Development of dental implant drill with detection mechanism of bone quality change.
Article in International journal of implant dentistry, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
purposeThis study aims to develop and evaluate a dental implant drill system capable of preventing maxillary sinus membrane perforation, a common complication in cases with limited alveolar bone height, particularly in the maxillary molar region. The primary objective is to design a mechanism that autonomously detects changes in bone quality and halts drill rotation upon reaching the sinus floor.
methodsA novel dental implant drill incorporating an integrated bone quality detection mechanism was developed. The system includes a centrally mounted detector that actuates a switch controlling drill rotation. When cortical bone is penetrated and softer tissue is encountered, the detector extends outward, interrupting power to the motor. A penetration test was conducted using a 5 mm thick wooden board as a surrogate bone model to evaluate the drill's response to cortical penetration.
resultsExperimental trials demonstrated that the drill automatically ceased rotation upon advancing approximately 0.47 mm beyond a simulated bone surface. Given that the maxillary sinus membrane is typically less than 1 mm in thickness, this minimal protrusion indicates a significantly reduced risk of perforation.
conclusionThe proposed drill system effectively detects transitions in bone quality and prevents over-penetration, offering a promising solution for enhancing surgical safety during maxillary implant procedures.
