ABSTRACT
STATEMENT OF PROBLEM: Silicone Index Tooth Tray impression system which does not use gingicord has a shortcoming. It takes time to remove internal wall of Silicone Index Tooth Tray for space of wash impression material. PURPOSE: This study was to evaluate whether providing certain space to impression body can prevent from doing complicated laboratory work. MATERIAL AND METHODS: After mounting metal dies with shoulder and chamfer margins arbiturarily, SITT was produced using Blu-mousse(R). In one experimental group, wash impression was taken using Fit-tester(R) without removing interior surface of SITT and in the other group, wash impression was taken using Fit-tester(R) providing 0.5mm space in the SITT and then compared the differences in two groups. RESULTS: 1. There was no significant difference between a group which did not allow space and a group which granted equal 0.5mm space. 2. There was no significant difference between gingival diameter, occlusal diameter of metal die that has shoulder margin and gingival diameter, occlusal diameter of metal die that has chamfer margin. 3. There was no significant difference between a group which did not take pick-up impression and a group which took pick-up impression through relining method using SITT. 4. There was no significant difference between a group that poured immediately after taking primary impression and a group that poured after removing poured stone die. CONCLUSIONS: When taking an impression of an abutment using SITT impression system, it is considered to obtain clinically identical results between a group that did not grant a 0.5mm space within SITT for wash impression and a group which invest a space. Furthermore, it is considered possible to produce an individual die through secondary pouring.

The purpose of this article is the consolidation of several methods in fabrication of Konus denture.It is different Konus denture from traditional Clasped removable partial denture in the procedures of construction.There are multiple procedures of fabrications of inner and outer crowns in the construction of Konus denture.It is important to fabricate the inner crown,the outer crown and the denture framework in construction of Konus denture.Each procedure should be performed exactly.However,there are many procedures in fabrications of them,and thus,the operator and technician bear trial and error.This article consolidate the multiple methods of fabrications of components of Konus denture.The first method is completion of inner crown,outer crown and denture after one impression taking.The second method is the procedures of cementation of inner crown,impression taking of edentulous area,and completion of outer crown and denture.The third method is the procedures of pick up impression taking of inner crown and completion of outer crown and denture on the inner crown of working cast.Each method is acceptable,but operator and technician should be accustomed with their own systemic procedures and minimize the errors in the construction of denture.
