Traitement de la biproalveolie pathologique par prothese adjointe partielle

Le sujet africain mélanoderme se caractérise par une biproalvéolie qui à la vue des études menés par Djaha peu être toléré.Dans certains cas, une intervention s'impose à nous,soit pour rectifier l'angle formé par les dents antérieures soit de façon plus radicale pour extraire les dents car fortement mobilisées.Dans cette perspective la prothèse adjointe donne une solution intéressante à deux niveaux.L'acception par le patient du choix thérapeutique et la conduite du traitement.Nous nous proposons au travers d'un cas clinique de présenter une approche diagnostic et de traitement

[Choice of size of anterior teeth in black African patients]. / Choix de la dimension des dents antérieures chez le sujet mélanoderme d'Afrique.

The choice of the size of artificial teeth takes an important place in the treatment of edentulism with removable prosthesis. However, the standards or proportions commonly used as guide have been developed mainly on Caucasian populations. This study have been undertaken to determine some proportions between anterior upper teeth and some maxillo-facial structures in black African subjects. The results suggest that the proportions generally used to choice the anterior upper artificial teeth in Caucasian subjects can not been applied in melanoderme African patients.

[Toward a more resistant resin, more economical and better suited to conditions in developing countries]. / Pour une resine plus resistante, plus economique et adaptee aux contextes des pays du sud.

The breakage of prosthesis constructed in polymethacrylate resin is a reality in daily practice. Several solutions have been proposed to overcome this problem. Thus, the reinforcement of resin with carbon fibre improved greatly the mechanical properties, notably the fatigue strength. The technique of elaboration of such prosthesis proposed in this study has little impact on aesthetic as well as on the final cost. This proposition could be a relevant solution for third world countries opposite to economical and technological problems generated by cast metallic framework.

[Occlusal-articular impact of late consultation]. / Consequences occluso-articulaires des consultations tardives.

Partial toothlessness, lately or wrongfully compensated, are at the origin of prosthetics problems often difficult to solve. We shall explain the importance of dental grooves in the prosthetics process, through different cases of temporomandibular dysfunction.

[Removable prosthesis: masticatory efficiency]. / Prothese adjointe: efficacite masticatoire.

The late consultation in odontology often leads to tooth extraction. This negligence, in a long term, will cause complete toothlessness. This state of invalidity will be compensated by prosthesis. The removable prosthesis is often indicated because of the cost price. It is the result of a successful therapeutics, only if it fits aesthetically and functionally, within a chewing efficiency. In a first part, we will define masticatory efficiency, as different from masticatory capacity and capability. Then, in a second part, through some experimentation, we will show how fundamental research can guide the practitioner in his prosthetics choices and assessments.

[Orodental diseases and school absences. Evaluation of a school population of 278 students. Preliminary study]. / Affections bucco-dentaires et absences scolaires. Evaluation sur une population scolaire de 278 élèves. Etude préliminaire.

In the framework of an important evaluation survey on absences at work position due to bucco-dental problems, a preliminary study in undertaken in school environment on a sample of 278 children attending examination classes from Abidjan three districts (Adjamé, Williamsville, Cocody). Results show that: 34.89% among children have been absent at least one time of which 19.78% for pulp pain, 22.66% of the sample have got a rest and for 14.02% among them, the rest was at least a day. These absences results in a waste in annual hourly volume from 2.69% to 8.08% of the annual hourly quota in terms of dispensed Cowes's in Ivory Coast primary schools. The results show that bucco-dental pathologies and their corresponding i.e. school absences have a repercussion on pupils attendance regularity at school and with no doubt on schools results. They indicate the necessity to put an emphasise on the prevention and the early treatments of these affections.
