AIM This study is to evaluate the role of 1:1 v/v 30% trichloromethane and monomer solvent in enhancing the durability of bonding between cross-linked acrylic teeth and different heatcured denture bases with or without mechanical preparations made on ridge lap portion of the artificial teeth. MATERIALS AND METHODS Two high impact denture base resin materials (Trevalon HI, DeTrey, UK, and DPI ...

An accurate transfer of the inter-occlusal relationship to the articula-tor is essential for the fabrication of a prosthesis. 1 The accurate articulation of working casts results in less time spent adjusting occlusion. This has a direct effect on the quality of the restoration and the operational cost of treatment. 2 Therefore, an ideal registration material and technique combination would allo...

OBJECTIVES The aim of this study was to introduce modified continuous wave compaction (MCWC) technique and compare its obturation quality with that of lateral compaction (LC), warm vertical compaction (WVC) and continuous wave compaction techniques (CWC). The obturation time was also compared among the four techniques. MATERIALS AND METHODS Sixty-four single-rooted teeth with 0-5° root canal ...

Acrylics are compounds polymerized from monomers of acrylic, metacrylic acid or acrylonitrates. The purpose of this paper is to present the technology and use of acrylics for provisional dentine protection in the practice of dental prosthodontics. For this reason, we followed 120 clinical cases from the everyday clinical practice, divided into 4 groups of 30 patients who needed prosthetic recon...

Crossliked plastic denture teeth have been used clinicaly in order to improve the poor wear resistance of conventional acrylic denture teeth. We suggest that highly crosslinked denture teeth are possibly disadvantaged compared with conventional ones, when considering the adhesion to denture base and impact resistance. The purpose of this study is to evaluate the impact resistance of crosslinked...

Acrylic processing of waxed-up dentures is considered to be a crucial and technique-sensitive procedure. Polymethylmethacrylate (PMMA) has become the most commonly used material for denture bases since its introduction in 1937. The advantages of PMMA include excellent esthetic properties, adequate strength, low water sorption, low solubility, lack of toxicity, facility of repair, and constructi...

the aim of this study was to introduce modified continuous wave compaction (mcwc) technique and compare its obturation quality with that of lateral compaction (lc), warm vertical compaction (wvc) and continuous wave compaction techniques (cwc). the obturation time was also compared among the four techniques.sixty-four single-rooted teeth with 0-5° root canal curve and 64 artificially created ro...

Data dealing with successful or unsuccessful acrylic tooth implants have accumulated gradually during the past 20 years. Flohr' studied plastic material as a possible substitute for natural teeth by placing screw-type acrylic roots into surgically created alveolar sockets. He reported that normal connective tissue formed against the acrylic, and only minimal infiltration occurred. Hodosh, et al...

The assessment and reestablishment of the occlusal vertical dimension (OVD) are considered important factors in the treatment of complete denture wearers. The long-time use of a complete denture can result in jaw displacement due to abrasion of the artificial teeth and residual ridge resorption, causing esthetic complications. Most patients with old dentures and incorrect OVD accept reestablish...
