all started because of this

Ortho #1: Wanted to remove top two 1st bicuspids and one 1st bicuspid on the bottom and since im missing a molar have a screw put in for a anchor for the braces and wanted $3,500
He wont be able to put brackets on my front teeth into about 7 months into treatment (also this is the only ortho with all x-rays) but is also a dental school
Ortho #2 Wanted 6 month speed treatment and only concern was to close gaps not align jaw or concerned with bite and wanted $3,700
Ortho #3 Similar to ortho #1 except instead of installing a screw will use 1 molar as a anchor for braces also recommended expander
Ortho #4 I thought was best one, looked at my teeth for the longest and wanted to keep all my teeth in and install braces and if it doesn't work out he can always take out the teeth later, wanted to keep all teeth in and have retainer in for 3 years so teeth wont go back to original position, but wanted 5,700
Ortho #5 Not sure on treatment but similar to ortho #4 and wanted to keep teeth in and remove then in future and wanted $4,500
uh btw ortho #4 said that installing a screw is typical for a dental school to do since there still practicing with different treatment but he will use 1st molar since hes not in school any more
Which you guys decide on?
