Abstract Objective The aim of this study was to assess the evolution of chewing force in edentulous geriatric patients rehabilitated with complete dentures. Chewing function is compromised in individuals who lose all their teeth, as well as in those with complete dentures. The maintenance and recovery of the chewing function in these patients require replacement of the lost natural teeth. Materials and Methods In this study, the chewing force was evaluated by electromyographic analysis of the temporalis and masseter muscle endings in 120 patients with old and new bimaxillary complete dentures. Results Replacement of complete dentures was shown to improve stability, retention, occlusion, and support of the prosthesis. All jaw movements were evaluated using electromyography to assess the evolution of chewing force with and without occlusal adjustment, identify premature contact points, identify occlusal interference, respect the balanced occlusal scheme, and assess the increase in muscle strength. This study found that muscle strength in patients with prosthesis without occlusal adjustment was 527.1 N but was higher for prostheses with occlusal adjustment at 614.7 N, and this strength of 614.7 N was maintained after 1 month of control. Conclusion The chewing force evolved in patients with complete dentures, and an increase was observed when occlusal adjustment was performed.

One of the existing methods for analysis of the vertical dimension of occlusion or occlusal face height is the cephalometric analysis of the distance from nasion to menton (N-Me). The vertical dimension of occlusion was measured in 30 lateral cephalometric radiographs of edentulous patients (experimental group), with models of complete dentures after clinical methods of determining the vertical and horizontal intermaxillary relation and 30 lateral cephalometric radiographs of participants with natural teeth (control group). The aims of the present study were: to analyse the vertical dimension of occlusion in participants with natural teeth skeletal class I, to cephalometrically evaluate the reconstructing vertical dimension of occlusion of edentulous patients skeletal class I , to compare examined variables between individuals with natural teeth and edentulous patients. The results indicated a remarkable correlation in the vertical dimension of occlusion established initially for the edentulous patients when compared with the measurements made for dentulous patients. The results showed the vertical dimension of occlusion span a range between 106,7 - 138 mm (X _ =122,24) in subjects with natural teeth. In edentulous patients the values of vertical dimension of occlusion span ranged between 109,8 - 141,6 mm (X _ =122,46). The vertical dimension of occlusion in male participans was increased in the group of persons with natural teeth as well as in edentulous patients. The results of t-test proved that there were no statistically significant differences in examined variables between persons with natural teeth and edentulous patients (p>0,01).

ABSTRACT Objectives A combination of the neutral zone and the polished surface impression techniques is a useful method to reserve the functional and physiological forms of the underlying mandibular residual ridge by enhancing both retention and stability in Malaysian geriatric patients (2-year clinical study). Materials and methods A total of 25 Malaysian geriatric patients have participated in the current study. Two sets of dentures were served to the patients. The first set was constructed according the conventional method of complete denture construction whereas the second set was constructed by using neutral zone and polished surface impression techniques. Results The patients were followed up for 2 years and the obtained results showed that all patients have stopped using the conventional dentures and continued with the test dentures. The comparative analysis exhibited significant difference (p < 0.05) in favor of test dentures. Conclusion Combination of the neutral zone and the polished surface techniques can impart a physiological reservation to the underlying residual ridge without changes. Statement of problem It is common for completely edentulous geriatric patients to have resorbed mandibular residual ridge because of the process of aging. Some surgical interactions are contraindicated for this age group of patients, so, neutral zone technique and/or polished surface impression verified effective in improving stability for lower complete dentures. In spite of the fact that the above mentioned methods often used to enhance stability of complete denture, most of the studies were relying on only one of those methods to improve stability rather than retention. Researcher hypothesis stated that a combination of the neutral zone and the polished surface impression techniques should be performed together to enhance both stability and retention and henceforth reservation of the residual ridge under mandibular complete dentures issued to the patients with a constant follow-up for two consecutive years.

The convexity angle of facial bone structures ( N-A: A-Pg) expresses the sagittal protrusion of the maxillary part of the face compared to facial profile (the convex or concave face).The convexity angle is defined as the angle colligated by the lines N-A and A-Pg. The aims of the present study were: to analyse the convexity angle in participants with natural teeth skeletal class I, to cephalometrically evaluate the reconstructing angle of hard facial profile structures of edentulous patients skeletal class I, to compare examined variables between individuals with natural teeth and edentulous patients. The control group consisted of 30 lateral cephalometric radiographs of participants with natural teeth skeletal class I. The experimental group consisted of 30 lateral cephalometric radiographs of edentulous patients, with models of complete dentures after clinical methods of determining the vertical and horizontal intermaxillary relation. Analysis of the convexity angle was done in cephalometric radiographs by Downs metod. The results showed the facial bone structure convexity angle span a range between -13? and 10? (X= 0.45?) in subjects with natural teeth. In edentulous patients the values of facial bone structure convexity angles span a range between -5? and 10? (X=1.7?). The results of t-test proved that there were no statistically significant differences in examined variables between persons with natural teeth and edentulous patients (p>0.05). The conclusion is that clinical methods of determining the sagittal protrusion of the maxillary part of the face against the facial profile of edentulous patients used in the designing procedures of complete dentures were reliable enough in reconstruction of examined angles of hard facial profile structures.

Caring for the geriatric edentulous patients is challenging, as it requires a holistic approach, which addresses both the physical as well as the psychological aspects of such patients. Considering the increase in number of elderly individuals, the clinician should have adequate patience and understanding of psychological and emotional factors to tactfully deal with their problems. The appraisal of psychology and mental attitude for the overall success of complete denture rehabilitation is well recognized. Although important, these aspects are ignored occasionally, which is one of the major reasons for the failure of adequately constructed complete dentures. This article provides a comprehensive review of relevant literature on the mental attitudes and personality of geriatric patients and highlights the necessity of considering these factors for the overall success of complete denture treatment.

(1) Background: This study aimed to investigate maximum bite force (MBF) in elderly patients with natural full dentition (FD), patients rehabilitated with Traditional Complete Dentures (CD), with overdentures (IRO) and edentulous patients (ED). We also tested whether MBF changes are associated with gender, age of the patients and body mass index (BMI) as result of altered food; (2) Methods: Three hundred and sixty-eight geriatric patients were included. We studied two types of prostheses: (a) IRO with telescopic attachments. (b) CD (heat polymerized polymethyl methacrylate resin). The MBF was measured using a digital dynamometer with a bite fork; (3) Results: We found that MBF is higher in males than females, regardless of teeth presence or absence (p < 0.01). In patients with CD or IRO, there are no differences between males and females; prostheses improve MBF compared to edentulous patients (p < 0.0001) and this effect is greater with IRO prostheses (p < 0.0001); the chewing force of FD subjects remains greater (p < 0.0001); there are no differences among chewing strength based on different BMI categories, although FD subjects have a reduced incidence of obesity; there is a significant negative correlation between MBF and age (p = 0.038; R = 0.145), and no correlation between MBF and BMI; (4) Conclusions: This study showed that MBF improves more in patients using IRO prostheses, although not reaching the MBF of FD subjects. MBF does not correlate with BMI, although we found increased percentages of obesity in edentulous subjects or those with prostheses. Thus, old people wearing prostheses require special attention by a nutritionist to avoid risk of malnutrition.

ABSTRACT A basic concern of edentulous patients is retention of their dentures. This has led to considerable experimentation and research in efforts to perfect dentures that compensate for the loss of natural teeth. The use of multiple miniature suction cups made from a soft material lining the denture satisfies the requirements of retention and stability. A technique describing the fabrication of a maxillary and mandibular multicup dentures which are more beneficial than conventional complete dentures is discussed below with case report.

AbstractA practical approach to rehabilitate the edentulous patients to optimal occlusion is not an easy task. Complete denture prosthesis when compared to natural teeth have relatively unstable bases and have no proprioception comparable to the periodontal ligament of the natural tooth and acts as the single unit instead of an individual tooth. To enhance the stability of the complete dentures, the philosophy of the balanced occlusion has been proposed. Balanced occlusion in dentures implies occlusal contacts that contribute to equilibrium of the denture bases on their respective ridges.The search for the ideal occlusal scheme, one which provides stability, comfort, function and esthetics is still underway. While there is little research to support one occlusal scheme over the other, it is known that the prosthesis is less efficient than natural teeth and the ability to chew with it varies with the individual, regardless of the occlusal schemes. Poor oral awareness makes it more difficult for a patient to adapt to the function with the prosthesis especially one with a complicated occlusal scheme. This article reviews several occlusal schemes, their characteristics, recommendations for usage along with their advantages and disadvantages.

ABSTRACT Treatment of partially edentulous patients with few remaining teeth is very challenging. These cases can be successfully treated with natural teeth supported overdentures. Comprehensive treatment plan with natural teeth supported overdentures saves the proprioceptive response of the teeth, along with other benefits such as improved masticatory efficiency, better retention, stability, support as compared to conventional tissue supported complete dentures. The other most important benefit of overdentures is the psychological security of well retaining dentures which increases patient's confidence level. This article presents a case report in which a partially edentulous patient was successfully rehabilitated with comprehensive treatment of maxillary natural teeth supported overdenture with locator attachment (Zest Anchors) and mandibular partial denture.

Abstract Background This study aimed to evaluate the effect of mandibular complete dentures relining using soft relining material on the distribution of various occlusal forces using T-Scan system. Fifty completely edentulous patients having their conventional complete dentures earlier fabricated and utilized were selected for this study. Patients were controlled diabetics, characterized by having their residual alveolar ridges moderately developed and lined with firm mucoperiosteum. Mandibular complete dentures were relined with soft denture liner and T-Scan device was used for occlusal force distribution measurement prior to denture relining and three months thereafter the relinning procedure. Results Comparison between occlusal forces percentages before and after denture relining revealed that occlusal forces percentages was significantly lower after denture relining in anterior area, significantly higher after denture relining in right posterior area, where it was insignificantly higher after relining in left posterior area. Conclusions Our findings revealed that the use of soft denture liner for mandibular complete denture relining significantly improved the occlusal load distribution.

Abstract Background The present study aimed to quantitate the wear of the highly transparent Yttria-stabilized tetragonal zirconia polycrystals (Y-TZP) ceramic monolithic zirconia crown on the enamel in vivo and discuss the prone position of the wear and the underlying mechanism. Methods A total of 43 patients with 43 posterior teeth were selected for full zirconia crown restoration and examined immediately, at 6 months, and at 1 year after restoration. During the follow-up visit, the fine impression of the patients’ monolithic zirconia crowns, the antagonist teeth, the corresponding contralateral natural teeth, the super plaster cast, and epoxy resin model was ontained. The model of epoxy resin was observed under a stereo microscope, and the microstructure parts were observed under a scanning electron microscope. Results After 1 year, the mean depth and volume of wearing of the monolithic zirconia crown were the smallest (all P < 0.01), while those of the antagonist teeth were significantly larger than those of the natural teeth (P < 0.0001), and no significant difference was found among the natural teeth (P = 0.3473, P = 0.6996). The amount of wear after one year was remarkably higher than that at 6 months (P < 0.0001). The microscopic observation revealed the tendency of wearing of the monolithic zirconia crown on the antagonist teeth at the protruding early contact points. Electron micrographs of tooth scars showed that the wearing mechanism of the monolithic zirconia crown on natural teeth was mainly abrasive and fatigue wear. Conclusions Although the self-wearing is insignificant, the monolithic zirconia crown can cause wear of the antagonist teeth via occlusal or early contact significantly; the amount of wearing is higher than that of natural teeth and increases over time. The wearing mechanism is mainly abrasive and fatigue wear.
