What is the recommended treatment for replacing four mandibular incisors?
What is the recommended treatment for replacing four mandibular incisors?
- Using over-contoured restorations on the mandibular incisors
- Leaving a lone incisor in place to avoid complications
- Including the first premolars in the fixed partial denture
- Simple fixed partial denture with retainers on each canine (correct)
Why is it generally not necessary to include the first premolars in the fixed partial denture for replacing mandibular incisors?
Why is it generally not necessary to include the first premolars in the fixed partial denture for replacing mandibular incisors?
- First premolars are prone to periodontal disease
- To improve esthetics of the replacement teeth
- To simplify the design and fabrication of the fixed partial denture (correct)
- First premolars are not strong enough to support the denture
What complication can arise if a lone mandibular incisor remains in place during the fabrication of a fixed partial denture?

- Compromised esthetics of the replacement teeth
- Increased stability of the denture
- Difficulty in tooth preparation (correct)
- Improved long-term result of the denture

Study Notes
Replacing Mandibular Incisors
- The recommended treatment for replacing four mandibular incisors is a five-unit fixed partial denture, extending from one canine to the other.
Importance of Exclusion
- It is generally not necessary to include the first premolars in the fixed partial denture for replacing mandibular incisors because the canines provide sufficient support and retention.
Complication of Lone Mandibular Incisor
- If a lone mandibular incisor remains in place during the fabrication of a fixed partial denture, it can lead to the complication of tooth movement, making it difficult to achieve a proper fit.
Avoiding Over-Contoured Restorations
- Over-contoured restorations should be avoided on mandibular incisors because they can lead to periodontal problems and make oral hygiene difficult.
Key Consideration for Restoration
- When dealing with mandibular incisors during restoration, it is particularly important to maintain a harmonious occlusal plane to ensure proper function and aesthetics.
