IntrusÕon of Over-Erupted Maxillary Molar Teeth By UsÕng MÕnÕ-Screw Anchorage

Year 2014, Volume: 41 Issue: 1 - Volume: 41 Issue: 1, 1 - 7, 01.02.2014

Abstract

Over-erupsiyon of upper molars and premolars following loss of the opposing tooth is a common clinical finding. In such cases, when the interocclusal space is reduced, intrusion treatment with miniscrew implants of the upper posterior teeth to correct a canted occlusal plane could be an ideal treatment strategy for the mandibles’ prosthetic treatment with implant supported fixed dentures. METHODS : The study was comprised of 9 patients aged 27 to 59 years; mean 36,4 years with overerupted maxillary posterior teeth. Four self-drilling miniscrew implants 2 for buccal alveolar bone region and 2 for posterior palatal area were inserted. An elastomeric chain applied 80 g of force to each overerupted maxillary posterior teeth. The elastomeric chain was replaced every three weeks. Panoramic radiograms were obtained preintrusion and immediately after completion of the intrusion. The panoramic radiograms were superposed and the distances between the occlusal planes of first molar teeth were measured. Then osseointegrated implants placed in the opposing posterior mandible region and prosthetic treatments were finalized. RESULTS: Upper posterior teeth were intruded with an average of 4,42± 0,62 mm according to changings of the first maxillary molars’ occlusal planes, after in a mean of 4,89 ± 1,00 months active treatment. There were not any rooth resorption determined during the treatment acccording to radiograms .A good occlusion was achieved with implant supported fixed partial dentures for mandible after treatment

Over-erüpte üst molar dişlerin mini-vida ankrajı ile intrüzyonu

Year 2014, Volume: 41 Issue: 1 - Volume: 41 Issue: 1, 1 - 7, 01.02.2014

Abstract

Amaç: Antagonist dişlerin kaybedilmesi sonucunda dişlerin kontağını kaybetmesi sebebi ile over-erupsiyona sıklıkla karşılaşılan bir durumdur. Bu durumda over-erupsiyona uğramış dişlerin ortodontik tedavi ile intrüze edilmesi yoluyla interoklüzal mesafenin arttırılması, kayıp dişlerin protetik olarak yerine konulmasına imkân sağlayacak en ideal yöntem olarak öne çıkmaktadır. Bu çalışmanın amacı; implant destekli sabit protetik restorasyonlar için yeterli interoklüzal mesafe kazanmak amacıyla üst molar bölge intrüzyonu sırasında ankraj amaçlı mini vida kullanımının etkinliğinin araştırılmasıdır. Gereç ve Yöntem: Çalışmaya over erüpsiyona uğramış üst molar dişlere sahip 27-59 yaşları arasında ortalama yaş: 36,4 6 erkek, 3 bayan toplam 9 birey dahil edilmiştir.İki adet vestibul iki adet palatinal bölgeye olmak üzere 4 adet self drill mini vida yerleştirilmiştir. Vidalar arasına diş başına 80 g kuvvet uygulayacak şekilde elastik zincirler uygulandı. Elastik zincirler 3 haftada bir değiştirildi. Hastalardan intrüzyona başlamadan önce ve intrüzyonun tamamlanmasını müteakiben panoramik radyografiler alındı. Çakıştırılan radyografiler üzerinde, çalışma bölgesinde bulunan birinci şlerinin oklüzal düzlemleri arasındaki mesafe ölçülerek intrüzyon miktarları hesaplandı. Ortodontik tedaviyi müteakiben bütün hastalara osteointegre implantlar uygulandı ve protetik restorasyonlar yapıldı
