Design outcomes

Primary

MeasureTime frame
Measured using visual inspection at one month, 6 months, one year, two years: 1. Prothesis fracture: no fracture/color change or small fracture/zirconia fracture/complete fracture in the prosthesis 2. Marginal fit: complete fit/there is evidence of leakage/the probe can access the prothesis/prothesis is movable 3. Discoloration: no discoloration/surface discoloration/discoloration towards the pulb

Secondary

MeasureTime frame
Oral health index collected using oral examination and with UNC15 probe (university of North Carolina). Oral data collected from each patient on three different time intervals (after one month, after 6 months, after one year, after two years) 1. Plaque index (PI) 2. Gingival index (GI) 3. Decayed, missing, filled teeth index
