Abstract

Introduction

The present study aimed to evaluate and to compare the influence of anatomical variables such as sinus width (SW), inner maxillary sinus contour length (IMSCL), and residual ridge height (RRH) on new bone formation (%NBF) for deproteinized porcine (DPBM) and bovine bone mineral (DBBM) used for lateral window sinus augmentation (LWSA) grafting.

Material and Methods

For LWSA groups grafted either with DPBM (n = 10) or DBBM (n = 13) a linear- as well as a multivariate-regression analysis was conducted between measured %NBF and radiographically retrospectively assessed anatomical variables (SW/IMSCL/RRH). Correlations as well as regression coefficients (R²) were calculated, evaluating the influence of anatomical variables on %NBF with differentiation between both xenogenic graft materials used.

Results

With no differences for patient-epidemiologic data, for anatomical variables as well as for surgical- and patient-related risk factors, comparison between the two LWSA groups was possible. The linear-regression analysis provided significant correlations between histomorphometrically evaluated %NBF and SW (DPBM: r = −0.660, p = 0.038; DBBM: r = −0.614, p = 0.026) as well as between %NBF and IMSCL (DPBM: r = −0.737; p = 0.015, DBBM: r = −0.573, p = 0.041), but not for RRH. Between SW/IMSCL/RRH and %NBF, regression-coefficients-(R²) of 0.435/0.543/0.258 using DPBM and R² of 0.377/0.328/0.053 using DBBM represented evidently higher influences of anatomical structures when porcine graft material was applied. The multivariate-regression analysis confirmed the different influence between various xenogenic graft materials on % NBF as well with a pronounced effect for porcine material (DPBM: R² = 0.591 [59.1%] vs. DBBM: R² = 0.314 [31.4%]).

Conclusion

In LWSA, anatomical structures such as SW and IMSCL significantly affect new bone formation, though with varying effects for different xenogenic (porcine vs. bovine) bone mineral graft materials used.

上颌窦尺寸对不同移植材料侧窗窦增强术中新骨形成影响的回顾性研究

本研究旨在评估和比较去蛋白猪（DPBM）和牛骨矿物质（DBBM）在侧窗窦隆（LWSA）移植术中，窦宽（SW）、内颌窦轮廓长度（IMSCL）和残余脊高（RRH）等解剖学变量对新骨形成（%NBF）的影响。材料和方法对于移植DPBM （n = 10）或DBBM （n = 13）的LWSA组，在测量的%NBF和放射学回顾性评估的解剖变量（SW/IMSCL/RRH）之间进行线性和多变量回归分析。计算相关性和回归系数（R2），评估解剖变量对两种异种移植物材料差异百分比NBF的影响。结果在患者流行病学数据、解剖变量以及手术和患者相关危险因素没有差异的情况下，两个LWSA组之间可以进行比较。线性回归分析显示，组织形态计量学评估的%NBF与SW (DPBM: r = - 0.660, p = 0.038；DPBM: r = - 0.614, p = 0.026)以及%NBF与IMSCL之间(DPBM: r = - 0.737；p = 0.015, DBBM: r =−0.573,p = 0.041),但不是RRH。在SW/IMSCL/RRH和%NBF之间，DPBM和DBBM的回归系数R2分别为0.435/0.543/0.258和0.377/0.328/0.053，表明猪移植材料对解剖结构的影响更大。多元回归分析证实了不同的异种移植物材料对% NBF的影响不同，对猪材料的影响显著（DPBM: R2 = 0.591 [59.1%] vs. DBBM: R2 = 0.314[31.4%]）。结论在LWSA中，SW和IMSCL等解剖结构显著影响新骨的形成，尽管不同的异种（猪和牛）骨矿物移植材料对新骨的影响不同。

期刊介绍： The goal of Clinical Implant Dentistry and Related Research is to advance the scientific and technical aspects relating to dental implants and related scientific subjects. Dissemination of new and evolving information related to dental implants and the related science is the primary goal of our journal. The range of topics covered by the journals will include but be not limited to: New scientific developments relating to bone Implant surfaces and their relationship to the surrounding tissues Computer aided implant designs Computer aided prosthetic designs Immediate implant loading Immediate implant placement Materials relating to bone induction and conduction New surgical methods relating to implant placement New materials and methods relating to implant restorations Methods for determining implant stability A primary focus of the journal is publication of evidenced based articles evaluating to new dental implants, techniques and multicenter studies evaluating these treatments. In addition basic science research relating to wound healing and osseointegration will be an important focus for the journal.
