Abstract:
BACKGROUND:Occlusal scheme is the key of a successful complete denture, and how to choose a suitable occlusal scheme is a long-term problem for prosthodontists.
OBJECTIVE:To systematical y review the clinical effects of two occlusal schemes for complete denture.
METHODS:An electronic search of Cochrane Library, Medline/PubMed, EMBASE, CNKI, Wanfang and CBM databases were performed for clinical trials published before October 2013 using the key words of“complete denture”,“edentulous”,“occlusion”,”balanced”,“lingualized”,“anatomic”in Chinese and English. A manual searching of 11 relevant journals concerning oral medicine and reference lists of selected articles were conducted. Two reviewers independently extracted the data and assessed the quality of the included literature. Total y, 628 papers were retrieved.
RESULTS AND CONCLUSION:Only five articles met the inclusion and exclusion criteria. Of these five articles, one study showed lingualized occlusion dentures were more satisfactory than bilateral balanced occlusion dentures in denture retention (P<0.05);one study showed the lingualized occlusion exhibited lower scores for uncomfortable eating and avoiding particular foods (P<0.05), but higher scores for uncomfortable dentures than the bilateral balanced occlusion (P<0.05);one study showed the lingualized occlusion dentures have better masticatory efficiency and better protective role in alveolar bone than the bilateral balanced occlusion dentures (P<0.05);another two studies showed no significant differences in the overal satisfaction between lingualized occlusion and bilateral balanced occlusion dentures. These findings indicate that the lingualized occlusion is similar to bilateral balanced occlusion in the satisfaction of patients, masticatory efficiency, appearance and speech, but the lingualized occlusion dentures are better for severe alveolar bone resorption patients in terms of masticatory efficiency and better protection of alveolar bone.
