The increasing (almost 100 per cent) success of dental implantation nowadays have a strong influence on prosthetic planning, contributes to a higher level of dental rehabilitation and guarantees a better quality of life for pa­tients. Although at different rates, missing teeth might occur at any age. The treatment of upper anteriors at an early age is especially important because of aesthetical and phonetical reasons. The prosthetic treatment in childhood and adoles­cence might become necessary because of caries and con­sequence illnesses; injury of teeth; tooth agenesis (hypodontia, oligodontia, partial/total anodontia); and developmental dis­turbances of tooth structure. The role of dental implants is increasing in treating aplasia and replacing teeth removed or lost in accidents. The authors present their experiences and results in this field. DR. A. PONGRÁCZ,1 A.

The questioning revealed daily consumption of a diet­­cocktail, containing apple vinegar, lemon and honey for the last two years. The diet was completed by drinking 3 dl red wine every evening. For the main meals he preferred food rich in fibre. Three times a day he brushed his teeth strongly. The clinical examination has shown severe hard substance losses on occlusal surfaces of the molars, dentin sensibili­ties to cold and mechanical excitement. The acid erosion and abrasion touched the lingual surfaces of superior ca­nines and incisors in different degrees. Generalised tartric debris could be observed both supra- and subgingival. The orthopantonogramm has shown a generalized, horizontal alveolar bone loss. On the diagnostic stone cast, the tehnician waxed up the lost tooth structures, previewing the final result. After pro­fessional hygienic treatment, the lower front bridge - made of resin - was eliminated, and the compromised abutments where extracted, just like the wisdom teeth (third molars). New abutments where used, with supragingival preparations, for the front bridge. Partial crown-, overlay- and lingual veneer preparations where performed for the molars and canines with lost substances. For the next two months, the patient got a protection splint, also serving for adaptation to the new occlusal relations. The front bridge was made of Co-Cr alloy veneered with hybrid ceramic (Estenia). The partial crowns, overlays and lingual veneers where also made of hybrid ceramic. The bridge was fixed with GC Fuji Plus - resin-inforced glassionomer cement, and the other devices with Panavia F 2,0 dual curing composite cement. DR. M. RADNAI,1 DR. I. GORZÓ,1 DR. E. NAGY,2 DR. E.

However some other researchers could not find such an association. The aim of our study was to examine if there was an as­sociation between early periodontitis of the pregnant women and preterm birth. Material and methods: In total 161 healthy women (mean age 27.6 ys) were included in this cross-sectional study. Preterm birth was defined if the patient had a threatening premature labor during pregnancy, or spontaneous preterm labor, and/or if the weight of the newborn was less then 2500 g. In the control group women had delivery after 37th gestational week and the weight of the newborn was more then 2500 g. The examinations were carried out within three days after delivery. Detailed periodontal status was taken, including plaque index, calculus frequency, probing depth, bleeding on probing. Early periodontitis was defined, if the patient had >4mm probing depth at least at one site and bleeding on probing occurred at >50% of her teeth. Results: A significant association was found between the weight of the newborns and the existing periodontitis of the mother. Weight of the newborns was 28 34.5g in the periodonti­tis and 3180.3 g in the control group, the difference was significant (p = 0.004). According to the result of the multi­variate logistic regression, mothers with early periodontitis had 3.32 times greater odds of preterm delivery or low birth weight, than did women without periodontitis. Conclusion: The results of the study show, that the early periodontitis of the pregnant woman may be an independent risk factor for preterm birth.
