A 31-year-old female patient came to the practice, who lost her 2 upper mesial incisors at the age of 12. Crestal bone width was less than 2 mm. A GBR with cerabone®, maxgraft® and Jason® membrane was performed. After a healing time of 5 months, an excellent bone reconstruction was achieved. Two implants (11,21) could be placed successfully in almost 5 mm bone width.
