This study assessed the efficacy of augmentation grafting of the maxillary
sinus with simultaneous placement of dental implants in patients with less
than 5 mm of alveolar crestal bone height in the posterior maxilla prior to
grafting, although the procedure has traditionally been contraindicated ba
sed on empirical data. A total of 160 hydroxyapatite-coated implants was pl
aced into 63 grafted maxillary sinuses in 63 patients whose crestal bone he
ight in this region ranged from 3 to 5 mm. Patients were followed for 2 to
4 years after the placement of definitive prostheses. There were no postope
rative sinus complications. Following uncovering of the implants at 9 month
s after surgery, there was no clinical or radiographic evidence of crestal
bone loss around the implants. Histologic examination of bone cores from th
e grafted sites revealed successful integration and a high degree of cellul
arity. All patients maintained stable implant prostheses during follow-up.
These findings indicate that the single-step procedure is a feasible option
for patients with as little as 3 mm of alveolar bone height prior to augme
ntation grafting, utilizing hydroxyapatite-coated implants and autogenous b
one.
