“…A number of in vivo studies have reported that the sur-face chemistry of titanium implants plays an important role for osteointegration [11]. The study importance of manufacturer in implant market is focused on the micro and macro design of the fixtures [12][13][14][15][16]. Related to the composition of the alloy of the fixtures, the researcher does not give a great importance, furthermore almost all products are classified as Type 5 Titanium.…”

Nowadays the implants rehabilitations are used deeply by clinicians. The importance to technological improvement is working to find the best surface of the fixture to obtain a good and stable osteointegration. By the use of the Energy Dispersive X-ray (EDX) analysis and the X-ray Photoemission Spectroscopy (XPS) evaluate the surface quality of commercial implants. The XPS analysis was made to evaluate the chemical elements that compose the material surface of the implant and determine the state of atomical connections. The EDX analysis was performed to evaluate the characteristic qualitative and quantitative of the metallic alloys of the fixtures to determinate the pureness of the metals under the surfaces. The major difference found between the samples is the amount of surface aluminum (in oxidized state, alumina), which in the samples 2 appears to be more than an order of magnitude greater (12 times). In Sample 2 there are traces of P, Na and Cl not present in Sample 1. The presence of C, O, N, Si and Ca are similar on both samples (1 and 2). Now, in the market there are many different dental implants. All the producers are working hard on micro and macro design of the fixtures, but not so many attentions is spent on the type of the alloy composing the implant. From this analysis, it is observed that different Type 4 dental implant are not so similar by composition. Moreover, the pure Titanium is well tolerated by biological tissues, on the other hand is not well known if the presence of other materials can influence the biological reaction. The samples of the fixture analyzed present different composition of the alloy, although both classified as Type 5 Titanium. Further studies on this topic are needed to understand if these differences of alloy composition can influence the clinical outcome.

Purpose:Implant surface treatments that improve early osseointegration may prove useful in long-term survival of uncemented implants. We investigated Acid Etching and Plasma Cleaning on titanium implants.Methods:In a randomized, paired animal study, four porous coated Ti implants were inserted into the femurs of each of ten dogs. PC (Porous Coating; control)PC+PSHA (Plasma Sprayed Hydroxyapatite; positive control)PC+ET (Acid Etch)PC+ET+PLCN (Plasma Cleaning) After four weeks mechanical fixation was evaluated by push-out test and osseointegration by histomorphometry.Results:The PSHA-coated implants were better osseointegrated than the three other groups on outer surface implant porosity (p<0.05) while there was no statistical difference in deep surface implant porosity when compared with nontreated implant. Within the deep surface implant porosity, there was more newly formed bone in the control group compared to the ET and ET+PCLN groups (p<0.05). In all compared groups, there was no statistical difference in any biomechanical parameter.Conclusions:In terms of osseointegration on outer surface implant porosity PC+PSHA was superior to the other three groups. Neither the acid etching nor the plasma cleaning offered any advantage in terms of implant osseointegration. There was no statistical difference in any of the biomechanical parameters among all groups in the press-fit model at 4 weeks of evaluation time.

Interaction between implant surface and surrounding bone influences implant fixation. We attempted to improve the bone-implant interaction by 1) adding surface micro scale topography by acid etching, and 2) removing surface-adherent pro-inflammatory agents by plasma cleaning. Implant fixation was evaluated by implant osseointegration and biomechanical fixation.The study consisted of two paired animal sub-studies where 10 skeletally mature Labrador dogs were used. Grit blasted titanium alloy implants were inserted press fit in each proximal tibia. In the first study grit blasted implants were compared with acid etched grit blasted implants. In the second study grit blasted implants were compared with acid etched grit blasted implants that were further treated with plasma sterilization. Implant performance was evaluated by histomorphometrical investigation (tissue-to-implant contact, peri-implant tissue density) and mechanical push-out testing after four weeks observation time.Neither acid etching nor plasma sterilization of the grit blasted implants enhanced osseointegration or mechanical fixation in this press-fit canine implant model in a statistically significant manner.
