Aim: Conical crown retained dentures
has been widely and increasingly used especially in patients with periodontal
problems. The studies about conical crown prosthesis are regarding indications
and construction types of the prosthesis. The studies about the retention and
loss of retention by usage are few. The aim of this study is to evaluate the
changes in retention by usage of plastic resin based superstructures in conical
crown retained dentures. In this in vitro study, 10 samples in each group are
prepared for three different seconder crown material, in four different tooth
groups.

Method: The
primer crowns are prepared to have 2°of angles are casted form Cr-Ni alloy. The
superstructures are also made of Cr-Ni alloy, Acetal D and Vectris materials.
The insertion and separation motion of the dentures were simulated by the
experiment device which is specially designed by Caniklioğlu. The first
retention forces in crowns were measured and then the values were noted after
the insertion and separation procession of 500, 1500, 3500 times.

Findings: In this
study, we achieve to compare the loss of retention forces in three different
seconder crown materials in the usage of 24 months.







Conclusion: The
results show that the seconder crowns made of metal have the best retention
values and the least retention decrease per cent is shown by Vectris seconder
material.

Amaç: Periodontal
problemi olan hastalarda konus kuronlu protez kullanımı oldukça yaygındır ve
artmaktadır. Konus kuronlu protezler konusundaki çalışmalar çoğunlukla protezin
yapım yöntemleri ve endikasyonu ile ilgilidir. Protezin kullanımına ait tutunma
kuvveti kayıpları ile ilgili çalışmalar sınırlı sayıdadır. Çalışmada konus
kuronlu protezlerde plastik esaslı malzemelerden yapılmış sekonder kuronların
kullanıma bağlı tutunma kayıpları üzerine çalışılmıştır. İn vitro deneylerde
dört diş grubundan, üç değişik sekonder kuron malzemesi ile 10’ar adet örnek
kullanılmıştır.



Yöntem: Cr-Ni
alaşımdan 2°’lik açı ile primer kuronlar hazırlanmış ve üzerlerine Cr-Ni
alaşımı, Vectris ve Asetal-D malzemelerinden sekonder hazırlanmıştır.
Caniklioğlu tarafından tasarlanan aygıt kullanılarak protezin takılıp
çıkartılma işlemleri taklit edilmiştir. Kuronların ilk tutunma kuvvetleri
ölçülmüş daha sonra 500, 1500 ve 3500 takıp çıkartma sonucundaki tutunma
kuvveti değerleri tablolara not edilmiştir.



Bulgular: Bu
çalışma bize 24 aylık protez kullanımı sonucunda meydana gelen tutunma
kuvvetlerini ve kayıplarını karşılaştırma imkanı vermiştir.



Sonuç: En iyi
tutunmanın metal sekonder kuronlarda olduğu, tutunma kayıplarında en düşük
yüzde değerlerinin ise Vectris sekonder kuronlarda olduğu sonucuna varılmıştır.
