Functional and Aesthetic Rehabilitation of Distal Extension Edentulous Arches with Extra-Coronal Attachments: A Clinical Case Utilizing the PreciVertix System

Rehabilitating Kennedy Class I and II cases, particularly when opposing a partially edentulous arch, presents notable challenges due to retention difficulties.While implant-supported prostheses are often the ideal solution, systemic health limitations can sometimes preclude their use.Conventional clasp-retained partial dentures provide an alternative, but they lack aesthetic appeal.In contrast, extra-coronal attachmentretained prostheses offer a more visually pleasing and accessible option.Despite the long-standing availability of dental attachments, their advantages remain underutilized in clinical practice.Attachments can significantly enhance comfort, aesthetics, functionality, and patient satisfaction, especially in cases of long-span edentulism where implants or fixed partial dentures are unsuitable.For patients with unilateral or bilateral posterior tooth loss, attachment-retained cast partial dentures provide a viable solution.Precision attachments are designed to balance stability and aesthetics while minimizing excessive forces on the abutment teeth and ridges during use.Semi-precision attachment systems are widely valued for their ability to provide stability, retention, and aesthetics in removable partial dentures, thereby enriching traditional treatment options.The present case demonstrates the use of an extra-coronal precision attachment (Preci-Vertix attachment system) to restore maxillary bilateral distal extension edentulous spans.
