Abstract Complete denture must fulfill one of the most important requirement of its success, which is harmonious function that develops by assuring harmony of occlusal contact in centric and eccentric maxillomandibular relations. So the search for the ideal occlusal scheme that maximizes denture stability, comfort, esthetics and maintains masticatory function has occupied the dental literature for many years and stills continues to do so, as the maintenance of masticatory function is important especially for patients wearing complete dentures due to their limitations. This study was conducted on twenty completely edentulous patients selected from Prosthodontic Department, Faculty of dentistry,Alexandria University. All patients were selected with well formed ridges and adequate interridge distances. Also, they had experience of previous one or more dentures before starting the study. Acrylic complete denture was constructed for each patient taking into consideration to apply bilateral balanced occlusion and canine guidance occlusion concepts for each patient. Patients were divided randomly to one of the treatment groups. Group(I) included ten patients who started by bilateral balanced occlusal concept and then after one month converted to canine guidance occlusion, while group(II) included the remaining ten patients who started by canine guidance concept then after one month converted to bilateral balanced occlusion. Then each denture was evaluated at different follow up periods of denture use (after one month of using the first occlusal concept, another month after changing the occlusal concept and finally after the following two months of using the final concept) through: i. Masticatory efficiency (chewing strength) by measuring mean concentration of the test dye using nanometer spectrophotometer at Central Laboratory of the Faculty of Pharmacy, Alexandria University. ii. General patient satisfaction by a questionnaire. The results of this study revealed that: |
