Finishing Treatment & Retainers - FAQs

Can a patient use the last aligner as a retainer?

Retainers are designed for the retention phase based on the final step of treatment, while aligners are specifically made to achieve tooth movement. The treating physician should decide when the retention phase starts and what type of retainer or retention protocol is most suitable for the patient.

 

When is the best time to request retainers?

The ideal time to order retainers is once the doctor's treatment goals and the patient's preferences have been fully addressed and agreed upon by both parties.

**Reminder: We only do dual arch retainers. We do not do single-arch retainers.**

 

How long do patients need to wear retainers? Should they wear them for at least 22 hours per day? When can they switch to wearing them only at night? How long after completing treatment should they wear the retainers?

The duration for wearing retainers is determined by the retention protocol set by the doctor. This decision considers factors such as the type of treatment provided, the complexity of the tooth movements, patient compliance, and other relevant factors.

 

How often do we recommend patients replace retainers?

While on average retainers last between 6 - 12 months, it truly depends on the patient. Some things to consider that may reduce the life of a patient’s retainer are:

• Bruxism (teeth grinding): Bruxism puts excessive force on the retainer, leading to faster wear and tear.
• Nail-biting or chewing on objects: These habits can damage the retainer, causing cracks or chips.
• Smoking: Smoking can stain the retainer and weaken the material.
• Dry Mouth: Some medications like antidepressants or antihistamines can contribute or cause dry mouth. Saliva naturally helps to neutralize acids and lubricate the mouth but its absence can create an environment that's more favorable to retainer breakdown.

 

When are permanent retainers recommended?

Permanent retainers are beneficial for retaining teeth that have undergone significant rotation during treatment and when a patient strongly prefers them. They are also advisable for patients with a tongue thrust habit or for those who are at a higher risk of relapse due to inconsistent retainer use.

 

What type of wire should be used for a fixed lingual retainer?

The choice of wire for a fixed retainer depends on the doctor's preference and experience. Some doctors prefer using a single round wire, like a .032, which is contoured to fit the lingual surfaces of the aligned anterior teeth and bonded at the ends directly to the cuspids. Others opt for a "braided" or "twisted" wire, which is applied to the lingual surfaces of specific teeth and must be bonded to each individual tooth.
