Retrospective Evaluation of Crestal Bone Changes Around Implants With Reduced Abutment Diameter Placed Non-Submerged and at Subcrestal Positions: The Effect of Bone Grafting at Implant Placement
One method to measure the success of dental implant treatment is to evaluate marginal peri-implant bone-level changes and stability over time. The location of the fixture–abutment interface (FAI) can be of major importance when the goal is to construct esthetic restorations. In these situations the FAI is often placed in a more apical position to create an ideal emergence profile for the prosthetic construction. However, several animal studies have reported that placement of the FAI in a subcrestal position may result in peri-implant marginal bone loss. The aim of the present study is to evaluate the effect of bone grafting of the defect between the bone crest and the coronal aspect of the implant for implants with reduced abutment diameters placed non-submerged and in subcrestal positions.

Multitier Technique for Bone Augmentation Using Intraoral Autogenous Bone Blocks
Brånemarket al1 originally described autologous bone grafts used with dental implants,and they are now a well-accepted procedure in oral and maxillofacial rehabilitation. Placement of an end osseous implant requires sufficient bone volume for complete bone coverage.Further-more,the patter no fridge resorption ,which contributes to a nun favorable maxillo mandibular relationship,requires angulation of the implant and/or angled abutment,and affects the proximity of adjacent facial concavities (maxillary sinus,nasal cavity)and vital structures(mandibular nerve).

Screw "Tent-Pole" Grafting Technique for Reconstruction of Large Vertical Alveolar Ridge Defects Using Human Mineralized Allograft for Implant Site Preparation
The purpose of this study was to evaluate the effectiveness of using titanium screws in combination with particulate human mineralized allograft, in a “tenting” fashion, to augment large vertical alveolar ridge defects for implant placement.

Alveolar Ridge Regenerative Strategies: Autogenous Bone vs BMP-2
This clinical based presentation will compare the use of autogenous bone vs BMP-2 for alveolar ridge reconstruction. The science, indications, advantages and disadvantages of each approach will be featured. Single tooth to full arch reconstruction cases will also be shown along with understanding the application of non-resorbable vs resorbable mesh barriers for alveolar ridge reconstruction.

Titanium Mesh GBR in Combination with Bioactive Modifiers and Implant Placement
This Surgical Video will highlight the utilization of a new CTi Titanium Mesh product that intimately connects to the top of the implant to create space for Guided Bone Regeneration.

Bone Putties for GBR and Ridge Augmentation: A review for the general practitioner - Part 1 of 2
Dr. Michael Tischler reviews the utilization of bone allografts in putty form for guided bone regeneration, GBR, and ridge augmentation.

CadCam Customized 3D-Printed Subperiosteal Implant
When considering the future of implants, it appears justified to reconsider the old concepts in light of the availability of contemporary technologies, such as computer-aided design, softwares and programs design, virtual stress– strain testing, and 3D printing of titanium alloy. With the employment of these modern technologies, the concept of a “high-tech” subperiosteal implant has gradually emerged. Biological design of subperiosteal implant is mandatory for the success of the treatment, guidelines on architectural changes, topological optimization, and biofunctionalization will be explained. This new era of a “high-tech” customized 3D printed subperiosteal implant leads us to consider this technique s a valuable treatment option for atrophic jaws, avoiding more invasive procedures and giving the possibility of immediate loading, improving the patient’s quality of life.

Fresh Frozen Allograft Bone plus Bone Marrow Aspiration as a NEW Alternative to Autogenous Bone Augmentation - Part 2 of 2
This lecture presentation will describe the behaviour and utilization of of fresh frozen allograft vs. autogenous bone in major bone augmentation cases. The advantages and disadvantages as well as the potential of adding bone marrow aspirate to fresh frozen bone will be further highlighted. In depth review of how to manage and use this new technique in clinical practice will be clearly explained.

Surgical Management of Posterior Maxilla
Replacement of missing teeth with dental Implants in the posterior maxilla presents unique challenges due to maxillary sinus, less quality of bone, and increased occlusal load. The surgical objectives to meet functional and aesthetic goals include enhancement of both quantity and quality of bone as well as ideal placement of dental implants for restorations that mimic nature. In this presentation, Dr. H. Ryan Kazemi discusses current surgical techniques in implant site development in the posterior maxilla including extraction site grafting, sinus lift, bi-directional bone graft, and osseodensification for bone management.
