Precision Occlusal Splints

Precision Splints

Now it is possible to make 3D printed Splints (Permissive or Directive) based on the indication in a given case.


Upper and lower models mounted on the Semiadjustable articulators with values of incisal condylar and Bennett movements clearly instructed in order form.


  • Bruxism
  • Full Mouth Rehabilitation
  • TMD
    • 1. Myofacial pain associated with the muscles of mastication and group muscular functions of occlusion.
    • 2. Internal condylar derangement due to dislocation of the TMJ, condylar disc or injury to the condyle.
    • 3. Degenerative and/or inflammatory diseases.
    • 4. Loss of vertical dimension due to excessive grinding while bruxing and clenching.
  • Functional Jaw deviation
  • TMJ ankylosis Unilateral or Bilateral


1. Scan

Collect patient anatomy digitally using an intraoral scanner, or scan a physical model or impression using a desktop scanner.

2. Design

Import the scan data into CAD software and design the treatment.

3. 3D Print

Import the designed CAD file into PreForm print preparation software for print setup and send it easily to a Formlabs printer.

4. Prepare

Wash, dry, and post-cure the printed parts using Form Wash and Form Cure.

5. Polish and Finish

Remove support structures, lightly grind the splint to smooth any remaining imperfections, and polish it to shine.

6. Complete

The finished splint is ready for delivery to the dentist for fitment chairside.


Thermoformed Splint


  • Inexpensive
  • Good Retention
  • Clear


  • Premature posterior contact. Fulcrum that can lead to open bite and super- eruption
  • No functional occlusion
  • No anterior guidance
  • Wears quickly
  • Stains easily
  • Unbalanced

3D Printed Splint


  • Retention- Superior fit
  • Balanced occlusion with even contacts
  • Balanced functional occlusion in excursions
  • May incorporate anterior guidance with cuspid rise
  • Independent condylar settings in trauma situations to mimic natural hinge and rotary
  • Enforced minimal thickness allows proper vertical opening even in the deepest portions of the bite
  • Very durable
  • Less impervious to stain
  • Clear
  • Can be fabricated from intraoral scans or digitized from physical models


  • Printing can cost a little more
