Mandibular Block Autografts for Alveolar Ridge Augmentation Mandibular Block Autografts for Alveolar Ridge Augmentation

Summary:

Reconstruction of alveolar ridge deficiencies requires bone augmentation before implant placement. Osseous defects occur as a result of trauma, prolonged edentulism, congenital anomalies, periodontal disease, and infection, and they often require hard and soft tissue reconstruction. Autogenous bone grafts have been used for many years for ridge augmentation and are still considered the gold standard for jaw reconstruction. The use of autogenous bone grafts with osseointegrated implants originally was discussed by Bra°nemark and colleagues, who often used the iliac crest as the donor site. Other external donor sites include calvarium, rib, and tibia. For repair of most localized alveolar defects, however, block bone grafts from the symphysis and ramus buccal shelf offer advantages over iliac crest grafts, including close proximity of donor and recipient sites, convenient surgical access, decreased donor site morbidity, and decreased cost.

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.

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.

Bioengineering and Bone Grafting in Deficient Anterior Sites: A Case Presentation
Dr. Pikos shares a case presentation elucidating the need for bioengineering and osseous grafting to overcome severe deficiencies in anterior sites prior to implant placement. The case is that of a 19 year old caucasian female that presented with congenitally missing maxillary lateral incisors. Both sites were deficient in alveolar width. Subsequent treatment included a single ramus buccal shelf block bone graft that was utilized for bony augmentation along with mineralized allograft and PRGF with collagen membrane. This was followed 4 months later by two 3.8 mm diameter BioHorizons tapered internal Laser-Lok implants. Four year follow up is included.

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.

BMP, PRP, PRGF and PRF; At the Edge of Regenerative Surgery
Biological modifiers and growth factors are substances that the body produces naturally in response to injury or disease. The use of these substances in regenerative procedures has made hard and soft tissue regeneration more predictable while accelerating healing and decreasing patient morbidity. This webinar will review the wound healing process and the role that growth factors play in regeneration. BMP, PRP, PRF and PRGF will be reviewed and their clinical applications will be demonstrated. At the end of this webinar the participant will have a good understanding of the differences between these biological modifiers and their benefits.
