Top 10 Questions for Prosthodontist Interview

1. What are the key considerations for determining the retention and stability of a complete denture?

In determining the retention and stability of a complete denture, the following key considerations must be taken into account:

• Anatomic factors: Ridge form, alveolar bone height, and the presence of undercuts.
• Physiologic factors: Salivary flow, muscle tone, and the patient’s ability to create a seal.
• Materials: The type of denture base material, the design of the denture, and the fit of the denture.
• Impression techniques: The accuracy of the impression and the relationship between the denture and the underlying tissues.

2. Describe the various types of dental implants used in prosthodontics and their clinical applications.

Types of Dental Implants

• Root form implants: These implants are shaped like the roots of natural teeth and are placed in the jawbone.
• Subperiosteal implants: These implants are placed on the surface of the jawbone, beneath the periosteum.
• Transosteal implants: These implants are placed through the jawbone and protrude through the oral mucosa.

Clinical Applications

• Root form implants: Used to support single crowns, bridges, and overdentures.
• Subperiosteal implants: Used to support overdentures in patients with severely resorbed alveolar ridges.
• Transosteal implants: Used to support overdentures in patients with severely resorbed alveolar ridges and poor bone quality.

3. Discuss the principles of occlusal design in prosthodontics and the importance of achieving a stable and functional occlusion.

The principles of occlusal design in prosthodontics aim to create a stable and functional occlusion that allows for proper chewing function, minimizes wear and tear on the teeth, and maintains the health of the temporomandibular joint. Key principles include:

• Balanced occlusion: Even distribution of forces on the teeth during all mandibular movements.
• Cusp-fossa relationship: The cusps of the maxillary teeth should fit into the fossae of the mandibular teeth, providing interdigitation and preventing lateral forces.
• Anterior guidance: The anterior teeth guide the mandible during protrusive and lateral movements, preventing posterior interferences.

4. Describe the different techniques for fabricating porcelain-fused-to-metal (PFM) crowns and bridges.

Techniques

• Conventional PFM: Metal substructure is cast and then veneered with porcelain.
• Pressed PFM: Porcelain is pressed onto a prefabricated metal substructure.
• CAD/CAM PFM: Metal substructure is designed and milled using CAD/CAM technology, and then veneered with porcelain.

Steps

• Preparation: Tooth preparation for the crown or bridge.
• Impression: Taking an impression of the prepared teeth.
• Fabrication: Creating the metal substructure and veneering with porcelain.
• Cementation: Cementing the crown or bridge to the prepared teeth.

5. Discuss the advantages and disadvantages of using implant-supported overdentures compared to conventional dentures.

Advantages

• Improved retention and stability.
• Reduced bone resorption.
• Enhanced chewing ability.
• Improved patient comfort and satisfaction.

Disadvantages

• Higher cost.
• Surgical procedure required for implant placement.
• Potential for implant failure.
• Maintenance and repair requirements.

6. Explain the concept of the “neutral zone” in complete denture fabrication and discuss its significance.

The “neutral zone” in complete denture fabrication refers to the area between the maxillary and mandibular dentures where there is no contact between the teeth. This zone is significant because:

• Prevents overclosure: The neutral zone limits the vertical closure of the dentures, preventing overclosure and strain on the supporting tissues.
• Facilitates phonetics: The neutral zone allows for freedom of movement of the tongue and lips, improving speech and pronunciation.
• Improves comfort: By eliminating unnecessary contact between the dentures, the neutral zone reduces discomfort and pressure on the oral tissues.

7. Describe the clinical steps involved in the fabrication of a maxillary immediate denture.

Steps

• Pre-extraction impression: Taken before tooth extraction.
• Tooth extraction: Extraction of the remaining teeth.
• Immediate impression: Taken immediately after tooth extraction.
• Fabrication: The denture is fabricated based on the immediate impression.
• Insertion: The denture is inserted immediately after extraction.

Benefits

• Preserves facial aesthetics.
• Reduces pain and discomfort.
• Maintains function and speech.

8. Discuss the different methods for managing temporomandibular joint (TMJ) disorders in prosthodontics.

Methods

• Occlusal adjustment: Correcting the occlusion to reduce stress on the TMJ.
• Splint therapy: Using occlusal splints to reposition the mandible and reduce muscle tension.
• Pharmacological therapy: Prescribing medications to manage pain and inflammation.
• Physical therapy: Implementing exercises to improve range of motion and reduce muscle pain.

9. Describe the role of advanced imaging techniques, such as cone beam computed tomography (CBCT), in prosthodontics.

CBCT is a valuable tool in prosthodontics due to its ability to:

• Provide 3D images of the jaws: This allows for precise evaluation of bone anatomy, implant placement, and surgical planning.
• Assess bone quality and quantity: CBCT helps determine the suitability of a patient for implant placement and the type of implant required.
• Diagnose TMJ disorders: CBCT can reveal the position of the condyles and the integrity of the joint structures.
• Evaluate the fit of dentures and implants: By superimposing CBCT images with digital scans of dentures or implants, the accuracy of the fit can be assessed.

10. Discuss the ethical considerations and responsibilities of a prosthodontist.

• Patient autonomy: Respecting the patient’s right to make informed decisions about their treatment.
• Confidentiality: Maintaining the privacy of patient information.
• Professionalism: Adhering to ethical guidelines and maintaining professional conduct.
• Continuing education: Staying up-to-date with advancements in prosthodontics through continuing education.
• Referrals: Appropriately referring patients to other specialists when necessary.

Prosthodontists are highly specialized dentists who focus on the restoration and replacement of damaged or missing teeth. They work closely with patients to develop treatment plans that meet their individual needs and goals. Some of the key job responsibilities of a Prosthodontist include:

1. Diagnosis and Treatment Planning

Prosthodontists are responsible for diagnosing and treating a wide range of dental problems, including missing teeth, damaged teeth, and jaw problems. They work closely with patients to develop a treatment plan that meets their individual needs and goals.

• Evaluate patients’ dental health and oral function.
• Review medical and dental history, and perform oral examinations.
• Develop comprehensive treatment plans, including options for restoring function, aesthetics, and overall oral health.

2. Restorative Dentistry

Prosthodontists are skilled in restoring damaged teeth and replacing missing teeth. They use a variety of techniques to create custom-made prosthetics, such as crowns, bridges, dentures, and implants.
