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)

• Status: Completed
• Phase: N/A
• Study type: Interventional
• Enrollment: 16 (actual)
• Sponsor: Alexandria University · Academic / Other
• Sex: All
• Age: 35 Years – 50 Years
• Healthy volunteers: Not accepted

Summary

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

Conditions

• Ridge Augmentation

Interventions

Type	Name	Description
OTHER	Bone Ring	Patients in this group will be treated with the bone ring technique. An implant drill will be used next to prepare central osteotomies corresponding to the final implant diameter to be placed in the center of the disc converting it to a "bone ring".
OTHER	Split Bone block	Patients of this group will be treated with split bone block with simultaneous implant technique. The bone shell will be split into two bone shells each 1 \~ 2 mm in thickness using a disc.
