Summary
Restoring visible mandibular anterior teeth can be challenging and costly. This study presents a cost-effective method using full coverage crowns and resin-bonded bridges for missing teeth.
Area of Science:
- Dentistry
- Restorative Dentistry
- Prosthodontics
Background:
- Aesthetic restorations typically focus on visible anterior teeth.
- Mandibular anterior bridges pose challenges due to tooth size and visibility.
- High costs of traditional fixed partial dentures limit patient access.
Purpose of the Study:
- To describe a cost-effective technique for restoring missing mandibular anterior teeth.
- To present a combined approach of full coverage crowns and resin-bonded fixed bridges.
Main Methods:
- Fabrication of full coverage crowns on natural teeth.
- Construction of a resin-bonded fixed bridge to replace missing teeth.
- Integration of crowns and bridge for a combined restoration.
Main Results:
- Successful restoration of missing mandibular anterior teeth.
- A cost-effective alternative to traditional fixed partial dentures.
- Improved aesthetics and function for patients.
Conclusions:
- The described technique offers a viable, economical solution for mandibular anterior tooth replacement.
- This approach addresses the challenges of size, visibility, and cost in aesthetic restorations.
- It provides a practical option for patients unable to afford conventional treatments.

Crown Ethers
6.1K
Crown ethers are cyclic polyethers that contain multiple oxygen atoms, usually arranged in a regular pattern. The first crown ether was synthesized by Charles Pederson while working at DuPont in 1967. For this work, Pedersen was co-awarded the 1987 Nobel Prize in Chemistry. Crown ethers are named using the formula x-crown-y, where x is the total number of atoms in the ring and y is the number of ether oxygen atoms. The term 'crown' refers to the crown-like shape that these ether molecules...

Teeth
1.8K
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...

Bond Energies and Bond Lengths
31.5K
Stable molecules exist because covalent bonds hold the atoms together. The strength of a covalent bond is measured by the energy required to break it, that is, the energy necessary to separate the bonded atoms. Separating any pair of bonded atoms requires energy — the stronger a bond, the greater the energy required to break it.

Peptide Bonds
82.9K
A peptide bond covalently attaches amino acids through a dehydration reaction. One amino acid's carboxyl group and another amino acid's amino group combine, releasing a water molecule. The resulting bond is the peptide bond. The products that such linkages form are peptides. As more amino acids join this growing chain, the resulting chain is a polypeptide. Each polypeptide has a free amino group at one end. This end has the N-terminal, or the amino-terminal, and the other end has a free...

Metallic bonds are formed between two metal atoms. A simplified model to describe metallic bonding has been developed by Paul Drüde called the “Electron Sea Model”.

Overview
When atoms gain or lose electrons to achieve a more stable electron configuration they form ions. Ionic bonds are electrostatic attractions between ions with opposite charges. Ionic compounds are rigid and brittle when solid and may dissociate into their constituent ions in water. Covalent compounds, by contrast, remain intact unless a chemical reaction breaks them.
Opposing Charges Hold Ions Together in Ionic Compounds
Ionic bonds are reversible electrostatic interactions between ions...
