FAZEKAS University of Szeged, Department of Dentistry and Oral Surgery UP-TO-DATE TREATMENT OF THE PARTIAL EDENTULOUS DENTITION (A CASE REPORT) Nowadays the patients request more and more to wear a fixed tooth replacement which can be fabricated without the removal of tooth substance of the natural teeth, since the preparation of the teeth associates comes with a loss of hard substance and may involve a risk of a damage of the dental pulp. In the case of the partial edentulousness a suitable me­thod for the implant prosthetic rehabilitation is the tooth-for­­tooth replacement. The great advantage of this method is that the single crowns are very similar to the natural teeth in appearance and in function as well. The maintenance of the oral hygiene is not more complicated than in the case of natural teeth, it does not need any special tool, and the comfort of the patients is not disturbed. We demonstrate a case from the planning to the final steps, in which all the missing teeth were replaced by dental im­plants. According to the “backward planning” a wax up was made. By the help of the surgical stents the implants were set into the right position. An open sinus elevation was car­ried out in the left maxilla, and a closed sinus elevation in the right maxilla to gain enough bone height. After the healing period metal-ceramic crowns were fabricated and cemented on the abutments. As the final step of the treatment a mu­­cogingival surgery was performed for the extension of the attached gingiva. This case demonstrates very well the advantage of single tooth replacement, since today the technical conditions for this type of rehabilitation are given. L. RÓTH,1 Z. HAJDÚ,2 DR. P. HERMANN,3 DR.

Alloy male parts can either connect to acrylic female members, or another option is the use of alloy primary and secondary parts. Those two groups differ in method of con­struction and retention mechanism as well. A functional dental prosthesis can be guaranteed only if particular care is taken in selection between the above­­mentioned elements. Utilized attachment elements have an impact on time parameters of dental restorations’ survival. The anchoring of the prosthesis to the remaining dentition is an all important determinant to compensate the torqueing forces and occlusal load transmitted to abutment teeth. Appropriate attachment selection is a key factor for the design to reduce lever arm distance. A well designed prosthesis conforms to functional and aesthetic standards: ensures convenience for the patient, makes cleansing of denture easy, provides uniform stress distribution, sufficient retention and stabilization. Male and female part selection has a considerable influence on these characteristics. Both alloy-acrylic and alloy-alloy type attach­ments can contribute to successful construction of the pros­thesis, if specific requirements are analised and the different retention mechanism of various attachment use are properly applied. In Hungary alloy-acrylic type of attachments are popu­larized, however, considering requirements to provide a ra­tionale for appropriate attachment selection, alloy-alloy type connections show more advantages and a wider range of indications.

SCULEAN Department of Periodontology, University of Nijmegen, Nijmegen, The Netherlands PERIODONTAL TREATMENT MODALITIES IN THE AESTHETIC ZONE AROUND NATURAL TEETH Modern periodontal therapy aims not only to arrest the disease process and to reduce or to eliminate periodontal pockets but also to improve the final aesthetic outcome. Various treat­ment modalities have been introduced during the last decades in order to predictably restore to lost hard and soft tissues around natural teeth thus enhancing both function and aes­thetics. The aim of the present lecture is to give an overview on the various types of treatment modalities for restoring the lost hard and soft tissues around natural teeth. Based on the available evidence from the literature conclusions will be drawn regarding the indications, contraindications, predict­ability and the long term results obtained following these procedures.

Need for using an instrument to measure levels of oral-health-related dysfunc­tion, disability and discomfort is largely expected in Hun­gary. The new Hungarian instrument was developed according to standards (Slade and Spencer 1994). The original English
