Modified zirconia-bonded M-bridge for prosthetic rehabilitation of missing anterior tooth in a young adolescent

Abstract

A space in the maxillary anterior region of the dental arch can produce a huge psychological impact on the young patient due to the unesthetic appearance of the teeth, necessitating immediate care for esthetic and functional rehabilitation. Trauma due to avulsion accounts for 0.5%–16% of all traumatic dental injuries to permanent dentition. Despite the availability of a variety of therapeutic treatments, including implants and removable partial dentures, these solutions have several drawbacks. Challenges range from poor wear compliance, growth disruption when used on young patients, and the inability to endure strong masticatory stresses. For the replacement of a missing tooth, resin-bonded bridges offer a minimally invasive, practical, cost-effective, and time-saving alternative. Maryland bridge is a type of resin-bonded bridge, the simplest, and most popular due to its micromechanical retention property. However, its disadvantages include esthetically unappealing and dislodgment of the prosthesis. Therefore, modifications may be introduced in the design of the bridge to address these limitations. The present case report illustrates a clinical case of prosthetic rehabilitation in a young patient utilizing modified zirconia-bonded M-bridge in conjunction with additional structural changes and can be considered as highly reliable early rehabilitation.
