Optimum amount of occlusal reduction is an essential part of a tooth preparation. Various types of occlusal clearance indicators are being used for the assessment of tooth preparation. All these indicators are used to visualize the clearance for the fabrication of a restoration. The need for knowing all these indicators is of utmost importance to provide quality tooth preparations as well as maintain a harmonious occlusion

Background: One of the chief limitations of Polymethylmethacrylate denture base material is its inadequate mechanical property. Different processing methods of Polymethylmethacrylate have varying influences on the mechanical properties of denture base material. Aim: The aim of our in-vitro study was to comparatively evaluate the flexural and impact strength values between CAD-CAM, Compression-molded and Injection- molded Polymethylmethacrylate specimens. Materials and methods: A total of 66 acrylic rectangular specimens of ISO Standardization (64 x10 x3.3mm) were fabricated. This study was conducted between three groups: Group I (n=22)-CAD-CAM Milled specimens (Ruthinium, India), Group II (n=22)- Compression-molded specimens (Dental Products of India, Chennai), Group III (n=22)- Injection-molded specimens (SR- Ivocap High Impact, Ivoclar Vivadent). Flexural strength was evaluated using four-point bend test and Impact strength by IZOD Impact tester. Kruskal Wallis unpaired test was used to compare the mean values between groups and Mann Whitney U test was used to carry out pair wise comparison. Results: Flexural strength of CAD-CAM samples were found to be statistically highest followed by injection molded specimens. Conversely, Impact strength of injection- molded specimens were highest followed by CAD-CAM specimens. Flexural as well as impact strength values were found to be least among compression-molded specimens. Conclusion: CAD-CAM specimens exhibited higher flexural strength whereas Injection-molded specimens had the highest impact strength.
背景:聚甲基丙烯酸甲酯义齿基托材料的主要缺陷之一是力学性能不足。聚甲基丙烯酸甲酯的不同加工方法对义齿基托材料的力学性能有不同的影响。目的:对聚甲基丙烯酸甲酯CAD-CAM、压缩成型和注射成型试样的弯曲强度和冲击强度进行比较。材料与方法:制作ISO标准(64 x10 x3.3mm)丙烯酸矩形试件66个。本研究分为三组:第一组(n=22)- cad - cam铣削标本(Ruthinium，印度)，第二组(n=22)-压缩成型标本(Dental Products of India, Chennai)，第三组(n=22)-注射成型标本(SR- Ivocap High Impact, Ivoclar Vivadent)。弯曲强度采用四点弯曲试验，冲击强度采用IZOD冲击试验机。组间均值比较采用Kruskal Wallis不配对检验，两两比较采用Mann Whitney U检验。结果:CAD-CAM样品的抗弯强度在统计学上最高，其次是注射成型样品。相反，注射成型试样的冲击强度最高，其次是CAD-CAM试样。弯曲和冲击强度值被发现是最小的，在压缩成型的标本。结论:CAD-CAM成型试样具有较高的抗折强度，而注塑成型试样具有最高的抗冲击强度。

The mandibular torus is an exophytic osseous asymptomatic overgrowth often found bilaterally in the premolar region. Recording this structure in an impression is difficult. This article describes a technique of recording the mandibular tori with a modified stock tray. This novel method reduces discomfort and trauma to the patient and the entire surface of the tori is recorded.

The prime concern of the present-day dentistry is to preserve the tooth, alveolar ridge integrity and periodontium. The treatment option for patients with few teeth include overdentures, immediate dentures or transitional dentures. Transitional dentures are better treatment options as most of the patients defer getting all their teeth extracted. A relatively new type of transitional denture is Cu-sil denture. It is essentially a complete denture with holes which may or may not be lined with rubber gasket, allowing remaining natural teeth to protrude through. This case report represents a simple and economical technique to fabricate Cu-sil denture.

Alveolar bone loss is an inevitable consequence of tooth loss associated with old age. Increased alveolar bone resorption in mandible will lead to prosthetic concerns such as loss of retention and stability in the mandibular denture. Conventional removable complete dentures have long been the treatment of choice for complete edentulism, but it comparatively provides compromised retention, stability and poor masticatory efficiency, at times failing to meet expectations of the patients. To overcome these drawbacks, while retaining some of the remaining natural teeth which will aid in improved retention, stability and support, the concept of overdenture is seen as a patient-friendly and more successful alternative to conventional complete dentures. This case report discusses about the step by step procedure for the fabrication of a bar retained tooth-supported mandibular over-denture that opposes a conventional complete maxillary denture with an identification mark (Photographic method).

External ear anomalies can be caused by genetic or acquired disorders such as trauma or cancer. This flaw has a direct influence on the emotional, social, and psychological well-being of the afflicted. The flaws can be repaired in a number of methods, including prosthetic rehabilitation and surgical reconstruction. The two most challenging components of the treatment are preserving the ear projection during the first phases of auricle repair utilizing grafts and flaps, as well as avoiding the postauricular sulcus from re-epithelizing and obliterating the vestibule. Prosthodontists can address this issue by designing stents that retain the projection of a rebuilt auricle. This case study describes the production procedure as well as the method of retention for an ear stent.

Background: COVID-19 infection has become a serious problem among rapidly growing geriatric individuals in India. During the pandemic, the availability of food and emotional support has decreased in old age homes, and this must have affected the nutritional status and emotional wellbeing of the geriatric individuals. Aim: To evaluate and correlate the association between the nutritional status and emotional wellbeing of geriatric individuals during covid-19 pandemic with dentition and prosthetic rehabilitation. Materials and method: The questionnaire consisted of three sections which included. Demographic data and dental status, WHO approved Mini Nutritional Assessment Short Form (MNA-SF) and WHO approved Emotional well-being five scale. We also compared the BMI of geriatric elders before 6 months of Covid-19 and during Covid-19. 112 participants were enrolled from 9 government old age homes in Tamilnadu, India. Data were collected and subjected to statistical testing. Simple frequency analysis and Chi square test were used. Result: 70.5% of geriatric elders had poor emotional wellbeing and 65.1% were malnourished during this pandemic. Dentition status showed that 51.7% were completely edentulous and 74.1% were without prosthetic rehabilitation. Statistical significance results were found when comparing nutritional status & emotional wellbeing with dentition and prosthetic rehabilitation status of elders during COVID-19. Conclusion: Older adults’ mental health was negatively affected by the COVID-19 pandemic, whereas dentition and prosthetic rehabilitation status indirectly affect the mental health of elders through malnutrition. As a prosthodontist, who provide geriatric care, treating the elders by looking beyond the teeth, will help to improve overall wellbeing of these individuals.

Individually, the existence of a labial undercut, retained natural teeth or a hyper-gag reaction causes considerable difficulty in rehabilitating a patient. However, all three, as seen in this case report, provide a challenge to Prosthodontists' in terms of not just prosthesis fabrication but also meeting the patients' expectations. This case report demonstrates a comprehensive approach to managing with this very challenging scenario.
