How to Create a Proper Glide Path [White Paper]

The principle idea of straight-line access into the pulp chamber is widely accepted, but it’s the concepts surrounding glide path creation that are sometimes misunderstood. The glide path can often be irregular in many teeth, requiring great care to follow the natural path of the canal.

No one understands this more than Dr. David Landwehr, who discusses appropriate glide path procedure and instrumentation techniques in his white paper – Proper Glide Path Technique.

As Dr. Landwehr explains, there is no need to fabricate the glide path within the root canal. The original tooth anatomy should remain intact during the procedure. The glide path is just the natural space that was once home to healthy dental pulp.

But following the natural canal anatomy is sometimes easier said than done. In his white paper, Dr. Landwehr address several common questions and challenges clinicians could face in this endeavor, such as:

“A proper glide path must be followed, not made.”

– Dr. David Landwehr

  • What file size to begin with.
  • How to select the proper sequence of files.
  • What to do when meeting resistance with a #10 K-file.
  • How to achieve the best coronal access.

Ultimately, overcoming these challenges to create a path that follows the natural canal anatomy paves the road for a smooth shaping process. A predictable, reproducible glide path will allow rotary instruments to shape the apical terminus of the root canal, reducing the chance of  breaking an instrument.

Dr. Landwehr reviews several different approaches and products as well as the types of cases for which they are ideal. Read and download the full white paper here to see why Vortex Blue, PathFile and ProGlider are his go-to products for accomplishing the desired glide path.
