What acronym should you follow for SBI readings?
One tooth is missing, how many reading points is there? Do you count papilla 4 and 5?
Yes count IDP 4 and 5. There is 28, you want to count the interdental papilla present.
2 tooth are missing. How many reading points are there? Do you read interdental papilla 4,5 and 6?
27 reading points.
You would read 4 and 6. Bc 2 teeth missing there is no interdental papilla between.
So 2 tooth loss= 1 loss reading point
3 tooth are missing. How many reading points are there? Do you count 3,4,5,6?
26 reading points
lose 3 teeth next to each other = lose 2 ID papilla
do not include 4 and 5, its empty space, no teeth are there
1 tooth is missing due to otho exo. Space is closed, do you read it as missing tooth? How many reading points is there?
27, yes count it as if a missing tooth
This has a reading point of 24, why were the implant readings included 5,4,3?
only in the event of 2 missing teeth do you lose a reading point. here implants are still counted as teeth. so one missing= still inter dental papilla of both neighboring tooth needed.
