Abstract

ABSTRACT

Introduction: In the posterior mandible, dental implants are usually used to support
fixed prostheses. In many cases, serious bone resorption occurs in this region
following tooth extraction and it is difficult to place implants in appropriate
sizes due to the limitation of vertical distance of the inferior alveolar nerve
(IAN). There are regenerative or
reconstructive procedures in the posterior mandible to provide rehabilitation
with implants in cases of excessive vertical bone loss. Repositioning of IAN is
one of the alternative methods in the literature.

Case Report: Full-mouth fixed mandibular prosthetic rehabilitation with dental
implants was planned to a
62-year-old male patient in another clinic. However in the left mandibular
posterior region, placed implants were failed twice. In radiographic
examinations approximately 5 mm vertical height was determined in the posterior
region. According to current clinical conditions, all available treatment
options were discussed with the patient and dental implant placement with nerve
transposition technique was decided. Under local anesthesia IAN was
repositioned by implementing piezosurgery and dental implants were placed
successfully. After one year follow-up there was no complaint or sensory loss.

Conclusion: At the right indications, IAN
repositioning techniques are useful surgical procedures that can be used for
the rehabilitation of the atrophic posterior mandible with dental implants.

INFERIOR ALVEOLAR SİNİR TRANSPOZİSYONU
İLE BİRLİKTE GERÇEKLEŞTİRİLEN DENTAL IMPLANT UYGULAMASI

ÖZ

Giriş: Posterior
mandibulada, dental implant uygulamaları genellikle sabit protezleri
desteklemek amacıyla uygulanmaktadır. Ancak birçok vakada bölgede yaşanan diş
kayıpları sonrasında oluşan ciddi rezorpsiyonlar nedeniyle özellikle inferior
alveolar sinirin (IAS) vertikal boyut kısıtlamaları da eklenince uygun
boyutlarda implant uygulamaları yapabilmek oldukça zor hale gelmektedir.
Literatürde bu tip aşırı kemik rezorpsiyonu bulunan durumlarda dental implant
uygulanabilmesine olanak sağlayacak çeşitli rejeneratif veya rekonstrüktif
teknikler önerilmiştir. IAS’ın yeniden konumlandırılması teknikleri de
literatürde geçen alternatif tekniklerden biridir.

Olgu Sunumu: 62 yaşında erkek
hastaya dış merkezde implant destekli tüm çene mandibular sabit protetik
rehabilitasyon planlanmıştır. Ancak sol mandibula bölgeye yerleştirilen
implantlar 2 defa tekrarlanmış ancak başarısız olmuştur. Tarafımızdan yapılan
radyolojik muayenede bölgede 5 mm kemik yüksekliği tespit edilmiştir. Mevcut
şartlar dahilinde hastaya uygulanabilecek tedavi alternatifleri açıklanmış ve
nihayetinde sinir transpozisyon tekniği ile birlikte dental implant uygulanması
kararlaştırılmıştır. Lokal anestezi altında piezocerrahi yardımıyla sinir
repozisyonu uygulanmış ve bölgeye implant uygulamaları başarıyla yapılmıştır. 1
yıllık takibin ardından hastada herhangi bir şikayet bulunmazken, duyusal bir
kayıp tespit edilmemiştir.

Sonuç: Doğru
endikasyonlarda sinir rezpozisyon teknikleri, atrofik posterior mandibular
bölgelerin dental implantlarla rehabilitasyonuna olanak sağlayan kullanışlı
tedavi seçenekleridir.
