Abstract: Abstract Rim Guide is a compact, notch-integrated occlusal rim precision gauge designed to provide accurate, stable, and reproducible measurement of occlusal rim dimensions during denture fabrication. The device comprises a rectangular metallic measuring blade of approximately 3 em in total length, with an active calibrated range of2.5 em and an additional 0.5 em buffer zone. A central longitudinal slot is incorporated within the blade to enable direct visualization and alignment of the occlusal rim with the scale markings. Graduations with fine subdivisions are provided to enhance measurement precision. A key structural feature of the invention is a perpendicular step of approximately I em length extending from the base of the measuring blade. This step is oriented at a right angle to the blade and functions as a stable reference platform that rests against the occlusal rim or supporting surface, ensuring consistent positioning and perpendicular alignment during measurement. The step connects the measuring blade to an ergonomic handle, which is aligned parallel to the blade for improved grip and balance. The measuring blade includes longitudinal notches at 18 mm and 22 mm for rapid determination of anterior occlusal rim length corresponding to mandibular and maxillary standards. Additionally, transverse notches of 6 mm, 8 mm, I 0 mm, and 12 mm are provided along the superior edge for assessing occlusal rim width. These notches also function as guides for transferring markings onto the wax rim using a heated instrument. The integrated design enables simultaneous measurement, alignment, and marking, reducing operator error and improving efficiency. The device ensures standardized occlusal rim fabrication with enhanced clinical reliability and reduced chairside time.
