Abstract

The present study aimed to evaluate degree of functional and physiological integration of dental implant used for implant retained overdenture and comparing these adaptive change with conventional complete denture in edentulous participants. The psychophysical method evaluated active tactile sensibility (ATS) threshold of sensory receptors of oral cavity and neurophysiological method assessed neurological changes with help of functional magnetic resonance imaging (fMRI) during mastication in participants of both the groups. Mann-Whitney U test was done to compare ATS threshold and activity of sensory cortex in fMRI before and after implant installation in completely edentulous participants. Statistical result showed significant increase (P < 0.001) in activation of sensory cortex, motor cortex, prefrontal cortex, temporal lobe in participants after wearing implant retained overdenture compared with complete denture. For 200, 100, and 80 μm articulating papers non-significant change found between two test groups. The 40 and 12 μm articulating papers showed statistically significant change in ATS threshold (P < 0.05) between two test groups in 12-14 weeks. ATS threshold decreased more in participants with Implant retained overdenture prosthesis as compared with conventional complete denture prosthesis. Most of the activation was seen in prefrontal cortex and bilateral somato-sensory cortex with implant retained prosthesis compared with conventional complete denture prosthesis.

全口义齿佩戴者和种植固位覆盖义齿佩戴者的心理生理和神经生理活动比较：一项体内研究。

本研究旨在评估种植覆盖义齿的功能和生理整合程度，并将其与传统全口义齿的适应性变化进行比较。心理物理方法评估口腔感觉受体的主动触觉阈值（ATS），神经生理方法评估咀嚼过程中神经功能磁共振成像（fMRI）变化。采用Mann-Whitney U检验比较全牙无牙受试者在种植体安装前后的ATS阈值和fMRI感觉皮层活动。统计结果显示，与全口义齿相比，被试佩戴种植固位覆盖义齿后感觉皮层、运动皮层、前额叶皮层、颞叶的激活度显著增加（P < 0.001）。对于200、100和80 μm的铰接纸，两个测试组之间没有发现显著变化。在12-14周，40 μm和12 μm的论文ATS阈值在两组间差异有统计学意义（P < 0.05）。与传统的全口义齿相比，种植体保留覆盖义齿的ATS阈值下降更多。与传统全口义齿相比，种植体保留义齿的激活区主要集中在前额叶皮层和双侧躯体感觉皮层。

期刊介绍： MEDICAL IMPLANTS are being used in every organ of the human body. Ideally, medical implants must have biomechanical properties comparable to those of autogenous tissues without any adverse effects. In each anatomic site, studies of the long-term effects of medical implants must be undertaken to determine accurately the safety and performance of the implants. Today, implant surgery has become an interdisciplinary undertaking involving a number of skilled and gifted specialists. For example, successful cochlear implants will involve audiologists, audiological physicians, speech and language therapists, otolaryngologists, nurses, neuro-otologists, teachers of the deaf, hearing therapists, cochlear implant manufacturers, and others involved with hearing-impaired and deaf individuals.
