based on paraffin wax with
bees wax

points in the range 49–58ºC.
It is used
to form the base of the denture and in setting of teeth
------------
D_ White wax:: to make pattern simulate veneer facing in crowns. | 308 |

Used as a casting wax to establish minimum thicknessto certain areas
Used as a utility wax to prevent distortion of impression materials.

| 12 | Care of the cast
لازم ما نغسله بماء عادي .
ليش ؟!
لان تذوب الطبقه الخارجيه
شنو نستعمل ؟
نستعمل محلول خاص اسمه "slurry water '‘. | 244 |
| 13 | عدنه اختبارين لل setting time
الاول عباره عن ابره (نيدل) وعليها وزن نراقبها لحد ما gloss is lost

| 15 | بالنسبه لل Tensile strength
Gypsum is a brittle material,
the tensile strength of
dental stone is twice than that of plaster
_It is significant in
fracture of teeth in the cast while separating from the
impression, | 207 |
| 16 | 4_Chemicals
اضافة هذي المواد يقلل ال strength
ليش؟!
This is due to the reduction in the
inter crystalline cohesion | 226 |
| 17 | 3_Drying
اذا كان بالحاله Wet يعني بيها water راح يكون ال strength قليل
اما اذا كان dry راح يكون ال strength ضعف الحاله الاولى | 220 |
| 18 | 3_ Mixing
اذا كان بشكل صحيح راح تزيد عدنا ال strength
اما اذا صارت عدنه زياده بال Mixing راح يقل ال strength ليش؟!
لان يصير عدنا تكسر بال crystals | 207 |
| 19 | 2_ Porosity
نعاملها معاملة ال W/P
لان عند ما يزداد تزداد ال Porosity واكيد هنا يقل ال strength | 183 |
| 20 | Factors effecting the Strength :
1. W/P ratio
لمن يزداد هذا المعدل يقل ال strength
ليش؟!
The excess water reduce the cohesion between
the crystals themselves 40% of the strength يقلل الترابط بين الجزيئات | 221 |
