[Maxillomandibular relationship recording in removable partial petal dentures (RPMD)]. / Enregistrement du rapport maxillo-mandibulaire en prothèse amovible partielle métallique (PAPM).

The recording of the maxillo-mandibular relationship (MMR) is an essential and unavoidable step that occurs at different stages of treatment during a prosthetic rehabilitation. Tissue duality is a major problem in metal partial dentures (MPD), especially in complete and large edentulisms, and is responsible for occlusal inaccuracies resulting in restorations that are not integrated with the patient's manducatory system. In order to perform this step, the practitioner must choose the right material, make the appropriate support, and adopt a reliable and reproducible technique that is adapted to the clinical situation and the prosthetic step. The objective of this work is to suggest a simple and codified approach, which guarantees a reliable recording of the maxillo-mandibular relationship, adapted to the particularities of the supporting structures and taking into consideration the clinical sequence for an optimal occlusal-functional integration of the future metallic partial denture.

Impression techniques in Removable partial denture: epidemiological study.

INTRODUCTION: Various impression techniques are used in the realization of free-end extension partial denture, one of the imperatives is to respect the compressibility and behavior of the tissue during impression making as well as during function. AIM: To evaluate the knowledge and practices of private practitioners regarding secondary impressions made during the management of terminal edentulism with metallic removable partial denture, and to search for possible correlations between prosthetic complaints and non-compliance with the various final impression standards in terms of materials, equipment and techniques. METHODS: The study involved a sample of dentists practicing in the Rabat-Sale-Kenitra region in the Kingdom of Morocco. The paper questionnaire was filled out in face-to-face interviews or by the dentists themselves. The computerized questionnaire was sent to the dentists by e-mail or via various social network platforms. A descriptive and analytical statistical study was carried out to treat the data. RESULTS: Following the results of the statistical study: (57.6%) used the alginate as a secondary impression material, (66%) used individual trays, 17% used models from primary impressions for direct prosthesis fabrication, (17%) used the cast impression technique in free end mandibular edentulous. (77%) recorded the peripheral joint in Kennedy Applegate class I and II, concerning the complaints; practitioners who worked with more than one impression material or those who use solely the alginate encountered a combination of similar complaints (75%). CONCLUSION: The practices of the dentists differ in terms of materials and techniques used in the management of edentulous terminals by removable partial denture (RPD). The complaints expressed by patients were independent of the method used in the secondary impression. The results of our survey concur with the fact that until today there is no consensus to demonstrate that a technique, or a material can be more reliable for the stability and the success of the RPD.

Les mini implants dans la stabilisation de la PAC

La prothèse amovible complète (PAC), malgré tous les progrès qu'à connue la dentisterie, constitue jusqu'à nos jours une thérapeutique très répandue dans nos populations. La PAC bénéficie actuellement de la possibilité de voir ses avantages et ses impératifs d'équilibre nettement améliorés par la mise en place d'implants. Cependant, dans un certain nombre de cas, les déficits du volume osseux peuvent contre-indiquer l'utilisation d'implants standards sans aménagement préalable de la crête, lorsque cela n'est pas souhaité par le patient pour des raisons financières, d'allongement du temps de traitement ou du nombre d'intervention, etc., ou par le praticien pour des raisons anatomiques ou médicales, les miniimplants prennent leur place d'alternative de choix. Technique reconnue par la FDA (Food and Drug Administration: 12 mai 1998). Son taux de survie avoisine celui des implants de diamètre plus large. Le confort fonctionnel et esthétique immédiat et le coût modéré de cette technique expliquent son succès. A travers un cas clinique nous allons passer en revue le protocole chirurgical et prothétique et essayer de démontrer jusqu'à quelle mesure cette solution thérapeutique peut répondre aux exigences de nos patients en comparaison avec une stabilisation conventionnelle avec des implants standards
