Summary
Posterior metal ceramic crowns demonstrate high long-term survival and success rates over 20 years, proving reliable for dental restorations in private practice settings.
Area of Science:
- Dental Materials Science
- Prosthodontics
- Clinical Dentistry
Background:
- Posterior metal ceramic crowns are a common dental restoration.
- Long-term clinical performance data is essential for treatment evaluation.
Purpose of the Study:
- To evaluate the 20-year clinical performance of posterior metal ceramic crowns.
- To gather long-term data on survival and technical success rates.
Main Methods:
- Prospective practice-based study involving 10 private practitioners.
- Two groups: single crowns (190) and retainer crowns (276).
- Follow-up period of 20 years.
Main Results:
- 20-year survival rates: 78.8% (single crowns) and 67.8% (retainer crowns).
- 20-year technical success rates: 74.2% (single crowns) and 62.9% (retainer crowns).
- Veneering ceramic defects were frequent but rarely led to crown loss.
Conclusions:
- Posterior metal ceramic crowns exhibit high survival and success rates over 20 years.
- These restorations are a reliable treatment option in private practice.
- Long-term data supports the continued use of metal ceramic crowns.

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...

Bonding in Metals
52.5K
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”.

Metallic Solids
20.7K
Metallic solids such as crystals of copper, aluminum, and iron are formed by metal atoms. The structure of metallic crystals is often described as a uniform distribution of atomic nuclei within a “sea” of delocalized electrons. The atoms within such a metallic solid are held together by a unique force known as metallic bonding that gives rise to many useful and varied bulk properties.
All metallic solids exhibit high thermal and electrical conductivity, metallic luster, and malleability....

Alkali Metals
24.8K
Group 1 elements are soft and shiny metallic solids. They are malleable, ductile, and good conductors of heat and electricity. The melting points of the alkali metals are unusually low for metals and decrease going down the group, while the density increases going down the group with the exception of potassium (Table 1).

Metal-Ligand Bonds
24.3K
The hemoglobin in the blood, the chlorophyll in green plants, vitamin B-12, and the catalyst used in the manufacture of polyethylene all contain coordination compounds. Ions of the metals, especially the transition metals, are likely to form complexes.
In these complexes, transition metals form coordinate covalent bonds, a kind of Lewis acid-base interaction in which both of the electrons in the bond are contributed by a donor (Lewis base) to an electron acceptor (Lewis acid). The Lewis acid in...

Properties of Transition Metals
29.9K
Transition metals are defined as those elements that have partially filled d orbitals. As shown in Figure 1, the d-block elements in groups 3–12 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is partially occupied before the f orbitals.
