Mesiodistal and Buccolingual Tooth Dimension Measurement in Orthodontic Space Analysis and Bracket Positioning
The Boley Gauge, Ortho Style is a gauge and measuring instrument in the orthodontic instruments category, manufactured by BusinessMed Instruments®. It is indicated across three surgical disciplines: orthodontics, restorative dentistry, and prosthodontics.
The Boley Gauge, Ortho Style measures the mesiodistal diameter of the permanent dentition, the buccolingual diameter of the permanent dentition, the mesiodistal tooth width discrepancy between maxillary and mandibular teeth, and the facial axis of the clinical crown in space analysis, bracket positioning, and tooth dimension measurement.
Vernier Sliding Scale and Pointed Tip Mechanism
The Pointed Tips for Internal/External Measurement with 0–100 mm Scale with 0.1 mm Accuracy contact crown surfaces at interproximal contact points, incisal edges, and external tooth dimensions to register measurements across the full 0–100 mm range. The Vernier Sliding Scale with Integrated Locking Thumb Screw advances along the main beam to record the measured value. The integrated locking thumb screw fixes jaw position at the reading for transfer and documentation.
Intraoperative Dimensional Consequence
Momentary pointed-tip contact with enamel at interproximal contact points of permanent dentition produces no structural enamel change. The Boley Gauge, Ortho Style supports calculation of the Bolton anterior ratio (target 77.2%) and overall ratio (target 91.3%) through measurement of the mesiodistal tooth width discrepancy between maxillary and mandibular teeth. Undetected tooth size discrepancy is documented in up to 17.4% of orthodontic patients; vertical bracket placement error at a mean of 0.34 mm per tooth produces residual torque deficiency and an extended finishing phase.

Clinical Uses and Applications
- The mesiodistal diameter of the permanent dentition is measured on diagnostic casts in space analysis to calculate Bolton anterior and overall ratios for interarch tooth size discrepancy diagnosis.
- The mesiodistal tooth width discrepancy between maxillary and mandibular teeth is quantified in space analysis to determine extraction, expansion, or interproximal reduction requirements.
- The intercanine width of the maxillary and mandibular arches is measured in space analysis to evaluate arch form and identify constriction requiring expansion.
- The intermolar width of the dental arch is measured in space analysis to assess posterior arch width for treatment planning.
- The facial axis of the clinical crown is measured in bracket positioning to confirm vertical bracket slot height from the incisal edge or labial cusp tip prior to adhesive set.
- The interproximal contact points of permanent dentition are measured in tooth dimension measurement to determine restorative margin placement and interproximal space availability.
- The buccolingual diameter of the permanent dentition is measured in tooth dimension measurement for prosthodontic crown fabrication to prevent over-contoured cervical profiles.
- The mesiodistal width of maxillary and mandibular permanent teeth is measured on diagnostic casts in preoperative space analysis to establish arch length discrepancy in millimetres.
