    期刊:Journal of pharmacy & bioallied sciences
    日期:2024-06-07
    DOI :10.4103/jpbs.jpbs_260_24
    Background:Wisdom tooth extraction often requires various surgical techniques due to differences in tooth position, root morphology, and patient characteristics. This research aims to compare traditional surgical extraction with minimally invasive techniques such as piezo surgery and laser-assisted extraction, as well as extraction with the aid of 3D imaging and navigation systems. Methods:Patients requiring wisdom tooth extraction were randomly assigned to one of the surgical technique groups. Preoperative imaging assessed tooth position and root morphology. Intraoperative variables and postoperative outcomes were recorded, including pain levels, swelling, and healing time. Patient-reported outcomes were assessed using standardized questionnaires. Results:Piezo surgery, 3D imaging, and navigation-guided extraction techniques demonstrated a shorter mean duration of surgery and lower incidence of intraoperative complications compared to traditional extraction and laser-assisted extraction. Postoperative outcomes were superior in the 3D imaging and navigation-guided extraction group, with lower pain scores, reduced swelling, and faster healing time. Conclusion:Advanced imaging-guided techniques, particularly 3D imaging and navigation-guided extraction, offer significant benefits for patients undergoing wisdom tooth extraction by improving surgical precision, minimizing complications, and enhancing postoperative outcomes. Incorporating these technologies into routine practice can optimize patient care and outcomes in oral surgery.

    2. Accuracy of computer-assisted dynamic navigation when performing coronectomy of the mandibular third molar: A pilot study.
    期刊:Journal of dentistry
    日期:2023-10-26
    DOI :10.1016/j.jdent.2023.104762
    OBJECTIVES:The study represents a preliminary evaluation of the accuracy of the dynamic navigation system (DNS) in coronectomy of the mandibular third molar (M3M). METHODS:The study included participants with an impacted M3M near the inferior alveolar canal. The coronectomy planes were designed before the surgery using cone-beam computed tomography (CBCT) imaging data and then loaded into the DNS program. Intraoperatively, the navigation system was used to guide the complete removal of the target crown. Postoperative CBCT imaging was used to assess any three-dimensional deviations of the actual postoperative from the planned preoperative section planes for each patient. RESULTS:A total of 12 patients (13 teeth) were included. The root mean square (RMS) deviation of the preoperatively designed plane from the actual postoperative surface was 0.69 ± 0.21 mm, with a maximum of 1.45 ± 0.83/-1.87 ± 0.63 mm deviation. The areas with distance deviations < 1 mm, 1-2 mm, and 2-3 mm were 71.97 ± 5.72 %, 22.96 ± 6.57 %, and 4.52 ± 2.28 %, respectively. Most patients showed extremely high convexity of the surface area located in the mesial region adjacent to the base of the extraction socket. There was no observable evidence of scratching of the buccolingual bone plate at the base of the extraction socket by the handpiece drill. CONCLUSIONS:These results provide preliminary support for the use of DNS-based techniques when extracting M3M using a buccal approach. This would improve the accuracy of coronectomy and reduce the potiential damage to the surrounding tissue. CLINICAL SIGNIFICANCE:DNS is effective for guiding coronectomy.
  • 3. Surgical extraction of a sublingually-displaced retained root with the aid of a magnetic field-based dynamic navigation system: a case study.
    期刊:Journal of the Korean Association of Oral and Maxillofacial Surgeons
    日期:2024-12-31
    DOI :10.5125/jkaoms.2024.50.6.367
    The submandibular displacement of a mandibular third molar residual root presents major challenges to oral and maxillofacial surgeons due to the proximity to critical anatomical structures such as the lingual nerve and sublingual artery. Preoperative imaging can approximate the location of the residual tooth root; however, accurately determining its exact position is difficult because of the dynamic nature of the mandible and the difficulty of real-time synchronization of imaging. This study presents the successful extraction of a residual mandibular third molar root in a 67-year-old female patient achieved using a magnetic field-based navigation system. The sublingually-displaced residual root was localized using the navigation system, marked using a virtual implant placement, and positioned by a hand piece using synchronized real-time sensor data. The root was successfully removed with a minimally-invasive approach. No complications occurred postoperatively, and follow-up showed no major issues. Due to the small size of the marker, ease of calibration, and independence from visual obstacles, magnetic field-based navigation systems are a promising tool for the removal of residual roots displaced into adjacent soft tissue.

    4. A prospective randomized study on the efficacy of real-time dynamic navigation in deep horizontal mandibular third molar extractions.
    期刊:BMC oral health
    日期:2024-10-16
    DOI :10.1186/s12903-024-05016-9
    PURPOSE:This study aimed to evaluate the clinical efficacy of applying real-time dynamic navigation (RDN) in the extraction of deep horizontal mandibular impacted third molars, hypothesizing that RDN reduces surgical time and minimizes the risk of injury to adjacent anatomical structures. METHODS:A prospective study was conducted on 160 patients aged between 18 and 37 years with deep horizontal impaction of the mandibular third molar. The participants were randomly assigned to either the experimental group (receiving RDN-assisted extractions) or the control group (undergoing traditional extraction methods). Preoperative planning utilized cone beam computed tomography (CBCT) and Mimics software for the accurate localization and segmentation of impacted teeth. Parametric data were analysed via an independent t test for intergroup comparisons, and significance was set to p < 0.05. RESULTS:In the experimental group, an average of 11 ± 1 min was required for preoperative planning via RDN, which was not required in the control group. The setup of the navigation system took an average of 4 ± 1 min in the experimental group and 0 min in the control group. The experimental group demonstrated a significantly shorter average surgical time (22 ± 3 min) than did the control group (36 ± 3 min). The differences in the preoperative design time, surgical time, and complication rates between the two groups were statistically significant (p = 0.005). Additionally, the RDN group reported no complications related to adjacent tooth damage or nerve injury. CONCLUSION:The precision, safety, real-time guidance of RDN supports its use in complicated dental extractions, which would introduce a new era of oral and maxillofacial surgery.

    5. The Use of Dynamic Navigation Systems as a Component of Digital Dentistry.
    期刊:Journal of dental research
    日期:2023-12-15
    DOI :10.1177/00220345231212811
    The development of dynamic navigation system (DNS) has facilitated the development of modern digital medicine. In the field of dentistry, the cutting-edge technology is garnering widespread recognition. Based on the principles of 3-dimensional visualization, virtual design, and precise motion tracking, DNS is mainly composed of a computer, a tracking system, specialized tracer instruments, and navigation software. DNS employs a workflow that begins with preoperative data acquisition and imaging data reconstruction, followed by surgical instrument calibration and spatial registration, culminating in real-time guided operations. Currently, the system has been applied in a broad spectrum of dental procedures, encompassing dental implants, oral and maxillofacial surgery (such as tooth extraction, the treatment of maxillofacial fractures, tumors, and foreign bodies, orthognathic surgery, and temporomandibular joint ankylosis surgery), intraosseous anesthesia, and endodontic treatment (including root canal therapy and endodontic surgery). These applications benefit from its enhancements in direct visualization, treatment precision, efficiency, safety, and procedural adaptability. However, the adoption of DNS is not without substantial upfront costs, required comprehensive training, additional preparatory time, and increased radiation exposure. Despite challenges, the ongoing advancements in DNS are poised to broaden its utility and substantially strengthen digital dentistry.
