Tenting Screws Versus Autogenous Ring Block Grafts During Horizontal Ridge Augmentation

Tenting Screws Combined With Particulate Autogenous and Xenogenic Bone Versus Autogenous Ring Block Grafts Combined With Xenogenic Bone During Horizontal Ridge Augmentation

After administering local anesthesia,. A full-thickness mucoperiosteal flap will be incised and be reflected to expose the alveolar bone. The dimensions of the defect will be measured using a periodontal probe to determine the appropriate size of the block graft or the quantity of particle bone graft required.

In the non screw group, the blocks will be adapted to fit the recipient sites and secured to the alveolar bone using titanium bone fixation screws. Following the placement of the blocks, bovine particles will be applied over the graft and into any remaining gaps between the block and the recipient site, a resorbable collagen membrane (CM) will be shaped and placed over the graft and fixed using subperiosteal sutures.

In Tenting screw cases, the screws will be placed in suitable positions and depths, blocks will be crushed into particulates which will then be mixed with equal amount of bovine particles. the mixture will be applied to the recipient site all around the tenting screws a resorbable collagen membrane (CM) will be shaped and placed over the graft and fixed using subperiosteal sutures.

The flaps will then be sutured
