Curve of Wilson

Curve of Wilson

The Curve of Wilson is a concept in orthodontics that describes the natural curvature of the occlusal plane in the dental arch. It was first introduced by Dr. Edward H. Angle, a prominent figure in the field of orthodontics, in the early 20th century. The Curve of Wilson plays a crucial role in achieving proper occlusion and a harmonious bite.

Definition

The Curve of Wilson refers to the curvature of the occlusal plane in the transverse dimension. It is named after Dr. William James Wilson, who extensively studied the relationship between the occlusal plane and the curvature of the dental arch. The Curve of Wilson is defined as the curve that connects the buccal cusps of the posterior teeth in each dental arch.

Importance

The Curve of Wilson is essential for maintaining proper occlusion and a stable bite. It allows for the distribution of occlusal forces evenly across the dental arch, preventing excessive stress on individual teeth. This helps to minimize the risk of tooth wear, fractures, and temporomandibular joint (TMJ) disorders.

Formation

The Curve of Wilson is primarily influenced by the shape and alignment of the posterior teeth. The inclination and angulation of the teeth, as well as the intercuspal position of the mandible, contribute to the formation of the curve. The natural curvature of the dental arch, along with the Curve of Spee (a sagittal curve), determines the overall occlusal harmony.

Clinical Considerations

Orthodontists and dentists take the Curve of Wilson into account when planning and executing orthodontic treatments. They aim to achieve a harmonious occlusion by aligning the teeth in a way that follows the natural curves of the dental arch. This helps to optimize the function and aesthetics of the patient's bite.
