In 21 patients, 28 maxillary teeth were extracted because of periapical or
periodontal infection, root fracture, or untreatable caries. A rotated pala
tal flap procedure was used to achieve primary soft tissue closure over ext
raction sites. At 5 to 7 weeks postextraction, 28 implants were placed, Buc
cal dehiscence-type defects were treated with guided bone regeneration proc
edures using bovine bone mineral and resorbable collagen membranes. Mean de
fect area at the time of implant placement (23.7 mm(2), SD 11.49) was signi
ficantly reduced at uncovering (0.7 mm(2), SD 0.99). The mean percentage of
defect reduction (clinical bone fill) was 97% (SD 4.26). Implants placed i
n compromised sites shortly postextraction according to the presented 2-sta
ge protocol gave good short-term clinical results.
