Workshop Abstract:

Stepwise Treatment of Acute and Chronic Alveolar Ridge Defects

There is an increasing need from patients for aesthetic fixed dental restorations with, or without implant placement. The alveolar jaw is a tooth dependent structure – any tooth extraction results in alveolar ridge resorption. Surgical techniques used today to preserve or augment deficient ridges follow biologic principles to achieve the same goal: a maintained or enlarged alveolar ridge with harmonious soft tissue contours. While the extent and pattern of resorption varies among individuals, there is an obvious loss of ridge contour as a result of physiological bone remodeling after tooth extraction. The tendency for advanced resorption is even more increased around deep periodontal defects, especially when the buccal alveolar plate has been destroyed. In advanced cases of acute alveolar ridge defects (extraction defects; EDS Class 3, EDS Class 4), alveolar ridge preservation has to be performed in order to reduce or completely avoid the need for further hard tissue reconstructions. However, in some cases horizontal and/or vertical ridge augmentation is inevitable. Therefore, a stepwise surgical protocol has to be implemented to achieve a functionally and esthetically good result.

The lecture will present surgical approaches to reconstruct lost alveolar hard– and soft tissues by applying 3D customized allograft blocks, socket preservation, guided bone regeneration and vestibuloplasty techniques utilising pericardium membrane and PTFE membranes in combination with connective tissue grafts or xenograft 3D soft tissue matrix.
