May dental implant macro and microgeometry modifications influence peri-implant bone repair in smokers? A randomized clinical trial.
Trial report in BMC oral health, 2024. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
backgroundThis split-mouth, double-masked, randomized clinical trial aimed at evaluating the impact of different macro geometries and nano topographical modifications on peri-implant bone repair in smokers.
methodsThirty-two patients who smoked at least ten cigarettes/day, with the need of a single maxillary or mandibular implant bilaterally, received two implants randomly assigned to DA - Dual Acid-Etched implants (n = 32); HCAN - healing chambers and activated nano surface (n = 32). Implant stability quotient (ISQ) was evaluated 07, 30, 60, 90, and 120 days after implant placement. Levels of bone and angiogenic markers were quantified in the peri-implant fluid after 07, 15, 30, 90, and 120 days of implant insertion. HCAN implants have a higher ISQ than DA implants at 60 days (p < 0.05).
resultsPLGF levels were lower for HCAN implants than for DA implants at 07-day period (p < 0.05). Besides, HCAN implants presented higher levels of OPG at 30 days and OPN, BMP-9, FGF-1, PLGF, and VEGF at 90 days, compared to DA implants (p < 0.05). The levels of EGF were higher for HCAN implants at 15, 90, and 120 days compared with DA implants (p < 0.05). HCAN implants also showed lower levels of TNF-α at 07 days in comparison to DA implants (p < 0.05) but had higher levels of DKK1 at 30 days, while DA implants presented higher levels of this marker at 90 days (p < 0.05).
conclusionMacro geometry and nano topographical modifications positively modulated the bone and angiogenic factors, resulting in higher production of these markers during early peri-implant bone healing and having a positive effect on implant stabilization in smokers.
