“…In the current study, the mean depth of the COS was measured at 1.0564 mm, which presents an interesting comparison to previous research. For instance, the work by Steven D. Marshall et al [48] in 2008 reported a mean COS depth of 1.92 mm, while another study by Krishnamurthy et al [49] (2017) indicated a mean of 1.56 mm. These variations in COS depth measurements across different studies highlight the diversity of occlusal curvature present in various populations and underscore the influence of demographic, skeletal, and dental factors on the COS.…”

Background: This study aimed to investigate the relationship between the Curve of Spee (COS) depth and malocclusion characteristics in a population from Sibiu County, Romania. The research sought to understand how the COS’s anatomical dimensions correlate with different classes of malocclusion and the position of the frontal teeth. Methods: A total of 265 participants from the Dentistry Ambulatory of the Military Hospital of Sibiu were included in this study. It employed digital intraoral scanning technology to measure the COS, overjet, and overbite, with malocclusion classification. Statistical analyses, including correlation and regression, were conducted to examine the relationships between COS depth, frontal teeth position, and malocclusion characteristics. Results: The average COS depth measured was 1.0564 mm, presenting variability when compared to existing literature. Most of the study participants had Class I malocclusion. A significant positive correlation between COS depth and overjet was identified, with no notable gender-based differences in these occlusal parameters. Conclusions: The findings affirm the integral role of COS in occlusal dynamics and malocclusion diagnosis. The COS measurement of a mean of 1.0564 mm, when compared to other results emphasizes the differences in occlusal curvature among various populations. The results contribute to a refined understanding of occlusal relationships, supporting the need for personalized orthodontic and prosthetic treatments based on precise anatomical measurements.

“…Orthodontists rarely evaluate and treat patients considering the curve of Spee (COS) in all situations hence the need of cephalometric and anthropometric planning is pivotal. Dental discrepancies as well as consideration of the curvature of Spee are significant diagnostic factors which should not be left undocumented [17,18]. Evaluation of the Spee curve's connection to the understanding of odonto-skeletal morphology is critical.…”

Background and Aim: The curve of Spee (COS) is a physiological entity in human dentition. A functional masticatory system necessitates an appropriate occlusal curvature. The primary objective of this investigation was to assess the skeletal and dental parameters in individuals with variation in the depth of curve of Spee. Materials and Methods: A total of 276 patients with pre-treatment lateral cephalograms and dental cast models were investigated in the Orthodontics and Dentofacial Orthopedics Unit of a Tertiary Care Hospital of Mardan, Pakistan from January 2021 to December 2022. Patients with no prior history of orthopedic treatment for functional jaw, prosthodontic treatment, no prior history of cleft lip and palate and cranio-facial disorders were enrolled. Ethical approval was obtained and all the patients were categorized into three groups based on the depth of curve of Spee (COS): Group-I (flat curvature < 2 mm), Group-II (normal curvature 2-3 mm), and Group-III (deep curvature > 3 mm). Lateral cephalometric analysiswas done to measure the four angular and four linear parameters. Molar relation, overbite, COS depth, and overjet were measured based on the occlusal classification. SPSS version 27 was used for data analysis.

“…This means that, in large measure, the curve of Spee develops as a dental (not skeletal) event [9]. Hence it is important to know the values of the depth of the curve of Spee for the specific age group and in a given population [2].…”

“…One of the key clinical steps in the rehabilitation of multiple long span posterior restorations is the re-establishment of the occlusal plane. The restoration of compensating curves forms the basis for ideal teeth arrangement [2]. Andrews proposed that flattening the occlusal plane should be the treatment goal in orthodontics.…”

The curve of Spee is an important characteristic in the mandibular arch. An optimal occlusion must have a curve of Spee ranging from flat to mild. Therefore, an understanding of the curve of Spee is essential for both diagnosis and treatment planning in orthodontics. The aim of this study was to examine the difference in both the form and depth of the curve of Spee among class I, II, and III malocclusions and investigate the relationship between the depth of the curve of Spee with both overjet and overbite among patients at the University of North Sumatera Dental Hospital. A total of 100 dental study models with ages older than 15 years were enrolled and divided into 5 malocclusion groups: class I (n = 40), class II division 1 (n = 32), class II division 2 (n = 10), class II subdivision (n = 7), and class III (n = 11). The depth of the curve of Spee, overjet, and overbite was measured on dental study models with a digital caliper. The depth of curve of Spee was taken as the mean measurement from both sides of the arch on dental study models. The correlation coefficient between the depth of the curve of Spee and other variables were also calculated. The results showed that a maximum mean depth of the curve of Spee of 4.65 ± 1.41 mm in the class II division 2 group and a minimum depth of 2.34 ± 0.96 mm in the class III group. A statistically significant correlation was also found between the depth of the curve of Spee with both overbite and overjet. In conclusion, the curve of Spee was found to be deepest in class II division 2 followed by class II division 1, class II subdivision, class I, and class III malocclusion.
