Abstract
This study was designed to evaluate the use of Periotest device for the assessment of dental implants stability and to correlate its values to the clinical and
radiographic evaluation of success or failure of dental implants. Also the study aimed to detect the factors that may influence Periotest values as coating, diameter, length, design and location of the implant.
Thirty partially edentulous patients who showed motivation towards dental implants were selected as candidates for this study, due to the benefits of implants in
comparison to conventional fixed dental prostheses. They were medically fit for minor oral surgery; to avoid life threatening complications, complicated healing process
and/or rapid marginal bone loss.
Patients were divided into 3 equal groups, each group received 10 implants of only one system; one implant for one patient. Three implant systems were used in
this study namely; ITI, Dyna and Pitt-Easy implant systems. Implants were inserted in
the posterior or anterior region of either jaw with sufficient bone quantity to avoid the
need of ridge augmentation.
Implantation procedures were done in a careful, precise and the least atruamatic manner; for proper preparation of implant beds, to avoid injury of vital structures, complicated healing, to obtain primary stability and to reach osseointegration.
Pre-surgical radiographs were taken to evaluate bone quality and quantity of future implant sites, their relation to vital structures and to detect any bone radiopathy that
may contraindicate implant insertion, while periodic post-operative radiographs were taken to detect the condition of peri-implant bone and to follow up the marginal bone
height.
