“…Chemical etch applications (methyl methacrylate monomer, chloroform, acetone, ethylene chloride, ethyl acetate, dichloromethane) may change the morphology and chemical properties of the materials. [17][18][19][20][21][22][23] Commonly methyl methacrylate monomer chemical agent is used to increase bond strength of denture tooth retention. Some authors obtained that wetting the ridge-lap surface with methyl methacrylate monomer increased bond strength between denture tooth and acrylic resin.…”

SUMMARY Aim:The purpose of study is to assess the tensile strength between porcelain teeth and two different denture base (polyamide and heat-polymerized acrylic), a repair material (auto-polymerizing acrylic) after different types of surface treatment. Materials and Methods: Total of 63 same form and color mandibular right first molar porcelain denture teeth were used. The first molar porcelain denture teeth were separated into 3 material groups; Group 1: Heat-polymerized (HP), Group 2: Autopolymerizing (AP), and Group 3: Polyamide (PA) (n=21). Then, all material groups were divided into 3 subgroups (n=7) representing different surface treatment method; Control, Airborne abrasion, Er: YAG laser. A universal testing machine was used for determining the tensile bond strength (MPa) of the porcelain denture teeth to surface treated denture base and repair materials. The crosshead speed was set of 0.5 mm/min. Two-way ANOVA and post-hoc Tukey's HSD was used for statically analyses (α=0.05). The effects of the surface treatment were observed by scanning electron microscopy (SEM). Results: The polyamide (PA) has significantly higher (p< 0.05) tensile bond strength than the Heat-polymerized (HP) and Auto-polymerizing acrylic (AP). Polyamide (PA) with laser surface treatment (9.89 MPa) showed highest tensile bond strength. The lowest tensile bond strength was determined control group (6.38 MPa) of auto-polymerizing (AP). Surface treatments showed no significant difference. Conclusion: Superior tensile strength was found polyamide denture base and different surface treatments not affect the tensile strength of porcelain teeth.

Background: Soft lining materials play an important role in modern prosthodontics because of their capability of restoring health of inflamed and distorted mucosa. Gradual changes of oral tissues require that complete or partial dentures be relined to improve their adaptation to the supporting tissue. This study aimed to evaluate the shear bond strength (SBS) of heat cured acrylic and injection-molded Valplast TM denture base materials to silicone self-cure soft lining materials, with and without adhesive, after storage in two different times in artificial saliva. Materials and Methods: 40 rectangular specimens were prepared from two types of self-cured silicone soft lining material, one with adhesive and the other without adhesive were applied to two types of denture base materials ( heat polymerized Polymethyl methacrylate and injection-molded nylon denture base materials). Shear bond strength of the specimens was measured, after immersion in artificial saliva for different periods (72 hours or 10 weeks), using Lloyd universal testing machine. Results: Acrylic denture base bonded to soft liner with adhesive at 72 hours of immersion in artificial saliva showed the highest shear bond strength.Comparing SBS values of the tested soft lining materials revealed significant differences between adhesively bonded and non-adhesively bonded types. Conclusions: This study concluded that the bond strength of the silicone soft lining materials with denture base materials increased with adhesive. Silicone soft lining materials are affected by artificial saliva storage. INTRODUCTIONA major objective in construction of complete dentures is to attain a denture base that conforms to the supporting tissues with a high degree of accuracy. So, the greater the accuracy of the base, the more stable is the prosthesis and the more the comfortable of the patient. As a result of the changes occurring in the oral tissues under complete or partial dentures, periodic relining of that prosthesis is needed to improve their adaptation to the supporting tissue [1] .Codex : 10/1604 dentaljournal.forgirls@yahoo.com KEYWORDS

“…The mechanical properties of the artificial tooth and the adhesive agents and the bond strength between the tooth substance and artificial teeth are considered insufficient for long-term use, although the reliability of the properties of each material has been reported. [2][3][4][5][6][7][8][9][10] However, the DBFPDP technique is based on the concept of minimal intervention since it can conserve the enamel of the abutment teeth. The DBFPDP is a useful prosthetic method when it is reinforced with additional materials.…”
