title: Immediate provisionalization of dental implants in grafted alveolar ridges in the esthetic zone: a 5-year evaluation.
abstract: This clinical study assessed at 5 years both implant survival and peri-implant tissue architecture of immediately provisionalized implants placed 4 to 6 months following augmentation with demineralized bovine bone allograft and collagen membrane. Of 23 implants in 19 patients, one implant failed prior to loading (95.6% survival). Implant tissue relationships were stable following implant placement; marginal bone level changes from implant placement to 5 years (mean ± SD: -0.18 ± 0.79 mm, range: -1.6 to 1.4 mm, P = .51), the mesial and distal papilla length changes (mesial mean ± SD: 1.14 ± 0.92 mm, P < .001; distal mean ± SD: 0.74 ± 1.46 mm, P = .04), and the unchanged mucosal zenith location (mean ± SD: 0.24 ± 0.93 mm, P = .15) were recorded. There were no major surgical complications during the 5-year period. When augmentation is required, subsequent dental implant placement in the anterior maxilla may be achieved using immediate placement and provisionalization protocol to attain osseointegration success and stable peri-implant tissue responses.
