The form of the mandibular anterior lingual alveolar process in partially edentulous patients

One hundred adult patients needing a Class I mandibular removable partial denture were selected to determine the incidence and prevalence of the form of the mandibular anterior lingual alveolar process. The processes ranged between 2 and 22 mm in height and from 37 ° to 125 ° angulations in relation to the occlusal plane. Shapes were found to be sloped (45), vertical (38), and undercut (17). The large variety of sizes and shapes of the lingual alveolar process stresses the importance of a precise impression technique to accurately register the anterior lingual alveolar process. Instructions to the dental laboratory for the design of the proper major connector for each specific situation will improve the quality of the removable partial denture service to the patient.
