Abstract

Many dental problems, pathological attrition, and a decrease in vertical jaw relation are observed due to jaw movements above physiological limits. The present case report has described the digital workflow for the rehabilitation of a patient with partial tooth deficiency, advanced attrition, and loss of vertical dimension using full-arch partial veneered monolithic zirconia fixed prosthetic restorations on the lower and upper jaws.
A 55-year-old male patient was referred to our clinic with complaints of his chewing and aesthetic problems. As a result of clinical and radiographic examination, dental/implant-supported full-arch fixed prosthetic restorations have been planned for both jaws to replace the destroyed tooth tissue, increase the vertical dimension and eliminate tooth deficiencies. After the pre-prosthetic treatments and osteointegration duration of dental implants in the place of 36 and 37 numbered teeth, tooth preparations were performed and digital impressions and interocclusal records at the desired vertical dimension were obtained using an intraoral scanner. After the virtual design of full-arch partial veneered monolithic restorations was completed, the temporary try-in restorations were fabricated using a 3D printer for checking the fit, appearance, and occlusion. The required controls and corrections were done, the definitive final restorations were fabricated with the guide of renewed occlusal registrations, and the facial surfaces were veneered with feldspathic glass-ceramic material.
The patient's chewing and aesthetic complaints with loss of vertical dimension were rehabilitated with digital workflow using full-arch partial veneered monolithic zirconia fixed prosthetic restorations. During the 3 years of follow-up, the patient doesn’t have any joint, function, phonation, or aesthetic problems.

Tam ark parsiyel veneerli monolitik zirkonya sabit protetik restorasyonda dijital iş akışı: Bir vaka raporu

Abstract

Fizyolojik sınırların üzerindeki çene hareketleri ve çiğneme sonucunda pek çok dental problemle beraber, patolojik atrizyon ve dikey boyutta azalma görülmektedir. Bu çalışmada parsiyel diş eksikliği, ileri seviyede atrizyon ve dikey boyut kaybı görülen bir hastanın dijital iş akışıyla alt ve üst çene tam ark parsiyel veneerli monolitik zirkonya sabit protetik restorasyonlarla rehabilite edilmesi anlatılmaktadır.
55 yaşındaki erkek hasta, çiğneme ve estetik şikâyetleri ile kliniğimize başvurmuş, klinik ve radyografik inceleme sonucunda, harap olmuş diş dokusunun yerine konması, dikey boyutun artırılması ve diş eksikliklerinin giderimlesi için her iki çeneye diş/implant destekli tam ark sabit protetik restorasyonlar yapılması planlanmıştır. Preprotetik tedavilerin, 36, 37 nolu dişlerin yerine yerleştirilen dental implantların osteointegrayonunun ardından, diş preparasyonları yapılmış ve ağız içi tarayıcı kullanılarak dijital ölçüler ve planlanan okluzal yükseklikte kapanış kayıtları alınmıştır. Sanal modeller üzerinde fasiyal yüzeyleri veneerlenecek şekilde tasarlanan monolitik restorasyonların uyumunun kontrol edilmesi için 3B yazıcı kullanılarak geçici restorasyonlar imal edilerek prova yapılmıştır. Gerekli düzeltmelerin ardından kapanış kaydı yenilenmiş ve fasiyal yüzeyleri feldsatik seramikle veneerlenen monolitik zirkonya materyalden final restorasyonlar üretilmiştir.
Hastanın dikey boyut düşüklüğü, çiğneme fonksiyonu bozukluğu ve estetik kaygıları tam ark zirkonyum restorasyonlar ile giderilmiştir. Yapılan 3 yıllık kontrollerde hastada herhangi bir eklem, fonksiyon, fonasyon ve estetik problemin oluşmadığı görülmüştür.
