About

Approximately 40 implants from patients seeking treatment at the University of Oklahoma, College of Dentistry will be recruited for this study. Osteotomies will be prepared using the osseodensification technique and implants will be placed immediately after. The implants will be from a single manufacturer (Roxolid® SLA® Bone Level Tapered; Straumann®, Institut Straumann AG, Basel, Switzerland). Volumetric analysis of alveolar ridge will be studied using intra-surgical direct measurements and CBCT imaging. A custom stent will be fabricated to standardize the clinical and radiographic measurements at 2mm, 3mm, and 4mm apical to the alveolar crest. Changes in peri-implant bone density will be analyzed on standardized periapical and bitewing radiographs, using the ImageJ software (National Institute of Health, Bethesda, Maryland, USA). Implant stability quotient (ISQ) values will be recorded with a resonance frequency analysis system (Osstell®, Gothenburg, Sweden). Calibrated examiners will assess implant survival and biological or restorative complications and failures. Sites will be evaluated throughout osseointegration and one year after final restoration is delivered.
