Efficacy of Different Osseodensification Techniques

Evaluation Of Different Motor Driven Osseodensification Techniques Used For Implant Placement In Posteriorly Atrophied Mandible Of Osteoporotic Patients

different possible osseodensification techniques used to improve bone density around dental implants, using either ] osseodensifying drills, reverse drilling of conventional drills, and rotary expanders.

the study include 3 groups with different implant drilling protocols; group 1 where osseodensifying burs are used, group 2 where conventional drills with reverse motion are used, group 3 where rotary expanders are used

Inclusion Criteria:

• · Adult osteoporotic female patients confirmed by CBCT grey values ranging from 290 to 420 HU, with age range 45-60 years.

  • Patients should be free from any other systemic diseases, according to ASA classifications (American society of Anesthesiologists).
  • Patients of single or multiple missing teeth in the posterior mandible.
  • A ridge width of 4mm and a height of > 8mm above the roof of Inferior Alveolar canal.
  • No buccal concavities were present at the planned implant site

Exclusion Criteria:

• · Poor oral hygiene.

  • Heavy smoker (more than 20 cigarettes /day),or alcoholic abusing patients.
  • Radiation therapy to the head and neck region, or chemotherapy in the last 6 months prior to the implant placement.
