Evaluation depth of the curve of Spee in class I, class II, and class III malocclusion: A cross sectional study.
Evaluation of skeletal and dental parameters in individuals with variations in depth of Curve of Spee.
Investigation Of Variation In Curve Of Spee, Over Jet and Overbite Among ClassI And Class-II Malocclusion Subjects And To Find Sexual Dimorphism, If Any.
Correlation between curve of spee and vertical eruption of anterior or posterior teeth in class II division I.
DISCUSSION: The Broadrick flag is a useful tool in prosthodontic and restorative dentistry, as it identifies the most likely position of the centre of the curve of Spee.

Results: Mean depth of Curve of Spee in class I malocclusion was 2.
Conclusion: The curve of Spee was deepest in class II div 2 malocclusion.
Ferdinand Graf Von Spee1 found in the dentition of other mammals and fossil humans,2a line of occlusion, which was termed as curve of Spee and was described in humans in the late 19th century.
1 In 1890 Ferdinand Graf Von Spee2 defined a line of occlusion by using skulls with abraded teeth which is now termed as curve of Spee (COS).
A possible explanation for the development of the curve of Spee is the earlier eruption of mandibular permanent teeth before maxillary counterparts.
In deciduous dentition the COS is suggested to range from flat to mild whereas curve of Spee in permanent dentition tends to be deeper.
Key Words: Curve of Spee, Vertical eruption, Class II Division 1.
The Curve of Spee (COS) is curve of occlusion and defined as the line on a cylinder tangent to the anterior border of the condyle, the occlusal surface of the mandibular second molar, and the incisal edges of the mandibular incisors.
Therefore, the objective of this study was to investigate the relationship of the depth of the COS with the vertical eruption of anterior and/ or posterior teeth, and also difference between right and left side COS in Class II Division I malocclusion aiming to contribute to the knowledge about the development of Curve of Spee.
