[The effect of hygiene on the fixed prosthetic structure surroundings]

Na uzorku od 50 ispitanika pokušalo se utvrditi odnos higijene i fiksnoprotetskog izdjelka. \u27Pomoću parodontoloških indeksa za mjerenje plaka i stanja gingive po Löe i Sillnesu, te kliničkom opservacijom ocjenjeno je stanje gingive, količina i mjesto kumulacije plaka i taloženje kamenca. Dobiveni rezultati pokazuju da ne postoji značajna uvjetovanost između trajnosti rada i kliničkog pogoršanja gingive, tj. da duži vijek protetskog nadomjestka ne mora uvjetovati patološke promjene marginalne gingive ukoliko pacijent održava optimalne higijenske uvjete. \u27Nadalje, plak se u svim slučajevima gdje je prisutan taloži mterdentalno, između plastičnih faseta i u fisurama izraženijih okluzijskih ploha krunica. Istodobno rezultati pokazuju da je kumulacija plaka u pojedinim slučajevima veća na prirodnim zubima nego li na izdjelku. Slijedi zaključak da korektno izrađena fiksnoprotetska konstrukcija može dugo vremena ostati funkcionalna, pa čak i na reduciranom, ali saniranom fundamentu. Provodeći plan terapije s parodontologom, protetičar može očekivati bolju prognostičku ocjenu održanja i očuvanja bioloških osnova te veću uporabnu trajnost fiksnog rada u higijenski čistim ustima .A relationship between hygiene and fixed prosthesis was studied in a sample consisting of 50 subjects. The state of gingiva, the amount and site of plaque accumulation, and calculus deposition were assessed by means of periodontal indices for the plaque and gingival state determinations according to Loe and Sillness, supplemented by clinical observations. The results obtained have shown that there is no significant causal relationship between the duration of work and clinical deterioration of the state of gingiva, i.e. that a prolonged life of the prosthetic replacement need not cause any pathological alterations to marginal gingiva provided the patient keeping to optimal hygienic procedures. Furthermore, wherever present, the plaque is interdentally deposited, i.e. between the plastic facets and in the fissures of more pronounced occlusal crown surfaces. Atthe same time, the results have indicated the plaque accumulation in some cases to be greater on natural teeth than on the artificial structures. Thus, we can conclude that a properly manufactured fixed construction may function well for quite a long period of time, even on a reduced but treated foundation. Implementing the plan of therapy together with a periodontolog ist, a prosthetist can expect a better prognostic evaluation of the maintenance and preservation of the biological foundation, and a prolonged usability of the fixed construction in a hygienically clean /mouth
