Background: Ridge morphology is one of the important recognized factors affecting denture retention, stability, support and masticatory function in edentulous patients. The form of ridge affects the planning as well as determines the prognosis of treatment. The objective of this study was to assess maxillary residual ridge morphology according to American College of Prosthodontists (ACP) classification system and to find association between type of ridge morphology of maxillary arch with age and duration of edentulism.     Methods: The study was conducted among 87 completely edentulous patients above 40 years of age visiting department of prosthodontics Nepal Medical College. The morphology of maxillary residual ridges were clinically evaluated and classified according to criteria given by American College of Prosthodontists (ACP) classification system. The findings were associated with age, sex, duration of edentulism and complete       denture wear. Results: In this study, more than two thirds of the patients belonged to the age group of 60 – 80 years and their mean duration of edentulousness was seen to be 5.7 years. One fifth of the patients were using previous complete dentures. Type A maxillary ridge morphology was found to be the most prevalent. The type of maxillary ridge morphology was not found to be associated with either age or gender of an  individual however it varied significantly with length of edentulism and duration of complete denture wears.              Conclusions: Within limitations, it can be concluded that maxillary ridge morphology was not associated with age of an individual however the longer duration of edentulism or complete denture use would make the type of ridge morphology more unfavorable. Keywords: maxillary ridge; length of edentulism; residual ridge resorption; ridge morphology.

Background: The aim was to determine utility of Cartridge based nucleic acid amplification test (CBNAAT) in diagnosis of mycobacterium tuberculosis in children with neurotuberculosis diagnosed on the basis of clinical evaluation, CSF findings and neuroimaging.Methods: A prospective randomized controlled trial was conducted in Pediatric Department of RNT Medical College, Udaipur, Rajasthan, India from July 2017 to June 2018. Total 110 children of age group of 6 months to 18 years with the diagnosis of tubercular meningoencephalitis (TBME) on the basis of clinical evaluation, CSF examination and neuroimaging were included in the study.Results: A total 110 children were enrolled. Maximum number of cases admitted with TBME were among 1-5 years of age group (60.91%). CSF and gastric aspirate were examined by CBNAAT for MTB. 5 (4.55%) children had CBNAAT positivity in CSF. Gastric aspirate was positive among 16 (14.55%) children. None of the patient had CBNAAT positive result both in CSF and gastric aspirate.Conclusions: TBME is a major health problem in children below 5 years. Gene Xpert assay has the potential to significantly improve and escalate the diagnosis of smear-negative body fluid specimens. CBNAAT for mycobacterium tuberculosis was positive in 5 (4.55%) children from CSF and 16 (14.55%) from gastric aspirate. Negative CBNAAT should not prevent any patient with suspected features of TBME from starting anti tubercular treatment (ATT) as sensitivity of this test remains low. Final judgement to start ATT should be based on clinical, biochemical and radiological profile especially in CNS tuberculosis.

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.

ABSTRACT Objective To determine the denture hygiene habits in complete denture patients according to their age and time of dentures. Methods In this study a self administered structured was developed to know the attitude of the patients regarding denture hygiene in the department of Prosthodontics. The total study sample consisted of 230 subjects including 124 (53.9%) males and 106 (46.1%) females. Data was analyzed using SPSS version 15.0 with chi-square test at p-value <0.05. Results Nearly half of the subjects clean their dentures daily once. Participants from the younger age group and who had been wearing dentures since 2 years maintain better frequency of cleaning. The majority of these subjects used water and brush for denture cleansing. After seeing the condition, half of the dentures were rated as good 50.3%, followed by fair and poor as 29.5 and 20.2% respectively. Clinical significance Poor condition of complete dentures seen in the population is mainly due to irregularly cleansing habits and also less usage of cleansing solutions. Dentists should give proper instructions regarding maintenance of denture hygiene. How to cite this article Apratim A, Shah SS, Sinha M, Agrawal M, Chhaparia N, Abubakkar A.

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 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.

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.

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.
