Introduction: edentulism is a fairly common problem, and adequate knowledge of the anatomy and physiology of the oral cavity is essential in the recovery and neuromuscular balance of the stomatognathic system. The use of reference lines together with the occlusal plane guide the positioning of the artificial teeth, which are used to construct the total dentures. Objective: to compare the extra-oral and intra-oral measurements of the width of the anterior teeth with the measurements of the reference lines recommended in the literature for making a total prosthesis. Methods: cross-sectional observational study with a non-probabilistic sample, with 50 individuals of both sexes, where a dental and facial analysis was carried out using photographs and a digital caliper. Results: it was observed that most of the individuals analyzed did not coincide between the width of the teeth and the reference lines, and that the analyzed women showed less coincidence between teeth and the width of the nose wing when compared with men (8.3% and 91.7%, respectively), with p = 0.001. Conclusion: the reference lines did not coincide with tooth size in most cases analysed.
