Replacing missing teeth with dental implants has become the best treatment option; therefore, clinicians need to understand the predictability of the treatment. Surface treatment of implants is one of the methods to improve osseointegration, thus improving the quality of treatment. Increasing esthetic awareness among patients has led to the popularity of immediate provisionalization of dental implants. This study investigated the effect of surface treatment on implant stability when loaded with immediate non-functional temporary prostheses and compared the superiority of one surface treatment over the other in terms of osseointegration by evaluating implant stability quotient (ISQ).
Twenty implants with different surface treatments were placed, i.e., resorbable blast media (RBM) surface and alumina blasted/acid-etched (AB/AE) surfaces. All the implants were non-functionally loaded, and ISQ was measured immediately after implant placement and 6 and 12 weeks after non-functional loading. Crestal bone levels, mPI, mSBI, and peri-implant probing depths were compared for both groups at 1, 3, and 6 months.
At 12 weeks, all the implants showed desirable ISQ, indicating successful osseointegration. The increase in ISQ at 12 weeks was significantly higher for RBM implants compared to baseline, indicating a more predictable course of osseointegration. Crestal bone levels recorded at 1, 3, and 6 months did not significantly differ between the groups. All other parameters showed comparable values for both groups at all intervals.
Replacing missing teeth with dental implants with immediate non-functional restorations is a predictable treatment option.
用牙种植体替代缺失牙已成为最佳治疗选择；因此，临床医生需要了解该治疗的可预测性。种植体表面处理是改善骨结合的方法之一，从而提高治疗质量。患者审美意识的提高导致了牙种植体即刻临时修复的普及。本研究调查了即刻非功能性临时修复体加载时表面处理对种植体稳定性的影响，并通过评估种植体稳定性商数（ISQ）比较了一种表面处理相对于另一种表面处理在骨结合方面的优势。
植入20颗具有不同表面处理的种植体，即可吸收喷砂介质（RBM）表面和氧化铝喷砂/酸蚀（AB/AE）表面。所有种植体均进行非功能性加载，并在种植体植入后即刻以及非功能性加载后6周和12周测量ISQ。在1、3和6个月时比较两组的嵴顶骨水平、改良菌斑指数（mPI）、改良龈沟出血指数（mSBI）和种植体周围探诊深度。
在12周时，所有种植体均显示出理想的ISQ，表明骨结合成功。与基线相比，RBM种植体在12周时ISQ的增加显著更高，表明骨结合过程更可预测。两组在1、3和6个月时记录的嵴顶骨水平无显著差异。所有其他参数在所有时间间隔内两组均显示出可比的值。
用即刻非功能性修复体的牙种植体替代缺失牙是一种可预测的治疗选择。
