Abstract
In the case of single tooth replacement, a fixed prosthesis or a dental implant is the treatment option commonly selected as first choice. However, any amount of sound tooth structure should be removed to prepare the abutment teeth for full coverage retainer. The adjacent tooth damage can be avoided placing a dental implant. However, depending on the patient's oral condition and any other circumstances, it may be impossible or delayed. In this case resin bonded fixed partial denture was selected as an alternative that can restore single tooth loss without much tooth structure removal to the young patients and the patients with gingival recession. We report these patients were satisfied with esthetic and function.

Fig. 6
After tooth preparation. Retention grooves are extended to incisal edge to maximize tooth coverage; selection of tooth colored zirconia minimizes esthetic complication. (A) Intraoral view, (B) Master cast.

Surveyed master cast. (A) Palatal view, (B) Mesial view of left maxillary first molar. Notice the high placed height of contour on proximal and buccal surfaces.
Fig. 9
After tooth preparation. Proximal and buccal surfaces were adjusted to relocate height of contour.

Intraoral view after prosthodontic treatment. (A) Occlusal view, (B) Frontal view. Metal retainer is extended to distobuccal line angle of left maxillary first premolar, but it does not compromise appearance.
