Comparison of Different Final Impression Techniques and Occlusal Schemes for Management of Resorbed Mandibular Ridge: A Case Report

Gross mandibular atrophy has been described as a multifactorial biomechanical disease resulting from a combination of anatomic, metabolic and mechanical determinants varying with time from patient to patient in an infinite number of combinations. The history of complete denture impression procedures has been influenced largely by the development of impression materials from which new techniques and ideas arose. The purpose of this study was to compare the retention of complete dentures made by using two different impression techniques like all green and functional techniques and further comparison of two different occlusal schemes i. e. lingualized balanced occlusion and monoplane occlusion scheme. The results showed that there was significant difference in retention between the two techniques where functional technique showed the highest mean value of retention followed by all green. However, on clinical examination, the retention produced by both the techniques was satisfactory. Patient experienced better chewing efficiency and comfort with lingualized balanced occlusion denture.
