Bolton Analysis

Bolton Analysis (pronounced: Bohl-tuhn Analysis) is a method used in Orthodontics to determine the optimal tooth size ratio between the upper and lower teeth. It was developed by Dr. Wayne A. Bolton, an American orthodontist, in the mid-20th century.

Etymology

The term "Bolton Analysis" is named after its inventor, Dr. Wayne A. Bolton. The word "analysis" comes from the Greek word "analusis" which means "a breaking up, a loosening, releasing".

Definition

Bolton Analysis is a diagnostic procedure used in orthodontics to determine the discrepancy in tooth size between the upper and lower dental arches. It is used to predict potential problems in the final occlusion and to plan appropriate treatment.

Procedure

The Bolton Analysis involves measuring the width of each tooth from the first molar on one side to the first molar on the other side, in both the upper and lower dental arches. The measurements are then compared to the ideal ratios established by Bolton. Any significant discrepancy indicates a tooth size discrepancy that may need to be addressed in the treatment plan.
