Reinforced single complete maxillary denture

The edentulous state of the oral cavity is equivalent to the absence of any other body part with specific morphological and psychological sequelae. The dentist has a difficult mission in evaluating the biomechanical differences in the supporting tissues for the two arches and applying the appropriate procedures to produce and maintain the conditions necessary for long-term treatment success. The dental literature evidences suggest that the maxillary arch exhibits earlier tooth loss due to various factors and that the mandibular anterior teeth are preserved the longest, so this case focuses on the oral condition in which the maxillary arch is edentulous and opposed by a natural mandibular dentition2. The main problem is that there are important qualitative and quantitative differences between natural tooth and complete denture support. The natural dentition is capable of specialized responses to occlusal demands that preserve its function, whereas the residual ridge is not and it will respond in a variable way depending on age, sex and racial category. Therefore, the replacement of the missing maxillary dentition must provide an optimum distribution of the occlusal forces in order to minimize the negative effects in the compromised edentulous arch. There has been so much debate regarding the Masticatory loads and forces transferring in the case of a single complete denture opposing a natural dentition. In most of the times flexural fatigue and stress concentration is found to be major cause of denture fractures3. So a single complete denture opposing natural dentition should be reinforced to that extent that it should withstand the huge occlusal forces acting on it. Metal can be added in form of wires, bars, mesh or plates. Metal strengthener has a beneficial effect on the fracture resistance of the poly-methyl-methacrylate.
