Intrusion is a term used in orthodontics that refers to the movement of a tooth up into the bone. It is most commonly used to refer to the movement of a front tooth that has been pushed forward and is now sitting in front of its neighboring teeth. This movement is also referred to as an intrusive movement or an intrusive force.
Intrusion is used to correct an overbite, which is a condition where the upper front teeth overlap the lower front teeth. In order to correct the overbite, an orthodontist may use an intrusive force to move the upper front teeth back into the correct position.
Intrusion can also be used to correct other irregularities in the bite. For example, it can be used to widen the arch of the teeth or to reposition the jaw. It is also used to treat a crossbite, where the upper teeth are not properly aligned with the lower teeth.
When an intrusive force is applied, it is important to monitor the movement of the tooth so that it does not move too far or too quickly. If the movement is too rapid, it can cause damage to the surrounding teeth or gums.
Intrusion is a common procedure in orthodontics and can be used to correct a wide range of dental problems. It is important to speak to your orthodontist about any concerns you may have regarding the procedure and discuss the potential risks and benefits.
