Abstract		Background. Along with systemic factors it has been shown that local factors such as inadequate restorative dentistry may result in accelerated alveolar bone loss. The aim of the study was to examine the prevalence of overhanging approximate restorations and to quantify their effect on marginal alveolar bone in comparison with the effect of intact teeth surfaces and surfaces with well-fitting amalgam restorations. Materials and metodst. Panoramic radiographs of 671 randomly selected patients, aged 18-75 years (x=4.8) were examined. Interproximal bone loss around teeth with overhanging amalgam restorations was measured and compared to bone loss around well-fitting amalgam restorations and adjacent to intact approximate surfaces. Results. The prevalence of overhanging approximate amalgam fillings was 19%. Overall alveolar bone loss was greater around teeth with overhanging amalgam restorations than around teeth with well-fitting restorations. The lowest bone resporption was adjacent to intact approximate teeth surfaces (all statistically significant, p > 0.01).
Summary		Izhodišča. Dokazano je bilo, da poleg sistemskih dejavnikov tudi neusrezne zobne plombe in prevleke pospešijo izgubo alveolarne kosti. Namen študije je bil ugotoviti pogostnost previsnih plomb in oceniti ter primerjati vpliv previsnih in dobro prilegajočih se plomb oziroma intaktnih zobnih površin na rob alveolarne kosti. Materiali in metode. Prelgedano je bilo 671 ortopantomografskih posnetkov naključno izbranih pacientov starih 18-75 let (x = 43,8). Izmerjeno izgubo kosti v interdentalnem prostoru ob previsni plombi smo primerjali z izgubo ob dobro prilegajočih se plombah in intaktnih zobeh. Rezultati. Pogostnost previsnih aproksimalnih amalgamskih plomb je bila 19%. Izguba alveolarne kosti ob zobeh s previsnimi aproksimalnimi amalgamskimi plombami je bila statistično značilno večja kot ob zobeh z dobro prilegajočimi plombami (p <0,01). Kostna resorpcija ob intaktnih zobeh je bila najmanjša (p <0,01). Zaključki. Previsne amalgamske plombe so pomemben dejavnik, ki vpliva na potek parodontalne bolezni. Nujna je pozorna modelacija aproksimalnih plomb, še zlasti predelov ob gingivalni stopnici. obstoječe previse je potrebno odstraniti, kar prepreči nastanek oz. zmanjša hitrost napredovanja parodontalne bolezni.
