Brief Summary

A successful implant surgery primarily relies on a prudent evaluation of oral anatomy and meticulous treatment planning. Additionally, of paramount importance that dictates the types of procedures, material selection and ultimately success of implant surgery is the quality and quantity of the edentulous ridge. Ultrasound imaging (US), another cross-sectional imaging modality, has been extensively used in the medical diagnostics field. The ability of ultrasound to image soft tissue-bone interface makes it particularly promising for studying bone ridge width and crestal bone topography. Therefore, this retrospective human study aimed to compare bone width measurements between US and CBCT. This study also investigated the possible correlation between the crestal bone surface quality imaged by US and CBCT.

Conditions

Ultrasonography

Outcome Measures

Primary Outcomes (1)

• Accuracy of ultrasound for estimating ridge width

  measure the edentulous ridge width at 1, 2 and 3 mm apical to the crest on ultrasound images

  up to 3 months after image was taken

Secondary Outcomes (1)

• Accuracy of ultrasound for assessing ridge surface quality

  up to 3 months after image was taken

Study Arms (1)

Group with edentulous ridge

This group had edentulous ridge planning to receive a dental implant and had ultrasound and cone-beam computed tomography images of the ridge.

Eligibility Criteria

• Sex: all
• Healthy Volunteers: No
• Age Groups: Child (0-17), Adult (18-64), Older Adult (65+)
• Sampling Method: Non-Probability Sample

Study Population

Records of patients who had at least 1 edentulous ridge with a plan for implant placement, had cone-beam computed tomography as standard procedure and ultrasound imaging for off-label use of evaluating the ridge were included.

You may qualify if:

• Patient records at the Graduate Periodontal Clinic
• With both US and CBCT scans taking within 3 months between each other from Jan 2016 to Mar 2020
• These images had to include at least one edentulous ridge at the anterior, premolar or molar site.
• Multiple sites in a given patient may be included.
