Immediate loading of implants inserted in implant beds prepared with conventional or ultrasonic osteotomy in the esthetic zone: Randomized clinical trial with 12-month follow-up

This randomized clinical trial compared 12-month outcomes of narrow platform implants (NP) or regular platform implants (RP) in beds prepared with conventional versus ultrasonic osteotomy and immediately loaded. Patients requiring narrow (3.0 mm) or regular (3.75 mm) implants in the upper esthetic zone were randomly allocated for conventional (10 NP, 15 RP implants) or ultrasonic (10 NP, 15 RP) osteotomy. Primary and secondary implant stability, operation time, patient discomfort, and probing depths were evaluated after different time periods. Implant bed preparation time was longer (p
