Interface Damage in Titanium Dental Implant Due to Tribocorrosion: The Role of Mastication Frequencies

Bio-Tribocorrosion of Titanium Dental Implants and Its Toxicological Implications: A Scoping Review

“…ere were 26 in-vitro studies [8-27, 29, 30, 32, 33, 35, 39], 3 ex-vivo studies [5,28,38], 3 observational in-vivo studies [31,34,36], 1 case-control study [37], and 1 case report [40]. Eighteen studies reported the factors responsible for biotribocorrosion [8][9][10][11][12][13][14][15][16][17][18][19][20][21][22][23][24][25], while 16 reported the toxic effects of the released metal ions [5,[26][27][28][29][30][31][32][33][34][35][36][37][38][39][40]. e review results are summarized as follows:…”

“…e tribological behaviour of dental implants was assessed using tribometer systems with the help of a pin/ball on a disc [8,13,18,20] or a pin/ball on a plate [9,11,12,16,19,22,24,25] (Figure 2(a)). Typically, the studies applied loads as low as 20 mN [19] to as high as 20 N [8].…”

“…Typically, the studies applied loads as low as 20 mN [19] to as high as 20 N [8]. Loads of 1 N [9,25], 2 N [10,22,24], 5 N [13], and 8 N [18,20] were commonly applied. ese forces corresponded to a mean contact pressure ranging from 0.91 MPa [20] to 190 MPa [16] and initial contact pressure of 320 [8,9,25] to 998.7 MPa [13,22,24].…”

“…e tests were performed at a frequency of 1 Hz [8-10, 16, 20-22, 24], 2 Hz [18][19][20]25], and 4 Hz [20] during 1000 [16], 1300 [19], 2000 [8], 5000 [10], or 25000 cycles [18]. e strokes ranged from 1 [19,20] to 2 mm [9,18,25]. Tribocorrosion due to fretting [10,20] and sliding [8,9,13,16,18,19,22,24,25] was evaluated.…”

A review of the bio-tribology of medical devices

“…However, there are still many failed clinical cases. The possible causes are interface fretting and corrosion [96,97]. Although they are difficult to detect, they directly affect the bone ingrowth at the initial stage of implantation and the long-term lifetime of the dental implant [98].…”
