Summary
This 15-year study found that extensive mandibular cantilever fixed partial dentures showed mixed success, with low maintenance costs. They may offer a viable solution for patients with severely reduced dentition struggling with removable dentures.
Area of Science:
- Dentistry
- Prosthodontics
- Dental Materials
Background:
- Assessing the long-term efficacy of extensive mandibular cantilever fixed partial dentures (CFPDs) in patients with severely reduced dentition.
- Evaluating the success rates, complications, and maintenance costs of CFPDs compared to other prosthetic options.
Observation:
- Twelve patients with complete maxillary dentures received 12-unit mandibular CFPDs, followed for 15 years.
- Success rates varied, with 4 dentures failing, 4 remaining functional, and 4 patients dying with their prostheses in situ.
- The most frequent complications were endodontic issues and post retention loss; caries and periodontal disease were infrequent.
Findings:
- Four out of twelve mandibular cantilever fixed partial dentures (CFPDs) demonstrated successful long-term function (15 years).
- Endodontic complications and loss of post retention were the primary failure modes, while caries and periodontal disease were rare.
- Maintenance costs for CFPDs were notably low, even when compared to implant-supported restorations.
Implications:
- Extensive mandibular CFPDs can be a durable and cost-effective treatment option for specific patient groups.
- This prosthetic approach may benefit patients with highly reduced dentition and poor tolerance for removable dentures.
- Further research into optimizing CFPD design and patient selection could enhance long-term predictability and success rates.

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...

01:21Tooth Anatomy
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 grinding food.
