I have my stuff up for sale in the classified section. For those who are confused about practicing and thinking to shell out money... Consider buying a home set up instead, look up YouTube videos and know the measurements they require... That's all you need... Of course, tons and tons of practice in mounted position. I have UTECH silent compressor (550 dollars), Columbia typhodont, extra teeth, mount... ( I have the Kilgore typhodont too but then many teeth are missing and I really don't want to sell it at full price so if you buy the rest of the stuff I will sell it for 1/4th the price .. And you can buy the teeth yourself. This offer is only if you buy the compressor coz I can't ship just the typhodont as it will cost me more!)
Of course I shelled out money and took a course coz I thought I was doing something wrong but trust yourself and practice like hell. Your work needs to be clean, neat without nicks to adjacent tooth. They look at the finesse in your work along with the measurements. The best thing is either to show your work to some students/ practicing dentists for critique or get some model teeth and your goal is for perfection. No use spending thousands of dollars taking a course... You anyway need to practice! This is the time... You have good 2 months till September ( which I guess is the time all interviews roll in)
Don't forget to brush up on interview skills... Practice, practice and practice speaking. Be confident and everything will fall in place!
