Abstract

Restoring deep, extensive carious lesions and subgingival situations can be challenging due to difficulties in placing matrices and achieving isolation. This article describes a technique utilizing individually designed digital matrices for challenging cases, offering an alternative solution aiding the reconstruction of the missing dental structures. Three cases are presented with difficult subgingival cavities or severe destruction of dental hard tissues, where a custom-made matrix was used to bridge the challenges of matrix placement and isolation. Digital impressions of dental arches were taken, and custom-made metal instruments were manufactured through computer-aided design and subsequent sintering. These instruments aided the elevation of deep margins and the reconstruction of the teeth. The presented technique yielded favorable results in terms of accuracy and feasibility for these challenging cases. However, it should be noted that the procedure requires additional time and incurs costs for the necessary elements. [ABSTRACT FROM AUTHOR]

Abstract

Bevezetés: Kutatásunkban arra kerestük a választ, hogy két eltérő töméstechnika esetében van-e különbség a rövidüvegszál megerősítésű kompozit (short fiber-reinforced composite, SFRC) tömőanyag zsugorodása miatt kialakult repedésekszámában.Anyag és módszer: Két csoportban, 20-20 extrahált bölcsességfogba standardizált nagyságú MOD üreget preparáltunk,majd a fogakat az alábbiak szerint restauráltuk SFRC-vel: 1. csoportnál bulk, rétegzés nélküli technikával, 2. csoportbanpedig ferde rétegzéssel 2 mm vastag rétegekben. Mindegyik minta esetén az SFRC-t 1 mm kompozittal fedtük.A tömés elkészítését követően D-Light Pro lámpával megvizsgáltuk a fogzománcot, és a keletkezett repedések számátrögzítettük. Az összrepedésszámot egy hét elteltével is rögzítettük.Eredmények: A két töméstechnika között az eltérés nem szignifikáns a repedésszám tekintetében. 1 héttel későbba bulk, rétegzés nélküli csoportban 4,95 (340%-os növekedés), a rétegzéses csoportban 4,30 (410%-os növekedés) voltaz átlagos repedésszám. Ez a korábbi adatokhoz képest szignifikáns eltérés (p = 0,000). A két töméstechnika közötta végső összrepedésszám tekintetében nem tapasztaltunk szignifikáns eltérést.Következtetések: SFRC anyag esetén a vizsgált két töméstechnikával közel azonos mértékű repedésképződés jönlétre, és mindkét esetben jelentősen megnő a repedések száma a posztpolimerizációs időszakban.

Abstract

Purpose: Molar MOD (mesial‐occlusal‐distal) cavity preparation weakens relative cuspal stiffness by up to 63%, often resulting in cuspal fracture. This investigation inspects fracture resistance of MOD cavities restored using direct composite restoration. Materials and Methods: 120 extracted, intact mandibular molars were selected. MOD cavities with different depth/wall thickness were prepared in 9 groups (n = 12): A: 3 mm/3.5 mm, B: 3 mm/2.5 mm, C: 3 mm/1.5 mm, D: 5 mm/3.5 mm, E: 5 mm/2.5 mm, F: 5 mm/1.5 mm, G: 7 mm/3.5 mm, H: 7 mm/2.5 mm, I: 7 mm/1.5 mm. Specimens with 7 mm deep cavities received root canal treatment. The teeth were restored with dental composite. Maximal fracture strength test was conducted. Intact natural teeth were used as control. For statistical analysis Kruskal‐Wallis ANOVA with post‐hoc pairwise comparisons was used (α = 0.05). Results: Significant difference was indicated between the control and groups D, E, F, G, H, and I. No significant differences were found between the A, B, C groups and the control. Comparing the 5 and 7 mm cavity depth groups, there was no statistical difference between any of them. Conclusions: Within the limitations of this investigation, the following conclusions can be drawn regarding molar teeth with a MOD cavity: 3 mm or shallower cavities can be restored to the physiological fracture strength with direct composite restorations; 5 mm or deeper cavities cannot be restored to the physiological fracture strength with direct composite restorations. Cusp thickness does not significantly influence fracture strength in molar MOD cavities with a direct composite restoration. [ABSTRACT FROM AUTHOR]
