Restoring Congenitally Missing Maxillary Lateral Incisors Using Zirconia‐Based Resin Bonded Prostheses

Abstract

The zirconia-based resin-bonded prosthesis constitutes a viable and conservative treatment modality for the replacement of missing teeth either congenitally or from another etiology in young patients in which implant therapy and a fixed partial denture are currently contraindicated.

Clinical procedures, designs, and survival rates of all‐ceramic resin‐bonded fixed dental prostheses in the anterior region: A systematic review

“…Also, oscillating handpiece with diamond tips can be used for the preparation of the abutment teeth with the use of a dental operating microscope . Prior to final impression, a control impression might be done to verify the proper path of insertion …”

“…The matrix of the duplicate cast of the wax‐up can be used with dual‐cure bis‐acryl material for the fabrication of the provisional restorations. After contouring, finishing, and polishing of the provisional restoration, it is bonded to the palatal surfaces of the abutment teeth with a spot‐etch and bonding technique . Also, provisionalization can be done with a composite tooth fixed on the buccal surfaces of the abutment teeth with an orthodontic wire and dental composite, so the prepared dental surfaces are not used and kept untouched as they are reproduced in the dental impression …”

“…For the cantilever design RBFDPs, a small extra wing might be fabricated on the framework to facilitate the correct placement during try‐in . Ovate pontic design might be chosen to achieve more esthetic results in the definitive RBFDPs …”

“…So, if there is a group function articulation, then the two lingual retainer design might be considered as a treatment alternative. If there are relatively short clinical crowns of the abutment teeth and bonding surface is very limited, than two lingual retainer design might be preferred …”

Congenitally missing primary and permanent maxillary lateral incisors

“…A number of therapeutic options are available, including removable partial dentures, fixed prosthodontics, resin-bonded bridges or implants in association with prosthetics crown. Recently, an alternative treatment modality has been reported in which a zirconia-based resin-bonded prosthesis is used to restore congenitally missing maxillary lateral incisors 13. Fibre-reinforced composite bridge also offers a good treatment alternative to conventional treatment options for replacement of permanent anterior teeth until a more definitive treatment can be planned 14.…”
