Summary
Cerana ceramic restorations, utilizing leucite inserts, demonstrate excellent long-term clinical performance and retention. These single-visit restorations offer a viable, aesthetically pleasing alternative to traditional materials.
Area of Science:
- Dental Materials Science
- Restorative Dentistry
- Clinical Trials
Background:
- Single-visit ceramic restorations offer an alternative to resin-based materials.
- Leucite-reinforced ceramic inserts enhance composite restoration characteristics.
Purpose of the Study:
- To prospectively evaluate the long-term clinical performance and longevity of Cerana restorations.
- Assess the durability and clinical acceptability of Cerana restorations over an eight-year period.
Main Methods:
- Prospective clinical trial involving 33 Cerana restorations (25 Class I, 8 Class II).
- Utilized leucite inserts cemented with composite resin, assessed using modified USPHS criteria.
- Evaluated anatomical form, marginal adaptation, surface roughness, discoloration, color match, and retention up to eight years.
Main Results:
- High scores for anatomical form (94%) and marginal adaptation (61%) maintained at eight years.
- No significant marginal discoloration between insert and composite; minor discoloration at composite-tooth interface.
- All restorations demonstrated excellent retention and clinical acceptability, with minimal failures unrelated to the insert material.
Conclusions:
- Cerana restorations exhibit favorable long-term performance, aesthetics, and patient acceptance.
- The system is a suitable alternative for single-visit, tooth-colored restorations in appropriate cavity preparations.
- Leucite inserts contribute to the clinical success and durability of these ceramic restorations.

01:19Veneer
Veneer refers to a thin sheet of wood, typically produced to a thickness of about one-eighth of an inch or less. This material is crafted through various methods, the most common being rotary cutting. In this process, a log is mounted into a large lathe and spun against a knife edge, peeling off a continuous strip of wood as the knife penetrates deeper into the rotating log, creating a rotary-cut veneer.
Other veneering techniques include plain-slicing, quarter-slicing, and rift-slicing. These...

01:19Restorative Care
Restorative care is provided once a patient has been discharged from a healthcare facility and requires additional services. The additional services include home care, rehabilitation programs, and extended care. Restorative care centers help the patient regain their previous level of functioning or acquire a new level of functioning due to the incapacitating effects of a disease or a disability. It aims to assist patients in enhancing their quality of life by encouraging independence,...
