ABSTRACT
PURPOSE/AIM: Robotic-assisted techniques have the potential to revolutionize dental implantology by offering enhanced precision, accuracy, and clinical outcomes compared to computer-assisted implant placement techniques. This study aimed to evaluate the accuracy of dental implant placement using robot-assisted implant surgery in vitro settings. METHODS: An unrestricted search of indexed databases along with a manual search was performed up to March 2024. In vitro, studies comparing the positioning accuracy of robotic systems in dental implant placement of planned pre-operative coordinates and postoperative outcomes in phantom and simulated models were included. QUIN Tool was used to assess the quality of the included studies. RESULT: A total of 13 in vitro studies were included. All studies except one used entry, exit, or angle deviation as parameters to assess the accuracy of implants placed on phantom models or simulated virtual implant placement. Overall, pooled entry deviations were 0.72 ± 0.68 mm, exit deviations were 0.86 ± 0.92 mm, and angular deviations were 1.47 ± 1.610 favoring robot-assisted implant surgery. CONCLUSION: Based on the current evidence, robotic-placed implants have the potential to revolutionize dental implantology by offering enhanced precision, accuracy, and clinical outcomes compared to dynamic and static computer-assisted implant surgery techniques.
ABSTRACT
PURPOSE: To evaluate self-perceived pain levels in the Hyrax compared to other types of maxillary expansion (ME) appliances in growing patients. METHODS: An unrestricted search of indexed databases and manual searching were performed up to October 2022. Randomized controlled trials (RCTs) comparing the Hyrax appliance with other ME appliances were included. Data screening, extraction, and Risk of Bias (RoB) assessment with the Cochrane tool were performed by two authors. RESULTS: Six RCTs were included. The number of participants in the included RCTs ranged between 34 to 114 and included both male and female growing patients. Various tools were used to measure self-perceived pain including the Graphic Rating Scale for Pain, the Wong-Baker Faces Pain Scale, the Numerical Rating Scale, the visual analogue scale, and a questionnaire. One RCT reported that pain intensity in patients treated with the Hyrax was higher than in the Haas appliance, with a statistically significant difference limited to the first day. Two RCTs reported that pain intensity in patients treated with the Leaf expander was lower than in the Hyrax during the first 7 days of treatment. Two RCTs reported no significant differences in pain intensity between the Hyrax and other ME appliances. One RCT reported that pain intensity in patients using the computer-guided skeletal ME appliance was higher than in the Hyrax appliance at the first day after expansion. Four RCTs had a high RoB, and two RCTs had a moderate RoB. CONCLUSIONS: Within the limitations of the present systematic review and based on the currently available evidence, it is challenging and inconclusive to identify the best maxillary expansion appliances, regarding pain levels for growing patients.
