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.
Physical And Chemical Properties Of Commercially Available Mineralized Bone Allograft
Bone graft materials are critical to the success of dental
implants when there is a need to increase the volume of bone
in a defect. The surface properties of these graft materials will have a profound impact on the outcome of the graft procedure. The clinician has many choices of bone graft substitutes when augmenting bony deficits. Allograft bone is the most widely used class of bone graft substitutes. Within this class there are a number of different bone allografts, which are manufactured utilizing widely varying processing techniques. There also appears to be a wide range of results in the published literature across the spectrum of different bone allografts.
This in-vitro study evaluated chemical and surface
properties of five different commercially available
mineralized bone allografts.
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.
Long Term Follow-Up of Dental Implants Placed in Autologous Onlay Bone Graft
The aim of this study was to evaluate the efficacy of autologous intraoral onlay bone grafting (OBG) in correlation
with long-term survival rates of dental implants placed in the augmented bone. A retrospective study was conducted on 214 patients who received a total of 633 dental implants
placed in 224 autologous intraoral block OBG augmentations, combined with Bio-Oss – mixed with platelet-rich plasma
(PRP) and covered by platelet-poor plasma (PPP) – as scaffold, with a follow-up time up to 137 months. We suggest that augmentation of severely atrophied jaw bone through the placement of horizontal and/or vertical intraoral OBGs in combination with Bio-Oss saturated with PRP and covered by PPP should be considered a reliable, safe, and very effective surgical technique for obtaining high bone graft survival rate and high long-term implant
Understanding and Prevention of Peri-implant Recession
Dr. Gerd Körner outlines the multi-variable causes that may be responsible for recession around implant restorations.
The Role of Piezo-Surgical Ridge Split Technique in the Reconstruction of Ridge Deficiencies - Part 1 of 2
This 2 part lecture demonstrates the piezoelectric hinge assisted ridge split (PHARS) technique for reconstruction of ridge deficiencies to facilitate the placement of dental implants. A review of multiple ridge augmentation techniques is provided along with advantages and unique challenges of the PHARS technique.
Bone Putties for GBR and Ridge Augmentation: A review for the general practitioner - Part 2 of 2
Dr. Michael Tischler reviews the utilization of bone allografts in putty form for guided bone regeneration, GBR, and ridge augmentation.
Bone Augmentation & Bioengineering in the Clinical Implant Practice
This webinar will introduce efficient and predictable bone graft solutions as well as bioactive modifiers that can be immediately incorporated into clinical practice.
Biologic Strategies to Enhance Clinical and Aesthetic Success in Oral Implantology
This webinar will discuss clinical strategies for treatment of the complex implant site involving bone grafting and implant placement. Our understanding of cellular pathways, and our ability to control the wound response, expands our capacity to effect better aesthetic outcomes and compress treatment time. The reduction of the inflammatory phase of tissue regeneration speeds up osseointegration, prevents crestal bone loss, maintains papillary form, increases the density of peri-implant bone and increases tissue biotype. This enhanced tissue response allows us to predictably treat even the most complex surgical cases, compress time to final reconstruction, and to maintain these favorable tissue outcomes over an extended period of time. The use of dental implants with advanced biologic features and the incorporation autologous growth factors will be demonstrated.
Advanced Bone Grafting Techniques: Part 2 - Autogenous Bone Blocks in the Reconstruction of the Atrophic Maxillary Ridge
This lecture will describe the use of autologous onlay block bone grafting for reconstruction of moderate to severe atrophic maxillary alveolar ridge. This will include a discussion of the various options to this form of grafting, such as short implants, maxillary sinus augmentation, sub-nasal elevation procedure, connective tissue grafting and soft tissue manipulation, Le-Fort I down fracture/osteotomy and the use of progenitor cells: bone marrow aspirating concentrated. The Mutli-Tier onlay Bone Graft Technique will be highlighted in this presentation. Additionally, a review of a recently submitted research paper of long term follow up of implants placed into autologous bone blocks harvested from the mandibular ramus, immediate loading by pre-computer-aided/pre-prepared temporary bridge areas will be discussed.
