ABSTRACT
PATIENT: The patient was a 63-year-old man with a chief complaint of dysmasesis. Following occlusal reconstruction and periodontal treatment, a complete denture and fixed partial denture with indirect composite resin were implanted in the patient. DISCUSSION: The results of this case show that regular check-up may be effective for coloration and discoloration. CONCLUSION: Indirect composite attached plaque to interdental space and pontic easily. However, combination use of toothbrush and sonic brush could improve oral health. The patient was satisfied with the function and the dental esthetic.

The purpose of this study was to evaluate the effects of acidic primers on adhesive bonding to sintered aluminum oxide (alumina). Alumina disks were primed with one of the following materials: Acryl Bond, All Bond 2 Primer B, Alloy Primer, Estenia Opaque Primer, Eye Sight Opaque Primer, M.L. Primer, MR. Bond, and Super-Bond Liquid. Specimens were then bonded with an acrylic resin initiated with partially oxidized tri-n-butylborane (TBBO), and bond strengths were determined. Unprimed specimen was employed as the control. Average bond strength before thermocycling ranged from 20.5 to 41.9 MPa, whereas post-thermocycling bond strength ranged from 0.0 to 40.0 MPa. Of the eight primers, Estenia Opaque Primer and Alloy Primer showed better adhesive performance than the other materials. It could thus be concluded that either Estenia Opaque Primer or Alloy Primer--which contained an adhesive monomer, 10-methacryloyloxydecyl dihydrogen phosphate (MDP)--was recommended for bonding alumina with TBBO-initiated resin.

PURPOSE: To examine the influence of temporary cements on the strength of the bond formed between resin-based luting agents and dentin. METHODS: An acrylic resin plate was luted to bovine dentin using one of three temporary cements; HY-Bond Temporary Cement Hard (HYB), Freegenol Temporary Pack (FTP), or Neodyne T (NDT). The control group (CON) was not treated with cement. Following the removal of the temporary cement, each dentin substrate was bonded to a silane-treated ceramic material (IPS Empress) with one of four luting agents; Super-Bond C&B (SCB), Panavia F (PAF), Nexus II (NEX), or Fuji Luting S (FLS). The specimens were immersed in water for 24 hours and the strength of the bond to shearing forces was determined. RESULTS: The bond strengths (in MPa), with statistical categories shown in parentheses were: HYB (25.7, a), CON (23.5, a, b), FTP (19.8, b, c), and NDT (16.8, c, d) for the SCB system; FTP (13.8, d, e), CON (12.9, d, e), NDT (10.6, e, f), and HYB (7.8, f, g, h) for the PAF system; FTP (9.2, e, f, g), CON (7.9, f, g, h), HYB (7.7, f, g, h), NDT (7.1, f, g, h) for the NEX agent; and FTP (5.2, g, h, i), CON (3.7, h, i), NDT (3.0, h, i), HYB (1.6, i) for the FLS agent, (P< 0.05).

The purpose of the current study was to evaluate the effect of functional monomers contained in the primers on adhesive bonding of a steel alloy. SUS XM27 steel was primed with one of the following materials; Alloy Primer, Estenia Opaque Primer, and V-Primer. The functional monomers in the primers were a phosphate (10-methacryloyloxydecyl dihydrogen phosphate; MDP) and a thione (6-(4-vinylbenzyl-n-propyl) amino-1,3,5-triazine-2,4-dithione, -dithiol tautomer; VTD) for Alloy Primer, MDP alone for Estenia, and VTD alone for V-Primer. The steel disks were bonded with an acrylic resin (Unifast Trad), and bond strength was determined. Of the three primers, both the Alloy Primer (33.3 MPa) and Estenia Opaque Primer (33.9 MPa) materials exhibited far better post-thermocycling bond strength than V-Primer (0 MPa). It can be concluded that the phosphate MDP is effective, whereas the thione VTD is ineffective for bonding SUS XM27 steel.

The aim of the current study was to evaluate the influence of polycarboxylate temporary cement remaining on the dentin surface on the bond strength of a composite luting system. An acrylic resin plate was luted to bovine dentin with a polycarboxylate temporary cement (HY-Bond Temporary Cement Hard, HYB). The temporary cement was not used for the control groups. After removing the temporary cement with an excavator, dentin specimens were divided into five groups; 1) no subsequent treatment, 2) cleaning with a rotational brush (RTB), 3) cleaning with a rotational brush and non-fluoridated flour of pumice, 4) sweeping with an air scaler, and 5) treated with a sonic toothbrush. A silane-treated ceramic disk (IPS Empress) was bonded to each dentin specimen with a composite luting system (Panavia F). Shear testing results showed that the RTB groups exhibited the highest bond strength regardless of the use of temporary cement (P < 0.05). The use of a rotational brush with water coolant is recommended to achieve ideal bond strength between the Panavia F luting system and dentin to which HYB temporary cement was primarily applied.

The purpose of this study was to evaluate the effect of acidic primers on bonding magnetic steel alloys. Three alloys (XM27, 447J1, and AUM20) were primed with one of the following materials: Acryl Bond, Estenia Opaque Primer, Eye Sight Opaque Primer, M. L. Primer, or Super-Bond liquid. The specimens were bonded with a tri-n-butylborane initiated resin, and bond strength was determined both before and after thermocycling in water. Unprimed specimen was considered as the control. Average bond strength varied from 0 to 45.3 MPa for the XM27 alloy, 0.3 to 43.6 MPa for the 447J1 alloy, and 0.5 to 41.1 MPa for the AUM20 alloy. Of the five primers, Estenia Opaque Primer exhibited better adhesive performance than the other materials regardless of the type of steel alloy. It can be concluded that the use of the Estenia Opaque Primer, which contains an adhesive monomer (10-methacryloyloxydecyl dihydrogen phosphate; MDP), is recommended for bonding the three magnetic steel alloys with TBB-initiated resin.
