Also, if the ideal procedure is not followed, it will lead to a compromised fit of the final prosthesis and failure of the treatment. Alginate impression materials and stones used in the study were mixed with a mechanical spatulator under reduced atmospheric pressure. used for definitive impressions also.4,5 Thus, in these patients, the prosthesis success and overall management depend on the master cast accuracy which turns to the dimensional precision of the alginate impression material. Conclusion: The ideal materials, technique, and armamentarium are required for the long-term success of the treatment for fixed dental prosthesis. Most of the participants used addition silicone with single mix heavy body with light body technique for making final impression and some of them used polyether. Maximum participants used hemostat along with retraction cord. 80% of them used retraction cord for gingival retraction and only few of them used elecrosurgery, lasers, rotary curettage and gingifoam. Provide a 2- to 3-mm depth of alginate beyond the occlusal surface and incisal edge. Extend distally approximately 2 to 3 mm beyond the last tooth in the arch to include the retromolar area. Results: Results shows that, majority of responses indicated use of irreversible hydrocolloid in stock metal tray for making the preliminary impression. Extend facially to include all teeth as well as the musculature and vestibule. After liquifying, the lesser thermostat automatically cools the temp to 150f (65.5c) 2) the second bath becomes a STORAGE bath that cools the material, readying it for the Impression. Data were analyzed by using SPSS 19 software. Immersing the tube of material in a special water bath called a hydrocolloid conditioner at 212f (100c) liquifies the material. Patient should rinse and all alginate should be removed from the patient’s face. Figure 8.3.4: Placement of maxillary tray. The procedure for taking the impression is repeated (see Figure 8.3.4). A self-administered anonymous questionnaire was distributed to the participants. The maxillary impression is taken with the clinician standing at about 10.0011.00 o’clock, beside and slightly behind the patient. Ethical approval for the beginning of the study was obtained via Institutional Review Committee, Ibn Sina National College for Medical studies, Jeddah. Material and methods: A questionnaire based survey was conducted among the dental practitioners of Makkah region of Saudi Arabia. A lot of research has been done by the different scientific community to develop biofilms for fulfilling the need for sustainable human health. The aim of this survey was to integrate impression techniques evolved all over the years for fixed partial dentures and to know the techniques and materials which are used in the present day by the practitioners. Due to their unique properties, alginate-based biomaterials have been extensively used to treat different diseases, and in the regeneration of diverse organs.
