However, this technique requires sufficient implant stability before and during the rehabilitation period to mitigate the risk of implant breakage and loosening. Hence, reliable assessment methods for the osseointegration process are essential to ensure initial and long\u2013term implant stability. This paper researches the feasibility of a vibration analysis technique for the osseointegration (OI) process by investigating the change in the dynamic response of the residual femur with a novel implant design during a simulated OI process. The paper also proposes a concept of an energy index (the E\u2013index), which is formulated based on the normalized magnitude. To illustrate the potential of the E\u2013index, this paper reports on changes in the vibrational behaviors of a 133 mm long amputated artificial femur model and implant system, with epoxy adhesives applied at the interface to simulate the OI process. The results show a significant variation in the magnitude of the colormap against curing time. The study also shows that the E\u2013index was sensitive to the interface stiffness change, especially during the early curing process. These findings highlight the feasibility of using the vibration analysis technique and the E\u2013index to quantitatively monitor the osseointegration process for future improvement on the efficiency of human health monitoring and patient rehabilitation.<\/jats:p>","DOI":"10.3390\/s22041685","type":"journal-article","created":{"date-parts":[[2022,2,21]],"date-time":"2022-02-21T20:48:41Z","timestamp":1645476521000},"page":"1685","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":4,"title":["Experimental Investigation of Vibration Analysis on Implant Stability for a Novel Implant Design"],"prefix":"10.3390","volume":"22","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-6760-2204","authenticated-orcid":false,"given":"Shouxun","family":"Lu","sequence":"first","affiliation":[{"name":"Department of Mechanical & Aerospace Engineering, Monash University, Melbourne, VIC 3800, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0991-4293","authenticated-orcid":false,"given":"Benjamin Steven","family":"Vien","sequence":"additional","affiliation":[{"name":"Department of Mechanical & Aerospace Engineering, Monash University, Melbourne, VIC 3800, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Matthias","family":"Russ","sequence":"additional","affiliation":[{"name":"The Alfred Hospital, Melbourne, VIC 3004, Australia"},{"name":"National Trauma Research Institute, Melbourne, VIC 3004, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mark","family":"Fitzgerald","sequence":"additional","affiliation":[{"name":"The Alfred Hospital, Melbourne, VIC 3004, Australia"},{"name":"National Trauma Research Institute, Melbourne, VIC 3004, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4359-2814","authenticated-orcid":false,"given":"Wing Kong","family":"Chiu","sequence":"additional","affiliation":[{"name":"Department of Mechanical & Aerospace Engineering, Monash University, Melbourne, VIC 3800, Australia"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2022,2,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"1377","DOI":"10.1177\/1475921718782399","article-title":"IWSHM 2017: Application of guided wave methods to quantitatively assess healing in osseointegrated prostheses","volume":"17","author":"Wang","year":"2018","journal-title":"Struct.
