Autogenous Bone Ring Versus Split Bone Block for Management of Posterior Atrophic Mandible

Autogenous Bone Ring Versus Split Bone Block With Simultaneous Implant Placement for Management of Posterior Atrophic Mandible (A Randomized Clinical Trial)

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

Inclusion Criteria:

• Patients with missing posterior mandibular teeth.
• Vertical bone defect from 3 to 4 mm.
• Adequate zone of keratinized tissue.

Exclusion Criteria:

• Presence of infection or periapical lesions in adjacent teeth.
• Medically compromised patients with a condition that affects the procedure.
• Insufficient inter-arch distance.
• Bruxism or clenching.
• Alcoholism.
• Heavy Smokers.
