  46. 46. Prosthetic considerations :    Geriatric nutrition : Since the prosthodontist works primarily with the middle and older age groups,,he is most concerned with the general health and well being of the older patient. It is a common tendency to become so engrossed with the technical details of the denture construction that we loose sight of the patient as a whole. www.indiandentalacademy.com
  47. 47.  Nutritional problems may be difficult to handle in older people as eating habits of a liftime are not easily changed.  The prosthodotist who gives some thought to the importance of NUTRITION , can help the older patient make the most of his limited functional resources , and can spare the patient many f the consequences of nutritive deficiencies . www.indiandentalacademy.com
  48. 48.    The most common oral complains of this age group results from the fact that aged mucosa is friable and easily injured . There is also good evidence that prosthetic failures are often, the result of tissue deficiencies rather then technical deficiencies. It is therefore obvious, that the dentist gives importance to the DIET AND NUTRITION of this age group www.indiandentalacademy.com
  49. 49. Calorie requirement of the elderly • • • With age the calorie requirements for general bodily processes continually decreases. The average adult calorie requirements are : 10% less at age 60 20% less at age 70 25% less over age 90 The dentist should therefore advise the older patients to curtail foods with high fuel or calorie value ;because “AN OBESE PERSON IS A SICK PERSON ,AND SICK PEOPLE ARE POOR DENTURE PATIENTS”. www.indiandentalacademy.com
  50. 50. IMPORTANCE OF PROTEINS  As the patient becomes older , the amount of protein required per kg of body weight is increased.  1.4gm/k body weight is optimum.  Too much protein never damages the health of the elderly person.  Milk is an ideal source of proteins for this age group. www.indiandentalacademy.com
  51. 51. Importance of vitamins  1. 2. 3. 4. Intake should be increased for the following reasons: Provide nervous stability. Provide resistance to bacterial infections. Improve digestive efficiency by aiding the use of carbohydrates and utilization of mineral elements. The intake of vitamin A, B-complex, C and D should be increased mainly . www.indiandentalacademy.com
  52. 52. Importance of minerals  Minerals of of considerable importance to the aged person.  Ca loss contributes to bone fragility .  They often experience a rapid and excessive ridge resorption, under complete dentures which may be related to negative Ca balance; which is also one of the prime causes o OSTEOPOROSIS. www.indiandentalacademy.com
  53. 53. www.indiandentalacademy.com
  54. 54.     Thus the inclusion of Ca and PO4 in the diet is absolutely important as the prime mineralizing substance of bone . Minute quantities of trace minerals are also important , which include: cu, mn, zn, mg, I2, K, Na… Ca levels may be improved by increasing the intake of milk and milk products plus a VIT D supplement of 400-1000units/day. Acidulated milk with a soft curd is especially valuable. www.indiandentalacademy.com
  55. 55. Geriatric nutrition and osteoporosis     1. 2. 3. 4. 5. Results from the loss of bone, especially the spongy spicules of bone which support the weight bearing parts of the skeleton. Common in the- aging person -postmenopausal women. Causes: Lack of Ca intake . Lack of Ca absorption. Lactase deficiency. Lack of blood circulation. Low estrogen levels. The prosthodontists are in a strategic position to intercept early evidence of osteoporosis and educate the patient towards good nutrition. www.indiandentalacademy.com

  58. 58. APPLICATION           The essential requirements of the daily diet having been described , the simplest and the most practical nutritional system to follow is the BASIC SEVEN , which provides an excellent scheme for a daily plan on eating and which could be used by the prosthodontist to check the adequacy of the patients diet. The basic seven consists of the following 7 food groups: Group 1 : green and yellow vegetables. Group 2 : citrus fruits, tomatoes, raw cabbage or salad green . Group 3 : potatoes and other vegetable fruits. Group 4 : milk and milk products. Group 5 : meat , poultry , fish , eggs (if expensive increase group 4 ) . Group 6 : enriched or whole grain cereals and bread. Group 7 : butter or margarine ( if expensive increase group 1 and 4 ) www.indiandentalacademy.com

  60. 60. NUTRITION FOR NEW DENTURE WEARER DIET FOR THE FIRST DAY : A liquid diet which may consist of fruit juices, milk, etc  DIET FOR THE SECOND AND THIRD DAY : Soft food that requires a minimum of chewing like milk , eggs, noodles,etc.  DIET FOR THE FOURTH AND LATER : As the sore spots have healed firmer foods can be eaten.  www.indiandentalacademy.com
