['This study investigates the pre- and posttreatment morphology of the mucosa around immediately loaded implants in the edentulous maxilla.', 'Implants were placed and immediately loaded in edentulous maxillae; pre- and posttreatment impressions were obtained. The resulting casts were digitalized into 3-dimensional images, and the pre- and posttreatment images were superimposed. The width and height of the maxillary alveolar process were measured at central and interproximal implant sites in a vertical section of the superimposed holograms. For statistical analysis, the Delta value (d) was defined as the difference between the pre- and posttreatment images for all measurements.', 'Sixty-seven Straumann implants placed in 9 patients and immediately restored with provisional fixed restorations were analyzed. An increase in width at all measurement sites was observed after treatment. Width increased for both central implant (1.51 +/- 1.16 mm, P < .001) and interproximal implant sections (1.02 +/- 1.21 mm, P < .001). Mean d for height was found to be decreased at central implant sites (-1.21 +/- 1.67 mm, P = .012) and at interproximal sections (-0.72 +/- 1.68 mm, P = .098).'] Do influence of immediate implant loading on peri-implant soft tissue morphology in the edentulous maxilla?
