11a.
If using a dual cure resin cement for both cementation and core build up such as Corecem
™
(recommended technique): Mix the cement and apply it in the post space from bottom to the top using
the root canal tips. Seat the post immediately. Light-cure for 40 to 60 seconds. Continue applying the
core build up using a plastic Coreform
™
matrix, or directly on the tooth.
11b.
If using separate cement and a core build up resins : Mix the cement* and apply it to the post and then
in the post space using a Lentulo spiral or a syringe tip. Seat the post immediately. Remove excess
cement with appropriate instruments. If using dual-cure cement, light-cure for 40 to 60 seconds, apply-
ing gentle pressure on the post with the tip of the curing light probe. Apply 2 coats of bonding agent*
to the exposed post(s), cement and involved tooth structure. Remove excess and air-dry with jet of air.
Light-cure for 20 seconds (if needed).
11c.
If using a self etching cement*, there is no need to etch and prime the post space. Mix the cement and
apply it in the post space from bottom to the top using a root canal tip. Seat the post immediately.
Remove excess cement. Light cure if needed. After etching, rinsing, drying, apply 2 coats of bonding
agent* to the exposed post(s), cement and involved tooth structure. Remove excess and air dry with
jet of air. Light cure for 20 seconds (if needed).
12.
Directly model the build-up using a composite core build-up material*. R.T.D. recommends that the
coronal end of the post be covered by core composite.
OTHER RECOMMENDATIONS
D.T. posts are single use devices. They must not be re-used to avoid the risk of contamination.
D.T. posts can be cleaned with alcohol. They can neither be sterilised nor disinfected in thermodisinfector.
D.T. posts can be sterilized individually in an autoclave with the following settings**:
•
Wrap individually in disposable sterilization pouches or tubing that comply with the regulation standard
in force in the country of use (e.g EN ISO 11607-1),
•
Autoclave: type B complying with regulation standard in force (e.g EN 13060),
•
Sterilization temperature: 134°C- sterilization time: 18 minutes,
•
1 cycle only.
A D.T. re-access kit is available if needed. Contact your RTD distributor.
D.T. Universal Drill and D.T. Finishing Drill: these instruments are supplied non-sterile. Disinfect and steril-
ize instruments before each use. Disinfect instruments with disinfecting or cleaning agents adapted
for rotary instruments*. Do not disinfect instruments in thermodisinfector. Inspect instruments visu-
ally before each use: change to new drills when they are damaged, corroded or dull. The universal
