Objectives: To compare the stability of implant surface treated by dual acid etching (Porous)and implants with anodized surface (Vulcano) over a period of 16 weeks after installation. Methods: it will be a clinical study with individuals with missing teeth requiring rehabilitation with dental implants in the maxilla and that fulfill the study inclusion criteria. The research sites will be randomized into two groups: the control group patient's sites receive implant surface treated by dual acid (AR Torque Porous, Connection Implant Systems, Aruja, Brazil) and in the test group implants with anodized surface (AR Torque Vulcano-Actives, Connection Implant Systems, Aruja, Brazil). The evaluation of the stability of the implants will be made over 16 weeks, through resonance frequency analysis with Osstell (Integration Diagnostics AB, Gothenburg, Sweden). Data will be analyzed using descriptive statistics and comparative.

Each week since the surgery the implant stability will be measure with the Osstell mentor to verify the resonance frequence analysis, using the smartpeg number 21

implant loss
During the osseointegration, if the implant lose his stability and if it show spin and if the patient have pain, the implant will be removed and the implant will be considered lost
Time frame: 4 months
ISQ analysis
Since the implant installation, for the next 8 weeks, and after for the next 4 months, the implant stability will be measure with the Osstell, that will return a number between 0 and 100. This represents the Implant Stability Quotient (ISQ). The difference between the ISQ results will be the secondary outcome measure
Time frame: 6 months
