Summary:
There is a number of augmentation techniques, such as the use of different kinds of bone grafts, Guided Bone Regeneration (GBR), sinus lift surgery, osteotomy techniques (Sandwich and bone split technique), distraction osteogenesis and combination of the above.
The purpose of this review is to study the technique of Alveolar Distraction Osteogenesis (ADO) and compare it to other augmentation techniques of the alveolar ridge, discovering its possibilities as a surgical choice for the augmentation of the alveolar ridge before implant placement.
There is a big variety of ADO devices, designed for each case, defect size and augmentation goal. An important advantage of the ADO technique is the simultaneous distraction of the soft tissues, eliminating the need to provide an adequate amount of ceratinized tissue.
Comparing the ridge augmentation techniques, the advantages and disadvantages of each one, as well as their indications, need to be taken into consideration. Distraction osteogenesis is a better choice when there is need for extensive augmentation of ridge height. Moreover the waiting period for implant placement is shorter. However specific dimensions of native bone are required for the osteotomies to be performed and the components of the device to be born, which combined with the high cost of the technique, leads the clinician towards other simpler and cheaper solutions.
In conclusion the clinician’s goal is not the choice of a standardized technique among the various ones, but the provision of the best possible result, for each case individually.
