How to Use This Calculator
  1. Enter the total teeth present and number with hopeless or questionable prognosis.
  2. Input average clinical attachment loss (CAL in mm) across all teeth.
  3. Set the number of strategic abutment teeth available for prosthetic support.
  4. Review Remaining Functional Teeth, Prosthetic Options, and treatment complexity score.
  5. Use these findings to develop an integrated perio-prosthetic treatment plan with your patient.

What each input means

Teeth present
Total number of remaining teeth.
Hopeless prognosis teeth
Teeth with hopeless periodontal prognosis.
Questionable prognosis teeth
Teeth with questionable prognosis that may respond to treatment.
Average CAL (mm)
Average clinical attachment loss across all teeth.

What each result means

Prosthetic option (1-4)
1=fixed, 2=RPD, 3=overdenture, 4=complete denture.
Good prognosis teeth
Number of teeth with good periodontal prognosis.
Available abutments
Effective number of teeth for prosthetic support.
Treatment phases
Number of treatment phases required.
Total treatment time (months)
Estimated total treatment duration.
Complexity score (1-5)
Overall case complexity rating.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Teeth present = 20, Hopeless prognosis teeth = 3, Questionable prognosis teeth = 4, Average CAL (mm) = 4 = 4 input(s) provided
  2. Calculate Prosthetic option
    1 = 1
  3. Calculate Good prognosis teeth
    Good prognosis teeth
    13 = 13
  4. Calculate Available abutments
    Available abutments
    15 = 15
