Getting Started with Bassi Logic.

Bassi Logic™ is a monumental leap in heat treated rotary nickel titanium files. It’s advanced design and a single-file system make it unmatched in speed for instrumentation according to multilpe studies.

Bassi Logic Protocols

Before clinical use: The illustrations on this site and brief instructions are for introductory purposes. Consult the complete IFU and practice with the Logic files in extracted teeth and resin blocks before clinical use.

Standard Single Shaping File Protocol

This is the recommended technique working with Bassi Logic. The prepare is conservative, fast and yet familiar.

Click here for details on each step of the protocol

Step 1 – K-File

Begin with a K10 file in the first two thirds of the canal.

Step 2 – Glidepath Definition

Choose a Glidepath file – #25/.01, #30/.01, #35/.01 or #40/.01 – according to the diameter of the foramen. Perform soft to-and-fro motion until it reaches patency.

Step 3 – Root Canal Length Measurement

Proceed with odontometry.

Step 4 – Shaping the Canal

Choose a final shaping file – #25/.03, #30/.03, #35/.03, #40/.03, #25/.05, #30/.05, #35/.05 or #40/.05 – according to the diameter of the Glidepath file, which was defined by the diameter of the apical foramen, and the desired taper.

Perform a soft motion in the apical direction up to WL. If there is any resistance, a slight widening will be needed, and it can be done with the same file.

Step 5 – Irrigation

After canal preparation, insert the Bassi Clean™ irrigation file to WL and rotate (or reciprocate) in sodium hypochlorite and again in liquid EDTA for a minimum of 30 seconds each, optimally more.

NOTE: Irrigate every time you remove a file from the canal.

Difficult Patency Protocol

If patency is difficult to reach using the Standard Protocol, this method is an excellent workaround.

Step 1 – K-File

Begin with a K10 file in the first two thirds of the canal.

Step 2 – Glidepath File

In a case like this, the #25/.01 Glidepath file does not reach patency.

Option 1

Step 3.1 – Mini Joker File

Use a #15/.03 Mini Joker file in a very gentle movement towards the apex (no need to brush), until you reach patency.

Step 3.2 – Glidepath File

Use a #25/.01 Glidepath file until you reach patency.

Option 2

Step 4.1 – Hand File

Use Target #10 hand files until you reach patency.

Step 4.2 – Glidepath File

Use a #25/.01 Glidepath file until you reach patency.

NOTE: Irrigate every time you remove a file from the canal.

Calcified Canal Protocol

This is our most effective solution to achieving patency in calcified canals.

Click here for details on each step of the protocol

Step 1 – Hand File

Identify the calcification with a Target #10 hand file.

Step 2 – Joker File

Use a #15/.05 Joker file in brushing motion until you reach the calcification.

2.1 – K-File

Use a K10 file to make sure you have progressed towards the apex.

2.2 – Joker File

Repeat the #15/.05 Joker file step in case you have progress.

If the #15/.05 Joker file does not progress to patency, stop using it and go back to the K10 file.

2.3 – K-File

Repeat the process until the K10 file bypasses the calcification.

Step 3 – Hand File

Use a Target #10 hand file until you reach the apex.

Step 4 – Glidepath File

Use a #25/.01 Glidepath file until you reach patency.

NOTE: Irrigate every time you remove a file from the canal.

Retreatment Protocol

Removing Gutta-Percha effectively and safely.

Click here for details on each step of the protocol

/Step 1 – #30/.10 File

Insert a #30/.10 RT file passively and directly over the Gutta Percha, without solvent aid. Reach 2/3 of the canal at 950 RPM.

Step 2 – #25/.08 File

Use a #25/.08 RT file on Gutta Percha, without the aid of solvent, until it reaches the apical third.

Step 3 – Solvent

Only use solvent when using the #20/.06 file.

Step 4 – Hand File

If you find a ledge, use manual files.

Step 5 – Bassi Clean

Use a Bassi Clean file in rotary motion with final irrigation.

Bassi Logic Clinical Steps

Before clinical use: The animations on this site and brief instructions for introductory purposes. Consult the complete IFU and practice with the Logic files in extracted teeth and plastic blocks before clinical use.

1. Achieve Patency

Learn how to use a Logic Glidepath file to achieve patency.

2. Create the Glide Path

Step 2 - Glide Path & TWL Details

Canal anatomy dictates the Glide Path file chosen: Most teeth with relatively uncomplicated anatomy require the 25/.01 Glide Path file. All Glide Path files, including the 25/.01 are inserted with a gentle and slow pecking motion to the TWL.*

Tips

If desired, larger Glide Path files (30/.01, 35/.01, 40/.01) can be chosen to prepare a glide path in larger canals using a gentle pecking motion to TWL.

* If the chosen Glide Path file will not reach the apex, prepare the Glide Path manually and/or prepare the glide path with hand files in combination with the .05/15 Bassi Logic™ file. This file is used with a gentle apical insertion and lateral brushing motion on withdrawal. Do not attempt to force the file apically to achieve patency.

3. Shape the Canal

Step 3 - Shaping the Canal Details

Insert the Shaping file corresponding to the Glide Path file used above. For example, if the 25/.01 prepared the glide path, the 25/.05 Shaper is inserted with a gentle pecking motion for final canal shaping. If the 30/.01 Glide Path file was used, the 30/.05 Shaper is used, etc.**

Tips

Brushing Bassi Logic™ Shaper files against the thickest root wall (away from the furcation) can prepare a greater canal taper and/or enlarge the orifice if desired.

**If the clinician wishes to prepare a larger apical diameter, the 30/.01, 35/.01, and 40/.01 Bassi Logic™ files can be used.

4. Irrigation

Step 4 - Irrigation Details

After canal preparation, insert the Bassi Clean™ irrigation file to TWL and rotate (or reciprocate) in sodium hypochlorite and again in liquid EDTA for a minimum of 30 seconds each,optimally more.

Achieving Patency

Achieving patency by reaching the apical foramen in the final third of the root canal is crucial to maintaining cleaning efficiency in the clinical procedure. In the following video learn how to achieve patency using K-Files or Logic Glidepath files.

Retreatment

Step-by-step instruction on using Bassi Logic files for Retreatment. Bassi Logic Retreatment provide unique advantages, as they are designed to remove 90 percent of the gutta-percha without the use of solvents.

Clearing Obstructed Canals

with “The Joker” 15/.05

Occasionally in an endodontics procedure, there are significant obstructions in a canal that impede access to the apex. In this video learn how to use the Bassi Logic Glidepath 15/05, or “the Joker” to clear the obstruction.
