Figure 2. The material studied was obtained from cadavers. The most common type of ridge is the Class I type which constitutes to about 32.4% of the edentulous ridges. The dentist who wishes to help his edentulous patient should seek to be sensitive to all these variables, and to understand and treat that unique combination of factors which exists in that patient. Natarajan Kalavathy, Nikhil Anantharaj, Ankita Sharma, Tanuj Chauhan, Effect of serum vitamin D, calcium, and phosphorus on mandibular residual ridge resorption in completely edentulous participants: A clinical study, The Journal of Prosthetic Dentistry, 10.1016/j.prosdent.2020.07.019, (2020). The lining of the edentulous ridge adjacent to the teeth under the saddle of the prosthesis is inflamed. In dentistry, numerous types of classification schemes have been developed to describe the teeth and gum tissue in a way that categorizes various defects. This alveolar ridge is a class III ridge according to the classification presented in the article. Connectors may be fixed or movable. The most difficult to manage is the Class III type Edentulous ridge which has loss of both height and width of alveolar bone, it is most commonly seen in patients with Chronic Periodontal conditions which has lead to the loss of teeth in said region. With Implants gaining popularity, the width of the bone in Bucco-lingual direction and the height of bone available plays a major role in deciding the success of Implants and also in deciding the type of Implant to be used. The prosthodontist encounters increasing problems in the fabrication of a well functioning complete denture over a resorbed edentulous ridge. The shape, size and the type of bone in the Partial Edentulous Ridge will in turn, affect the type of prosthodontic treatment needed to replace the missing teeth. It divides the mandible into the anterior, interforaminal region and posterior areas located distally of the mental foramina. If the ridge is narrow, then it may not provide adequate support for a denture.

Substantially Compromised Edentulous Area • Any posterior maxillary or mandibular span that is greater than 3 missing teeth or 2 molars • Any edentulous span including anterior and posterior areas of 3 or more missing teeth Severely Compromised Edentulous Area 4 … We can get good Retention and resistance without much effort in this … In the third division, Other conditions impacting the periodontium, there can be again further breakdown. If the variable change in any given patient, the rate of RRR may change. Additionally, of paramount importance that dictates the types of procedures, material selection and ultimately success of implant surgery is the quality and quantity of the edentulous ridge. Background: The prevalence of the condition where one edentulous arch opposes a natural or restored dentition is quite common. It provides 3 primary parts: In Periodontal wellness, gingival illnesses and conditions, there are usually 3 sub-types, I) Periodontal wellness and gingival wellness, a. Gingival wellness on an intact periodontium, c. Gingival health on a decreased periodontium, a. To organize treatment plans in a consistent approach, a classification of patient conditions is necessary. – The y are commonly used in a custom tray for the fi nal impression for a complete denture. (6) Both osteoid and necrotic bone types were observed.

Endocrine, nutritional and metabolic illnesses, In the 2nd component of the brand-new classification system, Periodontitis, there are once again 3 sub-types, III) Periodontitis as a symptoms of systemic illness. INTRODUCTION, CLASSIFICATION & BIOMECHANICS OF PARTIALLY EDENTULOUS ARCHES. The festoon contour of the prosthesis around adjacent teeth is a bacterial plaque retention factor causing loss of periodontal attachment, 5 mm deep pocket formation, and bleeding on sounding. Prosthetic/periodontal interrelationships Compend Contin Educ Dent. Resorption is exacerbated by pressure on the bone; thus, long-term complete denture wearers will experience more drastic reductions to their ridges that non-denture wearers. 2. Most laboratory prescription forms will give you the option to select one of four types of pontic shapes. Location and extent of the edentulous area(s) 2. The following procedures were considered: a) Guided bone regeneration (GBR); 2) Onlay bone grafts; 3) Inlay grafts; 4) Bone splitting for ridge expansion (RE); 5) Distraction osteogenesis (DO); and 6) Revascularized flaps. In Hye Lee, Young Bum Park, Dong-Hoo Han, Titanium-zirconium alloy narrow-diameter implants for the rehabilitation of horizontally deficient mandibular posterior edentulous ridges, The Journal of Korean Academy of Prosthodontics, 10.4047/jkap.2017.55.2.212, 55, 2, (212), (2017).
