    CEBA loan repayment Canada

    Just curious how everyone's business is doing now that the CEBA loan repayment is due? I recently paid back the $40,000 owed. The last 3 months of 2023 were very slow for me & had to take a pay cut to fully payoff the loan, but I'll be okay. I know a couple of other labs that were also very slow...

    Bioform porcelain

    Doing some house cleaning at the lab and found some old porcelain. Ducera is probably 20 years old, but I'm not sure how old the Bioform porcelain is. My business partner had it from a long time ago. Maybe 60s or 70s? Anyway, he had a heart attack this week(blot clot in heart artery & is now ok)...

    Full Z crown issue

    I send all of my zirconia work out to be scanned and milled. A full zirconia crown was made, finished and sent to the dentist. During the appointment to insert the crown, the dentist was making some adjustments and he said that a translucent 'coping' detached from the inside of the crown. It was...

    Broken screws on 10 year old case

    10 year old cementable bridge came out in the patient's mouth with two abutments. Dentist asks if we can remove abutments without damaging the porcelain so he can just order 2 new screws and put everything back in the mouth. I put everything in the ultrasonic for 30 minutes and was able to pull...

    Which Emax ingot?

    Stump shade ST7 Crown shade chromascope 6B-420 or 3L1.5 3D Vitapan Dentist wants the incisal 1/3 of tab used for entire crown shade. More translucency and less value. Does the ST7 stump shade match closer to the ND 2 stump shade? I only have LT ingots. Can this be done using a LT D2 ingot...

    Lab screws used in patients mouth.

    Dentist placed screw retained bridge in mouth with 3i Biomet implants. They torqued the lab screws in the patient's mouth instead of the gold screws. The dentist is now worried that the lab screws may break over time or break if any attempt is made to remove them. I personally think that they...

    What to do?

    Last month I did a case involving a pfz crown on top of a zirconia abutment with ti base. It was not cemented until this morning and now I got a call that the porcelain chipped on the incisal edge. 3 hours after the patient left the office. The incisal was thin because the patient insisted on it...

    HO0 emax

    I'm using the HO0 ingot for the first time and the value was way too high. My Rep told me to layer with Bleach 4 dentin and Bleach incisal. That ain't right. I'm supposed to match 2.1 and 2.2 to 1M1 3D Vitapan. Any tips to match this shade? Should I try layering B1 dentin?

    Broken Abutment

    The dentist calls and tells me that an implant abutment from Straumann broke in the patients mouth. The cemented pfm crown with most of the abutment broke off. The patient said that the crown suddenly came out and everything was fine before that happened. I'm thinking the screw must have came...

    CAD/CAM wax

    I send out my zirconia units to be made by other labs and have been dissapointed at some of the coping designs that I received. I began waxing my copings to be copied as close as possible in zirconia and have been pleased with the results. I just received and used a CAD/CAM wax by Yeti Dental...

    Loose screw retained implant crown

    I just got a call from the dentist about a case we did last October. It's a screw retained implant crown that suddenly got loose in the mouth about a month ago. The dentist said he torqued it in the mouth correctly & this shouldn't have happened. He's sending the case back to me so I can look...

    Abutment analyzer?

    I'm not sure of the correct name, but I've been told it may be abutment analyzer or putty analyzer. You're supposed to place it in the implant coping until it hardens making a copy of the implant abutment. The doctor uses this to remove excess cement, leaving the perfect amount of cement inside...

    What is this?

    I got this drawing from the Doctor to try and find out what implant this is. The patient had this implant placed in Italy about 12 years ago and had no other work on it. There is just a cover on it. There are two circular holes in this implant going right through from one side to the other. Any...

    Some advice on this case.

    The five anterior teeth on the maxillary will probably be prepared for a 5 unit splinted pfm. The doctor wants to attach a denture to the 5 unit splinted pfm (with a lingual ledge on the teeth) . He wants attachments that can easily be replaced if needed. I was thinking ERA attachments for this...

    Have you ever made...

    ... a full zirconia crown? Let's say there's a molar with very little room, but the patient doesn't want a full metal crown, would you or have you made one in zirconia? Also, would you make a zirconia coping with zirconia margins (like a pfm with metal margins)? I'm just curious.
