In treatment planning ceramic onlays for a patient with an existing large MOD composite, which clinical finding most supports upgrading to a full coverage crown instead?
Answer: Cuspal flexure, cracked cusp syndrome symptoms, or remaining wall thickness less than 2 mm
Thin remaining walls under 2 mm or evidence of cuspal cracking indicate insufficient structure for an onlay and favor a full-coverage crown to protect against fracture.
A patient asks for ceramic veneers on all maxillary teeth but has a deep overbite. What is the primary treatment planning concern?
Answer: Mandibular incisal edges will contact and potentially fracture the palatal surfaces of the maxillary veneers
A deep overbite creates heavy palatal contact on maxillary anteriors, making ceramic veneers prone to fracture unless the occlusion is corrected or the treatment plan is modified.
Which communication tool is considered the gold standard for conveying the treatment plan's esthetic goals between the clinician and dental ceramist?
Answer: A comprehensive laboratory prescription paired with intraoral photographs, shade tabs, and a diagnostic wax-up
A detailed lab prescription combined with calibrated photographs, shade documentation, and a diagnostic wax-up provides the ceramist with all information needed for accurate fabrication.
A ceramist notes that the working cast shows insufficient occlusal reduction on a molar preparation prescribed for a full-coverage ceramic crown. What is the appropriate management response?
Answer: Notify the clinician and return the case for additional preparation before proceeding
Insufficient preparation depth compromises ceramic strength and esthetics; the ceramist must communicate this to the clinician for re-preparation before proceeding.
When treatment planning ceramic restorations for a patient with acid erosion, which preventive management step must be confirmed before fabrication?
Answer: The source of acid (dietary, GERD, or bulimia) has been identified and controlled
Continuing acid erosion will destroy the ceramic restorations over time; the etiology must be diagnosed and controlled before definitive restorations are placed.
Which articulator mounting procedure is most appropriate when treatment planning full-arch ceramic rehabilitation to ensure accurate occlusal relationships?
Answer: Using a centric relation record and facebow transfer to mount casts on a semi-adjustable articulator
A facebow transfer reproduces the patient's hinge axis relationship to the condyles, and a CR record ensures casts are mounted in the reproducible terminal hinge position for accurate occlusal planning.
In the context of ceramic treatment planning, what does the term 'biological width' refer to and why is it clinically significant?
Answer: The combined width of junctional epithelium and connective tissue attachment that must not be violated by restoration margins
Violation of the biological width (approximately 2 mm) by subgingival margins causes chronic inflammation and bone loss, compromising the long-term prognosis of ceramic restorations.
