The retention, stability and comfort of wearing denture is greatly influenced by the flow, quantity and consistency of saliva. Insufficient salivary output results especially in old-aged edentulous patients may result in denture sores because of lack of lubrication by saliva, thus, reducing patient’s ability to retain the prosthesis. Various approaches have been concernes with the use of reservoir with holes have been described in the literature. However the flow of salivary substitute is very difficult to control. Moreover the frequent cleaning of the denture required to maintain the patency of the reservoir holes poses various challenges to the patient. This article explains a novel technique for the incorporation of a reservoir with controlled salivary flow in complete denture to enhance the retention of the prosthesis and thus, improving the comfort of wearing denture and the speech of patient.

The retention and comfort of wearing prosthesis mainly depends on saliva. In reduced saliva conditions, such as xerostomia or radiation therapy, the oral mucosa tends to become dry and ulcerated, leading to the patient's inability to retain the prosthesis. Various techniques have been reported in the literature regarding the use of a reservoir with holes in dentures. The results have not been satisfactory because the flow of the salivary substitute could not be controlled and with frequent cleaning of the denture being necassary to maintain the patency of the reservoir holes. A newer technique for incorporation of a palatal reservoir with controlled artificial salivary flow in complete denture is being explained in this article, which improved the denture retention, comfort, mastication and speech of the patient.

The aim of this study was to provide longitudinal evaluation of the changes after complete dentures therapy and the rate of residual ridge resorption through a six-year period of denture wearing. The authors presented the case of a 76-year-old patient, edentulous for twelve years, wearing complete dentures for six years, with the eugnat jaw relationship. Cephalometric radiograph was carried out in the process of new complete denture production, while the evaluation was carried out after six years. Cephalometric analysis was performed by using ?Dr. Ceph? computer software (FYI Technologies, GA, USA). After six years, the reduction of anterior total facial height was 5.5 mm and the anterior lower facial height was 5.5 mm, the vertical residual ridge reduction of the maxilla was 1.4 mm and the reduction of the mandible was 3mm. The study confirms the reliability and advantages of cephalometric analyses and reveals their application possibilities in prosthetic diagnostics and therapy, as well as in evaluation of rehabilitative results in edentulous patients and longitudinal analysis of changes on the orofacial complex tissues and intemaxillary relationships.

There has been an increase in the incidence of complete edentulism among the elder patients. Complete dentures are the most common and preferred treatment of choice. Complete dentures help in masticatory function and restore the facial shape of the edentulous patients. Fabrication of the complete dentures is, therefore, a very important task for the clinician to ensure patient satisfaction. Errors may occur during the denture fabrication and these are called processing errors. It is a multifactorial process. The aim of the survey is to study the errors that occur during processing of a complete denture. It is a questionnaire based study conducted with a batch of 100 dental students. The questionnaire consisted of 16 questions focused on different fabrication techniques, timing, materials used, etc. by various students. The data collected was represented statistically and discussed. Dough technique was the most preferred method adopted by 39% of the students. Shorter curing cycles produced less defects, but majority of the students used longer cycles (41%). Most of them reported fractures (16%) and microporosities (11%) as defects. We can conclude that there are a few areas of error during the processing of dentures by the dental students. The incidence of these errors, however appears to be low. There is a scope for CAD/CAM complete dentures in the future to eliminate the possibilities of errors.

Background/Aim. Balanced occlusal arrangement of artificial teeth and balanced occlusion is a specific type of occlusion that preserves the stability of complete dentures. Balanced occlusion comprises realization of tooth contacts at the working side as well as at the balancing side, at the same time. The aim of this study was to assess the influence of balanced occlusal arrangement of artificial teeth on the decrease in reduction of edentulous alveolar ridge. Methods. A longitudinal study on 91 fully edentulous patients was conducted using their panoramic radiographs and parameters of vertical dimension of edentulous ridges. All the patients were clinically examined by the same and a qualified dental practitioner. Numerical values of parameters of vertical dimensions of edentulous ridges and lines were statistically processed and compared using the Student?s t-test. Results. Vertical dimensions and heights of edentulous ridges were different after comparison of parameters in complete denture wearers with balanced occlusion and complete denture wearers without bilaterally balanced occlusion, as well as between male and female edentulous patients. Statistically significant differences of heights were established in complete denture wearers? with a set of artificial teeth without balanced occlusion, at the baseline and 12 months after wearing of complete dentures. Conclusion. Balanced occlusion is a favored occlusal design in setting of artificial teeth in conventional complete dentures, which preserves edentulous ridge and influence the stability of dentures.

ABSTRACT Purpose The retention of complete dentures is frequently difficult in edentulous patients with a severely resorbed residual alveolar ridge. In such cases, implant overdentures having a stronger retention force are useful. Although there are various types of attachment systems for implant overdentures, they are frequently complicated. We are, therefore, developing a simple attachment system focusing on a soft lining material for the female connector. The purpose of this study was to evaluate the retention force of implant overdentures applying a soft lining material for the attachment. Materials and methods The models in which seven male and female connector pairs were used. As the control, a rubber O-ring attachment system, in which a rubber O-ring female was paired with a metal ball anchor (male), having a diameter of 1.7 or 2.2 mm. In the attachment system with a soft lining material, a female component was made up of soft lining material paired with a male having a diameter of 1.7, 2.2, 2.5, 2.7 or 3.0 mm. In measuring the retention force, the maximum force required to dislodge the male from the female was recorded by a digital force gauge. Results With the rubber O-ring, the retention force was 2.9 ± 0.2 N for the 1.7 mm male and 3.3 ± 0.3 N for the 2.2 mm male; these values were higher than the respective retention forces when using a soft lining material as the female and a male of the same diameter. However, with the female comprising soft lining material, the retention force exceeded 4 N for the 2.5, 2.7 and 3.0 mm males and was higher than the retention forces for the rubber O-ring. Conclusion The proposed attachment system with soft lining material for implant overdentures provides a clinically sufficient retention force when the diameter of the male exceeds 2.5 mm.

The mucosa that covers the residual ridges of edentulous patients may present some distortion or displacement when occlusal loading is applied in complete dentures. This distortion and movement of the denture can result in acceleration of residual ridge resorption and loss of retention and stability. The aim of this study was to analyze the pattern of upper complete denture movement related to underlying mucosa displacement. A sample of 10 complete denture wearers was randomly selected, which had acceptable upper and lower dentures and normal volume and resilience of residual ridges. The kinesiographic instrument K6-I Diagnostic System® was used to measure denture movements, according to the method proposed by Maeda et al.7, 1984. Denture movements were measured under the following experimental conditions: (A) 3 maximum voluntary clenching cycles and (B) unilateral chewing for 20 seconds. The results showed that under physiological load, oral mucosa distortion has two distinct phases: a fast initial displacement as load is applied and a slower and incomplete recovery when load is removed. Intermittent loading such as chewing progressively reduces the magnitude of the denture displacement and the recovery of the mucosa is gradually more incomplete.

<p><strong>Background</strong>: A realistic approach to the phonetic aspect in complete denture construction is most often subdued by various factors. The palatal rugae, an important landmark in speech orderliness, are frequently affected due to lack of proper texture on a complete denture. Establishing a correlation between customized palatal surfaces of complete dentures and speech improvement will help to ameliorate post insertion appointments of articulation deficiencies.</p><p><strong>Methods: </strong>Ten completely edentulous subjects of either sex with a mean age range of 50-70 years, fulfilling the inclusion criteria were included in this study. All the participants received three sets of dentures, followed by assessment of speech using photo articulation test, speech intelligibility and acoustic analysis in edentulous state and subsequently after insertion of conventional denture, denture with customized rugae, and denture with customized metallic base.</p><p><strong>Results:</strong> The data collected was subjected to statistical analysis using SPSS 24.0 version and GraphPad Prism version 5. The statistical analysis was carried using ANOVA and student t-test. On evaluating the error patterns, distortion was maximum followed by substitutions. These errors were maximum in edentulous state and decreased subsequently, with the least errors in customized rugae dentures. A statistically significant positive correlation (p&lt;0.0001) was found.</p><p><strong>Conclusions: </strong>Apart from retention, stability and support, equal amount of emphasis has to be laid down on phonetical aspects to improve the overall psychological well-being and social upliftment for patients. The improvement in verbal proficiency for completely edentulous patients can be minimized considerably by customizing the palatal portions.</p>
