Abstract

<p>Patient: A 67-year-old female patient presented with the chief complaint of chewing difficulties due to poor retention of a mandibular complete overdenture. The mandibular residual ridge was resorbed and knife-edged. The existing overdenture was not well retained or stable due to the movement of |12 . Therefore, |12 was extracted, two implants were placed in the mandible, and an implant overdenture with a stud attachment was placed.</p><p>Discussion: Masticatory function was improved by using the form of the denture that had been worn to determine the placement of the implant and by fabricating a final denture with stud attachments to provide retention.</p><p>Conclusion: The placement of two implants and an implant overdenture in an edentulous patient with a mandibular knife-edge ridge showed good results.</p>
