Why the other options are wrong:

• Because follow-up visits are less frequent.: Follow-up visit frequency is not given as a reason.
• Because lab production times are unpredictable.: Lab production times are not described as unpredictable.
• Because aligners are less effective for crowding.: The orthodontist says aligners can handle crowding, so effectiveness is not the issue.

Correct Answer: They involve additional lab fees and extra refinements.

Why this is correct: The orthodontist says aligners cost about $7,400 compared to $6,200 for braces, and the higher price is because of lab fees and extra refinements. These additional costs make aligners more expensive.

Why the other options are wrong:

• They require more frequent office visits.: More frequent office visits are not the stated reason.
• They use a more expensive type of material.: Material cost is not mentioned as the cause.
• They include a built-in retainer at the end.: A built-in retainer is not described as part of the aligner package.

Correct Answer: The need for precise control of tooth rotations.

Why this is correct: The orthodontist says braces give more precise control, especially for rotations. Emma has moderate crowding and a slight overbite. The need for exact tooth rotation is the dental factor that favours braces.

Why the other options are wrong:

• Severe jaw misalignment.: Severe jaw misalignment is not mentioned.
• A high risk of gum disease.: A high risk of gum disease is not discussed.
• Damage caused by previous retainers.: Damage from previous retainers is not a factor in the recommendation.

Correct Answer: His daughter's habit of losing dental devices.

Why this is correct: The father says Emma has already lost two retainers. The orthodontist calls this a red flag for aligners because lost trays delay progress and add replacement fees. Her history of losing devices directly shapes the recommendation.

Why the other options are wrong:

• His daughter's fear of dental pain.: Fear of dental pain is not discussed.
• His daughter's busy school schedule.: A busy school schedule is not raised as a concern.
• His daughter's preference for ceramic brackets.: Ceramic brackets are suggested by the orthodontist, not requested by the father.

Correct Answer: Coverage usually depends on the individual insurance plan.

Why this is correct: The orthodontist says Saskatchewan Blue Cross typically covers a percentage up to a lifetime maximum, regardless of the method. However, the family needs to confirm their specific plan. Coverage depends on individual insurance details.

Why the other options are wrong:

• Only braces are eligible for insurance reimbursement.: The orthodontist says coverage typically applies regardless of method, subject to confirmation of the individual plan. It is not described as limited to braces.
• Aligners are never covered by Saskatchewan Blue Cross.: The orthodontist says Saskatchewan Blue Cross typically covers a percentage regardless of method, but the family must confirm the specific plan. This does not support saying aligners are never covered.
• Insurance covers the full cost up to age sixteen.: Full coverage up to age sixteen is not mentioned.

Correct Answer: They will review the information before booking records.

Why this is correct: The orthodontist tells the father to take the information home, and they can book records when he is ready. The family will review everything before making a final commitment.

Why the other options are wrong:

• They will wait until Emma finishes volleyball season.: Waiting for volleyball season to end is not discussed.
• They will immediately schedule the installation of aligners.: They are leaning toward braces, not aligners.
• They will seek a second opinion in Regina.: Seeking a second opinion in Regina is not mentioned.
