Novel Ultrasonic Device to Measure the Distance From the Bottom of the Osteotome to Various Anatomic Landmarks

Abstract

The results of this in vivo study support the value of this ultrasonic system in measuring the residual osseous depth from the bottom of the osteotome to the roof of the IAC.

Ultrasonic Assessment of Mucosal Thickness around Implants: Validity, Reproducibility, and Stability of Connective Tissue Grafts at the Buccal Aspect

“…These factors may be responsible for the fact that the device has not become part of the standard armamentarium of the clinician. Nevertheless, the ultrasound has a broad application in various dental fields: to measure blood supply to alveolar bone, to evaluate bone quantity and quality before implantation, to try to improve hard and soft tissue healing and accelerate osseointegration of dental implants, to locate submerged implants installed in a two‐stage protocol, and even to measure the residual osseous depth from the bottom of the osteotome to various anatomic landmarks …”

Accuracy of vertical height measurements on direct digital panoramic radiographs using posterior mandibular implants and metal balls as reference objects

“…34 Accurate bone height evaluation above the mandibular canal is essential when planning a posterior implant as insertion of an inadequately long implant can injure the inferior alveolar nerve resulting in permanent hypoesthesia of the lower lip. Machtei et al 35 measured the distance from the apex of a pilot drill to the roof of the inferior alveolar canal on a digital panoramic radiograph (Planmeca Proline XC; Planmeca, Helsinki, Finland; mean 5.18 ± 0.61 mm) and compared it with the readings of an ultrasonic device used to measure the distance from the bottom of the osteotome preparation to the canal (mean 5.26 ± 0.61). They found a strong and highly significant correlation between the two measurement methods, indicating that digital panoramic radiographs have the measurement precision and accuracy required to determine pre-operative implant length for use in the posterior mandible.…”

Intraoperative Measurement of the Distance from the Bottom of Osteotomy to the Mandibular Canal Using a Novel Ultrasonic Device

“…Our results indicated a strong positive correlation between US and radiographic measurements in the mandible; nevertheless, a nonsignificant and weak correlation was found in the maxilla. Based on these results, we have concluded that the tested US device may serve as a useful intraoperative tool to measure the distance from osteotomy to the mandibular canal . Therefore, the aim of the current, prospective clinical trial was to validate our previous results in a larger group of osteotomies in the posterior mandible.…”

“…However, when we dichotomized the results into maxilla and mandible, we found a strong positive correlation between radiographic and US measurements in the mandible, but a weak and nonsignificant correlation in the maxilla. We assumed that these results could be related to difficulties in identifying the floor of the maxillary sinus on panoramic views . Therefore, in the present study we measured only mandibular osteotomies.…”
