Class I: Bilateral space with no teeth posterior to it. Class II: Bilateral space with teeth present posterior to one space. Class III: Bilateral space with teeth present posterior to both spaces. Class IV: Unilateral space with no teeth posterior to it.
What is Kennedy classifications?
Kennedy Classification Summary Class I – posterior, bilateral free-end saddles. Class II – posterior, unilateral free-end saddle. Class III – posterior, unilateral bounded saddle. Class IV – anterior bounded saddle.
Which of the following Kennedy classes of removable partial denture are tooth borne?
Unlike Class I and Class II RPDs which are both tooth-and-tissue-borne (meaning they both clasp onto teeth, as well as rest on the posterior edentulous area for support), Class III RPDs are strictly tooth-borne, which means they only clasp onto teeth and do not need to rest on the tissue for added support.
What are the parts to a removable partial denture?
Generally speaking, any removable partial denture includes the following components: the saddle, direct retainers, indirect retainers, connectors, and incisal and occlusal rests. Each of these components helps the denture work efficiently within the mouth.
What is a contraindication to partial dentures?
Contraindications for a Removable Partial Denture: A lack of suitable teeth in the arch to support, stabilize, and retain the removable prosthesis. Rampant caries or severe periodontal conditions that threaten the remaining teeth in the arch. A lack of patient acceptance for esthetic reasons. Chronic poor oral hygiene.
How many types of removable partial denture are there?
There are 3 types of removable partial dentures: acrylic tissue-supported dentures, dentures with cast metal frameworks en dentures with cast metal frameworks and (semi)precision attachments.
What is the best type of partial denture to get?
Cast Metal Partial Dentures
- Cast metal partial dentures are the most-used option when it comes to partials because they’re strong and they’re built to last many years.
- While less sturdy than cast metal partial dentures, flexible partial dentures are valued for their comfort and flexibility.
What is the purpose of Kennedy classification?
Kennedy’s classification provides immediate visualization, prosthesis support and design features for removable partial denture. Dietary intake and nutritional status is affected by poor oral hygiene and loss of teeth.
Why Kennedy’s classification is widely used than the other classification?
Kennedy is the most widely accepted and used classification method due to its simplicity and ease of application, with nearly 65,000 possible combinations of partially edentulous arches.
What is a removable partial denture in dentistry?
A removable partial denture or bridge usually consists of replacement teeth attached to a pink or gum-colored plastic base, which is sometimes connected by metal framework that holds the denture in place in the mouth. Partial dentures are used when one or more natural teeth remain in the upper or lower jaw.
What is rule 1 of the denture classification rule?
Rule 1: Classification should follow rather than precede any extractions of teeth that might alter the original classification. All extractions that are required needs to be completed before planning a partial denture because extractions in the posterior region could alter the classification.
What is Kennedy’s classification of partially edentulous arch?
Kennedy’s classification is so far the easiest and widely used classification for partially edentulous arch. The classification is based on the relationship of edentulous arch to the adjacent abutment teeth. They are classified as follows: Kennedy Class I: Bilaterally located edentulous spaces, posterior to natural teeth.
How are partial dentures designed?
The partial denture is designed as follows: Direct retention: Kennedy Class I dentures are generally tooth and tissue supported. They get retention from the tissue as well as the abutment teeth. Clasps: two retentive clasps are placed on each abutment which is always the last tooth near the edentulous space.
What is Kennedy’s Class I?
Kennedy’s classification is so far the easiest and widely used classification for partially edentulous arch. The classification is based on the relationship of edentulous arch to the adjacent abutment teeth. Kennedy Class I: Bilaterally located edentulous spaces, posterior to natural teeth.
