Purpose: Removal of fixed prosthetic restorations on the supported tooth is required due to pain, apical pathology, facet fractures, cavities, and renovation. This study aims to find out especially the reasons for removal of fixed prosthetic restorations that have removal indications; to observe their state of occlusion with the opposite jaw; and to assess the periodontal state and to compare removal methods (between traditional removal methods and using KaVo CORONAflex method). Material and method: This study was carried on 160 patients who age ranged between 19 and 75 (94 women, 66 men). Totally, 815 units of prtotheses (800 bridge and 15 crowns) are evaluated. 6 of them (%3,8) had full metal restorations, 27 of them (%16,9) had metal-acrylic, 111 of them (%69,4)had metal-ceramic and 16 of them (%10) had all ceramic crown and bridge restorations. In addition to the personal informations of the patients; the type of restorations, the number of units, the presence of wings, the material of restoration was made of, the time duration of use, reasons for removal, the periodontal state, the state of occlusion with the opposite jaw, and removal method of the fixed prosthtic restorations that have removal indications were recorded on previously prepared forms. Mann-Whitney U, Ki Kare test was applied to compare groups (α=0,05). Results: The time duration of use of bridge and crown restorations was between 0 and 28 years, and it was 6.18 years in average. The relations between the reasons for removal and duration of use, the type prosthetic restorations materials and duration of use (p<0,05) and reasons of removal and department had request for removal were considered to be significant (p═0,000). Conclusion: The main reason for the removal of the restorations was apical pathology. The material of restoration was made of affects duration of use. Removal indications damage to tissues less with KaVo CORONAflex

SABİT PROTETİK RESTORASYONLARIN SÖKÜM NEDENLERİNİN ARAŞTIRILMASI VE GELENEKSEL SÖKÜM YÖNTEMLERİ İLE KaVo CORONAflex RESTORASYON SÖKÜCÜSÜNÜN KARŞILAŞTIRILMASI

Amaç: Destek dişte ağrı, apikal patoloji, faset kırığı, çürük ve yenileme nedeniyle sabit protetik restoras- yonların sökümü gerekmektedir. Bu çalışmada söküm endikasyonu konulan sabit protetik restorasyonların özellikle söküm nedeni, periodontal durumun değer- lendirilmesi ve söküm yöntemlerinin karşılaştırılması (geleneksel söküm yöntemleri ile KaVo CORONAflex kullanılan yöntem) amaçlanmıştır.

Gereç ve yöntem: Çalışma yaşları 19 ve 75 arasında değişen 160 kişi (94 kadın; 66 erkek) üzerinde yapıldı. 800’ü köprü protezi, 15’i kuron protezi olmak üzere toplam 815 üye restorasyon söküldü. Bu restorasyonların 6’sı (%3,8) tam metal kuron, 27’si (%16,9) metal-akrilik, 111’i (%69,4) metal-seramik ve 16’sı (%10) tam seramik kuron ve köprü protezleridir.  Hastaların kişisel bilgileriyle birlikte, söküm endikasyonu konulan sabit protetik restorasyonların, üye sayısı, kanatlı olup olmadığı, yapıldığı materyal, kullanım süresi, söküm nedenleri, periodontal durum ve söküm yöntemi hazırlanan formlara kaydedildi. İkili karşılaş- tırmalar için Mann-Whitney U, Ki Kare testinden yararlanıldı (α=0,05).

Bulgular: Köprü ve kuron restorasyonları için kullanım süresi 0-28 yıl arasında değişmekle birlikte ortalama kullanım süresi 6,18 yıldır. Restorasyonun söküm nedeni ile kullanım süresi, protezin yapıldığı materyal ile kullanım süresi (p<0,05) ve restorasyonun sökümünü isteyen bölüm ile söküm nedeni arasındaki ilişki anlamlı bulunmuştur (p=0,000).    

Sonuç: Restorasyonların sökümünde ilk neden apikal patolojidir. Restorasyonun yapıldığı materyal kullanım süresini etkilemektedir. KaVo CORONAflex ile söküm işleminde dokulara daha az zarar verilmektedir.
