A Comparative Evaluation of Lateral Condylar Guidance by Clinical and Radiographic Methods - Hanau's Formula Revisited.

Background: Various clinical methods for recording the condylar guidance (CG) are the intraoral check bite method, graphic tracings, and functional recordings. Accuracy of graphic tracings is affected by patient-related factors such as neuromuscular control of the individual, stability of record bases as well as stability of recording media. The current recommended average settings using Hanau's formula questionable, and thus reassessment is needed.

Evaluation of Cytotoxicity of Heat-cure Denture Base Resin Processed with a Dual-reactive Cycloaliphatic Monomer.

Aim: The aim of this study is to evaluate cytotoxicity of tricyclodecane dimethanol diacrylate (TCDDMDA) when added to conventional heat-cure methyl methacrylate (MMA) monomer at 10% and 20% (v/v) concentrations.

Materials And Methods: Twenty seven disk-shaped processed specimens were divided into control group ( = 9; comprises specimens made without substituting TCDDMDA in MMA) and two experimental groups ( = 9 each; specimens prepared by substituting TCDDMDA in MMA at 10% and 20% (v/v) concentration). Eluates were prepared by placing three specimens of each group into 9 mL of culture medium and then incubated at 37ºC for 24 hours.

Impact Strength and Dimensional Accuracy of Heat-Cure Denture Base Resin Reinforced With ZrO Nanoparticles: An Study.

Background: Polymerization shrinkage and fracture are the two common trouble shoots with denture base resins. Polymerization shrinkage affects the dimensional accuracy and fit of the prosthesis. The effect of zirconia (ZrO) nanoparticles on polymerization shrinkage is not documented yet.

Effect of Surface Modifications on the Retention of Cement-retained Implant Crowns under Fatigue Loads: An Study.

Background: Masticatory forces cause fatigue to the dental luting agents, adversely affecting the retention of these cement-retained crowns. Sandblasting (SB) and diamond abrading the abutment surface improves the bond strength of luting agents. However, the effect of acid etching (AE) on the implant abutment surface and the effect of other surface modifications under masticatory load are yet to be documented.

A simple method of enhancing retention in interim hollow bulb obturator in a case of an acquired palatal defect.

Maxillary defects occur either as a result of surgical resection of malignant tumors of the nasal cavity and paranasal sinuses or of the congenital causes. Rehabilitation of the patients with maxillectomy defects presents a challenge in restoring the lost form, function and speech. Maxillary interim obturators in prosthetic reconstruction of the defects are often complicated with lack of adequate retention, stability, and support.
