摘要

背景:本研究比较了钛和氧化锆种植体结扎引起的种植体周围缺损进展和对再生手术干预的反应:本研究比较了钛和氧化锆种植体结扎引起的种植体周围缺损进展以及对再生手术干预的反应:方法:在 6 只混种猎狐犬中植入 8 个组织水平的骨内种植体,每个半颌交替植入 2 个氧化锆和 2 个钛种植体。在龈下放置棉花结扎带 16 周,然后自发进行 8 周。每 2 周拍摄一次标准化 X 光片,以评估骨质流失率。利用喷水去污、釉质基质衍生物和当地采集的自体骨进行再生手术。愈合16周后,对最终的放射骨水平、探查深度、后退和临床附着水平进行评估:结果:所有 48 个种植体均成功整合。钛和氧化锆种植体最终的平均结扎后影像学缺损分别为 2.88 毫米和 3.05 毫米。不同材料的骨质流失率无明显差异(P = 0.09)。再生手术后,钛和氧化锆材料的放射骨增量总平均值分别为 1.41 毫米和 1.20 毫米。钛和氧化锆的缺损填充率分别为 51.56% 和 37.98%(p = 0.03)。牺牲时的临床参数,包括牙周袋深度(p = 0.81)、牙周退缩(p = 0.98)或临床附着水平(p = 0.51),组间差异极小:结论:钛和氧化锆种植体在种植体周围缺损发展率方面没有明显差异。两种材料在再生手术后都获得了明显的放射性骨量,但钛种植体的缺损填充率明显更高。两组的最终临床参数相似。

Peri-implantitis induction and resolution around zirconia versus titanium implants.

Background: This study compared titanium and zirconia implant ligature-induced peri-implant defect progression and response to regenerative surgical intervention.

Methods: Eight tissue-level endosseous implants were placed in 6 mixed-breed foxhounds, with 2 zirconia and 2 titanium alternating in each hemimandible. Cotton ligatures were placed subgingivally for 16 weeks followed by 8 weeks of spontaneous progression. Standardized radiographs were captured every 2 weeks to evaluate the rate of bone loss. Regenerative surgery was performed utilizing water-jet decontamination, enamel matrix derivative, and locally harvested autogenous bone. After 16 weeks of healing, final radiographic bone levels as well as probing depths, recession, and clinical attachment levels were assessed.

Results: All 48 implants integrated successfully. The final average post-ligature radiographic defects were 2.88 and 3.05 mm for titanium and zirconia implants, respectively. There was no significant difference between materials in the rate of radiographic bone loss (p = 0.09). Following regenerative surgery, the total average amount of radiographic bone gain was 1.41 and 1.20 mm for titanium and zirconia, respectively. The percentage of defect fill was 51.56% and 37.98% (p = 0.03) for titanium and zirconia, respectively. Inter-group differences were minimal for clinical parameters at the time of sacrifice including periodontal pocket depths (p = 0.81), recession (p = 0.98), or clinical attachment levels (p = 0.51).

Conclusions: No significant difference was found in the rate of peri-implant defect development between titanium and zirconia implants. Both materials gained significant radiographic bone following regenerative surgery with significantly greater defect percentage fill in titanium implants. The final clinical parameters were similar in both groups.
