In this webinar, the use of mucoderm® in peri-implant augmentation will be discussed, highlighting its properties and advantages in the aesthetic zone.
Dimensional and structural alterations of the alveolar process are well-documented consequences of tooth extraction in the aesthetic zone, with several factors influencing bone modelling, such as flapless extractions, ridge preservation techniques and immediate implant placement.
Over the years, several authors have investigated bone resorption pattern in maxillary incisors and premolars, concluding that a facial bone wall thickness of 1 mm or less was the main factor affecting the degree of bone alterations.
Furthermore, soft tissue alterations may follow tooth extraction, in particular loss of keratinized mucosa width (KMW), with a significant impact on the aesthetic and functional outcomes of future implant-supported restorations. The optimal timing for implant placement and the necessity of alveolar ridge preservation procedures are still debated in literature. A simultaneous or subsequent connective tissue graft (CTG) may be needed in order to prevent/treat mucosal recession.
Over the years, several bone substitutes have been utilized for GBR procedures and, recently, a porcine derived acellular dermal matrix (mucoderm®) has been proposed as autogenous graft substitute in order to avoid palatal harvesting and obtain comparable results to CTGs, with excellent dimensional stability and aesthetic results.
