Abstract EN

Background &Objective: Maxillary sinus membrane perforation is the most common complication that occurred with sinus lift.

Various treatment modalities of sinus perforations were proposed.

Platelet-rich fibrin contains many growth factors which have an essential role in wounds healing and tissue regeneration.

The aim of this study was to assess the efficacy of platelet-rich fibrin membrane in management of sinus membrane perforation during sinus lift with simultaneous implant placement.

Methods & Material: Between the years 2010 and 2014, 14 perforations of the sinus membrane smaller than 5 mm were observed during the procedure of maxillary sinus augmentations through lateral approach and simultaneous placement of dental implants.

14 systemically healthy patients (9 males and 5 females) with a mean age of 49.7 years (range, 37 to 59 years) participated in the study.

The sinus membrane is then carefully elevated and covered with platelet-rich fibrin membrane .

Twenty-three Osstem dental implants with a tall of 11,5 - 13 mm and a diameter of 4 mm – 5 mm were installed into the residual bone.

After a healing period of 6 months, abutment connection was performed , and the implants tested clinically in all patients.

Results: Patients tolerated the procedure well.

One infection occurred and resolved after placement of the patient on an appropriate antibiotic for 8 days giving success rate of 92,9% for sinus lift.

Of 23 dental implants placed in the augmented sinuses, one implant was lost during the initial healing period giving an implant survival rate of 95,7% .

Conclusion: Platelet-rich fibrin is a simple and inexpensive biomaterial, and its use as a membrane is a relevant option for management of sinus membrane perforation during sinus lift with simultaneous implant placement
