Abstract

It is known that Article Alkambozi the resin is one of the best types of cosmetic insects used in the treatment of each of the front and rear teeth either.
It is also poor mechanical properties and polymerization shrinkage during its impact on the strength of the adhesion of the filling body Age of the most important obstacles to the success of a permanent Alkambozi as a filler material .
Searching the roads polymeric indirect one of the best solutions to those obstacles as they allow for shrinkage polymerization out before sticking body Age violin it increases the mechanical properties of the material by increasing the proportion of turning the polymer of Mthblmr that affect the number of links carbon non- mutant located inside the material Alkambozi which turn may Tather of the strength of link between Alkambozi and resin adhesive .
Therefore, study the effect of different polymerization methods with the difference in the proportions of the polymer to shift Mthblmr on the strength of link between Alkambozi and adhesive resin can be of value.
As well as the comparison between the use of two different types of adhesive resin and assess the role of storage in distilled water at 37 ° C for two different periods can be useful ways to use Applied substance resin Alkambozi .
Three different systems used of resin Alkambozi material ( cooking Kamiaúa , light cooking, heat cooking) as well as two types of adhesive resin in the water - loving manufacturing hundred sample n Alkambozi .
Manufactured parts samples first group of Alkambozi -style cooking as manufactured parts samples of the second group of Alkambozi Light Cooking, The third group was made ​​first of Alkambozi light cooking and then exposed to more light cooking for six minutes , as well as parts of the fourth group First made of Stumble Light cooking oil , and then exposed to heat treatment at 100 ° Mioaholmdh seven minutes .
The fifth group have made parts sampled Alkambozi the heat and pressure cooked together at 120 ° C under six units of pressure for 10 minutes.
* An analysis of the results of previous groups have been developed with the following :
1. Be affected by Qhy and linkage between Alkambozi and adhesive resin had a positive impact in different ways for the polymerization substance resin Alkambozi .
2. Is Alkambozi the monomer direct ways better than the gap where it has recorded the highest values ​​of a measure of the strength of linkage with the adhesive resin .
3. The relationship between different polymerization methods and accurate leak about charges Alkambozi of the things omitted recommended and studied to show how Tatahma the success of those fillings.
4. Was to store the samples in distilled water for a month after a positive to lose measure the forces binding rate for all groups at all.
