Brief summary
The design is a single blinded, dual comparative study of ultrasound versus micro-CT/LASCA in one study group. Up to a total of 140 subjects registered will be recruited. Subjects who are treatment planned for extraction of a hopeless tooth and socket augmentation with bone graft and are planned for a dental implant surgery. The socket will be evaluated before the extraction and multi-time points during healing until an implant is placed with various evaluation tools, including ultrasound.
Detailed description
The design is a single blinded, dual comparative study of ultrasound versus micro-CT/LASCA in one study group. Up to a total of 140 subjects registered will be recruited. Subjects who are treatment planned for extraction of a hopeless tooth and socket augmentation with bone graft and are planned for a dental implant surgery. Qualified subjects will be asked during their pre-assessment visit. Subjects will be scanned with ultrasound and LASCA among other assessments shown in the info-graph and schedule of events. At the day of tooth extraction and socket augmentation (graft placement), clinical exams/measurements are taken, along with other research activities described in the info-graph and schedule of events. Recovery (checkups) from surgery will be monitored at 2 weeks, 1 month and 2 months, and 3 months. The timepoints additional to normal clinical timepoints are needed to gather potentially diagnostic valuable information about graft maturation, which in the future may lead to an early graft failure decision or trigger other clinical steps such as infection management.

Inclusion criteria
* Patients at least 18 years of age and have at least a tooth that is considered hopeless, planned for an extraction and a bone grafting procedure for subsequent dental implant surgery.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Primary Objective | approximately 6 months | To determine if bone graft maturation can be imaged by ultrasound. Bone healing by ultrasound will be given a scale and will be compared to the reference standard micro-computed tomography (micro-CT) of tissue core biopsy taken at implant surgery |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Secondary Objective | approximately 6 months | To determine if bone graft maturation can be imaged by ultrasound, by comparing to clinical healing appearances. A score will be given to ultrasound image and clinical outcome and the correlation will be evaluated. |
