Maxilla Resorption in Dentistry

Questions and Answers

How does the density of bone affect the rate of resorption?

Lower density results in slower resorption.

Bone density has no effect on resorption rate.

Higher density slows down the rate of resorption. (correct)

Higher density leads to faster resorption.

What is the relationship between bone resorption and the amount of bone available?

More bone leads to increased resorption rates.

More bone causes resorption rates to decrease. (correct)

Less bone available decreases the resorption rate.

Resorption remains constant regardless of bone amount.

What happens to bone resorption rates as bone density increases?

They remain unchanged.

They gradually decrease. (correct)

They increase sharply.

They fluctuate erratically.

Study Notes

Maxilla Resorption

Maxilla resorbs upward and inward, decreasing in size due to the roots' direction and inclination of teeth.
Alveolar process accompanies this process, affecting overall oral structure.

Quality of Bone

Denser bone exhibits slower resorption rates, allowing more bone to be resorbed over time.
Connection to health issues like diabetes may relate indirectly to bone resorption.

Prosthetic Factors Influencing Stability

Broad-area coverage reduces force per unit area, improving denture support.
Reducing the number of dental units aids in minimizing stress on remaining structures.
Decreased bucco-lingual width of teeth contributes to overall denture balance.
Improved tooth forms lower the force necessary to mash food, enhancing functionality.

Design Considerations for Dentures

Avoiding inclined planes minimizes the risk of denture dislodgement and shear stresses.
Centralization of occlusal contacts enhances denture stability and optimizes compressive forces.
Providing adequate tongue space increases stability during speech and eating.
Ensuring adequate inter-occlusal distance during rest jaw relation diminishes frequency and duration of tooth contacts.
An occlusal table that is narrow is beneficial for better contact distribution and stability.
