Oral implants have helped clinicians to improve the quality of life for many patients. The material of choice for dental implants currently remains titanium type IV, whose mechanical and biological properties have been proven throughout the history of implantology. Yet, this material is not exempt from complications. For these reasons, ceramic alternatives to titanium have emerged. Thus, the purpose of this study is to evaluate peri-implant hard and soft tissue stability with the use of a one-piece ceramic implant (Straumann® PURE Ceramic Implant) during 1 year of follow-up.
One-piece all-ceramic zirconia (ZrO) implants were placed to replace single missing teeth in the esthetic zone. Six to 8 weeks after the procedure, the definitive prosthesis was fabricated. At the time of prosthesis, placement (T) photographs and periapical radiographs were taken, and the following clinical parameters were recorded: probing depth (PD), plaque index (PI), bleeding on probing (BOP), suppuration on probing (SOP), distance from gingival margin to incisal edge (GM-IE), and Jemt papilla index (JPI). Follow-up appointments were scheduled at 4 (T), 8 (T), and 12 (T) months, when the same parameters were recorded. In addition, plaque control was reinforced and prophylaxis was carried out. In this last appointment, a final periapical radiograph was taken to assess marginal bone loss.
A total of 32 zirconia implants were placed in 28 patients (16 women and 12 men, aged between 34 and 67 years). The survival and success rate were 96.9%. The increase in probing depth from baseline to 12 months was 0.78 mm. Assessments of plaque index and bleeding on probing showed a slight increase throughout the study.
The results obtained with the Straumann® PURE Ceramic implants show them to exhibit very good clinical behavior. The survival rate of the implants of our pilot study was 96.9%. For these reasons, we can say that zirconia implants could be an alternative to titanium implants in the esthetic zone.
口腔种植体帮助临床医生提高了许多患者的生活质量。目前，牙科种植体的首选材料仍然是钛 IV 型，其机械和生物学性能在种植学的历史中已经得到验证。然而，这种材料并非没有并发症。出于这些原因，已经出现了替代钛的陶瓷材料。因此，本研究旨在评估使用一体式陶瓷种植体（Straumann®PURE 陶瓷种植体）在 1 年随访期间对种植体周围软硬组织的稳定性。
一体式全陶瓷氧化锆（ZrO）种植体被植入以替代美观区单个缺失的牙齿。在手术后 6 至 8 周，制作最终修复体。在修复体放置时（T）拍摄照片和根尖片，并记录以下临床参数：探诊深度（PD）、菌斑指数（PI）、探诊出血（BOP）、探诊溢脓（SOP）、龈缘到切缘的距离（GM-IE）和 Jemt 乳头指数（JPI）。在 4（T）、8（T）和 12（T）个月时安排随访预约，记录相同的参数。此外，强化了菌斑控制和进行了洁治。在最后一次预约时，拍摄最终根尖片以评估边缘骨丧失。
共在 28 名患者（16 名女性和 12 名男性，年龄在 34 至 67 岁之间）中植入了 32 个氧化锆种植体。种植体的存活率和成功率为 96.9%。从基线到 12 个月时，探诊深度增加了 0.78 毫米。整个研究过程中，菌斑指数和探诊出血的评估显示略有增加。
Straumann®PURE 陶瓷种植体的结果表明它们具有非常好的临床行为。我们的试点研究中种植体的存活率为 96.9%。基于这些原因，我们可以说氧化锆种植体在美观区可能是钛种植体的替代品。
