After active orthodontic therapy by an orthodontist Loveland, it is important to maintain the position of the teeth because the ligaments that fix them to the bone are very elastic and have a very good “memory”. Once the appliance is removed, the elasticity of the ligaments tends to make teeth return to their original position, which means that the effects of the treatment for which both the doctor and the patient put so much effort can be lost.
Therefore, a person who has worn an orthodontic appliance for 2 years must wear retainers for another year.
From a technical point of view, there are two types of retainers, namely fixed and mobile.
Fixed retainers are those that cannot be removed by the patient, being glued by applying an adhesive on the tooth enamel. The method is non-invasive and can be easily glued again, in case of being accidentally detached.
Mobile retainers are those that have several constructive variants. The Hawley retainer is made of an acrylic part and placed on the palatal arch; it can be adjusted to move the teeth continuously with the help of an arch adapted to the external surface of the teeth. The Zendura retainer is another variant made on the basis of pressure, being very resistant. Another model is the Essix retainer, in which the gutter is made on a vacuum basis, being transparent, comfortable and having a similar appearance to Invisalign devices.
