ABSTRACT  The aim was to: (i) compare changes among primary and secondary implant stability between immediate and early loaded implants in edentulous maxilla, (ii) evaluate oral health related quality of life (OHRQoL) and (iii) determine patient satisfaction with 6-implant supported fixed full-arch dentures. A prospective, randomized controlled clinical trial was conducted on 24 edentulous maxilla patients. The BLT SLActive® implants in 12 patients were immediately loaded with temporary restorations while12 patients did not receive temporary restorations. Definitive (final) dentures were delivered to all patients after 6 weeks. Stability of the implants were assessed by Insertion Torque (IT) and Resonance Frequency Analysis (RFA). Oral Health Impact Profile-19 ( OHIP-19) questionnaire was used to evaluate OHRQoL and a Visual Analogue Scale (VAS) for patient satisfaction. The IT value of implants assigned for immediate and early loading group was 27.17±9.55Ncm and 25.01±11.06Ncm, respectively. Changes in implant stability from baseline to week 6 were similar in both groups when measured by Penguin ® (p=0.881) and Ostell ® (p= 0.828).  Patients in the immediate load group reported significantly lower OHIP physical pain scores (p=0.016),  OHIP psychological disability score (p=0.046) and significantly higher VAS function score (p=0.009) and VAS aesthetics score (p=0.009). Implant loading protocols don't have a significant effect on the change in implant stability 6 weeks after implantation, however, immediate loading significantly improves OHRQoL and satisfaction of patients with maxillary edentulism treated by fixed full-arch dentures. Future trials will determine the role of immediate loading protocol in clinical scenarios with various amounts of available jaw bone using different numbers of implants to retain a fixed prosthetic restoration in the edentulous maxilla.
