THE DOUBLE BELT SYSTEM FOR TREE CROWN STABILIZATION
Arboricultural Journal, 1993Summary As tree crown failure along roadsides is an unacceptable hazard to both traffic and pedestrians, a new belt system for crown stabilization has been developed. The double belt “System Osnabruck” combines a stronger retaining belt, which carries the load and is linked to the bracing cable, and a weaker fastening belt, which is tightened loosely ...

Retention force of removable partial dentures with different double crowns
Clinical Oral Investigations, 2017The aim of the study was to compare the retentive behaviors of double crowns with different designs and material compositions before and after artificial aging.Six pairs of double crowns were fabricated: telescopic crowns 0° made of high-noble metal (group A) or non-precious metal (group B), telescopic zirconia copings with secondary crowns made of ...

Attachments and Double Crown Systems for Removable Partial Dentures
2016There is lack of evidence-based knowledge to dominate clinical decision making about attachments for RPDs. Even though the use of attachments in clinical dentistry is very regular, selecting the appropriate attachment for a particular case can sometimes be a challenge.

Synthesis and complexation behaviour of a double-armed crown thioether ligand
Inorganica Chimica Acta, 1994Abstract The novel macrocycle 3,11-bis[4-(n-hexyloxy)benzoyloxy]- 1,5,9,13-tetrathiacyclohexadecane (2) was obtained as a mixture of cis and trans isomers by reaction of 1,5,9,13-tetra-thiacyclohexadecane- 3,11-diol (1) (cis and trans) and 4-(n- hexyloxy)benzoyl chloride.

Parameters affecting retentive force of electroformed double-crown systems
Clinical Oral Investigations, 2009The aim of this study was to determine the values of retentive forces of double crowns. The effect of the abutment height, the material of the inner crown, and the taper were evaluated. Sixty inner crowns each were fabricated from zirconia and a gold alloy having three different abutment heights (5, 7, and 9 mm) and two different tapers (0 degrees and ...

This article describes the concept of the Marburg double crown system (MDC system) in the treatment of partially edentulous patients. Long-term success is assessed by a review of patient records.Double crowns with clearance fit are used to retain tooth-, mucosa-, and implant-supported removable partial dentures (RPD).
