Accuracy of robotic-assisted implant placement in second molars combined with step drills and manual-automatic switching function: a retrospective study.
Article in BMC oral health, 2025. 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
backgroundNowadays, robotic computer-assisted implant surgery (r-CAIS) has drawn great attention in implant dentistry; however, the clinical application of r-CAIS for limited operating space such as the second molar region, has not been demonstrated. Thus, this study aimed to evaluate the accuracy of r-CAIS in second molars in combination with step drills and manual-automatic mode switching function.
methodsPatients who lost second molars and underwent r-CAIS were enrolled in this study. The positioning marker was installed preoperatively, and a cone-beam computed tomography (CBCT) scan was subsequently performed. The CBCT data were subsequently transferred into the robotic software, and a preoperative surgical plan was generated. After marker registration and calibration, the implant osteotomy was completed by the robotic arm under the control of the surgeons. Owing to the limited operating space in the second molar region, the operation mode of r-CAIS was switched between manual and automatic modes, and step drills were used in combination. Patients underwent postoperative CBCT, and the accuracy was evaluated using the CBCT data between the planned and placed implants.
resultsA total of 16 patients were enrolled in this study, and no adverse events occurred during or after surgery. The mean global coronal, apical and angular deviations were 0.43 ± 0.10 mm (95%CI: 0.38 to 0.49 mm), 0.44 ± 0.10 mm (95%CI: 0.38 to 0.49 mm), and 0.88 ± 0.53°(0.60 to 1.16°), respectively.
conclusionsr-CAIS can achieve high accuracy in the second molar region when combined with step drills and manual-automatic mode switching function. Further prospective studies are needed to validate the effects.
