Descrizione
Online practice on aligners and indirect bonding transfer tray manufacturing using 3D Shape Ortho Analyzer!
– During the THEORY and PRACTICE you will improve the following skills:
– Work with digital study models
– File management
– Indirect bonding transfer tray modeling and manufacturing
– Aligner modeling
– Attachment modeling.
The instructor is Stefano Negrini - dental technician-pioneer in the use of digital technologies in orthodontics.
Lezione 1.Indirect bonding transfer tray. Part I
– Introduction to digital technologies
– Bracket placement on the maxilla and the mandible manually and automatically
– The principles of creating an occlusal plane
– Correction of the rotation center
– The recreation of separate teeth and gingiva manually
– Failure and mistakes prevention when working in 3Shape
– Arch shape placement
– Bracket movement: control, changing of the position and torque
– Ways to combine brackets from different libraries
– Managing the position of the tooth and bracket
– Identifying the correct bracket position in relation to the ginigva and detecting the premature contact between brackets and antagonist teeth
– Plan validation
Lezione 2.Indirect bonding transfer tray. Part II
– The principles of communication between the doctor and the lab
– Creating bracket transfer master model
– Working with virtual articulator
– Cheking the occlusion and workflow settings
– Control of the vertical dimension to avoid inter-occlusal interference
– Cutting the model and getting the text on the model
– Composite to relise a model
– Materials for printing the model
– Printing machines for the lab.
Lezione 3.Aligner treatment
– Aligner treatment planning: important information for the lab
– Biomechanics of teeth movement: rotation, angulation, inclination
– Dental arch analysis
– Brackets and aligners: the difference in mechanics
– Expantion vs distalization by aligners
– Crowding and aligners: tactics in simple, moderate and advanced cases
– Managing the timeline
– Correction of occlusal and interproximal contacts: notes for doctors
– Overbite and overjet control
– Lingual attachments.
Lezione 4.Aligner modeling
– Midline misalignment: tactics
– Movement limitation when using aligners:
- inclination - angulation
- rotation
- torque
- distalization - mezialization
- intrusion - extrusion.
– "Screwdriver" effect
– Management of different attachments:
- The best positioning on the tooth
- Different shapes for different movements.
– Prevention of the wrong effect
– Transfer tray for attachments
– Calculating the number of aligners
– Model set comparison: control of the changing.
