What is your process for ensuring that a dental appliance meets the specifications provided by the dentist?

What they want to know is how you ensure accuracy and quality in your work to meet the dentist’s requirements. You need to say that you carefully review the prescription, follow precise fabrication methods, and thoroughly inspect the appliance to confirm it fits and functions correctly before delivery.

Example: When I receive a dentist’s instructions, I carefully review the details to fully understand their expectations. During fabrication, I focus on maintaining precision and consistency to match those requirements. Before handing over the appliance, I double-check the fit and finish, sometimes comparing it against models or previous cases to ensure everything aligns perfectly with what’s needed. This approach helps avoid any last-minute adjustments and keeps the dentist’s trust.

Can you explain the importance of occlusion in dental prosthetics?

What they want to know is that you understand how occlusion affects the fit, function, and comfort of dental prosthetics, and how you use tools like articulators to ensure proper alignment. You should explain that correct occlusion prevents discomfort and extends the life of the prosthetic by avoiding premature wear and that you assess and adjust occlusion carefully to achieve these outcomes.

Example: Occlusion is key to making sure dental prosthetics fit comfortably and work well when a patient bites or chews. In the lab, we carefully check how the teeth come together and make small adjustments to avoid any uneven pressure, which can cause discomfort or damage. Getting this right not only helps patients feel natural but also extends the life of the prosthetic by preventing wear and fractures over time.

What materials are commonly used in dental prosthetics, and how do you choose the appropriate one?

Interviewers ask this question to assess your understanding of dental prosthetic materials and your decision-making skills based on patient needs and case specifics. You should explain the common materials like acrylic resin, porcelain, metal alloys, and composite resins, and mention how you choose based on factors such as durability, aesthetics, allergies, cost, and adherence to safety guidelines.

Example: In dental prosthetics, materials like acrylic, porcelain, and metal alloys are often used. Choosing the right one depends on factors such as durability, aesthetics, and patient comfort. For example, porcelain is great for natural appearance, while metal alloys offer strength for crowns. Understanding each case’s needs and following established standards ensures we provide the best fit and function for the patient.
