Attachment Retained Tooth Supported Overdentures: A Case Series

Abstract

Present case series describes the three different types of attachments use for tooth supported overdenture for prosthetic rehabilitation. Loss of teeth causes continuous resorption of the bone leading to a compromised treatment. Retaining two or more natural teeth can be used as an abutment for prosthetic rehabilitation of partial edentulism arches. Preventive prosthodontics includes tooth supported overdentures which preserves natural teeth, roots and maintains propioception. Depending upon the interarch distance available various types of attachments can be used to enhance the retentive factors. The first case (71-year-old female patient) describes the use of telescopic attachment overdenture on 33, 43 with available interarch space of 15 mm in mandibular arch. The second case (62-year-old female patient) describes the use of ball attachments overdenture on 34 and 35 with available interarch space of 13 mm in mandibular arch. The third case (60-year-old female patient) is about equator attachment overdenture on 33, 43 with available interarch space of 12 mm in mandibular arch. Use of telescopic, ball and equator attachments for tooth supported overdentures has enhanced the retention, stability, function and aesthetic outcome of the removable prosthesis in mandibular arch. The natural teeth provide additional support, stability and retention of the overdenture than the edentulous ridges alone which is particularly advantageous for mandibular arch.
