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:
- Growing population of older adults retaining natural teeth.
- Challenges in managing partially dentate older adults, including denture refusal and high prevalence of dental disease.
- Need for cost-effective management strategies for 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 associated with SDA.
- To outline strategies for avoiding occlusal instability in patients with SDA.
Main Methods:
- Review of literature and clinical case considerations regarding the SDA concept.
- Analysis of treatment planning factors critical for SDA success.
- Development of treatment strategies to ensure occlusal stability.
Main Results:
- The SDA concept is a viable, cost-effective approach for managing older adults with shortened dental arches.
- Careful case selection is paramount for the long-term success of SDA.
- Specific treatment strategies can mitigate risks of occlusal instability.
Conclusions:
- The shortened dental arch concept, when appropriately applied, ensures satisfactory long-term oral function for partially dentate adults.
- Effective treatment planning is key to successful outcomes with SDA in geriatric patients.

01:20Spanning Openings in Brick Walls
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...
