Laser ablation of bone for implant osteotomy preparation-modeling and an ex vivo validation study.
Article in Lasers in medical science, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 2 papers.
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
Mechanical drilling is currently a universal standard for implant osteotomy site preparation. Without proper cooling, high frictional heat can be generated inside the bone during drilling which may be detrimental for osteocyte survival. Mechanical fracture of bone near a drill bit surface can also impede the osseointegration process. Our new concept is to use a rapid laser ablation model for dental implant osteotomy preparation to minimize adverse effects on the bone from mechanical and thermal damages. A mathematical model was developed to detail the temperature and energy distribution within bone under laser irradiation. Thermal and energy transfer in bone was predicted during laser interaction using finite element simulations. Various parameters of laser irradiation settings were analyzed. The best designed laser irradiation condition was derived from our theoretic modeling in terms of thermal and mechanical characteristics for osteotomy. We also validated our theoretical prediction with an ex vivo animal bone study. We conclude that a smooth and clean surface was successfully formed with laser power of 10 W, scanning speed of 600 mm/s, and scanning interval of 20 μm. We also achieved the highest removal rate of 0.63 mm
