The present case report describes a successful surgical case of coronectomy of a fully impacted lower third molar in close relationship with the Inferior Alveolar Nerve (IAN) that was trapped in the furcation roots of the lower third molar. It was associated with a dentigerous cyst. Dynamic Navigation (DN) was used to minimize iatrogenic injuries to the IAN. Coronectomy and cyst removal were successfully performed. High surgical accuracy was provided thanks to the dynamic navigation system that allows the surgeon to perform the procedures without direct vision during the surgery. No neurological damage or other intraoperative complications occurred. One month later, the patient reported a dental abscess to the left mandibular second molar without wound dehiscence which required antibiotic and endodontic therapy. After 2 years, no long-term postoperative complications were reported and follow-up radiographs showed complete bone mineralization. In conclusion, technological support of DN in Coronectomy seems to avoid IAN injury and reduce postoperative complications.

Background: Auricular defects resulting from congenital anomalies, trauma, or oncologic resection pose significant functional and psychosocial challenges. When autologous reconstruction is not feasible or not desired, implant-retained auricular prostheses represent a reliable alternative with high patient satisfaction. This study aimed to systematically evaluate the clinical performance of craniofacial implants used for auricular prosthetic rehabilitation, focusing on implant survival, prosthetic outcomes, workflow typologies, and complications. A secondary objective was to illustrate the long-term validity of a minimally invasive navigation technique through a clinical case with 6-year follow-up. Methods: A systematic review was conducted according to PRISMA guidelines. Clinical studies published between 2005 and 2025 reporting outcomes of implant-retained auricular prostheses were searched in PubMed and Scopus databases. Data were extracted on implant type, survival rates, prosthetic performance, workflow, and complications. Risk of bias was assessed using appropriate tools based on each study design. Results: A total of thirty-two studies were included, comprising fifteen case reports, fifteen case series, one cohort study, and one prospective observational study. Implant survival was consistently high across all workflow categories, with failures predominantly associated with irradiated or anatomically compromised bone. Prosthetic outcomes were favorable, showing excellent esthetics, stable retention, and high patient satisfaction irrespective of manufacturing method, although digital and navigation-assisted workflows improved reproducibility, symmetry, and planning precision. Complication rates were low and generally limited to mild peri-abutment inflammation manageable with conservative care. The clinical case confirmed these findings, showing stable osseointegration, healthy soft tissues, and uncompromised prosthetic function at 6-year follow-up. Conclusions: Implant-retained auricular prostheses show predictable long-term success, independent of whether traditional, hybrid, or fully digital workflows are employed. Digital technologies enhance surgical accuracy, minimize morbidity, and streamline prosthetic fabrication, although high-quality comparative studies remain limited.

Coronectomy is a conservative surgical technique used to manage deeply impacted mandibular third molars at high risk of inferior alveolar nerve injury. Precise execution is essential to avoid complications, particularly in cases with limited surgical access. Dynamic navigation (DN) systems may enhance accuracy and safety in such procedures. This report describes the 5‐year follow‐up of a DN‐assisted coronectomy in a 42‐year‐old patient presenting with recurrent pericoronitis and a pericoronal lesion associated with a deeply impacted lower third molar. Preoperative planning was performed using cone beam computed tomography (CBCT), and DN was employed intraoperatively to guide surgical instrumentation in real time. The procedure was carried out according to a standardized protocol, including crown sectioning, root reduction, and primary closure. No intraoperative or early postoperative complications were observed. At 5‐year follow‐up, the patient was asymptomatic. Clinical examination showed complete mucosal healing and normal probing depths. Radiographic evaluation revealed retained roots without signs of pathology and bone formation distal to the second molar. This case may highlight the potential role of DN in improving surgical control during coronectomy in anatomically complex situations, contributing to a favorable long‐term clinical and radiographic outcome.

Implant rehabilitation in the posterior maxilla with severe vertical bone atrophy remains clinically challenging, particularly when bone augmentation procedures are not feasible or are refused by the patient. The use of ultrashort implants combined with dynamic navigation has been proposed as a minimally invasive alternative in selected cases; however, long‐term clinical evidence in the maxilla is still limited. This case report describes the 10‐year clinical and radiographic outcomes of a single 4‐mm ultrashort implant placed in the posterior maxilla using dynamic navigation technology. A 47‐year‐old nonsmoking female patient presented with a single edentulous maxillary first molar and severe vertical bone resorption (≤ 5 mm). The patient declined bone augmentation and fixed partial denture therapy. Implant placement was planned and performed under dynamic navigation guidance, followed by restoration with a single implant‐supported crown. Clinical and radiographic follow‐up was conducted regularly up to 10 years after prosthetic loading. Throughout the follow‐up period, no biological or prosthetic complications were observed. Peri‐implant soft tissues remained healthy, with no bleeding on probing or suppuration. Radiographic evaluation using standardized periapical radiographs revealed a mean marginal bone loss of 0.35 mm at 10 years. The implant‐supported crown maintained stable function and structural integrity, and the patient reported high satisfaction with the treatment outcome. Within the limitations of a single case report, these findings suggest that the combination of dynamic navigation and ultrashort implants may represent a reliable and minimally invasive treatment option for single implant rehabilitation in severely atrophic posterior maxillary sites. Further prospective studies with larger sample sizes and long‐term follow‐up are required to confirm the predictability and reproducibility of this approach.
