Immediate functional loading of implant-supported mandibular prostheses with customized UCLA'S attachments with distal extension: A case report.

ABSTRACT

Implant-supported complete dentures are a common procedure for patients with mandibular edentulism problems. This article documents the protocol for immediate functional loading of fixed transient mandibular prostheses with fully moldable attachments and distal extensions to prevent fractures. A 56-year-old female patient was referred to the Oral Rehabilitation and Implantology Service due to periodontal problems, difficulty in chewing capacity and aesthetic compromise. The patient was treated in a single surgical procedure with dental extractions, guided regularization of the alveolar process and guided placement of five interforaminal implants and placement of functional fixed mandibular prostheses with immediate loading with personalized UCLA'S, distal extensions and short arc occlusal scheme. At 3 months postoperatively, the definitive placement of fixed mandibular metal acrylic prostheses and conventional upper prostheses was performed. The functional and aesthetic integrity of the fixed mandibular prosthesis implant preserved with UCLA'S documents that implant placement in the interforaminal zone with an immediate loading protocol is a viable treatment option for prosthetic rehabilitation of the fully edentulous mandibular arch and that design with distal extensions in the posterior sector of the mandibular arch is an effective option to avoid fracture of the prostheses, presenting a survival of the five mandibular implants of 100% at 1 year postoperatively.
