Ортопедичне лікування дефекту зубного ряду у фронтальному відділі з компенсованою формою патологічної стертості адгезивним зубним мостоподібним протезом

In pathological attrition, teeth change the anatomical shape of the crown part of the teeth and the character of the mastication pressure distribution on the cutting and chewing surfaces. Dentition defects accompany this process and need the use of adhesive dental bridge (ADB), which is more suited to modern biotechnological requirements. Aim. To statistically analyze the dimensions of the oral surfaces of the anterior teeth in patients with a compensated form of pathological attrition, and to evaluate the potential applicability of these teeth as abutment elements for ADB. Materials and methods. We selected 30 patients (18 men and 12 women) aged 35–55 years with first-degree (attrition up to 1/3 of crown height) or second-degree (attrition up to 2/3 of crown height). From these, we formed two groups of 15 patients each. A third control group comprised 15 patients with intact dentition and physiological occlusion. We used a mathematical model from prior work for rational planning of ADB abutments in specific patients. Results. The examination results of 45 patients (270 teeth) conducted on models allowed us to determine the oral surface area of the anterior teeth, depending on the degree of pathological attrition. Conclusions. The mean occlusal surface areas of upper and lower jaw teeth have been identified. Based on clinical and laboratory experiments, this made it possible to plan the supporting elements of ADB for patients with a horizontal form of pathological dental attrition.
