Abstract

Oligodonti; süt, kalıcı veya her iki dentisyonda
altıdan fazla dişin konjenital eksikliği ile
karakterize, nadir bir genetik hastalıktır. Genellikle
bir sendromun parçasıdır, ancak nadiren izole
olarak ortaya çıkabilir. Oligodonti hastalarında
dişlerin hiç oluşmamasına paralel olarak genellikle
alveolar kretlerde de ciddi atrofiler mevcut
olmaktadır. Dolayısıyla bu hastaların protetik
rehabilitasyonları da klinisyenler için oldukça güç
olabilmektedir. All-on-4 tedavi konsepti, anterior
bölgeye iki adet dik ve posterior bölgeye iki adet
eğimli yerleştirilen, toplam dört implant destekli,
tek parça, tüm ark protez uygulamasını içeren,
tam dişsiz çenelerin sabit protetik rehebilitasyonu
için uygulanan bir tedavi metodudur. Yapılan
çalışmalarda, posterior bölgeye eğimli yerleştirilen
implantların ileri cerrahi işlemlere gerek kalmadan,
anatomik sınırlamalara takılmadan uygulanabildiği,
biyomekanik kuvvetleri daha iyi karşıladığı,
protetik kantilever uzantıların boyutunu azalmasını
sağladığı ve ayrıca başarısızlık oranlarında dik
yerleştirilen implantlarla karşılaştırıldığında
anlamlı bir fark bulunmadığı bildirilmektedir.
Bu olgu sunumunda, maksillada sadece üç dişi
ve mandibulada sadece ön grup dişleri olan 22
yaşındaki erkek hastanın, All-on-4 dental implant
konsepti ile her iki çene için rehabilite edilmesi
sunulmaktadır. Hastanın 2 yıl izleminde herhangi
bir komplikasyon olmadığı ve fizyolojik olarak
kabul edilen periimplant kemik kayıpları dışında
kayıp yaşanmadığı görülmüştür. Bu tedavi
sayesinde tam teşhisi konulamamış bir sendrom
sebebiyle oligodontik olan hastanın fonksiyonel ve
estetik beklentileri yeterince karşılanabilmiştir.
