Cummer's Kennedy's, Applegate's, Neurohr, Bailyn, Wild, Skinner,7 Kennedy's classification are most commonly used and widely accepted because they provide immediate visualization. Applegate has provided the following eight rules governing the application of the Kennedy method. The implant dentistry bone volume classification developed by Misch and Judy in 1985 may be used to build on the four classes of partial edentulism described in the Kennedy-Applegate system. State of return requested to the laboratories 42 7. The stability of the prosthesis is maintained by counterresisting the occlusal forces exerted on the restored arch-curve by use of a posteriorly directed path of placement for the prosthesis. The implant dentistry bone volume classification developed by Misch and Judy in 1985 may be used to build on the four classes of partial edentulism described in the Kennedy–Applegate system. Ulmer FC Jr. PMID: 6577289 [PubMed - indexed for MEDLINE] Unilateral Bounded Saddle. Slight modification of Kennedy classification Class I of this classification is Kennedys Class II and Class II is Kennedys Class I.

What is the Kennedy classification of the partial denture below? These modifications are developed by Dr. O.C. Results: Class III dental arch was the most dominant pattern with class IV being the least in number. Kennedy-Applegate classification of partially edentulous dental arches. * Rule 2 If a third molar is missing and not to be replaced, it is not considered in the classification.

KENNEDY CLASSIFICATION SYSTEM RULES (Proposed by Dr. O.C. 1. The extent of the modification is not considered. Applegate also provided the following 8 rules to govern the application of the Kennedy system: Rule 1: Classification should follow rather than precede extractions that might alter the original classification. Result was another descriptive classification without much contribution to the problem Swenson's Classification. Class III Mod I. Class 2: Teeth are present only on one side of the fracture line. Rule 7 states that extent of the modification is not considered; only the number of edentulous areas is considered. He added two more classifications (Class V and Class VI) to develop a new classification named “Kennedy–Applegate classification”. This classification was given by Kazanjian and Converse by considering the presence of Teeth in relation to the fracture line. What is Kennedy Classification Class II? Class 1: Teeth are present on both sides of the fracture line. It was based on visual examination of the selected subjects for determining the pattern of the partial edentulism according to Kennedy’s Classification System with Applegate's modification rules. What is the Kennedy classification of the partial denture below? Kennedy’s class IV was the least encountered one with 43 (2.9%) in maxilla and 57(3.8%) in mandible. Class II Mod I. Kennedy classification is governed by the most posterior edentulous area that is being restored. Class II Mod I. Anterior Bounded Saddle. Unilateral edentulous area present posterior to remaining natural teeth. However, he too concluded that bilateral edentulous ridges are the most frequently occurring situations that too in the mandible. The extent of the modification is not considered. Edentulous areas with no teeth replacements are not considered 3. Classification follows all mouth preparations including extractions 2. Kennedy’s Class III modification 1 was the most common modification encountered and location of modification was mostly involved posterior areas. Bilateral edentulous area present posterior to remaining natural teeth. Posterior modification area 4. roll no. Class-II: Free-end saddle on one side only. Kennedy Class IV does not have a modification because if it does it will be classified as one of the other classes. These cause the most difficulty in providing dentures as there is no help from any distal teeth for retention and stability. If there is one extra edentulous space it is classified as Modification 1. Kennedy-Applegate Classification Class IV- A single but bilateral (crossing the midline) ... Class I- Bilateral edentulous areas located posterior to remaining natural teeth Additional edentulous areas are " modification spaces" Kennedy Class II Modification I . The Kennedy classification proposed by Dr. E. 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. Easy explanation for the Kennedy Classification and Applegate's Rules for removable partial dentures. Mandibular arch had 2nd premolar, lateral and central incisor in right quad rant. Rule 3: applegate's rules. Widely accepted Kennedy Applegate classification does not give any idea about length, span or number of teeth missing. Third molars are not considered unless present or being replaced 4. Kennedy Class I RPDs are fabricated for people who are missing some ... which replacement teeth are being placed are further classified with modification states that were defined by Oliver C. Applegate. Intra orally the patient was Kennedy's class I modification 1 in upper arch and class 1 modifi cation 2 in lower arch. edentulous areas other than those determining the classification. The Kennedy classification with the guidelines advocated by Applegate for each partially edentulous arch was recorded.19,20 Categorization of the modifications for the Kennedy RPD classes was expanded to five categories: 1. RULE 2: If a third molar is… partial dentulism and Kennedy’s class III without modification span was the most common pattern of partial dentulism in maxilla 569(37.9%) and in mandible 462(30.7%).

Applegate) 1. It is postulated that in Applegate-Kennedy class V partially edentulous situations, the remaining anterior teeth in the maxilla should not be used as abutments for removable partial dentures. In left quadrant central incisor and 1st premolar were present.

Kennedy classification is governed by the most posterior edentulous area that is being restored. Like the Bailyn classification and also the Skinner classification, it is to classify the partially edentulous arch in a manner that will suggest certain principles of design for a given situation. 3.
