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

Author(s):

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.

Socket Gafting with the use of Autologous Bone - an Experimental Study in the Dog
In five beagle dogs, the distal roots of the third and fourth mandibular premolars were removed. The sockets in the right or the left jaw quadrant were grafted with either anorganic bovine bone or with chips of autologous bone harvested from the buccal bone plate. After 3 months of healing, biopsies of the experimental sites were sampled, prepared for buccal–lingual ground sections and examined with respect to size and composition.

Periosteal Pocket Flap for Horizontal Bone Regeneration: A Case Series

Periosteal Pocket Flap for Horizontal Bone Regeneration: A Case Series
This article describes a buccal periosteal pocket flap proposed to overcome these challenges. The flap design results in a periosteal pocket, which allows filling of bone-grafting material while facilitating primary, tension-free soft tissue closure by splitting of the mucosa. The flap gives stability to the augmented volume within the pocket. Ridge width changes of five patients consecutively treated with this technique were recorded before and 24 weeks after augmentation.

Tissue Engineering and Platelet Derived Growth Factors: Evidence Based Therapy
Platelet derived growth factors are now routinely utilized in reconstructive therapy. This presentation describes very detailed and evidence based guidelines for clinicians interested in enhancing their abilities in tissue engineering, especially as it relates to bone augmentation. Specifically, while successful bone augmentation requires the standard surgical parameters of space maintenance, low pressure on the grafts and tension-free flap closure, optimization of this goal requires management and enhancement of the local biological conditions with growth factors. Towards that end, platelet concentrates through the constant release of growth factors are able to promote and enhance new vascularization, provide plasma protein, normal lipidemia, as well as increased collagen and fibrin activity.

Growth Factors; The Next Step in Achieving Ideal Regeneration
The aim of dentistry is to provide esthetics and function for our patients. Using hard and soft tissue regeneration techniques we have the ability to rebuild what has been lost to disease or trauma. Whether we are regenerating lost tissue around teeth or developing an ideal implant site, growth factors are a powerful asset that help make regenerative procedures more predictable while reducing patient morbidity. This webinar review regeneration techniques and will discuss the popular growth factors available today and demonstrate their clinical use.

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 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.
