Mixed Deck — All CCA Topics Flashcards

What is the first step in developing a treatment plan for a facial prosthesis?

Answer: Clinical assessment and patient consultation

A comprehensive clinical evaluation identifies patient needs, anatomical considerations, and functional goals.

Which layer of the ocular prosthesis is responsible for giving the iris its depth and three-dimensional appearance?

Answer: The hand-painted iris lamination between clear acrylic layers

The hand-painted iris is laminated between layers of clear acrylic to create a realistic depth effect in the finished prosthesis.

A patient who initially coped well with facial disfigurement begins showing signs of depression two years after prosthetic fitting. This pattern is best explained by:

Answer: Psychological adjustment being a dynamic, ongoing process that can shift over time

Psychological adjustment to disfigurement is not a fixed outcome; life events and changed circumstances can trigger renewed distress even after initial successful adaptation.

Intrinsic coloring of a silicone prosthesis refers to:

Answer: Incorporating pigments into the silicone base before vulcanization

Intrinsic coloring embeds pigments within the silicone mass so color is durable and cannot be rubbed off, unlike extrinsic surface painting.

In craniofacial anaplastology, the term 'undercut' in mold making refers to:

Answer: A concave area in the impression or model that would trap a rigid mold material and prevent removal

Undercuts are geometric concavities where rigid mold material would lock, requiring blocking out with wax or using flexible impression materials before pouring stone.

When fabricating a bar for implant-retained auricular prosthetics using CAD/CAM, which material is most commonly milled for the bar framework?

Answer: Pure commercially pure titanium or titanium alloy (Ti-6Al-4V)

Titanium and its alloys are the most commonly milled bar materials due to biocompatibility, corrosion resistance, and favorable strength-to-weight ratio in CAD/CAM workflows.

Which communication technique is MOST effective when a patient is emotionally overwhelmed and tearful during a prosthetic consultation?

Answer: Offer a tissue, pause, and use silence to allow emotional expression

Allowing silence and offering simple comfort signals empathy and creates space for the patient to process emotions before clinical discussion resumes.

Radiation therapy to the head and neck prior to craniofacial implant placement is a significant risk factor primarily because it causes:

Answer: Hypovascular, hypocellular, hypoxic bone (osteoradionecrosis risk)

Radiation damages the vasculature and cellular elements of bone, producing a hypoxic-hypovascular-hypocellular environment that impairs osseointegration and raises osteoradionecrosis risk.

When is it appropriate for an anaplastologist to terminate the therapeutic relationship with a patient?

Answer: When the patient is abusive toward staff and appropriate warnings have been given

Therapeutic relationships may be terminated when patients are abusive after due warnings, provided adequate notice and transfer of care are arranged.

When matching a prosthesis to sun-tanned skin, the anaplastologist should:

Answer: Match the untanned baseline skin tone to accommodate seasonal color changes

Matching the patient's baseline untanned skin tone ensures the prosthesis remains aesthetically appropriate year-round as seasonal tan fades.

The 'snap set' characteristic of alginate is clinically significant because it:

Answer: Reduces patient discomfort by minimizing the set wait period

Alginate's rapid, abrupt gelation minimizes the time patients must remain motionless, which is especially important for patients with limited cooperation.

A patient returns with a cracked acrylic orbital prosthesis framework. What material is typically used to repair cracks in acrylic prosthetic bases?

Answer: Autopolymerizing (self-curing) acrylic resin

Autopolymerizing acrylic repair resin chemically bonds to existing acrylic bases and provides a durable, color-matched repair for cracked prosthetic frameworks.

Why is confidentiality important in patient care?

Answer: To ensure trust and legal compliance

Protecting personal health information builds trust and complies with legal and ethical standards.

An anaplastologist is matching a patient with vitiligo. Which technique best addresses the high-contrast hypopigmented patches?

Answer: Layering translucent tints over a base color with stippling for selective depigmentation effects

Selective translucent layering and stippling techniques allow the anaplastologist to replicate patchy depigmentation patterns characteristic of vitiligo.

In Implant-Retained Prosthetics, what is the FIRST step a CCA professional should take when encountering a new case or situation?

Answer: Conduct a comprehensive assessment and gather all relevant information

In Implant-Retained Prosthetics, a thorough initial assessment ensures all relevant factors are identified before deciding on an appropriate course of action. This systematic approach is fundamental to Certified Clinical Anaplastologist practice.

When a conflict arises between standard procedures and a unique situation in Auricular & Nasal Reconstruction, what should a CCA professional prioritize?

Answer: Safety and ethical obligations while seeking expert consultation

Safety and ethics always take priority in Auricular & Nasal Reconstruction. When standard procedures don't adequately address a unique situation, consulting with experienced colleagues or supervisors ensures both safety and professional standards are maintained.

A patient with a terminal diagnosis requests an elaborate prosthesis that will likely outlast the patient by many years. How should the anaplastologist approach this ethically?

Answer: Discuss the patient's goals, quality-of-life priorities, and treatment options openly

Open discussion of goals and quality-of-life priorities respects patient autonomy while ensuring treatment decisions are well-informed.

In a magnetic retention system for an auricular prosthesis, the magnets are usually embedded in the:

Answer: Prosthesis base and the corresponding bar or cap on the abutment

One magnet set is encapsulated within the silicone prosthesis base and the opposing magnets are housed in keeper attachments on the implant bar or individual abutments.

What is the primary function of adding a gauze mesh or burlap reinforcement within a plaster mold?

Answer: To increase mold strength and prevent cracking during processing

Fiber reinforcement embedded in the mold body resists fracture forces during clamping and demold, extending mold lifespan.

Which platinum catalyst system is most commonly used to vulcanize addition-cured (condensation-free) silicone for facial prostheses?

Answer: Platinum-based addition catalyst at body or room temperature

Platinum-catalyzed addition-cure silicones produce no by-products, offer excellent biocompatibility, and cure at room or mild elevated temperatures used in anaplastology.
