Microscrews - Temporary mini implants which may be used in conjunction with your brace to help avoid tooth extraction or the use of head gear.

Modules - These are tiny doughnut shaped rubber rings that are used to hold the archwire in place. They come in lots of fun colours or an option of clear modules are available.

Retention Period - As soon as the braces are removed it is essential that  a retainer is used to hold the teeth in the corrected position.

Retainer (removable)) - Made from soft clear plastic that fits over the teeth like a gumshield.

Retainer (fixed/bonded) - A thin wire made from high quality stainless steel that is bonded to the back of the teeth and usually lasts between 7-10 years.

Separators - Little elastic rings that are placed between the back teeth to create a space for bands to be fitted a week later.

TPA - A  metal bar that goes across the roof of the mouth that connects to the bands on the upper molar teeth, it is used to keep the molars from moving into the extraction space left behind after an extraction has taken place.
