FOGORVOSI SZEMLE »99. évf. 2. sz. 2006. 65 By using a facial bow along with the individual articulator, the authors successfully established the unilateral group function, namely the unilateral balance occlusion which is required in such cases in order to provide unobstructed group functioning during laterotrusion on both sides. As a result of normalising the occlusal relationships, the patient’s complaints were eliminated. The authors have managed to maintain the effectiveness of the treatment by organising regular check-up examinations and patient care. The patient is satisfied and has been wearing the restorations without complaints for two years. The success of the treatment can be ensured by planning the complex therapy accurately, in the full knowledge of the diagnostic requirements and by organising the patients’ care, after the treatment is accomplished, in order to maintain the achieved results.

FEJÉRDY Semmelweis University, Faculty of Dentistry, Department of Prosthodontics, Budapest * RELATION BETWEEN THE TMJ AND THE DENTAL STATUS BASED ON A CROSS SECTION STUDY Introduction: The literature presented high prevalence data about the temporo-mandibular joint (TMJ) disorders in the Hungarian adult population. Objective: The authors analized the relationship between the prevalence of TMJ disorders in the Hungarian adult population according to age, gender and region. The role of dental status, especially the edentulousness and the types of prosthodontic appliances affecting the developement of TMJ disorders were evaluated. Material and methods: In Hungary a dental epidemiological study was performed following the WHO indications (WHO, 1998) by the calibrated dentists of the Department of Prosthetic Dentistry (Semmelweis University, Budapest) in 2003-2004. Altogether 4606 persons (2923 women, 1683 men) participated in the study. Probands were selected randomly from the population attending the compulsory lung screening examinations. To make a representative sample of the whole population in the country, the chosen localities covered all regions, the capital, the large towns and villages as well. During the physical examinations we registered the following symptômes: pain, clicking, tenderness, restricted mouth opening, deviation of mentum. The data were coded on special sheets by computer on the spot. Statistical analysis was performed using SPSS for Windows 10.0 version statistical software. Results: 1845 patients (40.06%) from a total of 4606 were affected in TMJ disorders, such as deviation (1298 persons; 28.18%) and clicking (1083 persons; 23.51%). 67.26% of the affected patients had only one symptom, 31.38% had two symptoms at the same time, and the remaining 1.36% had three or four of them. According to age, the most affected group was those between 35 and 44 years, where the deviation (31.15%) and clicking (27.14%) were the leading symptoms. It is to be noted, that - according to the classification of partial edentulousness by Fábián and Fejérdy - the incidence of class 1A was the highest (56.24% in the upper and 54.27% in the lower arches). Although in this age group the rate of replacement of the teeth was less than 50% (47.63% in the upper arch where 92% are fixed partial dentures, and 24.02% in the lower arch where 93% are fixed partial dentures). The TMJ disorders were more common in women than in men; clicking in women: 27.19%, in men: 14.64%; deviation in women: 30.19%, in men: 24.97%. The rate of prosthetically replaced teeth was also higher in women (the frequency of the fixed and removable partial dentures in the upper arches were 50.49% in women and 36.01% in men, and in the lower arches it was 35.99% in women and 25.25% in men. The prevalence of deviation and clicking were the highest in the South-Hungarian region (42.42%; 27.27%). The lowest prevalence of TMJ disorders was found in the West- Central region (deviation: 18.84%; clicking: 21.38%). It can be noted, that the lowest prevalence of TMJ disorders can be found in the youngest (17-19 year olds) and the oldest (75-94 year olds) age groups, where the teeth are more healthy or there was no possibility to make fixed partial denture.

However, this dose not exclude the possibility to improve these properties in order to enhance their biointegration. At the present stage our studies focus on the improvement of the biointegration features of the titanium. It is well-known, that when an alloplastic material is placed in the living tissue environment the surface properties of the material are determinant. On one hand, these properties influence the morphological integration in the micrometer scale, and on the other hand the molecular attachment which is occurring in the nanometer scale. Beside this, the chemical structure of the surface is also an important factor in the interaction of the alloplastic material with the biological environment. The following surface modifications were performed: ablation of the surface with ArF excimer laser, coating the surface with OOP, and self-assembled polypeptide multilayers. Our results proved that polypeptide multilayer coatings favour osteoblast proliferation.
