Abstract
To evaluate survival rate and bone response around immediate loaded Morse taper implants installed in fresh sockets on the anterior area of the maxilla. The sample comprised 16 patients in whom 16 single implants were installed. All the teeth were extracted in a flapless surgery. Radiographic and tomographic evaluations were performed immediately after surgery (T1) and after 12 months (T2). The variables studied were height of the buccal wall (HBW), buccal wall width (BW) at 3 levels, and proximal bone height at 2 different areas: the alveolar crest level (CLH) and at the point where bone tissue meets the implant surface (BIS). Statistically significant differences were observed. The buccal plate showed bone loss in height (HBW = -0.50 ± 0.42 mm) and in width (BW-1 = -0.71 ± 0.48 mm; BW-2 = -0.48 ± 0.34 mm; BW-3 = -0.48 ± 0.34 mm). In the proximal areas, there was also bone loss in height (CLH-M = -0.85 ± 0.89 mm; BIS-M = -0.91 ± 0.70 mm; CLH-D = -0.64 ± 0.57 mm; and BIS-D = -0.68 ± 0.62 mm). There was 100% survival rate after a 12-month period, but bone loss was observed in all evaluated areas.
