“…Titanium is a material that has low density, high resistance, especially resistance to corrosion, thermal transmittance, and perfect biocompatibility [1–5]. Due to the advantages brought about by these properties, titanium is now used frequently in prosthetic applications in dentistry [6]. Pure titanium and titanium alloys are used as a framework material in dentistry, including in crown-bridge restorations, implant-supported dentures, and removable dentures [3, 6, 7].…”

“…Due to developing technologies, titanium is now produced with computer-aided design/computer-aided manufacturing (CAD/CAM) systems, and problems that occurred during casting have been eliminated [7]. Removable partial dentures are generally produced with the combined use of polymethyl methacrylate (PMMA) and metal [6, 8]. At the end of the follow-up process of a clinical trial that involved removable partial dentures with a titanium base, it was found that there were no clinical problems and that the only technical problem encountered was inadequate adhesiveness with acrylic resin [1].…”

“…The success of the bond between metal alloys and PMMA allows the denture to be long lasting [3]. The complication that is frequently encountered with these materials is the debonding of the acrylic resin from the metal [3, 6, 8]. The reason for this debonding is the difference between the thermal expansion coefficients of the metal alloy and the acrylic resin and the shrinking of the acrylic resin due to polymerization [3, 6, 8, 9].…”

Objectives. The aim of this study is to investigate the shear bond strength of an acrylic resin to titanium after different surface treatment methods. Material and Methods. A total of seventy-two disc-shaped specimens (10 mm×10 mm×2 mm) were prepared from titanium alloy. The specimens were randomly allocated to six equal groups: Group S (sandblasting), Group MP (metal primer), Group 10W (fiber laser 10 W), Group 20W (fiber laser 20 W), Group 10WMP (fiber laser 10 W+metal primer), and Group 20WMP (fiber laser 20 W+metal primer). All of the specimens were thermocycled up to 5000 cycles. After thermal cycling, a shear bond strength test was conducted. The shear bond strength data were analyzed with one-way ANOVA and Tukey’s post hoc pairwise comparisons (p<0.05). Results. While the highest values were determined in Group MP, the lowest values were observed in Group S. Additionally, Group MP exhibited significantly higher shear bond strength values than any of the other groups (p<0.05) except Group 10WMP. Similar results were observed between Group MP and Group 10WMP (p>0.05). The groups in which a metal primer was applied (Group MP, 10WMP, and 20WMP) showed significantly higher values than Group S. The shear bond strength values of Group 10W and Group 20W were similar. Conclusions. The application of a metal primer significantly improved the bond strength of acrylic resin to titanium. Fiber laser application may be an alternative method to sandblasting for improving the bond strength of acrylic resin to titanium.

Aim: Aims and objectives of the study were to measure shear bond strength of rebonded orthodontic brackets after using different enamel reconditioning techniques including (Diamond bur, Air abrasion with Aluminum Oxide particles, Ultra Sonic scaler, CO 2 laser ).Subjects and methods : This in vitro study consists of five groups with ten samples in each group. Each sample was bonded with a metal bracket. After debonding, reconditioning of the tooth surface was performed by the finishing Diamond bur, Air abrasion, Ultra Sonic Scaler and Fractional CO 2 Laser . Rebonding of the reconditioned teeth was again performed. Universal testing machine was used to evaluate the shear bond strength of the orthodontic brackets. Enamel surface topography was evaluated using scanning electron microscope. Results: The maximum average score of shear bond strength was in the LASER Group (16.4 Mega Pascal ) (MPa) followed by Ultra Sonic Scaler (16.2MPa), The Control Group (14.9MPa), Sand blasting Group (14.6MPa), at last the Diamond Burs group (11.3MPa) . There was a relationship between surface roughness and the bond strength achieved. The method which created a smoother uniform surface achieved the higher shear bond strength. Conclusions: Fractional CO 2 Laser, Ultra Sonic scaler and Air abrasion can be used as preferred method of reconditioning the tooth surface after bond failure instead of diamond burs to achieve optimal bond strength of rebonded brackets.

Objective. This study investigated the effect of air-abrasion and erbium:yttrium-aluminum-garnet (Er:YAG) laser treatments on push-out bond strength (PBS) between hard relining material and metal housing of an overdenture attachment system. Material and Methods. A total of 36 metal housings were randomly divided into 3 subgroups according to surface pretreatments (n=12): Control (no surface treatment; C), air-abrasion (A), and Er:YAG laser (L). Surface roughness (Ra) of specimens was determined using a profilometer. One additional specimen per group was evaluated by scanning electron microscopy (SEM). The hard relining material was bonded to metal housings, and a PBS test was performed using a universal testing machine. Data were statistically analyzed using 1-way analysis of variance (ANOVA), Tukey’s honestly significant difference (HSD), and Tamhane’s T2 tests (α=.05). Results. C and L groups showed the lowest and highest Ra values, respectively. The mean Ra of the A group was statistically different from the mean values of the C and L groups (P<.001). The L group showed higher PBS values than the C group (P<.05), whereas the A group exhibited statistically similar PBS values to both C and L groups (P>.05). Conclusions. Air-abrasion did not significantly increase the bond strength between the metal housing and hard relining material. Er:YAG laser irradiation noticeably improved the PBS but caused surface microcracks.
