Bassi Logic Technique

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 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

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

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

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.

Electronic Motor Settings

Use a torque controlled endodontic motor. Refer to the rotational speed and torque settings in the chart provided below as suggested use.

Handpiece: Use either an 1:1, 4:1, 8:1 or 16:1 endodontic handpiece.

Motor Settings Chart:

• 350 RPM 1.5 Torque: 15/.03
• 350 RPM 2 Torque: 25/.01, 30/.01, 35/.01, 40/.01, 45/.01, 50/.01
• 950 RPM 2 Torque: 25/.03, 30/.03, 35/.03, 40/.03, 15/.05
• 950 RPM 4 Torque: 25/.05, 30/.05, 35/.05, 40/.05, 25/.06
