Abstract

OBJECTIVES

To investigate how different types of dental prosthesis perform in patients with head and neck tumors.

MATERIALS AND METHODS

In this retrospective clinical cohort study, the impact of different patient-related factors was analyzed as influencing factors on the survival probability of dental prosthesis using Kaplan-Meier estimate. For analysis, the dental prosthesis was divided into groups: group 1 (fixed dental prosthesis), group 2 (removable dental prosthesis), group 3 (implant-supported dental prosthesis), and group 4 (prostheses anchored using wrought wire clasps and obturators). The incidental aftercare measures were also evaluated.

RESULTS

Two hundred seventy-nine restorations were observed (mean observation: 2.7 ± 3.0 years, max.14.8 years) out of which 49 (17.6%) had to be replaced during the observation. After 5 years, 100% of group 1 restorations, 79.9% of group 2 restorations, 91.4% of group 3 restorations, and 30% of group 4 restorations were still functional. Four hundred eighty-eight dental implants were observed, of which 77 (15.8%) failed.

CONCLUSIONS

Groups 1, 2, and 3 restorations showed good survival times after 5 years in function, whereas group 4 presented the worst survival times. Group 2 restorations showed the highest amount of necessary aftercare measures.

CLINICAL RELEVANCE

The current investigation shows that groups 1, 2, and 3 restorations should be preferred in the prosthetic treatment planning of patients with head and neck tumors. A treatment with group 4 restorations should only be considered if no other prosthetic treatment is possible or as temporary treatment.

摘要

目的

研究不同类型的牙修复体在头颈部肿瘤患者中的应用效果。

材料与方法

本回顾性临床队列研究分析了不同患者相关因素对牙修复体生存率的影响，采用 Kaplan-Meier 估计分析。将牙修复体分为 4 组：组 1（固定义齿）、组 2（可摘义齿）、组 3（种植体支持义齿）和组 4（用锻造金属丝卡环和闭塞器固位的义齿）。还评估了偶然的后续护理措施。

结果

观察到 279 个修复体（平均观察时间：2.7±3.0 年，最长 14.8 年），其中 49 个（17.6%）在观察期间需要更换。5 年后，组 1 修复体的 100%、组 2 修复体的 79.9%、组 3 修复体的 91.4%和组 4 修复体的 30%仍能正常使用。观察到 488 个牙种植体，其中 77 个（15.8%）失败。

结论

组 1、2 和 3 修复体在 5 年后功能上具有良好的存活率，而组 4 则表现出最差的存活率。组 2 修复体需要进行最多的后续护理措施。

临床相关性

目前的研究表明，在头颈部肿瘤患者的修复治疗计划中，应优先考虑组 1、2 和 3 修复体。只有在没有其他修复治疗可能或作为临时治疗的情况下，才应考虑使用组 4 修复体。
