Abstract
Aims: The current study aims to compare alloys of dental implants and to find the ratio of titanium element (Ti) with different origins which are used by dentists in dental implant to restore the missing teeth. Materials and Methods: Three types of dental implants from Germany, Italy and Korea used in this study for statement the chemical structure of these alloys using (XRD: X-Ray Diffraction) (Model S1TurboSD LECE , BRUKER). Hardness, tensile strength, and flexibility coefficient tested by hardness measuring device Micro Hardness – AMSLER, Germany, 1978. The microstructure of samples obtained by Metrology Microscope (600X), ME-3125, UNION, 1978, Japan. Results: Different elements appeared in each alloy, and the titanium (Ti) ratio was the main one, where the Germany type (95.14%), Italy, (91.21%), while Korea type was the highest (95.21%). Tension Resistance in Germany model (755) N/(mm)2 , Italian (781) N/(mm)2 , and Germany (785) N/(mm)2 . Hardness Vickers (HV) in Germany (277), Italy (285) and for Korean type (287). Modulus of elasticity, in Germany (107) Gpa, in Italy (115) Gpa. and in Korean (107) Gpa. The classification according to the American Society for Testing and Materials found in Germany Ti 3-2.5, Italy Ti6-2-1-1, and in Korean Ti 3-2.5. Conclusions: The Korean sample is best for three reasons the quantity of Titanium, Hardness Vickers (VH) and Tension Resistance are more. The Italy type is found better for Modulus Elasticity, while the Germany type is better in Microstructure. In general, and since, the three types have more than (90%) of Titanium there for all the types of dental implant are good against corrosion from acid and Hydrofluoric (HF)

Dental implants operations began growing strides in Iraq compared to the countries in the world that are working on since time, and these operations have required more useful information to beneficiaries over the extensive experience used in the world for the quality of materials www.rafidaindentj.netSulaiman JMA used by dentists in osseointegrated
This phenomenon was discovered in 1952 by a Swedish professor of orthopedics named Branemark who found that titanium attaches itself to bone when it is implanted in it. [1,2] The current research study focused on three types of dental implants predominant used by dentists which are the Korean, Italian and German, to find the amount of titanium in each alloy and its importance in osseointegrated in addition to the role of other elements and physical properties owned

Summary
Dental implants operations began growing strides in Iraq compared to the countries in the world that are working on since time, and these operations have required more useful information to beneficiaries over the extensive experience used in the world for the quality of materials www.rafidaindentj.net. [1,2] The current research study focused on three types of dental implants predominant used by dentists which are the Korean, Italian and German, to find the amount of titanium in each alloy and its importance in osseointegrated in addition to the role of other elements and physical properties owned. [3] Titanium has long been successfully used as an implant material, and widely used in odontology because of it's excellent characteristics such as chemical inertia, mechanical resistance, low density, absence of toxicity, resistance for corrosion and biocompatibility.[4]. The addition of alloying elements to titanium enables it to have a wide range of properties: Aluminum tends to stabilize the α - phase; it increases the transformation temperature from α - to β -phase. [9] Commercially pure titanium (CP-Ti) and titanium alloys are frequently used as dental and orthopedic implant materials because of their excellent mechanical strength, chemical stability and biocompatibility. Changes in the physico-chemical properties of Ti dioxide will modulate protein adsorption and further cell attachment.[13]
