“…The main finding of the presented investigation is the feasibility of the SEM‐EDS technique to preserve biological probes despite the exposure towards radiation. The presented results relative to the effect of insertion of implants with different surface structures correlated with previous published studies, where it was observed that insertion of rough implants led to a greater extent of titanium wear than smooth surfaces (Goodman et al 1996; Budd et al 1999; Scarano et al 2003). In contrast to these studies, Wennerberg et al (2004) were unable to verify a difference in ionic leakage after insertion of implants with different roughnesses in the tibiae of rabbits.…”

“…Whereas Woodman et al (1984) failed to find any pathology associated with titanium leakage in a long‐term animal study, particulate debris has been shown by others to promote fibroblast proliferation, being an important factor in the creation of the fibrous membrane surrounding the implant surface (Garcia‐Alonso et al 2003). Moreover, the phagocytosis of the particles by different cells has been demonstrated to be indirectly responsible for peri‐implant osteolysis (Bi et al 2001; Scarano et al 2003). As ‘aseptic’ implant failure does occur and as the underlying reasons for some implant failures are multi‐causal, the influence of single parameters are not entirely known.…”

The effect of unintended titanium release around oral implants remains a biological concern. The current study was undertaken to evaluate a new detection system of element mapping in biological probes. A new scanning electron microscopy-energy dispersive spectroscopy detection method was used to map the features of titanium contamination in peri-implant bone around implants with different surface structures. The amount of titanium wear was highest adjacent to titanium-plasma-sprayed surfaces, followed by sandblastered large grid acid-etched and smooth surfaces. A high sensitivity of titanium detection over large areas of bone tissue was observed. A high spatial resolution of titanium wear particles (20 nm) could be reached and correlated to the ultrastructural morphological features of peri-implant tissue. Cells adjacent to titanium wear revealed no signs of morphological alterations on a nanoscale level at early periods of implant/bone interaction. The new technique may serve as a fast and effective tool to evaluate titanium release effects in biological probes.

“…Weiss et al14 conducted experiments using 7 implant systems and opening torque was measured after 30 times and 200 times of repeated tightening and loosening of upper part, and reported that as the repetition increases, opening torque decreases. Also, they proposed that the decrease of the frictional coefficient caused by abrasion between abutment screw and its component due to repeated tightening and loosening of upper part, was the cause of decreased open torque.…”

“…However, with the recent development of TiN coating technique, some dentists began to apply the TiN coating to the implant system. Scarano et al14,15 reported that TiN coating had good biocompatibility and it didn't have negative influence to the bone around the implant fixture, and it did not change the surface roughness as well. Researches about the application of TiN coating to the abutment screw are not enough.…”

STATEMENT OF PROBLEMScrew loosening has been a common complication and still reported frequently.PURPOSEThe purpose of this study was to evaluate abrasion of the implant fixture and TiN coated abutment screw after repeated delivery and removal with universal measuring microscope.MATERIAL AND METHODSImplant systems used for this study were Osstem and 3i. Seven pairs of implant fixtures, abutments and abutment screws for each system were selected and all the fixtures were perpendicularly mounted in liquid unsaturated polyesther with dental surveyor. After 20 times of repeated closing and opening test, the evaluation for the change of inner surface of implant and TiN-coated abutment screw, and weight loss were measured. Mann-Whitney test with SPSS statistical software for Window was applied to analyze the measurement of weight loss.RESULTSTiN-coated abutment screws of Osstem and 3i showed lesser loss of weight than non-coated those of Osstem and 3i (P < .05, Mann-Whitney test).CONCLUSIONConclusively, TiN coating of abutment screw showed better resistance to abrasion than titanium abutment screw. It was concluded that TiN coating of abutment screw would reduce the loss of preload with good abrasion resistance and low coefficient of friction, and help to maintain screw joint stability.

“…In addition, the dental implant is also required to have hard tissue compatibility because it is seated tightly in the alveolar bone. For hard tissue compatibility, surface-modified dental implants using hydroxyapatite coating or titanium nitride coating are already available on the market 1,2) . Apart from surface modification by coatings, increasing the roughness of dental implant surface by sandblasting or by machined grooves are also alternative techniques that are widely known to improve hard tissue compatibility 3,4) .…”

Effect of UV Irradiation on the Shear Bond Strength of Titanium with Segmented Polyurethane through .GAMMA.-mercapto Propyl Trimethoxysilane

The objective of this study was to investigate the effect of UV irradiation on shear bond strength between a titanium (Ti) and a segmented polyurethane (SPU) composite through γ-mercapto propyl trimethoxysilane (γ-MPS). To this end, the shear bond strength of Ti/SPU interface of Ti-SPU composite under varying conditions of ultraviolet ray (UV) irradiation was evaluated by a shear bond test. The glass transition temperatures of SPU with and without UV irradiation were also determined using differential scanning calorimetry. It was found that the shear bond strength of Ti/SPU interface increased with UV irradiation. However, excessive UV irradiation decreased the shear bond strength of Ti/SPU interface. Glass transition temperature was found to increase during 40-60 seconds of UV irradiation. In terms of durability after immersion in water at 37℃ for 30 days, shear bond strength was found to improve with UV irradiation. In conclusion, UV irradiation to a Ti-SPU composite was clearly one of the means to improve the shear bond strength of Ti/SPU interface.
