Ruler Wedge

The Ruler Wedge is manufactured from medical-grade stainless steel, featuring a flat tapered body that narrows progressively from a base width of approximately 20mm down to a sharp pointed tip, measuring approximately 100mm in overall length. Both lateral edges carry engraved millimeter graduation markings numbered sequentially from 1 through 8, allowing direct width measurement at any point along the taper. The flat profile and consistent taper geometry enable stable insertion into narrow anatomical spaces without lateral rocking or positional instability.

The progressive taper geometry of this tapered dental measurement wedge allows the clinician to insert the instrument to varying depths and read the corresponding width measurement directly from the engraved scale at the contact point, eliminating the need for separate caliper instruments during quick chairside assessments. The wedge ruler is manufactured entirely from stainless steel, making it fully autoclavable at 134°C and resistant to corrosion, surface oxidation, and scale fading through repeated sterilization cycles without dimensional deformation.

The Ruler Wedge is used by prosthodontists, restorative dentists, and oral surgeons as a dental interdental wedge gauge during crown preparation assessment, interproximal space measurement, implant site width verification, and orthodontic diastema quantification procedures. The clinician inserts the tapered tip into the target space, interproximal contact, edentulous ridge, or preparation margin, and advances it until resistance is felt, then reads the graduation marking at the contact point to determine the precise spatial dimension.

Leader Surgical demonstrates its range as a surgical instrument supplier by including measurement tools like this wedge ruler alongside its surgical instrument catalog, reflecting a brand that equips dental clinicians with every chairside assessment tool needed across restorative, implant, and orthodontic workflows, not just operative instruments alone.

How many wedges do I need to make a full circle?
It depends on the degree of your ruler. For a 10-degree ruler, you need 36 wedges to complete a 360-degree circle. A 9-degree ruler requires 40 wedges.
