Pink and white esthetic scores of polymer-infiltrated-ceramic-network and lithium disilicate implant hybrid abutment crowns: Randomized clinical trial

Patient satisfaction of vita enamic versus lithium disilcate hybrid abutment crowns in implants placed in the anterior zone

“…Comparison between group I & II regarding Q1, Q2, Q3 & Q4 was performed by using Independent t-test which revealed in significant difference in all as presented in table (5) and figure (5). Also, comparison between them regarding Q 5 was performed by using Chi square test which revealed absolute insignificant difference regarding yes answers as P=1.00, as presented in table (6) and figure…”

“…To combine the advantages of both ceramics with its high chemical stability, good mechanical and optical properties as well as excellent biocompatibility and composites having the advantageous elastic modulus similar to dentin, it was thought that combining them would result in an ideal restorative material that provides long-term esthetics. The manufacturer claimed that the use of such material may decrease the load transmitted to bone in attempt to decrease the crestal bone loss and increase the patient satisfaction as well (5) (6) Implant dentistry is always improving in relation to materials and surgical procedures in the last few decades, concentrating more on improving patient oriented results. At first, success and survival of dental implants was only measured by the phenomenon of osseo-integration by alberkston criteria as a rule for analyzing success rates.…”
