RIDGE SPLIT AND AUGMENTATION TECHNIQUE FOR THE MANAGEMENT OF ATROPHIC MAXILLA: CASE REPORT Atrofik Maksilla Tedavisinde Kret Ayirma ve Ogmentasyon Yöntemi: Olgu Sunumu
2014
ABSTRACT The success of dental implant treatment is being adversely affected by the excess alveolar crest resorption. Many techniques including bone augmentation, guided bone regeneration, ridge split and alveolar distraction techniques have been implemented successfully to overcome this problem. Ridge split technique is based on separation of the buccal and palatal cortical bone into two separate cortical plates in the horizontal plane and augmenting in between using various bone substitutes or placing implants directly. The main advantage of this technique is that it allows the augmenting bone horizontally while preserving the buccal cortical plate. In this case report, the treatment of maxillary horizontal ridge deficiency in edentulous patient was described in steps using piezosurgery, mini-distractors and xenogenic bone substitute. Fixed prosthetic restorations were delivered at the implant placement surgery based on immediate loading protocol. Keywords: Ridge split, maxillary alveolar distraction, mini-distractor, piezosurgery, dental implant OZ Dental implant tedavisinin ba sarisi alveolar kretin a siri rezorpsiyonlardan olumsuz etkilenir. Kemik greftleme yontemleri, yonlendirilmis kemik rejenerasyonu, kret ayirma ve alveoler distraksiyon teknikleri bu problemin cozumu icin basariyla uygulanmaktadir. Kret ayirma-genisletme yontemi, bukkal ve palatal kemik kortekslerini horizontal yonde iki kortikal laminaya ayirarak (ridge split) inley tarzda cesitli kemik greftleri veya dogrudan implant yerlestirilmesi esasina dayanir. Teknigin en onemli avantaji, bukkal kortikal tabakanin korunarak, kemigi horizontal yonde genisletmeye izin vermesidir. Bu olgu sunumunda, ust cenesi total dissiz olan hastada, maksiller alveoler kretin horizontal yondeki yetersizliginin piezocerrahi aygit, mini-ekspandir ve ksenojenik kemik grefti kullanarak rehabilitasyonu basamaklar halinde anlatilmistir. Cerrahi girisimler ile ayni seansta yerlestirilen implantlar hemen yukleme prensipleri uyarinca yuklenerek sabit protetik restorasyonlari tamamlanmistir. Anahtar kelimeler: Kret ayirma, maksilla alveoler ekspansiyon, mini-ekspandir, piezocerrahi, dental implant
