Details and patient eligibility

About

Teeth loss in the posterior mandible initiates residual ridge resorption especially in vertical direction, this causes difficulty in implant placement so ridge augmentation must be done either simultaneous with implant placement or in a staged approach Aim: To evaluate the effect of bone ring technique versus split bone block technique with simultaneous implant clinically on primary and secondary
