# Comparison of clinical and radiographic outcomes for platform-switched bone-level and platform-matched tissue-level implants

## TL;DR

This study compared two dental implant designs and found no significant differences in their clinical and radiographic outcomes over 8 months.

## Contribution

The study provides evidence that platform-switched bone-level and tissue-level implants perform similarly in terms of bone preservation and stability.

## Key findings

- Both implant groups showed comparable peri-implant soft-tissue parameters.
- Crestal bone loss and implant stability were similar between the two groups at 8 months.
- TL and BL implants demonstrated equivalent clinical and radiographic performance.

## Abstract

Crestal bone preservation is essential for dental implant longevity, yet evidence comparing tissue-level (TL) and bone-level (BL) designs
remains inconsistent. Therefore, it is of interest to evaluate 30 implant sites assigned to TL (n=15) or platform-switched BL (n=15) implants
to compare clinical outcomes, crestal bone levels, and implant stability. Clinical parameters including bleeding on probing, plaque index,
probing depth, gingival margin position, and clinical attachment level were recorded at 2 and 8 months, while CBCT assessed crestal bone changes
and resonance frequency analysis measured implant stability. Both groups showed comparable peri-implant soft-tissue parameters and similar
crestal bone loss at 8 months, with no significant differences in implant stability. Both TL and BL implant designs demonstrated equivalent
clinical and radiographic performance, confirming their suitability for implant-supported restorations.
