Study Description

Examination and diagnosis: Selection and examination of the patients according to inclusion and exclusion criteria. Diagnosis of the patient's chief complaint and teeth that will be involved in this study will be done.

Primary alginate impressions for diagnosis on primary casts and for mounting. The patients will be asked to maintain good oral hygiene measures by using tooth brush twice daily.

Taking a professional pre-operative photo.

Tooth preparation procedure:

  1. Preparation of abutment tooth for Resin bonded fixed partial denture according to specific standardized design for both types of final restorations.

  2. After tooth preparation, the final impression will be taken for each participant using the intraoral scanner.

  3. Fabrication of temporary restoration using composite resin temporary material and cemented using Zinc Oxide eugenol free temporary cement.

Fabrication of final restoration:

Lithium Di-silicate or Zirconia Resin bonded fixed partial denture will be fabricated according to group.

Clinical assessment and survival evaluation of the final restoration on delivery and on follow-up every 12 weeks for 12 months following outcome measures.
