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.
