EVALUATION OF EFFECT OF IMPRESSION TECHNIQUES TO SATISFACTION OF EDENTULOUS PATIENTS TREATED WITH IMPLANT-RETAINED OVERDENTURES: A PILOT STUDY

ABSTRACTAim: The implant-retained mandibular overdentures are standard care of the edentulous patients. Function, phonetics and satisfaction of the patient are decisive to acquire prospering treatment results. Passive fit between the implants and the denture framework is important for restoration of the implants. Accurate impression is primary factor to obtain fitted denture. Several impression techniques (single stage, double, and functional impression techniques) described making impression of the implant-retained overdentures. The aim of this study was to evaluate influence of two different implant-retained overdenture impression techniques to quality of life of the patients.  Materials and Method: Six women edentulous patients participated in this study. 2 implant-retained overdentures were fabricated using two different impression techniques per patient. The first overdentures were produced using the single stage close tray impression technique. After 6 months, the functional impression technique was used to fabricate the second overdentures. 13 questions were asked to the patients about both of their dentures in the first follow up visits those two days after the delivery of their overdentures. The Mann-Whitney U statistical analysis was performed on the acquired data. Results: The patients satisfied with the performance of both of the overdentures. Half of the participants complained soreness of the gums under the overdenture that was fabricated using the close tray impression technique. Other questionnaire items were shown no statistically significant differences. Conclusion: The single stage close tray, and the functional impression techniques are used confidently to fabricate the implant-retained mandibular overdentures. The functional impression technique decreased chair time of the post-insertion maintenance.

Fonksiyon, fonasyon ve hasta memnuniyeti başarılı tedavi sonuçları elde etmek için belirleyicidir. İmplant restorasyonlarında, implant ve protez altyapısı arasındaki pasif uyum önem arzetmektedir. Tam uyumlu protezler için ölçünün doğruluğu birincil faktördür. İmplant destekli overdenturelarda ölçünün alınması için birkaç ölçü tekniği (tek aşama, çift aşama ve fonksiyonel ölçü teknikleri) tanımlanmıştır. Bu çalışmanın amacı, iki farklı implant destekli overdenture ölçü tekniğinin hastaların yaşam kalitesine olan etkisinin değerlendirilmesidir.   Materyal ve Metot: Çalışmamıza altı kadın dişsiz hasta katılmıştır. Her hasta için iki farklı ölçü tekniği kullanılarak iki tane implant destekli overdenture protez yapılmıştır. Birinci overdenturelar, tek aşama kapalı kaşık ölçü tekniği kullanılarak hazırlanmıştır. Altı ay sonra fonksiyonel ölçü tekniği kullanılarak ikinci overdenture protezler yapılmıştır. Protezlerin tesliminden sonraki ilk kontolde hastalara protezleri ile ilgili 13 soruluk anket yöneltilmiştir. Elde edilen veriler Mann-Whitney U istatistiksel analizi uygulanarak değerlendirilmiştir.        Bulgular: Hastalar hazırlanan iki protezin de performan- sından memnun kalmışlardır. Katılımcıların yarısı kapalı kaşık tekniği ile yapılan overdenture protezin altındaki yu- muşak dokudaki yaralardan yakınmışlardır. Anketteki di- ğer sorular istatistiksel olarak anlamlı fark göstermemiştir.  Sonuç: Tek aşama kapalı kaşık ölçü tekniği ile fonksiyo- nel ölçü tekniği implant destekli overdentureları hazırla- mak için güvenle kulanılabilirler. Fonksiyonel ölçü tekniği protez tesliminden sonra harcanan hasta başı zamanını azaltmıştır. Anahtar Kelimeler: Overdenture, Hassas tutucu, Dental implant, Yapım tekniği, Ölçü
