all is going well, take care

Its ivocap for sure, looks like "Preference implant"

Ivocap (Light) with added tissue tint before injecting. A hint, especially on bar hybrid cases as such. The smoother the wax, the less polishing you have to get the burr marks out. I only use a rubber wheel for touching up the acrylic.

That looks great! I always have trouble getting the tinting to stay put when I use ivocap. Got any tips?

The main thing to start with is, wax the prosthesis to the thickness you want in the final. Otherwise you'll end up grinding it out if you didnt. To proceed with that statement. Make sure the wax has been stippled as in the waxed photo above. I apply the tissue tint around the teeth using the shades I prefer, and also build it up slightly to give a depth affect. I also apply it to the impression cast, especially on the labial and buccal borders to let it blend in with the other half of the flask. Do not let it dry out, but avoid over wetting it. Close the flask, place injection capsule (acrylic), injector, and let set for approx. 3-5 minutes. Then apply pressure opening up the lever very s-l-o-w-l-y, to where the needle on the gauge barely moves. Once it is up to full pressure (6 bar), open the lever completely.

Nice job! Weren't you telling me that you use a little different sprue placement on these too. Refresh my memory. Looking forward to my trip to Iowa in a couple weeks. (Honest!! I really am.) The weather can't be any worse than it is here. Brrr!!

Bob,

Appreciate you bringing that up (Spruing). I sprue all cases using 10ga round wax. If they are going to be charcaterized (tissue tint) they are sprued to the tuberosities, not in the middle of the palate. Mand. arches are normal, sprue to the retro-molar pad area. I will on hybrid cases and sometimes on mand. arches, run one extra one up the middle off-set to prevent any movement of my tissue tint. Keep in mind, the more sprues, the longer it takes the acrylic to get to the anterior.

Nice job Danny!

I like your explanation of getting the tint to stay stabile while injecting. I kept going full throttle and will "feather" the pressure lever on my next tint case. Sometimes you just gotta' spell it out for me.

I was even trying to mix auto and heat cure monomers (in various ratios) to come up with a resin that would stay during placement but still cure with heat and the injection resin. I am sure you solved some problems right there for me.

What tint system or materials are you using?

I am using Fricke's Colorhue tints, and Lucitone monomer.
Full throttle will blow it right out as you have experienced. Turn the
level to where the needle on the gauge just creeps up to get to full
6 bars.

I am interested in this technique as well, on the circa 1991 video the ivoclar put out on this system, guy tints then mixes the capsule, takes about half of the acyclic out of the tube and places it in the flask over the tinted buccal, before closing the flask and injecting.

I have done it this way and it works just fine

I will try Danny's method tomorrow.

Still playing with the camera Just finished this partial working on close up shots. Lighting still is a huge factor. Sometimes shows too dark or too light.
Anyway, this case was also characterized with the same process mentioned above.

John, I to have tried the putty method of laying the acrylic over top of the tissue tint. Nothing wrong with it, just prefer to do it this way. You may notice that used acrylic is sometimes not as pliable as fresh. So on my bigger cases involving implants etc. I will mix fresh for all. And not to ever use acrylic that has been through the processing more than twice.

 

[JohnWilson]

Glad your having fun with the camera, I had it on my list of resolutions last year and sadly I did not master it. The bad thing by the time I get things dialed in it will be obsolete

I truly believe that once you start to photograph your work it will take you as a tech to the next level, It shows so much that our eyes never really focus on, Every little imperfection is magnified and it makes you pay closer attention to the little things.

As for reusing acrylic, I have yet to do that, I guess I waste a ton as I never re inject previously injected resin.

 

[Smilestyler]

I'm not familiar with your camera set up, but I use a macro lens with a ring flash and lighting is never an issue. If you are trying to achieve something unique with lighting the guy at the camera shop suggested to me how some photographers will pivot there flashes to bounce off of ceilings or walls to manipulate lighting. I don't know if this will help you.
