The satisfaction of patients with dentures on implants has different points of view that become fundamental aspects for the development of research on the quality of life of these patients, the eventual biomechanical complications to which these prostheses and implants can be subjected, and design considerations for cantilever extensions.
The objective of research was to assess the implants and prosthesis survival rates, biomechanical complications relative to the length of the distal extensions (cantilevers), and the satisfaction of the patients with a fixed implant-supported full-arch fiber-reinforced composites prosthesis.
A retrospective clinical and radiographic cohort study was developed. Clinical records of a selected cohort were analyzed according to inclusion and exclusion criteria. Data on a patient who underwent to fixed implant-supported full-arch fiber-reinforced composites prosthesis at least of five years of function were collected. Data analysis was performed using Kaplan-Meier curves and Fisher's Exact Test. P values less than 0.05 were considered statistically significant.
After insertion, 1 of 29 prostheses failed, the overall prosthetic survival rate observed at 5 years was 96.5%. Of the 120 implants placed in 28 patients, only 4 patients experienced loss of an implant during the 5 years of observation; the implant survival rate throughout the observation period was 86.2%. Distal extension seems to negatively affect the prognosis of implant-supported rehabilitation. Regarding the level of satisfaction of the patient with the prosthesis, none reported being uncomfortable or dissatisfied neither with their appearance nor with the taste of food throughout the studied period.
No relevant associations were found between the variables involved. The study found the improvement in quality of life following the installation of fixed rehabilitation on the patients. Once the potential benefits of patients are obtained, controlled clinical trials are encouraged.
对于种植义齿患者的满意度存在不同观点，这些观点对于研究此类患者的生活质量、这些假体和种植体可能出现的生物力学并发症以及悬臂延伸的设计考量而言，成为了基本方面。
本研究的目的是评估种植体和假体的生存率、与远端延伸（悬臂）长度相关的生物力学并发症，以及患者对固定种植体支持的全牙弓纤维增强复合材料假体的满意度。
开展了一项回顾性临床和影像学队列研究。根据纳入和排除标准对选定队列的临床记录进行分析。收集了至少使用固定种植体支持的全牙弓纤维增强复合材料假体功能达五年的患者的数据。使用Kaplan-Meier曲线和Fisher精确检验进行数据分析。P值小于0.05被认为具有统计学意义。
植入后，29个假体中有1个失败，5年时观察到的总体假体生存率为96.5%。在28名患者中植入的120颗种植体，在5年观察期内只有4名患者出现种植体脱落；整个观察期内种植体生存率为86.2%。远端延伸似乎对种植体支持的修复预后有负面影响。关于患者对假体的满意度，在整个研究期间，没有人报告在外观或食物味道方面感到不适或不满意。
未发现所涉及变量之间存在相关关联。该研究发现患者安装固定修复体后生活质量有所改善。一旦获得患者的潜在益处，鼓励开展对照临床试验。
