“…Of all tested implants 63 were not osseointegrated and therefore could not be analyzed. All 40 studies 44,57‐95 used titanium implants, two studies further applied zirconia implants 70,76 . In 32 studies the implant design was screw‐shaped, seven studies used cylinder‐shaped implants, only one study used screw‐shaped and cylinder‐shaped implants 67 .…”

“…The literature search resulted in a total number of 4,174 titles of which 2,815 titles remained after automatic deduplication. Two thousand seven hundred and seventy five studies were excluded, the remaining 40 studies 44 , 57 , 58 , 59 , 60 , 61 , 62 , 63 , 64 , 65 , 66 , 67 , 68 , 69 , 70 , 71 , 72 , 73 , 74 , 75 , 76 , 77 , 78 , 79 , 80 , 81 , 82 , 83 , 84 , 85 , 86 , 87 , 88 , 89 , 90 , 91 , 92 , 93 , 94 , 95 were included in this systematic review. The main cause for exclusion was the application of different surface modifications, for example, the lack of an inorganic test surface (731).…”

A systematic review on the effect of inorganic surface coatings in large animal models and meta‐analysis on tricalcium phosphate and hydroxyapatite on periimplant bone formation

The aim of the present systematic review was to analyse studies using inorganic implant coatings and, in a meta-analysis, the effect of specifically tricalcium phosphate (TCP) and hydroxyapatite (HA) implant surface coatings on bone formation according to the PRISMA criteria. Inclusion criteria were the comparison to rough surfaced titanium implants in large animal studies at different time points of healing.Forty studies met the inclusion criteria for the systematic review. Fifteen of these analyzed the bone-to-implant contact (BIC) around the most investigated inorganic titanium implant coatings, namely TCP and HA, and were included in the meta-analysis. The results of the TCP group show after 14 days a BIC being 3.48% points lower compared with the reference surface. This difference in BIC decreases to 0.85% points after 21-28 days. After 42-84 days, the difference in BIC of 13.79% points is in favor of the TCP-coatings. However, the results are not statistically significant, in part due to the fact that the variability between the studies increased over time. The results of the HA group show a significant difference in mean BIC of 6.94% points after 14 days in favor of the reference surface. After 21-28 days and 42-84 days the difference in BIC is slightly in favor of the test group with 1.53% points and 1.57% points, respectively, lacking significance. In large animals, there does not seem to be much effect of TCP-coated or HA-coated implants over uncoated rough titanium implants in the short term.

BackgroundThis study aimed to compare the histomorphometric and histological bone response to laser-sintered implants followed by resorbable-blasting media (RBM) process relative to standard machined/RBM surface treated implants.Material and MethodsSix male sheep (n=6) received 2 Ti-6Al-4V implants (1 per surface) in each side of the mandible for 6 weeks in vivo. The histomorphometric parameters bone-implant contact (BIC) and bone area fraction occupancy (BAFO) were evaluated.ResultsOptical interferometry revealed higher Sa and Sq values for the laser-sintered/RBM surface in relation to standard/RBM implants. No significant differences in BIC were observed between the two groups (p>0.2), but significantly higher BAFO was observed for standard/RBM implants (p<0.01).ConclusionsThe present study demonstrated that both surfaces were biocompatible and osseoconductive, and the combination of laser sintering and RBM has no advantage over the standard machined implants with subsequent RBM. Key words:Dental implants, osseointegration, resorbable- blasting media, sheep, in vivo.

“…Since the discovery of osseointegration, different models of implants have been developed. Modifications occurred in both shape and surface, with the evolution of smooth machined to microscopically rough surfaces, which enhance bone healing around implants (4,17).…”

“…The contact between bone and endosseous implant is established and maintained after installation by the osseointegration process, in which the main element of the whole system is the implant itself, considering its macroscopic and microscopic characteristics (1)(2)(3). Morphological and chemical surface changes may alter the response of the bone tissue adjacent to the screw by inducing specific responses in the osteoblastic cells (4).…”

In Vitro Microstructural Analysis of Dental Implants Subjected to Insertion Torque and Pullout Test

The change in the implant microstructure during handling may reduce the potential of surface treatment on the osteoinduction and, therefore, on the osseointegration. The aim of this study was to evaluate by energy-dispersive X-ray spectroscopy (EDX) the effect of insertion torque and pullout test on the microstructure of dental implants with different shapes. Four shapes of implants (n=8) were selected: conical with surface treatment (COTS), cylindrical with surface treatment (CTS), cylindrical with double surface treatment (CTSD) and cylindrical with machined surface (CSU). Before and after performing the mechanical tests, the screw surfaces were subjected to analysis of chemical composition by EDX. The results obtained by the microstructural analysis showed presence of three main chemical elements: Ti, C and O. There was a significant change in the concentration of Ti and C. The implant with double surface treatment (CTSD) showed the greatest Ti reduction and the greatest C increase. It may be concluded that the mechanical manipulation may alter the implant surfaces as regards their microstructure. Therefore, surgical planning should take into consideration the choice of surface treatment because the characteristics of the implants may be modified as they are inserted and removed from the bone site.
