目的
本研究的目的是测量种植体在骨结合期间的稳定性商(ISQ)值，并确定影响种植体稳定性的因素。
材料和方法
为了测量种植体的稳定性，对24例患者(女12例，男12例)进行了共振频率分析，共植入了定义的种植体，其中上颌10例，上颌12例，下颌18例，下颌24例。按Lekholm型和Zarb指数分型，其中II型52例，III型12例。在种植体植入当天及连续8周和10周时，用RFA直接测量种植体的稳定性。
结果
所有测量的种植体的平均ISQ为62.6。所有骨类型的平均稳定性测量在4周时最低(60.9)。性别被发现有显著意义(p<；0.05)；女性表现出比男性更高的种植体稳定性。关于牙弓内的位置，统计分析显示，前牙种植体的ISQ值高于后牙固定物(p<；0.05)。
PURPOSE
The objective of the present study was to measure the implant stability quotient (ISQ) values during the osseointegration period, and determine the factors that affect implant stability.
MATERIALS AND METHODS
To measure implant stability, resonance frequency analysis (RFA) was performed in 24 patients (12 women, 12 men) with a total 64 Defcon implants (10 anterior maxilla, 12 posterior maxilla, 18 anterior mandible, 24 posterior mandible). Bone type was classified according to the Lekholm and Zarb index (52 type II bone, 12 type III). RFA was used for direct measurement of implant stability on the day of implant placement and consecutively once a week for 8 weeks and at week 10.
RESULTS
The mean ISQ of all measured implants was 62.6. The lowest mean stability measurement was at 4 weeks for all bone types (60.9). Gender was found to be significant (p<0.05); women showed higher implant stability than men. In relation to location within the dental arch, statistical analysis showed higher ISQ values for anterior implants than posterior fixtures (p<0.05).
