Wax rims are devices that are used in dentistry to help in the fabrication of removable prostheses, such as complete and partial dentures.

Dentistry branch of medicine

Dentistry, also known as Dental and Oral Medicine, is a branch of medicine that consists of the study, diagnosis, prevention, and treatment of diseases, disorders, and conditions of the oral cavity, commonly in the dentition but also the oral mucosa, and of adjacent and related structures and tissues, particularly in the maxillofacial area. Although primarily associated with teeth among the general public, the field of dentistry or dental medicine is not limited to teeth but includes other aspects of the craniofacial complex including the temporomandibular joint and other supporting, muscular, lymphatic, nervous, vascular, and anatomical structures.

Dentures prosthetic devices constructed to replace missing teeth

Dentures are prosthetic devices constructed to replace missing teeth, and are supported by the surrounding soft and hard tissues of the oral cavity. Conventional dentures are removable. However, there are many denture designs, some which rely on bonding or clasping onto teeth or dental implants. There are two main categories of dentures, the distinction being whether they are used to replace missing teeth on the mandibular arch or on the maxillary arch.

A removable partial denture (RPD) is a denture for a partially edentulous patient who desires to have replacement teeth for functional or aesthetic reasons and who cannot have a bridge for any reason, such as a lack of required teeth to serve as support for a bridge or financial limitations.

When placed in the mouth, wax rims allow the dentist to record a measured vertical dimension of occlusion (VDO) because the patient will be unable to close further than the wax will allow. The wax is built up or removed until the appropriate VDO has been established. The rims are then notched in order to allow an index of the relationship of the maxillary rim to the mandibular rim with an impressionable medium, such as Alluwax or Regisal.

Vertical dimension of occlusion

Vertical dimension of occlusion, or VDO, also known as occlusal vertical dimension (OVD), is a term used in dentistry to indicate the superior-inferior relationship of the maxilla and the mandible when the teeth are occluded in maximum intercuspation.
