Modified Nance palatal arch appliance for anterior tooth replacement

Abstract

SUMMARYThe following case report presents a new and an innovative technique for the postextraction replacement of maxillary central incisors using the natural teeth as pontics. The novel appliance fabricated fully satisfied the demands of the adolescent patient for a fixed prosthetic, while fulfilling the aesthetic and functional requirements presented by the case. BACKGROUND

Rehabilitation of a Child with Denari Prosthesis after Dental Avulsion

“…Although the literature refers to a series of fixed devices to be used in similar cases to the one above drafted [10], such as fixed prostheses with orthodontic bands, fixed prostheses with precision attachments, and the Nance button, among others [11], with advantages associated with a minimum dental preparation, easy repair, and absence of the possibility of damaging periodontal tissues [12], these require a simultaneous modification with the growth and development of the premaxilla in a transverse direction, which triggers a constant replacement of these devices [16]. The prosthetic design, based on the tube-bar system, which characterizes this prosthesis, in addition to being readily accepted by the patient, guarantees minimal repercussion of soft and hard tissues, thus achieving adequate and correct occlusion, without interfering with growth maxillary transverse [13,17]. This outcome was evidenced in our patient, in whom an increase in the interincisal spacing was observed as a result of transverse maxillary growth, which is the rationale of using this appliance type.…”
