The approach comprises two steps： （1） fit a partial thin-plate smoothing spline with orography and reanalysis data as explanatory variables to ground-based observations for estimating a trend surface; （2） apply a simple kriging procedure to the residual for trend surface correction. The proposed approach is applied to observations collected at approximately 700 stations over China's Mainland. The generated forcing fields are compared with the corresponding components of the National Centers for Environmental Predic- tion （NCEP） Climate Forecast System Reanalysis dataset and the Princeton meteorological forcing dataset. The comparison shows that, both within the station network and within the resolutions of the two gridded datasets, the interpolation errors of the proposed approach are markedly smaller than the two gridded datasets.展开更多
牙槽骨是牙医学的基础,牙槽骨缺损的修复与再生和口腔种植、口腔正畸、牙周及口腔修复等亚专业学科关系密切。因此,对牙槽骨进行有效的修复与重建具有重要的临床意义和社会效益。随着引导骨再生(guide bone regeneration,GBR)技术的发展...牙槽骨是牙医学的基础,牙槽骨缺损的修复与再生和口腔种植、口腔正畸、牙周及口腔修复等亚专业学科关系密切。因此,对牙槽骨进行有效的修复与重建具有重要的临床意义和社会效益。随着引导骨再生(guide bone regeneration,GBR)技术的发展,基于以"稳定为核心"的牙槽骨修复与再生理念,一种全新的骨增量技术快速发展,且在临床上获得了有效验证,即基于帐篷钉技术的骨增量方案。该技术具有技术敏感性低、操作简单、手术时间短及费用低等特点。另外,可以单纯应用生物医用材料,在不需要自体骨参与的情况下完成牙槽骨严重缺损的修复与再生。因此,该项技术获得了越来越多医师和患者的青睐。但目前广大医师对如何正确将其有效用于临床仍面临诸多困难,如正规手术操作流程、帐篷钉放置的位置及方向、放置可吸收生物膜与放帐篷钉的顺序以及安放配钉的位点等。鉴于此,本项目组基于临床手术操作流程,撰写了帐篷钉技术在牙槽骨修复与再生中临床应用操作规范,旨在为广大口腔医师在应用该项技术时提供一定的参考和依据,并对其临床推广应用起到积极作用。展开更多
