Novel simplified surgical procedures for lateral bone augmentation
Recently, a simplified bone augmentation procedure, namely the Sub-periosteal Peri-implant Augmented Layer (SPAL) technique, based on the use of the periosteum as a barrier membrane and a particulate deproteinized bovine bone mineral (DBBM) graft as space-making “device” for bone augmentation concomitant to implant placement, has been described (Trombelli et al. 2018) Previous studies showed a complete dehiscence correction rate of 80% associated with a peri-implant buccal bone plate (PBBP) thickness of 3 mm was observed (Trombelli et al. 2019). Moreover, promising results in PBBP thickness augmentation were observed when the SPAL technique was performed in combination with a block of deproteinized bovine bone mineral (bDBBM) (Trombelli et al. 2021). A recent analysis evaluated peri-implant tissue conditions at implants placed in either a deficient PBBP (i.e. a BD or a PBBP thickness <1 mm), corrected by the SPAL technique, or in an adequate (≥ 2 mm) PBBP (Trombelli et al. 2020). Details of the surgical procedures, indications for use and suitable regenerative materials will be thoroughly described.
