Overview Orthodontic treatment often evokes questions about third molars, or “wisdom teeth.” Our clinical advisor, Dr. Ken Fischer, has some answers: “What should be done with the third molars?” Although frequently congenitally missing, the presence of those teeth, erupted or unerupted, may influence the doctor’s treatment planning. For example, if the second molar needs to be distalized or uprighted, the […]

Basic Principles for Intrusions & Extrusions For basic principles or intrusions and extrusions, refer to the following: 1. A tooth that’s not upright will not extrude or intrude easily. 2. Place a horizontal engager and tilt it upright first. 3. Make sure there is adequate interproximal space; use IPR where appropriate to make space and prevent collisions. 4. Then extrude or intrude […]
For information regarding Auxiliaries and Clear Aligner treatment, refer to the following steps: NOTE: The term “auxiliaries” as used in orthodontic treatment with clear aligners refers to an entity or item that may be used in conjunction with clear aligners to enhance the movement of, or effect a change in, the teeth or skeletal components. Some […]
Definition Extruding with auxiliaries is a technique used to extrude a tooth that has not erupted as desired to create an aesthetically aligned smile. Extrusions are one of the more difficult movements to achieve with clear aligners. It is important to watch for extrusions not occurring with your cases, as this can be one of the reasons […]
Definition Rotating is when you turn a tooth around its long axis. One method to rotate teeth is with the use of auxiliaries, such as buttons and elastics. One button is placed on the tooth to be rotated while another button is placed on an ‘anchor’ tooth. The goal is to provide rotational correction of a tooth without […]
Definition Rotating is when you turn a tooth around its long axis. Uses Rotating a tooth can be difficult. Various factors can get in the way or the tooth may just not want to turn. Crowding, not enough pressure, patient non-compliance and degree of rotation needed, can all affect treatment progression and results. How to help Tooth […]
Know before you go IPR (interproximal reduction) is a procedure where, by reducing the proximal surfaces of the teeth, a very small amount of space between the teeth is created to allow the teeth to move during treatment. IPR is often recommended when treating patients with clear aligners. There are a number of important things to […]
Definition IPR stands for interproximal reduction. It is the process of creating very small amounts of space between pairs of teeth in order to allow the teeth to move as needed during treatment. IPR is used to create space between teeth by reducing the proximal surfaces of the teeth, when needed or called for in […]
Definition The engager is made up of dental composite material, so a good general guideline for removing engagers, would be to use the same methods that you would use to remove composite from the tooth. Uses For removing engagers that are no longer necessary. Removing Engagers Parts needed Highspeed handpiece with water irrigation White stone or multi-fluted […]
Definition Engagers can sometimes fall off after you put them on. The reason why composite falls off is usually a failure of the etching and bonding agent. Causes The most common cause for why an engager might fall off when removing the aligner, is that the composite has not fully adhered to the tooth. Bond failures […]
