Background: The restoration of mastication is an element of the therapeutic success of the removable prosthesis. The aim of this study was to evaluate the chewing time of subjects wearing a metallic removable partial denture (MRPD) restoring a distal extension edentulism. Materials and methods: This is a descriptive pilot study carried out after a review of patient records. Subjects were asked to chew test foods, carrots and peanuts. Chewing was to continue until they perceived that the bowl was fit to be swallowed. All sequences were videotaped and data on the duration of the chewing sequence of the test foods was recorded on an Excel® spreadsheet. Data analysis was performed using SPSS® version 23 software with a 5% risk of error. Results: Out of a sample of 17 MRPD wearers, 12 subjects had a toothless Kennedy class I and 5 subjects had a Kennedy class II edentulism condition with 9 females (53%) and 8 males (47%). Subjects between 46 and 65 years of age were in the majority with a percentage of 59%. After chewing the sampled bowls, Kennedy class I edentulous subjects had an average chewing time of 93.24 seconds ± 31.93 for peanuts and 109.18 seconds ± 53.35 for cores. The respective averages of the class II edentulism subjects were 127.53 seconds ± 62.84 and 128.95 seconds ± 73.35 for peanuts and carrots respectively. Conclusion: This study reveals that peanut chewing is easier and the subjects with MPD restoring a class I edentulism performed less time than those with class II edentulism, a fact related to the presence of changes in class II edentulism. Statistically, no significant correlation was found between carrots or peanuts chewing and type of distal extension MRPD wearers.

Even though dental attachments have a long successful history, many of the dental practioners are unaware about its benefits in daily clinical practice. It highly improves the comfort, aesthetic, function and patient satisfaction, especially in the patients with long span edentulism where implants and fixed partial denture (FPD) are not indicated and cast partial dentures are barely satisfactory. This case report describes the clinical and the laboratory steps for prosthetic rehabilitation of a patient with maxillary distal extension partially edentulism with cast partial denture using Preci Vertex attachments.

The aim of this study is to demonstrate the use and the effectiveness of cephalometry and golden proportions analysis of the face in planning prosthetic treatments in totally edentulous patients. In order to apply this method, latero-lateral and posterior-anterior X-rays must be performed in addition to the common procedure. Two main concerns for totally edentulous patients are the establishment of the vertical dimension and the new position of the occlusal plane. The divine proportion analysis was carried out by the use of a golden divider. The prosthetic protocol was divided into three steps and a case was selected for better understanding. Referring to the golden relations, if the distance from the chin to the wing of the nose is 1.0, the distance from the nose to eye is 0.618. This proportion is useful and effective in determining the correct prosthetic vertical dimension. The incisal margin of the lower incisor must be positioned between Point A (A) and protuberance menti (Pm) according to the gold ratio 0.618 of the total height A-Pm. Posteriorly the occlusal plane must be placed 2 mm below the divine occlusal plane (traced from the incisal margin of lower incisors to Xi point). A prosthesis made in accordance with cephalometric parameters and divine proportions of the face helps to improve the patient’s aesthetics, function and social personality.

Abstract Background Implant-supported removable partial dentures (ISRPDs) are an effective treatment for partially edentulous patients. ISRPDs improve patients’ satisfaction and oral function to a greater extent than RPDs by improving denture stability and enhancing support. However, the effect of a type of direct retainer on displacement of the abutment teeth and dentures in ISRPDs remains unclear. Therefore, we made a resin mandibular model of unilateral mandibular distal-extension partial edentulism for mechanical simulation and compared the dynamic behavior of the abutment teeth and the denture base among different tooth-borne retainers with various rigidities for RPDs and ISRPDs. Methods A resin mandibular model for mechanical simulation that had unilateral mandibular distal-extension edentulism and was missing the first molar, second molar, first premolar, and second premolar, and a denture fabricated from the patient’s computed tomography images were used. Three types of direct retainers with different connecting rigidities were evaluated. The vertical displacement of the denture base and buccal and lingual sides and the mesial displacement of the abutment teeth were measured. Results Regardless of the rigidity of the direct retainers and loading positions, the displacement of the denture bases in the ISRPDs was significantly smaller than that in the RPDs (P < 0.001). There was no significant difference in vertical displacement of the denture bases among direct retainers with various connecting rigidities in the ISRPDs. Conversely, horizontal displacement of the abutment teeth in both the RPDs and ISRPDs tended to be larger with the cone crown telescope, which has high rigidity, than with the cast cingulum rest and wire clasp, which have much lower rigidities. Conclusion Our results suggested that cast cingulum rest and wire clasps as direct retainers are appropriate ISRPDs to minimize denture movement and suppress displacement of the remaining teeth in patients with unilateral mandibular distal-extension partial edentulism.

Proper Orientation

Impression making is not only important but is also the most significant step in the fabrication of any fixed or removable prosthesis. Proper impression making may be hindered by certain pathologic conditions. Reduced mouth opening is one of the common mechanical obstructions for proper orientation of the impression tray in the patient’s mouth. In patients with trismus induced by submucous fibrosis, the procedure may be even more difficult to carry out because of reduced tissue resiliency and obliteration of vestibular spaces. Use of sectional trays offers one of the alternatives to overcome the problem of restricted mouth opening. Fabrication of customized impression trays according to the patient dentition improves the accuracy of impression making. The present case reports describe the fabrication of sectional custom trays designed for dentulous patients with chronic tobacco-induced submucous fibrosis.

Objectives: The purpose of this study was to evaluate vertical alveolar bone loss 3 months after tooth extraction when a technique of ridge preservation was applied using a particulate demineralized freeze-dried bone allograft 300 - 500 µm associated with platelet concentrates (platelet-rich-fibrin) in the form of gel and membranes. Material and Methods: A retrospective radiological clinical study was conducted on 56 patients for whom 95 extractions had been performed immediately followed by alveolar filling. Among the patients, 17 were smokers and 16 were provided with an immediate removable temporary prosthesis after extractions. Vertical bone loss was measured radiologically by panoramic X-ray before extractions and by a computed tomography scan 3 months after, at the level of mid-buccal bone wall, by two independent observers. For statistical analysis, Student’s t-test was performed to compare the mean bone loss between mono- and pluri-radicular teeth and to compare the mean bone loss between tobacco users versus non users and finally to compare the mean bone loss between individuals that had provisional removable prosthesis and those that had not. Results: Three months after tooth extraction, the mean of vertical loss of the mid-buccal bone wall was 0.72 (SD 0.71) mm (5.53% SD 5.19). No significant difference between bone loss at mono-radicular and pluri-radicular teeth (P = 0.982) was observed. There was no significant correlation between tobacco habits and bone loss (P = 0.2), nor between provisional removable prosthesis and bone loss (P = 0.786). Conclusion: These results indicate a good potential for the technique using Demineralized Freeze-Dried Bone Allograft 300 - 500 µm and platelet concentrates in alveolar bone preservation.
