The content of this article was developed with Dr. Gabriel Dolci of PUSH Dental Learning. Overview When clear aligner therapy was introduced, there were limitations regarding its indications in extraction cases, specifically cases which would require major root movements or movements of larger teeth over greater distances. However, advances in the quality of aligner plastic […]

Definition There are circumstances that may prevent a tooth from achieving its complete movement as designed in the setup. Overcorrection is a method for providing sufficient pressure on a tooth to move it into the optimal position, and commonly recommended by experienced clinicians. Uses Overcorrection is commonly needed for these types of movements: Rotations Labial-lingual […]
Xyzal is a common “over the counter”(OTC) drug (antihistamine) used for allergy relief. Some animal studies have suggested that antihistamines, especially H1 blockers, can affect the osteoblastic/osteoclastic activity of bone remodeling resulting in an inhibiting of the tooth movement process, the degree of which is undetermined. With normal use as directed by the manufacturer and […]
Definition An incisal gap (large or small) is when there is a gap between the incisal edge of the tooth and the aligner. Incisal gaps are usually the first sign of a case going off track. Causes Incisal gaps can be caused by any of the following: Patient is non-compliant and has not followed the recommended […]
Definition Rocking is when one side of the aligner first but the other does not. The side that is tracking will fit nicely (flushed), but the side that is tracking poorly will not want to sit at all. Trying to sit the aligner on either side yields the same results since the aligner will react […]
Definition An aligner is considered too big for the patient when it is obviously too wide or too long for the patient’s arch; there can also be difficulty with the aligner remaining in place while the patient speaks/opens their mouth. Too Big An aligner is considered too small when it cannot easily be placed into […]
Definition Backtracking is when you have a patient wear the previous aligners longer than originally planned. Often, when the teeth have gone off track, they need additional time in a previous aligner/step to move fully into position. Backtracking gives the teeth the time that they need to get back on track with treatment. Uses Indicators for when backtracking may […]
Definition Bisphosphonates are a class of drugs that are used to treat osteoporosis and other diseases involving bone fragility and/or loss of bone mass. These drugs effect bone metabolism by inhibition of osteoclastic activity. The disruption of bone metabolism may have as small of an effect as slowing the rate of tooth movement during orthodontic treatment to […]
