摘要
背景:种植体治疗成功的一个基本前提是有足够数量和质量的骨。目的:本研究的目的是通过在上颌窦底故意穿孔放置种植体时,在不同深度放置种植体周围的骨形成及其对种植体成活率的影响。设置和设计:在种植过程中,57例患者通过上颌窦底故意穿孔,将86颗不同尺寸的种植体放置在上颌前磨牙和磨牙区域。对象与方法:根据入颌窦深度(经[IS]隔室区域)分为G1、G2、G3三组(IS-G1-1 mm;G2-2 mm;G3-3毫米)。评估以下参数-种植体放置6个月后的扭矩、骨密度和骨填充。统计分析方法:重复测量资料组间比较采用方差分析重复测量检验。扭矩与骨填充两项参数的相关性采用Karl Pearson相关检验。结果:三组间扭矩、骨填充、骨密度从基线至6个月无显著差异。转矩与骨填充的相关性R = 0.198, P = 0.293,差异无统计学意义。结论:研究结束时的失败率和并发症均为最小。种植体的成活率不受扭矩和种植体进入上颌窦的深度的影响。
Outcomes of intentional perforation of the maxillary sinus floor during implant placement: A single-center, prospective study in 57 subjects
Context: An essential precondition for successful implant therapy is the presence of an adequate quantity and quality of bone. Aims: The purpose of this study was to radiographically evaluate the bone formation around the dental implants which were placed at different depths into the maxillary sinus by intentional perforation of maxillary sinus floor during implant placement and its effect on implant survival rate. Settings and Design: A total of 86 implants of varying dimensions were placed in maxillary premolar and molar region by intentional perforation of the maxillary sinus floor during implant placement in 57 patients. Subjects and Methods: They were divided into three groups G1, G2, and G3 based on the depth of penetration into the maxillary sinus (region by [IS] compartment) (IS-G1-1 mm; G2-2 mm; G3-3 mm). The following parameters were evaluated-torque, bone density, and bone fill after 6 months of implant placement. Statistical Analysis Used: The comparison among groups for repeated measures data was made by ANOVA repeated measures test. The correlation between two parameters, i.e., torque and bone fill was done by Karl Pearson's correlation test Results: No significant differences were observed among the three groups for torque, bone fill, and bone density from baseline to 6 months. The correlation between torque and bone fill revealed R = 0.198, P = 0.293 which was statistically insignificant Conclusions: There were minimal failure rates and complications observed at the end of the study period. The survival rate of implants was not influenced either by torque or by the depth of penetration of implant into the maxillary sinus.
