Design outcomes

Primary

Measure	Time frame
Pain perception measured using the Visual Analogue Scale during the first week after surgery	—

Secondary

Measure	Time frame
1. Implant insertion torque measured by manual torque wrench immediately after implant placement 2. Implant Stability Quotient (ISQ) obtained using resonance frequency analysis (RFA) measured by specific device Osstell® immediately after implant placement 3. Quality of life measured using the Oral Health Impact Profile 14 translated in Portuguese during the first week after surgery 4. Implant osseointegration success rate measured using clinical examination at 6 months after surgery 5. Patient registration of analgesic medication usage during the first week after surgery	—
