Final answer:
The most technique-sensitive cement during mixing is high-strength resin cement, requiring precise measurement and blending of base and catalyst pastes. Technique sensitivity arises from factors like maintaining dry conditions, controlling temperature, avoiding air bubbles, and adhering to specific working and setting times.
Step-by-step explanation:
During mixing, the most technique-sensitive cement is high-strength resin cement. This type of cement is often used for luting indirect restorations such as crowns, bridges, inlays, and onlays. It requires meticulous attention to detail in the mixing process, as the proportions of the components must be precisely measured and thoroughly blended to achieve the desired properties. Incorrect mixing can lead to suboptimal cement properties that compromise the strength and longevity of the restoration. The process usually involves mixing a base and catalyst paste, following manufacturer-specific instructions on timing and proportions.
The technique sensitivity stems from various factors, such as the need for clean and dry conditions, control of the ambient temperature, and avoidance of introducing air bubbles. There are also parameters to be respected regarding the working and setting times, which can affect the handling characteristics and the ultimate bond strength. The clinician must also consider the preparation of the tooth surface, which can include etching, bonding agents, or primers, depending on the specific type of resin cement being used.
