CREST

CREST is CrestCo's real-time settlement system for UK and Irish shares and other corporate securities. CrestCo has provided settlement systems for government bonds and money market instruments in the UK since 1990.

CREST

The central securities depository for many British and Irish securities. In particular, it is used to settle gilts in the United Kingdom. Using CREST carries tax advantages for U.K. investors. It allows shares to be traded between investors without the physical certificates needing to change hands. Euroclear has owned it since 2002.

Crest

a paperless settlement system which was introduced in 1996 to cut the costs and speed up the completion of dealings on the UK STOCK MARKET. Under Crest, STOCK and SHARE transactions are recorded electronically, in contrast to the existing parallel system (TALISMAN) which involves the issue of settlement papers and share certificates. However, as with Talisman, investors will still receive a contract note from their broker to confirm their purchase or sale.

Combination of "Osteon" and "Colla Guide" resorbable membrane facilitates increasing efficacy of the treatment, preserving alveolar crest height and shape.
(a) For the patients with dentulous jaws, the insertion location of the installation was at the palatal top of the alveolar crest between the first and the second molars; for the patients with edentulous jaws, the insertion location of the installation was 5 mm to the palatal side from the point of the intersection of the vertical line going through the infraorbital foramen and the top of alveolar crest.
It is reasonable to assume that such residual alveolar crest would undergo more contraction compared with a 4-wall extraction socket defect when is left to heal spontaneously.

Conservative treatment of root fractures below the alveolar crest may require reduction of the displaced fragment immobilization and relief of the occlusion.
Then, intra-oral examination of the edentulous space showed a well managed space to symmetrically replace the missing right central incisor accord- ing to the left central incisor, a narrow alveolar crest indicating a horizontal bone loss at the site of the missing tooth.
The distance between the lower border of the artery and the alveolar crest (A), bone height from the sinus floor to the ridge crest (B), distance from the artery to the medial sinus wall (C), and the diameter and location of the artery were determined (Figure 1); occurrence of sinus septa and membrane thickening were also recorded from CBCT scans.
These materials help improve bone defects in AP fractures restoring the alveolar crest height and shape.
The periodontist evaluated each radiograph on the presence or absence of radiographic calculus, degree of periodontal involvement, and degree of osseous deformities in the alveolar bone inferior to the alveolar crest. For degree of periodontal involvement, the evaluation question asked, "Does the enclosed radiograph show evidence of bone loss in the anterior alveolar bone, as measured from the CEJ [cementoenamel junction] to the alveolar crest?" The periodontist evaluated for no bone loss (CEJ to alveolar crest = 1.5 mm), minimal bone loss (CEJ to alveolar crest 2-4 mm), moderate bone loss (CEJ to alveolar crest 5-7mm), or advanced bone loss (CEJ to alveolar crest 7 mm).
When the implantation site for the oblique bone surface (such as zygomatic alveolar crest, retromolar pad, external oblique ridge, etc.), the implanting nails may slide along the periosteum within the mucous membrane, without entering the cortical bone and slipping off.
