Exploration of the Utility of Dental-dedicated MRI for Dentistry

This description observational research is comparative in design, that is comparing existing standard clinical dental images, not obtained in this study, to test (i.e., ddMRI) images. The standard clinical dental images consist of radiographs, such as bitewings, periapical, panoramic, cone-beam CT, and medical CT, as well medical MRIs of the temporomandibular joints (TMJ).The conceptualization of research questions, study designing, and interpretation of imaging data has and will involve content expertise in all ddMRI research.

Effects of Implant Placement Depth (4 mm Versus 6 mm) on Crestal Bone Stability in Immediate Implant Placement: A Clinical Study With 1-Year Post-Restorative Results

The aim of a study was to analyze the effect of implant placement depth (4 mm versus 6 mm below the mid-facial gingival margin) on marginal bone loss (MBL) around implant and implant stability during immediate implant placement after tooth extraction. Clinical trial was conducted involving 35 patients requiring immediate implant placement after tooth extraction. Implants were placed either 4 mm (control group) or 6 mm (test group) below the mid-facial gingival margin. Primary outcome was deemed to be radiographic assessment of marginal bone level from periapical radiographs. Secondary outcome was implant stability quotient registration using resonance freaquency analyzer. The null hypothesis is that there is no significant difference in peri-implant marginal bone loss between implants placed at 4 mm depth versus 6 mm depth relative to the buccal gingival margin during immediate implant placement.
