The aim of this study is to assess the effectiveness of using non-titanium abutments for better establishment of peri-implant biological width and to assess the stability of the soft tissue. Forty-eight tapered dental titanium implants with internal connection of 3.5mm in diameter and 10mm length were implanted in post extraction alveoli of 6 dogs. Twenty-four abutments made in a reinforced polyetheretherketone (PEEK) formed the test group, and 24 titanium abutments, the control group. The groups were randomized. Histological, histomorphometric, ISQ and radiological analyses were performed. Greatest differences (control group vs. test group) were found at PM-Lc (Mucosa to lingual bone contact) (2.91±0.03 vs. 3.71±0.18), and to PM Lingual-IS (2.65±0.43 vs. 3.57±0.38). Reinforced PEEK constitutes an effective alternative to conventional titanium abutments, given its high rate of biocompatibility, preservation of bone height and soft tissue stability.
本研究的目的是评估使用非钛基台对更好地建立种植体周围生物学宽度的有效性，并评估软组织的稳定性。将48颗直径3.5mm、长度10mm且具有内部连接的锥形牙科钛种植体植入6只狗的拔牙后牙槽窝中。由增强聚醚醚酮（PEEK）制成的24个基台组成试验组，24个钛基台组成对照组。两组随机分组。进行了组织学、组织形态计量学、种植体稳定性商数（ISQ）和放射学分析。在PM-Lc（黏膜至舌侧骨接触）（2.91±0.03对3.71±0.18）以及PM舌侧-IS（2.65±0.43对3.57±0.38）方面发现了最大差异。鉴于增强PEEK具有高生物相容性、能保持骨高度和软组织稳定性，它是传统钛基台的一种有效替代品。
