2.2. Implant Macrogeometries and Surface Treatment
In the present study, two implant macrogeometries of Morse taper connection manufactured in Grade-4 titanium (Implacil De Bortoli, São Paulo, Brazil) were used, as described in the following: a DuoCone implant, which presents a regular conical macrogeometry with progressive trapezoidal threads and a cervical plane area of 1 mm; whereas, the Maestro implant shows a conical macrogeometry with progressive trapezoidal threads, a cervical plane area of 0.5 mm, and healing chambers between the threads. All implants received an equal surface treatment by blasting with 50–100 µm TiO
