Abstract
ABSTRACTBackground: Complete denture wearers show lower levels of bite force than dentate subjects. This has a significantinfluence on their chewing efficiency. In this study an attempt was made to investigate the effect of the impressiontechnique on the maximum bite force in complete denture wearers.Materials and methods: The patients selected for this research were 12 edentulous patients. Three differenttechniques for registering the final impression were made; the mucostatic, mucofunctional, and the selectivepressure impression technique. Two sets of upper and lower denture bases and one set of upper and lower dentureswere constructed for each subject. Intraoral and extraoral instruments and devices, as well as a computer programwere used for measuring the maximum bite force.Results: The subjects without past experience with complete dentures were able to give higher levels of bite forcewith dentures or denture bases constructed from the mucofunctional impression technique, while those with previousdentures gave higher levels of bite force with the dentures or denture bases constructed from the selective pressureimpression technique.Conclusions: It is recommended that dentures constructed from the mucofunctional impression technique be usedfor those subjects without previous experience with complete dentures, while for those with previous completedentures the selective pressure impression technique should be used.Key words: Maximum bite force, Impression technique, gnathodynamometer (J Bagh Coll Dentistry 2010;22(3):13-17).
