Expansion protocols: Important: Functional appliances:

Optimal timing depends on the skeletal maturation of each individual, which can be accurately determined by using the CVM method of Baccetti.  Protocol when treating a growing patient with Class II How Does it Work? MA Protocol Pre‐MA Phase (Light Blue Colour) Purpose: Clinical treatment:…

Work on the arch shape Do not expand too much (no more than 4-5 mm and always with sequential expansion) and work with posterior torque control. First derotate molars, the everything expand. Check that there is always a lateral OJ of at least 2 mm...

Do not exceed 0,1 mm of extrusion per aligner (this will reduce the misalignment per stage)

Best place to insert TAD’s in maxilla is ” T-zone” Recommended implant size in “T-Zone” is 2×9 Beneslider Beneslider distalizer – moves 0.6 mm per month

Notes for Tech (using mini-screws for intrusion):

Distalization protocol: Distalization protocol 2: When starting distalization of premolars posterior anchorage should be reinforced. Ask for 5 to 10 degrees of distal crown tipping on molars while distalizing premolars. Upper arch development: Parabolic arch-shape Staging: Leveling the curve of Spee: Lower arch development:

Consider the position of the tooth root as it is easier to rotate a tooth that is normally inclined. For example, a tooth that is mesially tipped should be uprighted first before attempts to correct its rotation. Collisions Ask Tech: “While aligning, please provide 0.1…

Ptient reference/limits OUTCOMES STRATEGY Class II Correction “Plan 2.5 mm sequential distalization of 50% pattern on the upper arch. Crossbite correction Make 1 mm of upper expansion by buccal crown inclination without exceeding 0-degree torque. Solve the rest of the transverse problem by lower compression….
