In this clinical scenario, the patient has a completely edentulous maxillary arch and a partially edentulous mandibular arch (missing molars bilaterally). Constructing only a maxillary complete denture against natural mandibular anterior teeth and missing posterior teeth can lead to several complications. The unopposed maxillary denture would put excessive stress on the remaining mandibular anterior teeth, potentially causing them to splay, migrate, or experience accelerated bone loss. Additionally, the lack of posterior occlusion can lead to an unstable bite and functional problems. Therefore, it is crucial to restore the occlusion in both arches simultaneously to ensure proper function, stability, and long-term oral health.

The modulus of elasticity of PMMA is approximately 2.4GPa. The hardness is approximately 70KHN. PMMA remains chemically stable up to a temperature of 260 degreeF. The typical tensile strength of PMMA is around 50-70 MPa. Therefore, 20 MPa is the incorrect statement.

Local infiltration is a safe and effective technique for achieving anesthesia in most situations. However, it is contraindicated in the presence of infection in the arch because it can spread the infection further or lead to complications like an abscess. Hypertension and kidney problems are not direct contraindications to local anesthesia, but they may require careful monitoring of the patient's condition. Diabetes with urine sugar present does not directly contraindicate the use of local anesthetics unless there are severe complications or neuropathy involved.
