HARVARD MTA XR Flow EWT OptiCaps and EndoDirect Syringe Instruction Manual

HARVARD MTA XR Flow EWT OptiCaps and EndoDirect Syringe

MTA cement, flowable, with extra long working time and EndoDirect syringe Harvard MTA XR Flow EWT OptiCaps is a biocompatible repair cement in OptiCaps®. Due to it’s flowable consistency in combination with a long working time, Harvard MTA XR Flow EWT SET is the ideal choice for rootend fillings (orthograde). Harvard MTA XR Flow EWT powder consists of very fine hydrophilic particles of several hydraulic mineral oxides. After contact with the liquid it forms a gel that hardens to an impermeable barrier. Harvard MTA XR Flow EWT OptiCaps® are easily activated and the content of the capsule is easily ejected with the Harvard Applier OptiCaps®. Mixing of Harvard MTA XR Flow EWT OptiCaps® (mixing time 30 seconds) is achieved by a high frequency mixer with about 4,300 oscillations/minute.

Indications

• Apexification / Root-end filling (orthograde)

Contraindications/side-effects None known.

Activation and mixing

See “Instructions for the activation and mixing of Harvard OptiCaps®” Mixing time for the Harvard MTA XR Flow EWT OptiCaps® is 30 seconds.
Attention:
Avoid lag times between the processes of activation, mixing and application as the material is in the process of setting and lag times may impair or prevent application of the material. The material must be extruded within 10 seconds after the end of
mixing. To prevent dehydration during setting, apply Harvard MTA XR Flow EWT immediately after mixing.

Working time

Working time at 23° C (from the start of mixing): 4:00 minutes

Application

Place rubber dam and clean the root canal system using intracanal instruments and irrigate with NaOCl. Dry the root canal with paper points. For disinfection place calcium hydroxide paste in the root canal and seal the access opening with a temporary filling material. After one week remove the calcium hydroxide paste from the root canal
system. Check the Harvard MTA EndoDirect syringe for tightness of the endo tip.
Note: Use only the fitted endo tip in combination with the Harvard MTA EndoDirect syringe!
Mark the working length with the silicone stop and bent the endo tip – if desired – at an obtuse angle. Remove the plunger from the syringe. Mix a capsule of Harvard MTA XR Flow EWT OptiCaps® as described under item 1 and transfer the mixed material into the Harvard MTA EndoDirect syringe. Apply the required amount of MTA flow EWT into the apical region. Create a 3 – 5 mm barrier of MTA cement. Check the position of Harvard MTA XR Flow EWT by an X-ray. If an adequate barrier has not been created, rinse the MTA cement out of the canal and repeat the procedure. At the earliest 10 minutes after application of the Harvard MTA XR Flow EWT place a cotton pellet in the access to the root canal and apply a temporary filling material. Alternatively seal the root canal with a suitable root canal filling material and seal the cavity with a tight filling.
Notes

• In the first hour after application handle the placed MTA cement carefully.
