This study aimed to evaluate biphasic calcium phosphate coating (BCPC) on the secondary stability of dental implants compared to sand-blasted and acid-etched (SLA) implants.
This is a split-mouth study. Thirty subjects (20 males and ten females) underwent a dental implant procedure to replace mandibular first or second molars bilaterally. The subjects were randomly assigned to BCPC or SLA groups. The resonance frequency analysis measurements were performed two, four, six, and eight weeks after the implant placement.
Sixty implants were placed in the two groups (30 implants per group). The mean ISQ was 52.26 ± 3.73 in group 1 and 50.21 ± 2.59 in group 2 on day 14 after the implant insertion, 63.20 ± 2.76 in group 1 and 58.80 ± 2.14 in group 2 on day 28, 72.30 ± 3.15 in group 1 and 64.53 ± 3.19 in group 2 on day 42, and 78.70 ± 1.56 in group 1 and 71.63 ± 3.22 in group 2 on day 56. The data analysis demonstrated significant differences between the two groups in terms of the mean ISQ at various evaluation times.
Regarding ISQ measurements, the secondary stability in BCPC implants may be higher compared to SLA implants in two months after implant insertion.
本研究旨在评估双相磷酸钙涂层（BCPC）牙种植体与喷砂酸蚀（SLA）种植体相比的二级稳定性。
这是一项双侧对照研究。30名受试者（20名男性和10名女性）接受了牙种植手术，双侧替换下颌第一或第二磨牙。受试者被随机分配到BCPC组或SLA组。在种植体植入后2周、4周、6周和8周进行共振频率分析测量。
两组共植入60颗种植体（每组30颗）。种植体植入后第14天，第1组的平均植入稳定性商数（ISQ）为52.26±3.73，第2组为50.21±2.59；第28天，第1组为63.20±2.76，第2组为58.80±2.14；第42天，第1组为72.30±3.15，第2组为64.53±3.19；第56天，第1组为78.70±1.56，第2组为71.63±3.22。数据分析表明，两组在不同评估时间的平均ISQ方面存在显著差异。
关于ISQ测量，在种植体植入后两个月内，BCPC种植体的二级稳定性可能高于SLA种植体。
