The minimum thickness of 1.5 mm for minor removable partial denture (RPD) connectors is significant because it provides an adequate strength and stability while minimizing the risk of distortion or fracture during normal use. Minor connectors serve as the critical link between the major connector and the other components such as clasps or other attachments that aid in the support and retention of the prosthesis.

Selecting a thickness that is too thin may lead to a failure in maintaining the integrity of the connector under functional stresses, which could compromise the entire prosthetic framework. Hence, a thickness of 1.5 mm is considered a balanced compromise, offering durability while also ensuring the comfort of the patient. This thickness helps in achieving successful transmission of forces during mastication and prevents any potential discomfort that might arise from a structurally inadequate connector.
