Abstract

Objectives: posterior maxillary region exhibits low bone density that affects implant
stability placed using conventional drilling protocol. The present study aimed to assess implant
stability and bone density of densah bur osseodensification drilling in maxillary posterior region..
Patients and Methods: sixteen implants were inserted for 8 patients aged between 32 and 45
years old with posterior maxillary single or multiple missing teeth. Implants were randomly
divided into two equal groups: group (I) (n=8): implant bed was prepared using densah burs,
and group (II) (n=8): implant bed was prepared using conventional drills. The patients were
evaluated clinically and radiographically preoperatively, immediately post-implantation and 6
months postoperatively. Clinical evaluation using Resonance frequency analysis (RFA) for
implant stability. Radiographic evaluation was achieved by CBCT to measure bone density.
Results: for implant stability, there was a statistically significant difference between both groups
in primary and secondary stability. For bone density, there was a statistically significant
difference between both groups in all intervals. Conclusions: using osseodensification protocol
by densah burs improves osteotomy preparation in maxillary alveolar bone with low density,
Densah burs show higher primary implant stability values and improves bone density around
dental implants.
