Mandibular Block Autografts for Alveolar Ridge Augmentation
Michael A Pikos, DDS
This article reviews indications, limitations, presurgical evaluation, surgical protocol, and complications associated with mandibular block autografts harvested from the symphysis and ramus buccal shelf for alveolar ridge augmentation. The author draws from 14 years of experience with more than 500 mandibular block autografts.
Intraoral Autogenous Block Onlay Bone Grafting for ExtensiveReconstruction of Atrophic Maxillary Alveolar Ridges
Autologous bone grafting used with dental implants was originally described by Bränemarketal in 1975, and is now a well-accepted procedure in oral and maxillofacial rehabilitation.Placement of an endosseous implant requires sufficient bone volume for complete bone coverage. Furthermore, the pattern of ridge resorption contributes to an unfavorable maxillomandibular relationship, requires angulations of the implants and/or angled abutments, and affects the proximity of adjacent facial concavities(maxillary sinus, nasal cavity) and vital structures(mandibular nerve).
The safety of bone allografts used in dentistry
Recent media reports concerning “stolen body parts”
have shaken the public’s trust in the safety of and the use of ethical practices involving human allografts. The authors provide a comprehensive review of the safety aspects of human bone allografts.
Alloplastic Bone Substitutes Around Dental Implants
The repair of osseous defects has been a goal in dentistry for many decades. Subsequently, within the last several years, there has been an emergence of a new class of materials in dentistry referred to as synthetic bone. Finding the ideal bone substitute material has been the goal of researchers for many years. In attempting to achieve this ideal material, dental practitioners have tried with varying degrees of success: autogenous and demineralized freeze-dried bone, allografts of plastic, carbon…
Gaining Horizontal and Vertical Bone with Mineralized Bone Particulate, rh-BMP2 and Resorbable Ultrasonic-Applied Rigid Barriers
The use of titanium mesh has been well described, but so has the complications of removal and exposure. Bioresorbable barriers are now available which can be molded into any desired three-dimensional form, creating a rigid and resorbable construct that is secured to the bone using ultrasonic energy. This unique solution has been successfully used to create the proper environment for both large lateral and vertical ridge augmentations for situations previously only treated with block grafting or distraction. Dr. Cummings will share his experience as well as the key soft tissue techniques that are critical for the success of any large augmentation.

Titanium Mesh and rhBMP-2 in Ridge Augmentation: Options and Limitations
Titanium mesh has been used in reconstructive surgery and ridge augmentation for several years. The traditional technique involves using cancellous autogenous bone under the mesh scaffold. More recently growth factors and bone substitutes have been utilized as autograft replacements. There are several advantages to using titanium mesh for space maintenance including strength, ease of use, low cost and biocompatibility. However, the difficulty in removing the mesh has led to a search for other space maintenance scaffolds including tenting screws, dense preshaped collagen and porous high-density polyethylene. This webinar will discuss the use of rhBMP-2 for managing horizontal and vertical bone deficiencies with various scaffolds.
Bone Graft Solutions in the Treatment of a Defective & Deficient Ridges; Advantages of Combined Therapy
More patients are treated with implants than ever before. Unfortunately, many have insufficient bone available to support an implant prosthesis. This presentation describes the utilization of several different augmentation approaches for the severely resorbed ridge and dentally handicapped fully endentulous patient. Current concepts related to autogenous bone harvest, 3D bone augmentation combined with blood born bioactive modifiers and digital planning are defined. Video and high resolution images are utilized to further describe these approaches.
