Historically, when a patient’s dental condition reached a state of total tooth loss, treatment was limited to a complete denture with no hope of improving that status. The Kennedy method of classification of Edentulous Spaces was originally proposed by Dr. Edward Kenedy in 1925. USA.gov. There are two more Classes added to Kennedy’s classification which are –, Base on the changes which are required due to missing teeth the clases are further divided into Modifications which are –. It is quite interesting that the same problem is seen in Deer as well. Kennedy divided all partially edentulous arches into four main types. J Prosthodont. Class 1 arches being the most common and class 4 being the least common. RULE 3: If a third molar is present and is to be used as an abutment, it is considered in the classification. The classification of RPDs and partially edentulous arches simplifies communication and discussions. However a universally acceptable classification system which helps in visualization, communication and plan treatment for such situation is an ideal goal. Introduction.

This system was further defined and expanded upon by Dr. O.C. CLASS II : A unilateral edentulous area located posterior to the remaining natural teeth. PARTIALLY EDENTULOUS patients exhibit a wide range of physical variations and health conditions. The meaning Cross Arch stabilization means creating a retainer on the opposite side of the arch from where the missing teeth are to stabilize the appliance from biting and chewing forces. what is cross arch stabilization in simple words. Edentulous spaces which are not going to be restored with the RPD are not considered in the classification of the arch. These guidelines may help practitioners determine appropriate treatments for their patients. Clipboard, Search History, and several other advanced features are temporarily unavailable. Four categories are defined, ranging from Class I to Class IV, with Class I …. This prevents the teeth which have been replaced from being lifted when you start to chew as the retainer on the opposing arch creates a counter balance. (adsbygoogle = window.adsbygoogle || []).push({}); Kennedy’s method of classifying the Edentulous arch is one of the simplest and most used classification systems because of the ease at which it can be discussed with others as it brings immediate visualization of the partially edentulous arch. The American College of Prosthodontists has developed a classification system for complete edentulism … NIH 1 ICK CLASSIFICATION SYSTEM FOR PARTIALLY EDENTULOUS ARCHES SULIEMAN S.

The length of the edentulous space, i.e. What is the current thinking as to the cause in humans of these lesions? RULE 5: The most posterior edentulous area (or areas) always determines the classification. Initial preprosthetic treatment and/or adjunctive therapy can change the initial classification level. eCollection 2020 Apr. Tasaka A, Uekubo Y, Mitsui T, Kasahara T, Takanashi T, Homma S, Matsunaga S, Abe S, Yoshinari M, Yajima Y, Sakurai K, Yamashita S. BMC Oral Health. The American College of Prosthodontists has developed a classification system for complete edentulism based on diagnostic findings. Class II – An arch with two free-end denture bases. This system was further defined and expanded upon by Dr. O.C. edentulous spaces when classifying the arch. None of these classification systems include implants, simply because most of them were proposed before implants became widely accepted. The current and future treatment of edentulism. I read your older post on the Differences between Fenestration and Dehiscence. Evidence-based guidelines for the care and maintenance of complete dentures: a publication of the American College of Prosthodontists. 3.

Classification system for completely edentulous patients The American College of Prosthodontists (ACP), has developed a classification system for complete edentulism based on diagnostic findings. Each class is differentiated by specific diagnostic criteria. Diagnosis, Risk Assessment, and Implant Treatment Indications Prosthetic rehabilitation of the edentulous maxilla is known to be challenging and requires meticulous planning. Felton D, Cooper L, Duqum I, Minsley G, Guckes A, Haug S, Meredith P, Solie C, Avery D, Chandler ND; American College of Prosthodontists; Academy of General Dentistry; American Dental Association Council on Scientific Affairs; American Dental Hygienists' Association; National Association of Dental Laboratories; GlaxoSmithKline Consumer Healthcare. At this time, there is no classification system for partially edentulous arches incorporating implants placed or to be placed in the edentulous spaces for a removable partial denture (RPD). The most posterior edentulous space determines the class of the arch for Classes I through IV. Classification of Completely Edentulous Arches • The edentulous jaw is divided into three regions and described according to the Misch–Judy classification. RULE 7: The extent of the modification is not considered, only the number of additional edentulous areas. The Kennedy classification divides partially edentulous arches into four classes. CLASS III: A unilateral edentulous area with natural teeth remaining both anterior and posterior to it. 2019 Jan-Mar;19(1):88-92. doi: 10.4103/jips.jips_252_18. 1 (I-1): a completely edentulous maxilla opposed by the partially edentulous mandible with preserved anterior teeth only. 4 The presence of TMD symptoms raises the classification by 1 or more levels in Class I and II patients. and functional challenges related to their arch morphology, resorptive patterns, quantity and quality of the bone, presence of anatomical structure, and biomechanics.3 When a clinician is planning the rehabilitation of an edentulous patient, he/she should realize that the edentulous maxilla and mandible pose different challenges.
