Abstract

Objective: The aim of the present pilot study is to investigate the effects of hydrophilicity and microtopography of titanium implant surfaces on initial supragingival plaque biofilm formation.

Materials and methods: Test specimens were manufactured from commercially pure grade 2 titanium according to one of the following procedures: polished (P), acid-etched (A), chemically modified (mod) A (modA), sand-blasted large grit and A (SLA), and modSLA. Intraoral splints were used to collect an in vivo supragingival plaque biofilm in each group at 12, 24, and 48 h. Stained plaque biofilm (PB) areas (%) were morphometrically assessed.

Results: All groups exhibited significant increases of mean PB areas over time (p < 0.001; respectively). Morphometrical analysis revealed the following mean PB areas: 12h: SLA = modSLA > P > A =modA (p < 0.001; respectively); 24h: SLA > modSLA = P > A = modA (p < 0.001; respectively); 48h: SLA = modSLA = P > A = modA (p < 0.001; respectively).

Conclusions: Within the limits of a pilot study, it could be concluded that hydrophilicity had no apparent effect, while microtopography had a highly uneven and unpredictable influence on supragingival plaque biofilm formation.

钛种植体表面的亲水性和微形貌对牙菌斑生物膜形成的影响。一项初步研究。

目的:探讨钛种植体表面的亲水性和微形貌对牙菌斑生物膜形成的影响。材料和方法:测试样品由商业纯2级钛根据以下程序之一制造:抛光(P)，酸蚀(A)，化学改性(mod) A (modA)，喷砂大砂砾和A (SLA)和modSLA。分别于12、24和48 h用口腔内夹板收集各组体内龈上菌斑生物膜。对染色菌斑生物膜(PB)面积(%)进行形态计量学评估。结果:随时间的推移，各组的平均PB面积均显著增加(p < 0.001;分别)。形态计量学分析显示:12h: SLA = modSLA > P > A =modA (P < 0.001);分别);24h: SLA > modSLA = P > A = modA (P < 0.001);分别);48h: SLA = modSLA = P > A = modA (P < 0.001;分别)。结论:在初步研究范围内，可以得出亲水性无明显影响，而微地形对龈上菌斑生物膜形成的影响高度不均匀且不可预测。
