Abstract

An easy, fast, and effective method for accurate fabrication of study models is described here. This clinical innovation will enable the students and orthodontic professionals to standardize their study models as per international standards.

Highlights

Study models accurately represent the teeth, their supporting tissues and the relationship between upper and lower teeth in centric occlusion
Fabrication of plaster study models is time consuming as it requires great trimming of the plaster bases
We describe a new method of fabricating dental models using guide plates making it easier to achieve standardized study models accurately every time

Summary

Introduction

Study models accurately represent the teeth, their supporting tissues and the relationship between upper and lower teeth in centric occlusion. They contribute greatly to diagnosis and treatment planning, to compare pre‐ and post‐treatment changes and are valuable instructional and illustrative aids during consultation with patients.[1]. Accurate trimming of orthodontic study models facilitates proper diagnosis and treatment planning. Well‐trimmed, esthetically pleasing models, reflect the practitioner’s attention to detail and are a part of the patient’s legal treatment record.[2,3]. American board of orthodontics prescribes certain specifications for plaster study models for universal acceptance.[4]. Fabrication of plaster study models is time consuming as it requires great trimming of the plaster bases. Achieving parallelism between the bases is difficult as there are no mechanical aids to orient the bases
