Top 10 Questions for Orthodontic Laboratory Technician (Orthodontic Lab Technician) Interview

1. Please explain orthodontic bonding and its procedure.

• Orthodontic bonding is the process of attaching orthodontic appliances, such as braces, to the teeth.
• The procedure begins with cleaning the teeth and drying them to remove any saliva or debris.
• An etching gel is then applied to the enamel of the teeth to create a slightly roughened surface, which helps the bonding agent to adhere.
• The bonding agent is then applied to the teeth and the orthodontic appliance is placed in position.
• A curing light is used to harden the bonding agent and secure the appliance to the teeth.

2. Describe the fabrication of an orthodontic appliance using a vacuum former.

Model Preparation

• Trim and clean the model
• Apply separating medium

Vacuum Forming

• Select appropriate thermoplastic material sheet
• Heat the plastic sheet to its forming temperature
• Place the plastic sheet over the model and apply vacuum pressure
• Trim the formed appliance and remove any excess material

Finishing

• Polish the appliance
• Make any necessary adjustments

3. What are the key factors to consider when designing an orthodontic retainer?
