DOUBLE-LOBED MAXILLARY SINUS LIFT AND DENTAL IMPLANT TREATMENT: A CASE REPORT

Maxillary sinus lifting is one of the most common surgical procedures in the case of inadequate maxillary posterior vertical bone. Maxillary sinus septa can complicate inversion of lateral window and elevation of sinus membrane during the sinus lift surgery. The aim of this case report was to perform correct steps of sinus lift surgery and dental implant application in the presence of maxillary sinus septa. 48 year-old-female patient was admitted to our clinic for implant treatment at left maxillary region. In the radiographic examination, insufficient vertical bone height and double-lobed maxillary sinus were seen. Maxillary sinus lifting procedure was performed separately for both lobes. Formation of sufficient vertical bone height was lasted about 6 months for dental implant application. After this period, dental implant was performed and osseointegration has occurred. Maxillary sinus lifting procedure is a predictable technique to increase bone volume of posterior maxilla and for dental implant placement in the presence of anatomical variations. In the posterior maxilla, anatomical variations like sinus septa should be well known by the surgeon to prevent possible complications during sinus lifting. Key words: dental implant, sinus lifting, osseointegratio CIFT LOBLU MAKSILLER SINUS LIFTING VE DENTAL IMPLANT UYGULAMASI: BIR OLGU SUNUMU OZ Sinus lifting operasyonu maksiller posterior bolgede yetersiz vertikal kemik varliginda uygulanan en yaygin cerrahi operasyon teknigidir. Sinus septa varligi, sinus lifting operasyonu sirasinda lateral pencerenin acilmasi ve sinus membran elevasyonunda komplikasyonlarin olusmasina neden olabilmektedir. Bu olgu sunumunun amaci septa varliginda sinus lifting oprasyonun tum basamaklarinin dogru bir sekilde yapilmasi ve dental implant uygulamasinin basarili olmasidir. 48 yasindaki bayan hasta klinigimize sag ust cene bolgesine implant tedavisi gormek icin basvurdu. Radyografik muayenede ilgili bolgede azalmis kemik yuksekligi ve cift loblu maksiller sinus varligi gozlendi. Her iki maksiller loba ayri ayri sinus lifting islemi yapildi. Sinus lifting isleminden alti ay sonra yeterli kemik yuksekligi saglandiktan sonra dental implantlar yerlestirildi. Dental implantlarin 3 ay sonra yapilan kontrollerinde osseointegrasyonun saglandigi gozlemlendi. Sinus lifting operasyonu anatomik varyasyonlarin varliginda da posterior maksiller kemigin vertikal yuksekligin arttirilmasinda ve implant uygulamasinda kullanilabilir bir yontemdir. Posterior maksiller bolgede sinus septa gibi anatomik varyasyonlarin sinus lifting operayonu sirasinda olusabilecek komplikasyonlari onlemek icin cerrah tarafindan cok iyi bir sekilde bilinmesi gerekmektedir.
