Comparison Between Ultrasound and Clinical Measurements Clinical Trial
Official title:
The Use of Novel us Device (Jetguide) to Measure the Distance to the Roof of the IAC (Inferior Alveolar Canal)
The purpose of this human clinical trial is to validate the accuracy of Jetguide® US device in detecting the inferior alveolar canal (IAC) and to compare it to measurements performed on computerized tomography images.
To date, the most accurate method to assess the distance from the alveolar crest to the IAC
is cone beam computerized tomography (CBCT). This technique carries with it some potential
concerns, including measurements errors, inability to perform intra-operative radiographs
substantial financial and radiation costs.
In the present study patients will have a CBCT of the mandible taken. Sites where implants
will be inserted will be marked on the CBCT, measurements of the distance from bone crest to
the roof of the inferior alveolar canal (BC-IAC) will be performed.
During implant surgery the depth of the osteotomy (OD) will be measured using a periodontal
probe; OD and the distance from the bottom of the osteotomy to the roof of the IAC (residual
distance - RD) will be measured using a standard JetGuide® device. In addition, standard
panoramic radiographs will be taken with a surgical gauge in the osteotomy which will enable
us to measure the RD radiographically.
The correlation between the radiographic and clinical BC-IAC distance will be the primary
outcome variable. The same correlation for the RD between the Jetguide readings and the
linear measurements on the panoramic radiographs will serve as the secondary outcome
variable.
