ObjectiveTo study the clinical result of placement of short implants using an osteotome sinus floor elevation technique without bone grafting in the posterior maxillary.MethodsThe short implants (≤8mm) were placed using an osteotome sinus floor elevation procedure in8mm or less of bone height.Group A:Forty-two short implants were placed in30treated patients.Three to six months after implant placement,theendo-sinus bone gain and the marginal bone resorption at the mesial and distal sides were measured.Group B:Seventeen short implants were used to restore12partially endentulous patients with fixed prostheses.The short implants were followed in function for7to27months.ResultsGroup A:All showed endo-sinus bone gain;the mean gain was (2.74±0.91) mm.The mean marginal bone resorption was (0.48±0.36) mm.Endo-sinus bone gain and residual bone height showed a negative correlation (r=-0.335).A strong good correlation (r=0.653) was found between implant penetration in the sinus and endo-sinus bone gain.Group B:All implants were successfully loaded.The cumulative success rates in function were100%.ConclusionsPlacement of short implants using an osteotome sinus floor elevation technique without bone grafting in the posterior maxilla may be a viable clinical intervention with a good short-term clinical outcome.
