## TL;DR

This study compares immediate and delayed loading of dental implants in the posterior mandible using CBCT over one year.

## Contribution

The study provides CBCT-based evidence on bone remodeling differences between immediate and delayed implant loading.

## Key findings

- Both immediate and delayed loading groups achieved 100% implant survival.
- Immediate loading showed slightly higher bone remodeling but within acceptable limits.
- Clinical parameters were comparable between the two groups.

## Abstract

Recent studies emphasize that bone remodeling within the first year is a critical determinant of long-term implant success and marginal
bone loss > 1.5 mm may jeopardize prognosis. Therefore, it is of interest to assess immediate versus delayed loading of implants in
the posterior mandible over one year using CBCT evaluation. Hence, forty patients were treated with single implants allocated to
immediate or delayed loading groups. Outcomes included implant survival, marginal bone changes and peri-implant soft-tissue health. Both
groups achieved 100% survival. CBCT revealed slightly higher bone remodeling in immediate loading, though within clinically acceptable
limits. Clinical parameters were comparable. Immediate loading, under strict case selection, may thus be a viable treatment option in
posterior mandible.
