Background: A number of complications can occur during sinus augmentation surgery and zygomatic implants surgery. These complications sometimes represent for the surgeon a very difficult management and treatment.

Aim: The aim of this presentation is to demonstrate clinically how to treat and prevent complication in complex implant surgery.

Materials and methods: The patients were divided in two groups. Group A the patients were submitted to zygomatic implants (ZI) surgery and Group B patients submitted to sinus augmentation. The BFP flap technique was used in all patients to treat and prevent complications. In the Group A the technique was used to prevent thread implants exposure by mucosa fenestration or to closure of oroantral communications promoted by loss of sinus walls. In the Group B, to protect grafted materials in sinus augmentation with large perforation of Schneiderian membrane.

Results: Between May 2005 to July 2009 a total of 17 patients, 4 females and 13 males with mean age of 56 years were submitted to complex implants surgeries. In Group A ( n = 9) the total of 17 zygomatic implants were covered by BFP pedicled flap implants and in four sinuses the technique was used to closure of oroantral communications associated to ZI. In Group B ( n = 8) 13 sinuses presented large membrane perforation and the BFPF technique was used to protect grafted materials and implants. The patients were followed-up in a minimum period of 12 months.

Conclusions and clinical implications: The BFP pedicled flap technique demonstrated success in advanced and complex implant surgeries.
