Maxillary posterior region have often presented challenges for successful dental
implant therapies due to poor bone quality and large sinus cavity resulting in
reduced vertical bone volume.
Variations of sinus lift procedure techniques utilizing osteotome and lateral win-
dow openings have been developed by many clinicians to overcome such
challenges. However, literature reports that many complications such as
perforation of Schneiderian membrane, obstruction of anteronasal foramen,
oronasal fistula formation,infection of the sinus and grafted material, loss of
grafted material, severe haemorrhaging, damage to adjacent dentition, and poor
wound healing, etc., can arise from sinus lift procedures.
Such complications point to inherent difficulties in performing sinus lift
procedures, often even for the most experienced clinicians. |

Thi s prospective study involved 87
implants placed between January 2006 and
December 2007.
There were 65 patients between the age of
19 to 75, and all 87 implants were placed
simultaneously while sinus lift procedure
was performed in the affected region
utilizing a new surgical technique called
Hatch Reamer System. |

 |
No sinus membrane perforation was
observed during the procedure and during
post operative follow-up periods.
Both clinical and radiographic evaluations
were made for each patient.
Early results show 2 implant failures due to
mobility of implants, resulting in 97.7%
success rate so far for the implants placed
utilizing this new sinus lift method. |
