Are you aware of canalis sinuosus

Canalis sinuosus is a tortuous canal seen in the upper jaw. This structure was first identified by Frederic Wood Jones who identified this structure as an anatomic variability. It was found that this structure could influence the placement of the dental implant especially in the front region of the upper jaw.

What is Canalis sinuosus?

Canalis sinuosis is a canal which caries final branch of anterior superior alveolar nerve which takes a curved path as it passes down from in front of the nose, it curves as it passes down and then finally may reach above the front tooth region. The name is derived from latin which signifies the curved path of the canal. It contains nerves and arteries.Placing implant in this region requires excessive assessment using Computed Cone Beam Topography(CBCT) and treatment planning.

Why is it important?

Improper planning and placement may result in unnecessary complications in the future. This includes

• Post operative bleeding

• Implant failure

• Pain

• Swelling

• Difficulty during chewing

• Misdiagnosis as other pathology

• Overinstrumentation during root canal treatment causing pain

Why is CBCT important?

CBCT is a great tool in assessing this complex structure. It provides insight regarding the diameter, the course, the numbers and various other factors that may influence the success of an implant.

Canalis sinuosis contains lots of accessory and minute canals which are impossible to assess using 2D radiographic imaging. Proper assessment and evaluation is absolutely necessary for any operative procedures in this region
