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.

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.

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.

Processing Errors

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.

Edentulous Patients

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>

The aim of the present study was to assess the effect of a denture adhesive (DA) on patient satisfaction and kinesiographic parameters of complete denture wearers by a cross-over study. Fifty edentulous patients received a set of new complete dentures. After an adaptation period, the participants were enrolled in the trial and randomized to receive a sequence of treatment protocols: Protocol 1- DA use during the first 15 days, followed by no DA for the next 15 days; Protocol 2- no DA during the first 15 days, followed by use of DA for the next 15 days. Outcomes were assessed after 15 days of each sequence of treatment. A questionnaire was used to assess the patients´ satisfaction. A kinesiograph was used to record mandible movements and patterns of maxillary complete denture movement during chewing. The Wilcoxon test (α=0.05) and a paired sample t-test (α=0.05) were used to compare satisfaction levels and kinesiographic data, respectively. Use of DA improved the overall level of patient satisfaction (p<0.001). The kinesiographic recordings revealed a significant increase (1.7 mm) in vertical mandible movements (p<0.001) during chewing and a lower (0.3 mm) vertical intrusion of the maxillary complete dentures (p=0.002) during chewing after using the DA. Use of DA in complete denture wearers improved the patients´ satisfaction and altered mandible movements, with increases in vertical movements during chewing and less intrusion of maxillary complete dentures.

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.
