Rehabilitation of Edentulous Maxilla With Implant-Supported Bar Overdenture- A Case Report

Abstract

Dental implants have an important role in treatment of edentulous patients. Implantsupported overdentures are the primary treatment modality in cases presenting resorbed posterior maxilla with no available bone for implant placement. They have the advantages of increasing retention and stability of the denture, restoring the decreased labial and buccal support, recovering the appropriate occlusal dimension and improving the esthetics. Bars, balls and locators are used for retention in maxillary overdentures. However, bar retainers are the primary attachment system for patients having a few number of implants or implants not paralel to each other since they connect the implants and provide a unique path of insertion. This report describes the rehabilitation of a patient with maxillary implant-supported CAD/CAM milled-bar overdenture to provide splinting of implants.

Tam Dişsiz Maksillanın Bar Tutuculu İmplant Destekli Overdenture İle Rehabilitasyonu- Olgu Raporu

Abstract

Dental implantlar tam dişsiz hastaların tedavilerinde önemli bir role sahiptir. Posterior maksiller bölgede kemik hacminin azaldığı ve çok sayıda implant yerleştirmeye elverişli olmadığı olgularda, protezin tutuculuğunun ve stabilitesinin artırılması, uygun yüz yüksekliğinin oluşturulması ve dudak, yanak gibi dokuların desteklenerek estetiğin geliştirilmesi gibi avantajlarından dolayı implant destekli overdenture protezler uygun bir tedavi seçeneğidir. Maksiller overdenture protezlerde tutucu olarak bar, top başlı ve locator tutucular kullanılabilmektedir. Az sayıda ve paralel olmayan implantların olduğu durumlarda implantların birleştirilmesi ve paralel bir giriş yolu sağlanabilmesi nedeniyle ilk tercih edilmesi gereken tutucular bar tutuculardır. Bu olgu raporunda üst çenesi tam dişsiz bir hastanın CAD/CAM ile üretilmiş bar tutuculu overdenture ile rehabilitasyonu anlatılmaktadır
