Book excerpt: Aim: To assess the performance of microtextured dental implants with or without a machined collar at one year after placement. Material and Methods: Fifty-eight patients received dental implant therapy to restore missing teeth in one area of the maxilla or mandible at the UAB Department of Graduate Periodontology. Residents in the program placed microtextured implants with a microtextured collar with microgrooves (test group) and microtextured implants with a machined collar (control group). Sites were randomized to the test group or control group. Study visit protocol was followed and implants were restored by off-site dentists. Sixty-nine (69) implants were assessed at one year for a final study visit. The primary outcome was to determine the difference between crestal bone levels in the test versus the control group implants as measured by differences in radiographic crestal bone heights at baseline and one year. Data collected consisted of periapical radiographs and clinical photographs that were taken at specific time points throughout the study period. Statistical analyses using individual t-tests and ANOVA were performed to analyze the data. Results: Statistical analysis determined that a significant difference in marginal bone loss was present between the roughened collar (0.65±0.43) and machined collar (1.20±0.62) MTX implants at one year (p
