We use the “Empower” bracket which is a self-ligating bracket manufactured by “American Orthodontics”, a company that prides itself in selling only “Made in the U.S.A.” products.
The top front braces can be the almost invisible ceramic brackets or metal brackets. Dr. Griffies only uses metal on the bottom teeth because ceramic brackets have the potential to cause wear to the top teeth if they rub together.
Take a look at the brochures to understand the advantage of using a “self-ligating” bracket for your orthodontic treatment.
The lower lingual arch is used both as a Space Maintainer in young patients without all of their permanent teeth and an “anchorage” appliances in patients with full braces.
From the side the back molars occlude in a good Class I relationship (we want them to stay just like this). In order to obtain a good bite the lower front teeth need to be moved back under the upper front teeth. With removal of one tooth on either side the canine teeth will be moved into the place of the first premolar and the lower front teeth brought back.
This patient is missing two lower baby teeth and we are awaiting the eruption of the two permanent premolars. The lower left back molar will have a tendency to move forward and block the eruption of the premolars. The Lingual arch will maintain the space and prevent movement of the molar forward.
The Nance Holding Arch is used both as a Space Maintainer in young patients without all of their permanent teeth and an “anchorage” appliances in patients with full braces.
The upper canine is forward of where it should be so an upper first premolar is removed and the canine brought back into position.
This shows the Nance in place with a space available after removal of the tooth. The blue on the back molars is the “bite plate” which helps prevent the top teeth from hitting the bottom brackets and also opens the bite slightly to allow easier movement of the canine tooth.
This patient is missing two upper right baby teeth and we are awaiting the eruption of the two permanent premolars. The upper right back molar will have a tendency to move forward and block the eruption of the premolars. The Nance Holding arch will maintain the space and prevent movement of the molar forward.
Approximately 5 months later the two permanent premolars and the upper left premolar have erupted into place.
The Palatal Expander is used to increase the width of the upper jaw to correct cross bites and expand a narrow jaw to the correct width.
Expansion of the palatal expansion is accomplished using a small “key” to turn the middle jackscrew of the expander.
The upper teeth on the right are position to the inside of the lower teeth. This is called a posterior cross bite.
The transpalatal bar fits on the roof of the mouth and anchors the molars in place while the remaining teeth are moved with braces. The transpalatal bar can also be used to move the molars either to expand or turn.
A transpalatal bar was placed and slowly constricted to correct the overexpansion of the back teeth.
An upper wire bonded to the inside of the upper front teeth maintains their position. Dr. Griffies recommends maintaining both the upper and lower retainers for a minimal of one year. They however can be maintained for longer periods to insure retention of the correction.
Clear plastic retainers are also worn for the first year after treatment and then weekly there after. Unfortunately teeth will continue to shift as we age and the best way to prevent movement is to use a retainer periodically to insure shifting is kept to a minimum.
