His friends are not happy with him because he always turns down their invitations () ill health.
A、on the ground of
B、on the strength of
C、in view of
D、by means of
A.Summarize published clinical trials on bonded oxide ceramic restorations and correlate their results with that of laboratory bond strength testing using the same bonding methods as in the clinical trials.
B. Despite a huge number of published laboratory bonding studies on dental oxide ceramics clinical long-term studies on resin bonded oxide ceramic restorations are rare. The purpose of this review is to present the best available clinical evidence for successful bonding of dental oxide ceramic restorations.
C. Replicate the previous studies.
D.Summarize the huge variety of bonding methods used on dental oxide ceramics and their results in laboratory bond strength testing
A.Path loss
B.Path loss, minus antenna gain
C.Path loss, minus antenna gain, plus feeder loss
D.Path loss, minus antenna gain plus feeder and combiner losses
E.There is no difference
A. There are no controlled clinical trials showing that air-abrasion affects the clinical outcome of oxide ceramic restorations negatively.
B.There is still a controversy whether air-abrasion alters the strength of zirconia ceramic restorations.
C. On densely sintered zirconia clinically no durable bonding was achieved using silica-coating, silane application and using a MDP containing luting resin.
D.However, despite the use of retentive preparation design a debonding rate of 13.3% occurred within the first 53 months.
B.SWOT即检查分析企业自己、竞争对手以及大环境中的优势(Strength)、劣势(Weakness)、机会(Opportunity)和威胁(Threat)
C.SWOT可以使企业将问题按轻重缓急分类,明确每一阶段所急需解决的问题
D.SWOT只针对大客户才使用
A.This article will not attempt to replicate the above mentioned reviews but will summarize published clinical trials on bonded oxide ceramic restorations and correlate their results with that of laboratory bond strength testing using the same bonding methods as in the clinical trials.
B.The authors of this systematic review concluded, that promising laboratory test results still need to be confirmed by clinical studies before clinical recommendation could be given.
C.Clinical trials with resin-bonded restorations that had no or only limited mechanical retention and were made from alumina or zirconia ceramic were identified using an electronic search in PubMed database.
D.The purpose of this review is to present the best available clinical evidence for successful bonding of dental oxide ceramic restorations.
