Primary failure of eruption (PFE) is a rare disease defined as incomplete tooth eruption despite the presence of a clear eruption pathway with no association to any syndromic disease. Usually ...diagnosed by pedodontists or orthodontists in early age, this diagnosis may be a challenge in adult patients.
This condition should be proposed as a differential diagnosis in adult patients with multiple dental impactions without systemic or syndromic problems, which is suggestive of a PFE not diagnosed in an early age or any another idiopathic eruption failure.
No orthodontic management could be provided in these cases, the management dilemma should take under consideration prosthetic possibilities, associated or not to prior surgical procedures.
We present a case with multiple impactions despite a clear eruption path way. Diagnosis built up was managed by clinical, radiological and biological investigations. Management required multidisciplinary reasoning. Subsequent prosthetic planning using a removable prosthesis revealed the need for surgical intervention. This case highlights diagnosis built up and the conservative treatment options to minimize the risk of iatrogenic damage and unnecessary treatment.
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.
Introduction : Différentes techniques d’empreinte peuvent être utilisées lors de la
réalisation des prothèses amovibles partielles métalliques
(PAPM), l’un des impératifs essentiels est ...l’anticipation de la dualité tissulaire et
le respect des structures d’appui notamment dans le cadre
des édentements terminaux
Objectif : Évaluer les pratiques des praticiens lors de la réalisation des empreintes
secondaires lors des réhabilitations par PAPM et rechercher d’éventuelles
corrélations entre les doléances prothétiques et le non-respect des différentes
normes d’empreinte secondaire.
Méthodes : L’étude a porté sur un échantillon de dentistes exerçant dans la région de
Rabat-Sale-Kenitra au Royaume du Maroc. Le questionnaire a été rempli lors
d’entretiens en face à face ou par les dentistes eux-mêmes. Le questionnaire
informatisé a été envoyé aux dentistes
par e-mail ou via différentes plateformes de réseaux sociaux.
Une étude statistique descriptive et analytique a été réalisée pour traiter les
données.
Résultats : suivant les résultats de l’étude statistique : (57,6%) utilisent seul
l’alginate pour la réalisation de l’empreinte secondaire, (66%)
utilisent des porte-empreintes individuels, (17%) ont recours à l’empreinte composée
partielle dans la gestion des édentements terminaux
mandibulaires, (77%) réalisent le remarginage dans le cadre des cl I et II de K.A.
Concernant les doléances ; les praticiens qui travaillent
avec plus d’un matériau d’empreinte ou ceux qui utilisent uniquement l’alginate ont
rencontré une combinaison de plaintes similaires (75%).
Conclusion : Les pratiques des dentistes interrogés diffèrent que ce soit par rapport
aux matériaux ou des techniques d’empreintes secondaires. On note également que les
doléances exprimées par les patients sont indépendantes de la méthode utilisée. Les
résultats de notre
enquête concordent avec le fait que jusqu’à aujourd’hui il n’y a pas de consensus ou
d’étude qui démontrent la supériorité d’une technique par
rapport à une autre, ou qu’un matériau soit plus fiable pour la l’équilibre de la
prothèse.
L’intérêt de la conservation des racines dentaires en prothèse amovible complète n’est plus à démontrer, Outre le maintien du volume osseux, élément intervenant dans le rétablissement de ...l’esthétique, elle joue un rôle important dans la rétention prothétique (attachements supra radiculaires) ce qui lui confère une indication majeure à la mandibule (surface d’appui réduite). Cependant dans certaines situations d’atrophie maxillaire (palais plat, tubérosités estompées…), l’indication de la conservation des racines dentaires rend difficile voir discutable le résultat esthétique de la PACSR. Le but de notre travail est de mettre le point sur les clés de réussite des restaurations supra radiculaire au maxillaire qui exigent une analyse rigoureuse préalable pour concilier l’optimisation de l’équilibre, la gestion de l’axe d’insertion et le rendu esthétique.
The interest of the conservation on tooth roots in the Removable Complete Denture is no longer to demonstrate. Besides maintaining the bone volume, which is involved in the aesthetic restoration, it plays an important role in the prosthetic retention (Supra Radicular Attachments) giving it a major indication to the mandible (reduced bearing surface). However in some cases of Maxilla Atrophy (flat palate, thin tuberosity…), the indication of dental roots conservation makes the aesthetic result of the PACSR much more difficult to achieve, and even questionable. The purpose of our work is to review the key success factors of supra root maxilla restorations that require prior thorough analysis in order to obtain balance optimization, insertion axis handling and aesthetic rendering.
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.
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.
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.
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%).
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.
