Treatment Planning & Management Flashcards

A ceramist receives a prescription for a full-arch implant-supported ceramic bridge. Which treatment planning factor is uniquely important compared to tooth-supported bridgework?

Answer: The absence of periodontal ligament and proprioceptive feedback

Implants lack a periodontal ligament, eliminating proprioceptive feedback and increasing the risk of overloading ceramic restorations with excessive occlusal forces.

When treatment planning ceramic inlays versus full coverage crowns for posterior teeth, which factor most favors choosing an inlay?

Answer: Adequate remaining tooth structure with localized interproximal decay

Ceramic inlays are indicated when sufficient healthy tooth structure remains to support the restoration, preserving more natural tooth than a crown preparation.

Which smile design principle directly influences treatment planning for the number and size of ceramic veneers in the esthetic zone?

Answer: Golden proportion and tooth width-to-height ratio

The golden proportion (approximately 1:0.618) and ideal width-to-height ratios guide planning the number, width, and shape of veneers for a harmonious smile.

A patient with a history of ceramic fracture in a previous restoration presents for a new crown. Which treatment planning adjustment is most appropriate?

Answer: Investigate occlusal etiology, adjust occlusion, and select a higher-strength ceramic

Recurrent ceramic fracture suggests an unaddressed occlusal problem; both the cause and the material selection must be addressed to prevent repeat failure.

When planning ceramic restorations for a patient undergoing orthodontic treatment, when is the ideal time to take final impressions?

Answer: After a sufficient stabilization/retention period post-orthodontics

Teeth continue to shift after orthodontic appliance removal; final impressions should be taken only after a retention period ensures tooth positions are stable.

A treatment plan calls for ceramic veneers on teeth #8 and #9 to correct diastema closure. What pre-treatment planning consideration is essential?

Answer: Confirm the diastema is of cosmetic concern only and not caused by a pathologic frenum or tongue thrust

Diastemas caused by a low frenal attachment or tongue thrust will recur unless the underlying cause is corrected before veneer placement.

Which patient medical history finding requires a treatment planning modification when scheduling long ceramic restoration appointments?

Answer: Controlled hypertension requiring scheduled medication timing

Patients with hypertension may need appointments timed around medication schedules to maintain stable blood pressure during lengthy dental procedures.
