After surgical excision of tumors involving the maxilla, depending on their location and size, maxillary defects can have harmful consequences, both esthetic and functional. These effects disrupt all the functions of the manducatory system, namely breathing, swallowing, and especially phonation, thus affecting negatively the patient’s psychological state. Despite the evolution of reconstructive surgical techniques and the development of microsurgery, conventional obturator prostheses are still relevant. In fact, these prostheses restore the main functions of chewing, phonation, and swallowing. They also provide the patient with a satisfactory esthetic appearance. Moreover, they have an advantage in regard to oncology, making the possibility of surveying much easier. Maxillary defects are characterized by their highly polymorphic aspect, having a great impact on the nature of prosthetic rehabilitation. The aim of this work was to present the different clinical and laboratory steps of prosthetic rehabilitation of an acquired maxillary defect following excision of a mucoepidermoid carcinoma.

Limited oral opening is an acquired or congenital abnormal condition that compromises patient esthetics, nutrition, and quality of life. In addition, it may hinder conventional prosthetic procedures of edentulous patients, make it challenging, and present difficulties at all its stages. This clinical report presents different clinical treatment options suitable to be chosen by the prosthodontic carer in the case of reduced oral aperture.

With senescence, edentulous patients present unfavorable clinical situations following the continued resorption of alveolar bone and the inevitable narrowing of the prosthetic corridor. That's why rehabilitation with removable complete prosthesis presents a difficult challenge for the dentist. In this connection, the use of the piezographic technique, a promising therapeutic approach, makes it possible to better respect the physiology of the elderly patient while ensuring a compromise of retention, prosthesis stability and comfort. The aim of this manuscript is to present the different stages of realizing a removable complete denture resulting from an impression of the bearing surfaces and a piezographic recording of the prosthetic corridor through a clinical case.

Introduction: For a long time, the prevention of cross-contamination in dentistry has mainly been concentrated in the operating room. Activity related to laboratory work, a potential source of pathogen transmission, is therefore often overlooked. In addition, the practice of prosthodontics often gives the impression that aseptic measures cannot be rigorously applied. Several factors account for this situation. Designing a prosthesis involves handling a certain number of potentially contaminated and heat-sensitive objects (prostheses, impressions, wax tubes, occlusion bites, etc.). The items transferred between the dental office and the dental laboratory as well as the prosthetic instruments constitute the main chain of cross contamination in prosthodontics. Thus, an evaluation of the dentists and prosthetists’ compliance with regard to their asepsis through a cross-sectional study was necessary. Methods: two anonymous questionnaires were distributed. The first was among the dentists and the second to dental prosthetists in the public and private sectors.  Results: From the 302 questionnaires distributed, only 220 were filled-in. 78% of the dentists and 37% of the prosthetists know the disinfection protocol of reusable instrumentation. 80.3% of the dentists and 74.1% of the prosthetists disinfect their prosthetic work but with varying percentages according to the group of items (impressions, prosthesis, etc.). 71.5% of the practitioners and 18.5% of the technicians disinfect their laboratory instruments systematically. However, 45% of the dentists and 54% of the prosthetists think they are not exposed to infections. Discussion: The results showed an insufficient level of knowledge and compliance to ensure asepsis of the prosthetic work both in the public and private sectors, contributing to a relatively high level of exposure to infections compared to a Canadian study. Conclusion: Given the insufficient compliance and in order to remedy these deficiencies, a simple decontamination protocol is suggested. Improving awareness and providing continuous training are then required.

Through this study we aim firstly, to understand the correlation between pain, intensity of pain and different clinical Data. Secondly, to highlight the accurate etiological diagnosis and be able to take the adequate decison for pain managment. This study was carried out on 200 edentulous patients who came to the departement of complete denture of dental clinic at Monastir Tunisia from february to june2019.All the patients were examined and assessed by one prosthodontist under the supervision of a professor. A questionnaire was used to record information wich was taken directly from the patient when they attend the dental clinic. The patient consent were taken verbally. The questionnaire included 19 questions divided in 3 heading: Medical history, exploration of pain and its intensity and Management strategies. The statiscal analysis were done with an SPSS's logiciel version 22.0. The results are presented in form of tables and graphics. Moreover, in this study the most common chief complaint was pain 63% of the sample. This result corroborate with other studies in litterature. Besides, a statistically significant relationship was observed between pain and patient’s satisfaction with their prosthesis (P=0.044<0,05). However, no significant difference was found between pain and other differents clinical Data (age, gender, general condition ….) (P>0.05). Neither between intensity of pain and different clinical data (P<0.05). This result came in argument with results of other worldwide researches. Finally, we came to the conclusion that management strategy of pain must follow a comprehensive, multidisciplinary and systemic approach.
