Brief Summary

this study aimed to evaluate both clinically and radiographically the effect of flapless versus flap techniques on initial crestal bone loss and osseointegration of dental implants in lower posterior area. the study is to designed to observe the clinical outcomes such as primary stability and pain within initial hours and days and secondary stability over a 6 month period .

Conditions

Posterior Mandible Missing Tooth and /or Teeth

Keywords

flap and flapless dental implant insertion techniques

Outcome Measures

Primary Outcomes (1)

• crestal bone loss and osseointegration

  initial crestal bone loss around the dental implants measured radiographically and secondary stability checked after six months to check osseointegration of the dental implants by resonance frequency analysis device.

  6 months postoperatively
