Abstract
Aim: the study was dedicated to demonstrate the importance of binding the old concepts of preventingthe gag reflex during the prosthodontic work together with the new advance in the concepts, techniques,and materials in this scope. Materials and Methods: Silicone rubber base impression material (OranwashL, Zhermack, Italy) light, and heavy body was used in the study to take the impression by a newtechnique (cheek bite technique) without the use of a tray, and on incremental basis, which showedmore comfort and better results. The prosthesis given to the patient took advantage of the neutral zoneprinciples, which whenever applied it gives better results, it was hollowed, in addition, the procedurecarried less stimulation to the gag reflex, and more assurance. Results: The obturator obtained by thetechnique described was larger in size, lighter in weight, and more comfortable, and efficient in functioncompared to the old one ,the entire procedure from the impression taking, to the delivery, and after, carriedless stimulation of the gag reflex, and gave better results. Conclusion: The advance in the prostheticmaterials, and techniques when combined with the available techniques, and information can givebetter results.

Aim: the study was dedicated to demonstrate the importance of binding the old concepts of preventing the gag reflex during the prosthodontic work together with the new advance in the concepts, techniques, and materials in this scope
The aim of this study was to fabricate a maxillofacial prosthesis for a patient with a palatal defect, and a distinct gag reflex problem in such a way that he faced minimal gagging, and had more comfort during the construction, and after the placement of the prosthesis
The patient had a previous visit to a dental clinic for the construction of a maxillofacial prosthesis 6 months after the operation where the complete healing in the operation site took place, the patient was provided with a prosthesis in which the part filling the defect was solid and much smaller than the defect size, the old obturator became unsatisfactory because of the multiple teeth extraction [Figure 1(No.2)]
Summary
Aim: the study was dedicated to demonstrate the importance of binding the old concepts of preventing the gag reflex during the prosthodontic work together with the new advance in the concepts, techniques, and materials in this scope. Peristalsis becomes spasmodic, uncoordinated, and the direction is reversed, air is forced over the closed glottis producing a characteristic retching sound, patient who gags, presents with a range of disruptive reactions from simple contraction of the palatal, or circum-oral musculature, to spasm of pharyngeal structure accompanied by vomiting [4,5,6,7] This reflex is exaggerated in some individuals [3,8,9], the exaggerated reflex often dissuade the patient from seeking regular oral care, as a consequence, the severely affected patient tends not to seek regular oral care presenting only when in pain, and may request treatment under general anesthesia [7], providing dental treatment for such patient can be a harrowing procedure for all the concerned, the patient inevitably becomes distressed because of uncomfortable feeling of nausea , the dentist becomes irritated at not being able to provide high quality treatment, and the dental nurse has feeling of some impending doom –knowing who will have to clean the mess if the patient vomits [10]. The aim of this study was to fabricate a maxillofacial prosthesis for a patient with a palatal defect, and a distinct gag reflex problem in such a way that he faced minimal gagging, and had more comfort during the construction, and after the placement of the prosthesis
