■钛牙种植体,传统上用于更换牙齿,面临某些生物学和美学限制。最近,氧化锆已成为一种值得注意的替代品,因其美学和生物相容性而受到重视。这项研究评估了两件式氧化锆牙科植入物的疗效,特别是它们对炎性细胞因子的影响及其一年以上的存活率。
■这项研究是一个单中心,前瞻性试验,包括18岁及以上的成年人。2021-2022年,在8名患者中放置了9个两件式组织级氧化锆植入物。经过三个月的骨整合阶段,牙冠被胶结。一年多,我们评估了菌斑和牙龈指数,口袋深度,和组织的颜色和质地。心尖周围X光片测量骨水平,和IL-1β在种植体周围液(PICF)使用ELISA定量。
■8名受试者(31-63岁)参加。一个植入物六个月后失败了,一年生存率为88.8%。菌斑和牙龈指数上升,但种植体周围软组织颜色和质地保持稳定。12个月时,与基线相比,平均骨丢失最小且不显著.IL-1β水平与对侧牙齿相似,IL-1β之间没有相关性,口袋深度,在探测时出血。
■两件式氧化锆植入物成为一种可行的牙齿替代选择,一年生存率为88.8%。他们维持稳定的软组织和骨骼水平,表明它们作为有效牙科修复剂的潜力。
UNASSIGNED: Titanium dental implants, traditionally used for tooth replacement, face certain biological and aesthetic limitations. Recently, zirconia has become a notable alternative, valued for its aesthetics and biocompatibility. This study evaluated the efficacy of two-piece zirconia dental implants, particularly their impact on inflammatory cytokines and their survival rate over one year.
UNASSIGNED: This study was a single-center, prospective trial and included adults aged 18 and above. 2021-2022, nine two-piece tissue-level zirconia implants were placed in eight patients. Following a three-month osseointegration phase, crowns were cemented. Over a year, we assessed Plaque and Gingival indices, Pocket Depth, and tissue color and texture. Peri-apical radiographs measured bone levels, and IL-1β in peri-implant crevicular fluid (PICF) was quantified using ELISA.
UNASSIGNED: Eight subjects (ages 31-63) participated. One implant failed after six months, resulting in a one-year survival rate of 88.8%. Plaque and Gingival indices rose, but peri-implant soft tissue remained stable in color and texture. At 12 months, average bone loss was minimal and insignificant compared to the baseline. IL-1β levels were similar to those at contralateral teeth, with no correlation between IL-1β, Pocket Depth, and Bleeding on Probing.
UNASSIGNED: Two-piece zirconia implants emerged as a viable tooth replacement option, with an 88.8% one-year survival rate. They maintained stable soft tissue and bone levels, indicating their potential as effective dental restoratives.
