PrepGauge

Haven’t you heard your technician saying, “The reduction isn’t enough”? What if your preps could speak for themselves — measured and verified with the PrepGauge?

Our food-grade silicone gauges let you confidently quantify every reduction with easy, color-coded strips — built on the trusted feeler gauge concept explained in the how-to-use guide and video below.

No more second-guessing. No more repeats. Just predictable preps and smoother lab communication.

• Crown Preparations — PFM, Zirconia & Lithium Disilicate — Verify adequate occlusal, palatal, and proximal reduction before sending to the lab.
• Full Mouth Rehabilitation — Ensure consistent and material-appropriate clearance across multiple units for predictable prosthetic outcomes.
• Anterior Veneer & Crown Preps — Confirm precise reduction at narrow anterior sites using the tapered 1 mm tip of the boomerang design.
• Posterior Molar Preparations — Use the wide 10 mm arm for reliable clearance assessment over functional and non-functional cusps.
• Cases with History of Lab Remakes — Ideal for practices aiming to reduce remakes and improve first-time fit accuracy.
• Teaching & Training Environments — An objective, tactile tool to guide dental students and residents toward prosthetically sound preparation standards.

• Quantifies Tooth Reduction — Eliminates guesswork for occlusal, palatal, and proximal clearance with an objective, measurable assessment at the chair.
• Color-Coded Silicone Gauges — Four distinct thicknesses for instant identification: 1 mm (Yellow), 1.5 mm (Blue), 2 mm (Green), and 3.5 mm (Pink).
• Universal Material Compatibility — Designed for use across PFM, zirconia, lithium disilicate, metal, and more restorative materials.
• Feeler Gauge-Inspired Design — Delivers reliable tactile feedback that tells you exactly whether reduction is adequate, insufficient, or excessive.
• Boomerang Shape — Ergonomically designed to fit seamlessly across both anterior and posterior regions of the arch without repositioning.
• Autoclavable & Reusable — Crafted from durable, biocompatible food-grade silicone that withstands repeated sterilization cycles.
• Compact Storage Case — Keeps all gauges hygienic, organized, and instantly accessible at the chairside.
• Reduces Lab Adjustments & Remakes — Ensures restorations fit predictably the first time, minimizing costly and time-consuming adjustments.
• Patent-Protected Innovation — An exclusive, clinician-designed system developed by Prof. Dr. Moez Khakiani for real-world prosthetic precision.

• Step 1: Complete Your Preparation — Using the appropriate diamond burs, complete the gross tooth preparation to the best of your clinical judgment.
• Step 2: Choose the Correct Gauge — Select the appropriate thickness based on the restorative material and the region being assessed:
  • 1 mm (Yellow) — Non-functional cusps: LiDiSi, PFZ, metal, zirconia
  • 1.5 mm (Blue) — Functional cusps: LiDiSi, PFZ; non-functional cusps: PFM
  • 2 mm (Green) — Functional cusps in PFM preparations
  • 3.5 mm (Pink) — Significant PFM reductions involving antagonist teeth
• Step 3: Place the Gauge & Perform the Push Test — Ask the patient to bite down in Maximum Intercuspation and attempt to push the PrepGauge strip between the prepared surfaces:
  • Use the wider arm (10 mm) for molar assessments
  • Use the narrower arm (7 mm) for premolars and smaller teeth
  • Use the tip (1 mm) for mandibular anteriors
• Step 4: Make Your Clinical Assessment — Interpret the resistance encountered during the push test:
  • Cannot push the gauge → Inadequate reduction; further preparation required
  • Minimal resistance → Adequate clearance achieved
  • No resistance → Over-reduction or improper occlusion; verify with articulating paper
• Step 5: Optional — Use with a Color Indicator — For added diagnostic clarity, apply an occlusal indicator paint such as Arti-Spot or Bausch Spray to precisely visualize areas of insufficient reduction before finalizing the prep.
