Abstract

Objective: To evaluate the clinical and radiographic outcomes associated with dental implants subjected to different loading protocols in the posterior maxillary region.

Patients and methods: This clinical study included 16 implants placed in patients seeking the rehabilitation of single/multiple teeth in the posterior maxillary region. The patients were distributed randomly into three groups according to the loading protocol; the 1st group received four implants subjected to conventional loading protocol, the 2nd group received six implants subjected to early loading protocol, additionally the 3rd group received six implants subjected to immediate loading protocol. The evaluation was done immediately after crown cementation (T1), and after 6 months (T2) and 12 months (T3) to assess implant stability and marginal bone level and bone loss around the implants.

Results: This study included 14 patients with an average age of 34.79+9.17 years. There were no statistically significant differences between studied groups regarding age, sex, implant position, length, and width (p=0.642, p=0.260, p=0.822, p=0.053, and p=0.317 respectively). There were no statistically significant differences between studied groups regarding stability at different follow-up periods (P=0.06 at T1, P=0.07 at T2, P=0.150 at T3). However, there were significant differences between group 1 vs group 2 at T1 and T2 (P=0.018, P=0.028) respectively. Regarding mean bone loss, there were statistically significant differences between studied groups specifically T2 from T1 (P=0.01) and T3 from T1 (P<0.001).

Conclusions: Earlier loading positively enhances osseointegration around immediately loaded and early-loaded implants when compared with conventionally loaded dental implants. On the other hand, greater bone loss was observed with immediately loaded and early-loaded implants than with conventionally loaded implants.
