Abstract

Purpose: To investigate the medium-term survival of Dalbo-Rotex retention elements, identify potential risk factors for complication or loss, and consider economic factors.

Materials and methods: Patients treated with Dalbo-Rotex retention elements in a university setting were retrospectively identified and examined. Clinical data comprised assessments of the dental, periodontal, endodontic, and prosthetic situation, including radiographic analysis. Patient satisfaction was quantified with visual analog scale questionnaires. Five-year Kaplan-Meier plots for relative survival and success rates were calculated.

Results: The 45 included patients had a total of 76 Dalbo-Rotex retention elements. Of these, 12 Dalbo-Rotex elements failed and complications occurred in 42.1% of elements, equating to a survival rate of 84.2% and a success rate of 47.4% after a mean observation period of 49.2 ± 52.4 months (range: 6 to 219 months). The 5-year cumulative survival and success rates were 62.4% (95% CI: 44.0% to 88.4%) and 35.6% (95% CI: 23.8% to 53.2%), respectively. Patients' self-assessment of prosthesis retention was rated at 82 (IQR 40 to 92.2) with low pain perception at 4.5 (IQR 0 to 30). Probing pocket depth levels were significantly reduced in patients adhering to a regular recall interval compared with those with longer intervals.

Conclusions: Chairside Dalbo-Rotex retention elements are a straightforward chairside method for prosthesis retention that achieve good survival over medium-term follow-ups with high patient satisfaction. This technique is therefore a viable alternative to cast post copings and can be particularly valuable for patients with limited financial resources.

Dalbo-Rotex Retention Elements 的中期观察:回顾性队列研究
目的:调查Dalbo-Rotex留置元件的中期存活率,确定并发症或损失的潜在风险因素,并考虑经济因素:对在一所大学接受过Dalbo-Rotex固位体治疗的患者进行回顾性鉴定和检查。临床数据包括对牙齿、牙周、牙髓和修复情况的评估,包括放射学分析。患者满意度通过视觉模拟量表问卷进行量化。计算了五年相对存活率和成功率的卡普兰-梅耶图:结果:45名患者共使用了76个Dalbo-Rotex固位体。平均观察期为 49.2 个月(标准差 52.4,范围为 6-219 个月),其中有 12 个 Dalbo-Rotex 元件失败,42.1%的元件出现并发症,存活率为 84.2%,成功率为 47.4%。5年累计存活率和成功率分别为62.4%(95% CI 44.0-88.4%)和35.6%(95% CI 23.8-53.2%)。患者对义齿固位的自我评估为 82(IQR 40-92.2),低疼痛感为 4.5(IQR 0-30)。与间隔时间较长的患者相比,坚持定期复查的患者探查袋深度水平明显降低:椅旁Dalbo-Rotex固位元件是一种简单的椅旁义齿固位方法,在中期随访中的存活率很高,患者满意度也很高。因此,这种技术是石膏后牙托的一种可行替代方法,对于经济条件有限的患者尤为重要。
