Abstract

This study aims to present the dynamic UCLA as a prosthetic option to restore a tilted implant, replacing a missing maxillary left lateral incisor with a functional and aesthetic screw-retained crown. Dental implants show high success rates; however, complications related to three-dimensional positioning of the implant are common. The correction of the implant position usually requires machined angled abutments or complex surgical procedures, which results in long and difficult treatment, and increases the treatment final cost. A 45-years-old male patient sought for specialized dental care to restore the front missing tooth esthetic area. The patient has limited mouth opening, mental and physical disabilities, so the construction of a metal-ceramic prosthesis with the aid of dynamic UCLA was proposed as a straightforward and low-cost procedure under the sign of free and informed consent. The prosthetic treatment provided aesthetic results and patient satisfaction without complications after a four-year follow-up.

Highlights

The use and acceptance of dental implants have improved and expanded treatment alternatives for fixed and removable dental prosthesis (Sripathi & Bhat, 2015)
This study aims to present the dynamic Universal Castable Long Abutment (UCLA) as a prosthetic option to restore a tilted implant, replacing a missing maxillary left lateral incisor with a functional and aesthetic screw-retained crown
The relationship between the threedimensional position of implants and restorations must be based on the implant neck and this relationship is important for a healthy self-response of hard and soft tissues (Buser et al, 2004)

Summary

Introduction

The use and acceptance of dental implants have improved and expanded treatment alternatives for fixed and removable dental prosthesis (Sripathi & Bhat, 2015). Clinical success and outcomes of implants are well documented in the scientific literature Alongside this successful story there are complications (Camargos et al, 2012) that challenge the prosthodontist to meet patient expectations (Chatterjee et al, 2015; Giannakopoulos et al, 2017). These complications are due to poor planning and poor communication between surgeon and prosthodontists, which might result in a common and avoidable complication: the three-dimensional implant positioning error (Chatterjee et al, 2015). Some surgical procedures have been proposed with the main technical objective of repositioning a bone segment together with an osseointegrated implant (Silva et al, 2005)
