Objective: The objective of this study was to determine the lip support gained by complete upper dentures using the nasolabial angle (NLA) parameter before and after the prosthesis insertion. Material and Methods: 31 patients with complete edentulism were included in the study. The epidemiological characteristics and etiology/period of edentulism were recorded. The patients received dentures made by the same 2 clinicians and the dental laboratory. Pre-treatment and post-treatment profile photographs were taken and NLA measurements were made. The conformity of the variables to normal distribution was analyzed by Shapiro-Wilk test. Dependent sample ttest was used to evaluate normally distributed variables between 2 dependent measurements. Repeated measures analysis of variance test was used to determine whether the NLA measurement changed according to gender, age, etiology, and duration of edentulism groups. Differences between groups were determined by Tukey's honestly significant difference test. p values below 0.05 were considered as statistically significant. Results: The mean baseline measurement of NLA was 97.39±11.45, the mean final measurement was 89.36±10.63. NLA decreased significantly in the final measurement. The decrease of NLA is greater in males, however the difference in age and etiology groups were not significant. Conclusion: It can be stated that complete upper dentures positively affect lip support however the relation between NLA gained and epidemiological characteristics needs further investigation.

Amaç: Bu çalışmanın amacı, üst total protezlerin sağladığı dudak desteğini protez öncesi ve sonrası nazolabial açı (NLA) parametresini kullanarak belirlemektir. Gereç ve Yöntemler: Tam dişsizliği olan 31 hasta çalışmaya dâhil edildi. Epidemiyolojik özellikler ve dişsizlik etiyolojisi/süresi kaydedildi. Hastalara aynı 2 klinisyen ve diş laboratuvarı tarafından protezler yapıldı. Tedavi öncesi ve sonrası profil fotoğrafları çekildi ve NLA ölçümleri yapıldı. Değişkenlerin normal dağılıma uygunluğu Shapiro-Wilk testi ile analiz edildi. Bağımlı örneklem t-testi, 2 bağımlı ölçüm arasındaki normal dağılımlı değişkenleri değerlendirmek için kullanıldı. NLA ölçümünün cinsiyet, yaş, etiyoloji ve dişsizlik süresi gruplarına göre değişip değişmediğini belirlemek için tekrarlı ölçümlerde varyans analizi testi kullanıldı. Gruplar arasındaki farklılıklar Tukey's HSD testi ile belirlendi. 0,05'in altındaki p değerleri istatistiksel olarak anlamlı kabul edildi. Bulgular: NLA'nın ortalama başlangıç ölçümü 97,39±11,45, ortalama son ölçümü 89,36±10,63 idi. NLA son ölçümde anlamlı olarak azalmıştır. NLA'daki azalma erkeklerde daha fazladır, ancak yaş ve etiyoloji grupları arasındaki fark anlamlı değildir. Sonuç: Tam üst protezlerin dudak desteğini olumlu yönde etkilediği söylenebilir ancak kazanılan NLA ile epidemiyolojik özellikler arasındaki ilişkinin daha fazla araştırılması gerekmektedir.
