This study compared the effects of three different methods of preparing bone implant sockets (drilling, osteotomes, and piezoelectric device) on osseointegration using resonance frequency analysis (RFA).
An experimental prospective study was designed.
Ten adult beagle dogs were studied. After 5 weeks, 23 out of 28 initially placed implants in the iliac crest were evaluated, comparing these three different procedures of bone implant socket. Student's t-test (paired, two-tailed) was used to reveal differences among the three groups at each time point (SPSS 16.0, IL, USA).
After a 5-week healing period, the implants placed in sockets that were made using an osteotome or piezoelectric device were slightly more stable than those made by drilling. Reduced mechanical and heat injury to the bone is beneficial for maintaining and improving stability during the critical early healing period.
Using RFA, there was evidence of a slight increase in implant stability in the iliac crest after 5 weeks of healing when the implant socket was made using a piezoelectric device or expansion procedure as compare with the drilling method. Key words:Bone implant sockets, drilling, osteotomes, piezoelectric, resonance frequency analysis, stability.
本研究使用共振频率分析(RFA)比较三种不同的骨种植窝制备方法(钻孔、骨凿和压电装置)对骨整合的影响。
设计了一项实验性前瞻性研究。
对10只成年比格犬进行研究。5周后,对最初植入髂嵴的28枚种植体中的23枚进行评估,比较这三种不同的骨种植窝制备方法。采用学生t检验(配对,双侧)来揭示三个组在每个时间点的差异(SPSS 16.0,美国伊利诺伊州)。
经过5周的愈合期后,使用骨凿或压电装置制备种植窝的种植体比钻孔制备的种植体稍稳定。减少对骨的机械和热损伤有利于在关键的早期愈合期维持和提高稳定性。
使用RFA,有证据表明,与钻孔法相比,使用压电装置或扩孔法制备种植窝时,愈合5周后髂嵴处种植体的稳定性略有增加。关键词:骨种植窝、钻孔、骨凿、压电、共振频率分析、稳定性
