The objective of this study was to determine the location of the gingival zenith in relation to the vertical axis of the upper anterior teeth and the lateral incisors in relation to the gingival zeniths of the adjacent proximal teeth. Methodology: A total of 44 patients treated at the Advanced Dentistry Clinic San Marcos between October and November 2022 were evaluated. These patients were asked to participate in the study by signing an informed consent form. With their authorization, an alginate study model was taken, which was immediately poured with dental stone. The gingival zenith analysis was performed on the study model, where various tracings were made to identify the gingival zenith, its location, and its displacement in millimeters from the vertical axis of the dental piece, as well as its position relative to the adjacent teeth. Results: The location of the gingival zenith relative to the vertical axis for the upper central incisors was 1.01 mm and 0.99 mm, while for the lateral incisors, it was 0.70 mm and 0.80 mm, and for the canines, it was 0.50 mm and 0.48 mm. Additionally, the right and left lateral incisors showed a distance of 0.90 mm and 0.85 mm from the tangential line formed between the zeniths of the central incisors and canines. Conclusion: The gingival zeniths of the right and left central incisors, lateral incisors, and canines were mostly found towards the distal, while the lateral incisors were mostly found towards the coronal of the tangential line formed by the zeniths of the adjacent teeth.
