Correlate the implant stability quotient values measured by ostell device with radiographic bone density measured on CBCT by bluesky software pre-operatively

Dental implants have been widely used in the field of dental rehabilitation. Nowadays implant sucess rate is very high but to keep faliure rate as low as possible patient selection is very important especially regarding bone density to achieve high primary stability. Primary stability plays an important role in successful osteointegration of dental implants. This study was done to correlate between the bone density pre operatively measured on CBCT represented by HF unit and implant stability measured post operatively by ostell device represented by ISQ unit

Inclusion Criteria:

• patients receiving dental implants in both arches
• patients should be free from any systemic diseases that may affect normal healing of bone, and predicated outcome
• no intra-oral soft tissue defect that would render primary closure of the intra-oral wound

Exclusion Criteria:

• patients with systemic diseases

  _ patients with ridge augmentation such as ridge expansion, ridge splitting and bone grafting

• patients with sinus lifting done to place implants

• immediate extraction sockets
