Summary
The shortened dental arch (SDA) concept offers a cost-effective solution for older adults keeping their teeth. Proper case selection and treatment planning are crucial for long-term oral function in these patients.
Area of Science:
- Geriatric Dentistry
- Restorative Dentistry
- Dental Prosthetics
Background:
- An increasing number of older adults retain their natural teeth.
- Many older adults with remaining teeth have extensive dental work and disease.
- Removable partial dentures are often refused by this demographic.
Purpose of the Study:
- To evaluate the shortened dental arch (SDA) concept for managing older, partially dentate adults.
- To identify critical treatment planning issues for SDA.
- To outline strategies for avoiding occlusal instability in SDA patients.
Main Methods:
- Review of clinical cases and treatment planning considerations for SDA.
- Analysis of factors influencing long-term success in SDA.
- Discussion of strategies to prevent occlusal instability.
Main Results:
- The SDA concept is a potentially cost-effective management approach.
- Case selection is critical for successful SDA implementation.
- Long-term preservation of dentition may not be feasible for all patients.
Conclusions:
- The shortened dental arch concept, when appropriately applied, can ensure satisfactory long-term oral function for partially dentate adults.
- Careful treatment planning is essential for successful outcomes.

In brick wall construction, supporting structures are crucial for openings like windows and doors to maintain the integrity and support the weight of the wall above. These supports include lintels, corbels, and arches, each serving specific structural purposes.
Lintels are primary supports used to span openings and can be crafted from materials such as reinforced concrete, steel-reinforced brick masonry, or simple steel angles. These are straightforward to install and are typically concealed...

01:15Teeth
The formation of teeth, also known as odontogenesis, is a complex process that begins in utero, around the sixth week of embryonic development. There are three stages to this process: the bud stage, the cap stage, and the bell stage.
In the bud stage, the tooth germ (an aggregation of cells) starts to form in the developing jawbone. During the cap stage, the tooth germ differentiates into enamel organ, dental papilla, and dental sac, which will later develop into the tooth's enamel, dentin and...
