Nutritional considerations in geriatrics

To lead healthy and active life, human beings need a broad range of nutrients. The nutrients required for different physiological age groups can be derived only from a well-balanced diet. One of the major challenges for the success of health sciences in the present scenario is increasing elderly population in the society. Nutritional deficiency, particularly of proteins is very common in elderly people. Over 60% of elderly people are malnourished, and there are many causes for this malnutrition and it is not always easy to differentiate the age-related from the pathological. We always need to remind the phrase that “it is of great importance to add life to years and not years to life.” Here is article reviewing the basics of nutrition in elderly people and the role of prosthodontist in the same

Influence of three different implant thread designs on stress distribution: A three-dimensional finite element analysis

Purpose: Clinical success of implant prosthodontics is dependent in part upon the type of implant thread design. The selection of implant thread design plays an important role in the outcome of the treatment. This study was undertaken to evaluate the pattern of stress distribution using a finite element analysis; hence, the area which would be bearing maximum load for a given design would be arrived. Materials and Methods: Three implants with different thread designs, namely V-thread, buttress, and reverse buttress thread designs were considered and dimensions were standardized. The site considered was the mandibular molar region with cortical and trabecular bone assuming to be isotropic and homogeneous. The implant modeling was done with the CATIA software. Vertical loads of 100N were applied. The stresses were calculated as Von Mises stress criterion. Results: Maximum stresses were seen at the cortical bone and were transferred to the implant. Minimum Von Mises stresses were seen with reverse buttress thread design at the cortical bone. The stresses were observed least at the cancellous bone and maximum at the implant. Conclusion: Hence, within the limitations of this study the results obtained can be applied clinically for appropriate selection of implant thread design for a predictable success of implant therapy
