What is the primary goal of performing extractions where class 3 mobility is present?

The primary goal of performing extractions in the presence of class 3 mobility is to allow for future implants. When a tooth exhibits class 3 mobility, it indicates that the tooth is significantly compromised, often due to advanced periodontal disease or severe bone loss. In such cases, retaining the tooth may not only be unfeasible but can also jeopardize the patient's oral health and the surrounding teeth.

Extracting the mobile tooth creates space in the dental arch, which can then be utilized for planning and placing dental implants. Implants require a stable environment to integrate properly with the bone, and extracting a mobile tooth can be a critical first step in addressing the patient's needs for restoration. After healing, the site can be evaluated for implant placement, thereby enabling a functional and aesthetic solution for the patient.

While aspects like preventing further mobility, reducing pain, or facilitating orthodontic treatment might also be considered during extractions, the chief concern in the context of class 3 mobility is ensuring a suitable foundation for future implant placement.
