US 12,690,957 B2 · Vacuum drawn irrigation followed by instant obturation of a root canal system using a single staging assembly

Abstract

Embodiments of this disclosure provide a staging assembly for negative pressure, multi-canal irrigation of a root canal system followed by obturation. The staging assembly may be part of a kit that includes a plurality of catheters sized for insertion into the root canal system. To hold the catheter in its proper position in the canal, the catheter may include a stop and the staging assembly may include a corresponding stop hold. The distal end of the catheter can be positioned 2 mm to 5 mm from the terminus end of the root canal. The staging assembly is then sealed, creating a closed system. Irrigating solution is vacuum-drawn out the ends of the catheters and debris is evacuated through a vacuum port of the stating assembly. During irrigation, no hands on time is required by the clinician. After irrigation, vacuum is reversed to dry the canal. Obturation occurs through the vacuum.

Dependent claims

A system for use in irrigation of a human tooth root canal system, the system comprising:

a staging assembly (10) including:
a staging skirt (11);
and
a staging ring (13) adjacent, and connected to, the staging skirt;
the staging skirt made of a first material and flexible, the staging ring made of a second material and rigid;
the staging skirt further including flaps (12) defining a cavity (15) having a predetermined size for connection to a human tooth;
the staging ring further comprising:
a catheter fence (17) including, at a forward end, a plurality of spaced-apart catheter-slots (29);
wherein, the catheter fence defines an open, fenced-in area (47);
a top plate (45) sized for insertion into the open, fenced-in area of the catheter fence, the top plate including a port (49), wherein the top plate is located within the catheter fence rearward of the plurality of catheter slots and forms a single chamber containing at least one catheter when the at least one catheter is inserted into a corresponding one of the plurality of catheter slots;
wherein the system does not require an electrical source for operation.
