Prosthetic rehabilitation of mandibular defects with fixed-removable partial denture prosthesis using precision attachment: A twin case report

Abstract

The restoration of normal function and esthetic appearance with a dental prosthesis is a major challenge in the rehabilitation of patients who have lost their teeth and surrounding bone because of surgery for oral cyst or tumor. Rehabilitation with fixed or removable prosthesis is even more challenging when the edentulous span is long and the ridge is defective. Anatomic deformities and unfavorable biomechanics encountered in the region of resection add to the misery. In such situation, a fixed-removable prosthesis allows favorable biomechanical stress distribution along with restoration of esthetics, phonetics, comfort, hygiene, and better postoperative care and maintenance. This article describes rehabilitation of two cases with mandibular defects with an attachment-retained fixed-removable hybrid prosthesis.

Treatment Outcomes Based on Patient’s Oral Health Related Quality of Life (OHRQoL) after Receiving Conventional Clasp or Precision Attachment Removable Partial Dentures in Distal Extension Cases: A Randomized Controlled Clinical Trial

“…OT Cap attachment was used as it is simple and effective extra-coronal attachment designed for removable partial denture. The attachment has several advantages which preserves the abutment teeth and supporting structures in addition to patient satisfaction [14][15][16].…”

Knowledge and Awareness of Precision Attachments among Dental Students

“…(1) further tooth reduction; and (2) at least 3 mm of height are required. (Meşe and Özdemir, 2008;Munot et al, 2017) If extra coronal durable attachments are used for RPD, there is sometimes a lack of attachment space so that a denture tooth cannot be positioned over that. Also, the tiny commercial attachments available on the market use a great deal of edentulous space behind the abutment tooth.…”

Comparison between Integrated and Parallel Interlock Designs of an Extracoronal Attachment-retained Distal Extension Removable Partial Dentures

“…[ 12 ] In addition, they make the process of oral hygiene and plaque control more difficult. [ 13 14 ] On the contrary, extra-coronal resilient attachments may not provide sufficient reciprocation due to their resiliency. So, they necessitate the incorporation of a reciprocal component in the design of the RPD.…”
