Orthodontic Dental Light-Cure Paste Adhesive Bonding

We are the sole agent of Prime Dent in Asia.

Instroduction of Usage:

PROPHYLAXIS:

Using a rotary instrument with a rubber cup or brush, prophy the enamel surfaces to be

bonded with Prime-Paste or plain pumice. Do not use prophy pastes which contain oil, as

they can leave a film that will inhibit the etch. Special attention should be given to the

lingual surface and posterior teeth where patient hygiene may be poor and tartar and

calculus may be in excess. Rinse thoroughly and dry teeth with oil and moisture-free

compressed air.

ETCH:

Dispense etching agent onto mixing pad.Etchant may be liquid or gel. Isolate the teeth for

etching. With a cotton pledget or brush, dab the etching agent onto the entire area to be

bonded. Do not rub the etching area on the enamel. Allow 30 seconds for etching (60 for

deciduous teeth). Avoid placing etching agent on soft tissue.

RINSE & DRY :

Rinse thoroughly with water and spray combination to properly cleanse the enamel surface.

Rinse each tooth with copious amounts of water for 10 seconds (20 seconds with gel etch)

to stop the etching process and remove demineralized particles. Reisolate and dry teeth

throughly. The etched area should appear frosty white. If not, re-etch for an aditional 20

seconds.

APPLICATION OF SEALANT:

Dispense a drop or two of sealant resin onto the mixing pad. With a brush, apply a thin

uniform layer of sealant to the etched enamel. It is not necessary to cure the sealant at this

time. A cured salant can also prevent brackets, a thin coat of sealant can be painted on

metal bracket base and cured for 10 seconds before applying paste.

APPLICATION OF PASTE. 

Using Prime-DENT Light Cure Adhesive Paste syringe tip or a spatula, apply the paste and

work it into the  bracket base. Place bracket on the tooth and press in the desired position.

Caution should be taken not to expel all of the paste from beneath a metal bracket. With a

metal bracket, position the curing light to shine from the incisal adge and illuminate for 10

seconds and then 10 additional seconds from the gingival, mesial or distal bracket edge.

With a ceramic bracket from the labial for 20 seconds. The light director must be placed as

close to the bracket base as possible during curing, an active arch wire can be placed

immediately.

Note:

Curing times depend on the intensity of curing light. The total curing time can range from 6

seconds to 20 seconds. Please refer to light manufacturer for recommended curing times.
