How to Use This Calculator
  1. Enter the starting wire size/material and target final wire size for the case.
  2. Enter planned treatment phases (leveling, space closure, finishing) and bracket slot size.
  3. Read recommended wire sequence progression and estimated months per wire.
  4. Review cumulative treatment duration from first wire to final finishing wire.
  5. Adjust sequence based on individual patient response and case complexity at each appointment.

What each input means

Crowding (mm)
Total arch crowding in millimeters.
Bracket System
0 = Self-ligating (Damon, Speed), 1 = Conventional twin brackets.
Patient Age
Patient age affects wire change intervals.
Extraction Case
0 = Non-extraction, 1 = Extraction case (adds space-closure wire).
Arch Treated
0 = Both arches, 1 = Upper only, 2 = Lower only.

What each result means

Total Wire Changes
Total number of arch wires in the sequence.
Total Wire Time (months)
Estimated total time across all wires.
Initial Alignment (months)
Time in initial NiTi alignment wires.
Working Phase (months)
Time in rectangular working wires including space closure.
Finishing Phase (months)
Time in stainless steel finishing wires.
Crowding Factor
Multiplier applied to alignment phases based on crowding severity.
Age Factor
Duration multiplier based on patient age.

How this is calculated

Worked example, using the default values

  1. Identify Input Parameters
    4 parameters
    Crowding (mm) = 4, Bracket System = 0, Patient Age = 14, Extraction Case = 0 = 5 input(s) provided
  2. Calculate Total Wire Changes
    Total Wire Changes
    6 = 6
  3. Calculate Total Wire Time
    Total Wire Time
    11.4 = 11.4
  4. Calculate Initial Alignment
    Initial Alignment
    3 = 3
