Recombinant Human Bone Morphogenetic Protein 2 in Lateral Ridge Augmentation

Robert Mehanna, DMD/Samuel Koo, DDS, MS/David M. Kim, DDS, DMSc

DOI: 10.11607/prd.1347

This case report describes the augmentation of severe lateral ridge defects in the maxilla and mandible using recombinant human bone morphogenetic protein 2 (rhBMP-2) on an absorbable collagen sponge (ACS). The surgical technique used tenting screws and a membrane to maintain space for the ACS. After 7 months of healing, the ridge width increased from 1 to 2 mm to 6 to 9 mm, thus allowing successful placement of dental implants. De novo bone formation through use of the surgical technique for space maintenance of rhBMP-2/ACS was demonstrated without the need for additional particulate bone grafting.
