Kennedy Classification in Dentistry

RPD classification can be based on the type of support provided by the denture, such as tooth-supported or tissue-supported.

Besides the type of support, RPD classification also considers the location of the edentulous area, such as anterior or posterior.

The dentist's fee is not a relevant factor for RPD classification. Classification focuses on the denture's design and support, not its cost.

There are multiple methods for classifying RPDs, each based on different factors and features.

Different RPD classification methods employ various factors, like support, location, and number of edentulous areas.

Rule 7 of Kennedy classification considers the number of additional edentulous areas present in the arch, beyond the primary edentulous space.

According to Rule 8, Class IV arches have no modification areas, meaning they have no additional edentulous spaces.

The denture base of a Removable Partial Denture serves to carry the artificial teeth and distribute forces evenly onto the supporting tissues.

The primary impression in RPD construction is taken to create a custom tray that accurately fits the patient's mouth.

After taking the impression, the first laboratory step in RPD construction is to pour the impression in dental stone to create a primary cast.

The clinical steps of RPD construction involve taking a complete history, performing a thorough examination, and making a diagnosis.

The final design drawing serves as a comprehensive guide for the technician during the construction of the denture.

The final product of the RPD construction process is a custom-made denture that restores the patient's missing teeth.

The final design drawing is duplicated to create a refractory cast, which is used in the construction of the denture's framework.

Surveying initiates the RPD construction process by providing essential information about the patient's mouth, including the angles and contours.

The refractory cast is used to create the denture's framework, which provides strength and support for the restoration.

The Master Cast is created after the mouth preparation stage, as it requires accurate measurements of the prepared teeth and supporting tissues.

The primary cast, also known as the Master Cast, is primarily used to create a special tray that accurately fits the patient's mouth for subsequent impressions.

Mouth preparation, involving tooth reduction and tissue trimming, should be done before creating the Master Cast to achieve accurate measurements.

The primary cast is created from the primary impression taken during the initial assessment of the patient's mouth.

The Master Cast is made after mouth preparation because it reflects the prepared state of the teeth and tissues, crucial for accurate denture construction.

The primary cast is also known as the Master Cast, indicating its crucial role in constructing a custom tray.

Before creating the Master Cast, the mouth must be prepared, which includes tooth preparation and tissue trimming, to ensure accurate measurements.

A primary cast is made from the primary impression, which is taken to capture the shape and dimensions of the patient's mouth.

The primary cast is essential for creating a custom tray that accurately fits the patient's mouth, ensuring a precise fit for the denture.

The correct sequence of events is to prepare the mouth first, followed by making the Master Cast to achieve accurate measurements and ensure a perfect fit for the denture.
