Final answer:
The Kennedy Classification system is a method in prosthodontics to categorize edentulous areas for partial denture design.
Step-by-step explanation:
The Kennedy Classification is used in prosthodontics to classify edentulous areas within the mouth that may require partial dentures. An edentulous area is a region in the mouth where teeth are absent.
The Kennedy Classification takes into account the number and position of these edentulous areas in order to aid in the design and planning for removable partial dentures (RPDs).
Here is a brief overview of the tooth emergence stages in the human lifespan:
Deciduous teeth, also known as baby teeth, typically start to emerge at about 6 months of age and continue until about 2 to 3 years of age.
Permanent teeth generally start to replace deciduous teeth around 6 years of age and this process goes on until the early teenage years.
The third molars, commonly known as wisdom teeth, usually emerge later in adolescence or early adulthood, roughly between 17 and 25 years of age.
Deciduous teeth emerge around 6 months to 2-3 years, permanent teeth from around 6 years to early teens, and wisdom teeth from about 17 to 25 years of age.
So, the partial denture design edentulous areas determine the kennedy classification.
