OBJECTIVES
The objective is to compare demineralized freeze-dried bone and modified hydroxyapatite granules in patients requiring immediate dental implants.
MATERIALS AND METHODS
Forty patients for immediate dental implants were divided into Group I (demineralized freeze-dried bone allograft) and Group II (modified hydroxyapatite) based on the type of graft used. Success of graft was evaluated based on modified plaque index, gingival index, and Periotest at 3, 6, and 12 months follow up.
RESULTS
The mean modified plaque index, gingival index, peri-implant sulcular depth, and Periotest were recorded at baseline, 3, 6, and 12 months at implant site and full mouth in both groups found to be nonsignificant ( > 0.05).
CONCLUSION
Both demineralized freeze-dried bone allograft and modified hydroxyapatite grafts were equally efficient in immediate dental implant placement sites.
目的
目的是比较脱矿冻干骨和改性羟基磷灰石颗粒在需要即刻种植牙的患者中的应用。
材料与方法
40例需要即刻种植牙的患者根据所使用的移植材料类型分为I组（脱矿冻干同种异体骨）和II组（改性羟基磷灰石）。在3、6和12个月的随访中，根据改良菌斑指数、牙龈指数和牙周测试评估移植材料的成功率。
结果
在基线、3、6和12个月时记录两组患者种植部位和全口的平均改良菌斑指数、牙龈指数、种植体周围龈沟深度和牙周测试结果，发现差异无统计学意义（>0.05）。
结论
脱矿冻干同种异体骨移植和改性羟基磷灰石移植在即刻种植牙植入部位的效果相同。
