NÖTRAL BÖLGE KONSEPTİ İLE TOTAL PROTEZ ÜRETİMİ: BİR OLGU SUNUMU

Şiddetli rezidüel kret rezorpsiyonu olan ve implant tedavisinin mümkün olmadığı hastalarda geleneksel total protez yapımı zorlaşmaktadır. Protezin stabilitesini ve uyumluluğunu artırmak için nötr bölge konsepti uygulanabilmektedir. Nötral alan konsepti, özellikle ileri kemik yıkımı olan hastalarda, fonksiyonel kuvvetlerin ortadan kaldırıldığı nötral bir alanda protez üzerine yapay diş yerleştirilmesi nedeniyle stabilizasyonu önemli ölçüde iyileştirmektedir. Bu olgu sunumu, implant tedavisinin mümkün olmadığı ileri derece kemik harabiyeti olan hastada nötral alan belirlenerek geleneksel tam protez üretimini göstermeyi amaçlamaktadır.

FABRICATION OF TOTAL PROSTHESIS USING NEUTRAL ZONE CONCEPT: A CASE REPORT

In patients with severe residual ridge resorption and where implant treatment is not possible, traditional complete prosthesis construction becomes difficult. The neutral zone concept can be applied to increase the stability and compatibility of the prosthesis. The neutral zone concept significantly improves stabilization, especially in patients with advanced bone resorption, by placing an artificial tooth on the prosthesis in a neutral area where functional forces are removed. This case report aims to show the traditional full prosthesis production, which is produced by determining the neutral area for the patient with advanced bone destruction where implant treatment is not possible.
