Final answer:
In a removable partial denture, the teeth that are being replaced are the pontics, which are artificial teeth, while the teeth that support the denture are called abutments.
Step-by-step explanation:
In a removable partial denture, the teeth that are being replaced would be referred to as the pontics. The pontics are the artificial teeth that fill in where natural teeth are missing. Conversely, abutments are the natural teeth or dental implants that serve as supports for the removable partial denture, anchoring it in place. Abutments are crucial as they provide stability and retain the partial denture, while pontics are primarily for aesthetic function and to help in chewing and speaking.
During an individual's lifetime, their 20 deciduous teeth (baby teeth) begin to appear at about 6 months of age and are gradually replaced by 32 permanent teeth between approximately age 6 and 12. The set of permanent teeth consists of 8 incisors, 4 canines, 8 premolars, and 12 molars, which include the wisdom teeth that generally emerge later in adolescence or early adulthood.
