Summary
Resilient telescopic overdentures significantly improve chewing efficiency and maximum bite force in patients with atrophied mandibles compared to bar attachment systems.
Area of Science:
- Dental Implantology
- Prosthodontics
- Biomaterials Science
Background:
- Severely atrophied mandibles present challenges for conventional denture stability and function.
- Implant-retained overdentures offer improved outcomes but attachment system choice is critical.
- Evaluating chewing efficiency and bite force is essential for assessing prosthetic success.
Purpose of the Study:
- To compare chewing efficiency and maximum bite force (MBF) between resilient telescopic overdentures (TOD) and bar overdentures (BOD).
- To assess these parameters in patients with atrophied mandibles using implant-retained overdentures.
Main Methods:
- A crossover study involving ten participants with atrophied mandibles.
- Participants used conventional dentures (CD), BOD, and TOD sequentially.
- Chewing efficiency (unmixed fraction) and MBF were measured after 3 months of use for each prosthesis type.
Main Results:
- Both BOD and TOD significantly improved chewing efficiency and MBF compared to CD.
- TOD demonstrated significantly higher chewing efficiency and MBF than BOD.
- Chewing efficiency, measured by decreasing unmixed fraction, improved with increased chewing strokes.
Conclusions:
- Resilient telescopic attachments provide superior chewing efficiency and MBF compared to bar attachments for implant-retained overdentures in atrophied mandibles.
- TOD represent a promising treatment option for enhancing masticatory function in this patient population.

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...

The human tooth enables us to eat a variety of foods, speak clearly, and even aid in shaping our faces. Teeth are composed of various elements that work together. Here's a detailed look at the anatomy of a human tooth.
The Crown, Neck, and Root
The visible part of the tooth is referred to as the crown. It's covered by enamel, the hardest substance in the human body. The crown is uniquely shaped for each type of tooth, allowing for different functions such as cutting, tearing, or...
