Computer Guided Modified Ridge Splitting Versus Free Hand Technique in Horizontal Deficiency in Posterior Mandible

To assess the accuracy of the computer assessed guides in horizontal bone augmentation achieved at posterior mandible using guided modified ridge splitting technique versus free hand modified ridge splitting technique

Implant Phenotype Modification Via GBR and ADM

Single implant sites with bone loss can often be managed by bone grafting alone. The purpose of this study is to determine whether putting a soft tissue graft substitute over the bone graft will provide an increased benefit for improving the health, appearance, and stability of the bone and gums surrounding the implant.

Evaluation of Horizontal Bone Gain of Ridge Augmentation Using Customized Porous Zirconia Shell.

Khoury technique, which employs autogenous bone blocks harvested from the patient, has been widely used for horizontal and vertical ridge augmentation. This method introduces critical limitations, including the technical complexity, morbidity associated with donor site harvesting, such as infection, neurosensory disturbances, and post-operative discomfort This clinical case series aims to demonstrate how customized pours zirconium shell could be an alternative technique for ridge augmentation to overcome the limitations of Khoury shell technique.

Radiographic Assessment of Guided Cortical Shell Technique for Horizontal Ridge Augmentation

The protocol outlines a randomized clinical trial comparing two surgical techniques for horizontal ridge augmentation in the anterior mandible: Computer-Guided Autogenous Cortical Shell Technique (using a patient-specific guide for precise placement). Free-Hand Autogenous Cortical Shell Technique (traditional approach without a guiding template). Key Points: The study aims to determine which method provides better accuracy and bone volume stability. Cone Beam CT scans (CBCT) will assess horizontal bone gain preoperatively and six months postoperatively. The trial is conducted at Cairo University's Faculty of Dentistry. Participants: Patients with pure horizontal bone loss in the anterior mandible. Outcomes: Primary: Bone width gain in millimeters. Secondary: Accuracy of augmentation and surgical time. Methodology: The study group will use computer-designed surgical osteotomy guides to harvest and place bone grafts with improved precision. The control group will rely on the conventional free-hand approach. Both groups will undergo bone grafting using autogenous cortical bone shells. Data Collection \& Analysis: Participants will be randomized and blinded. Data will be analyzed using statistical methods to compare effectiveness.

Tenting Screws Versus Autogenous Ring Block Grafts 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

Evaluation of Bone Regenerated With Guided Bone Regeneration (GBR) Using Polymethylmethacrylate (PMMA) Membrane

To evaluate the quantity and quality of bone generated, radiographically and histomorphometrically, after guided bone regeneration (GBR) using a membrane of 3D printed custom made (PMMA) and subsequent stability of delayed implant placement.

Ridge Splitting Using Autogenous Bone Wedge Versus the Conventional Intercortical Augmentation Technique in Horizontally Deficient Anterior Maxilla

The current study aimed to evaluate both the quality and quantity of gained and maintained bone width after ridge splitting utilizing autogenic bone wedges versus mixed bone particles for horizontal ridge augmentation in the anterior esthetic zone.
