The aim of this study is to evaluate the influence of superstructure material on crestal bone resorption and esthetic outcome of dental implants in patients with single missing tooth in the aesthetic zone.
The transfer of occlusal forces to the implant bone interface greatly influence the long term prognosis of implants and crestal bone resorption. Accordingly this study will investigate the influence of metal ceramic crowns and monolithic zirconia crowns on crestal bone resorption under loading. Also these crown materials greatly influence the final aesthetic outcome of the definitive restoration, which will be evaluated using the pink and white aesthetic scoring systems.

The objective of this study was to compare the 5-year survival and clinical behavior of single posterior ceramic crowns made with pressable ceramic on zirconia or on a metal framework. If ...
The objectives of this study are to determine the clinical performance of zirconia-based dental prostheses and their related properties.
To assess and compare the esthetic outcome and clinical performance of anterior maxillary all ceramic implant single crowns based either on prefabricated zirconia abutment veneered with pr...
In patients receiving implants in the esthetic zone, would the use of new Nano hybrid ceramic crown material (Crystal Ultra) improve esthetic patient satisfaction and peri-implant tissue s...
This study is designed to recall all patients who have received a full-arch monolithic zirconia implant supported fixed dental prosthesis in the University of North Carolina (UNC) School o...
To evaluate the resistance to axial forces of screw-retained monolithic high translucency zirconia (mHTZr) crowns compared with high translucency zirconia + feldspathic ceramic (HTZrC) crowns, low tra...
The aim of this study was to investigate and compare the marginal fit of posterior fixed dental prostheses (FDPs) made of monolithic and veneered computer-aided design/computer-assisted manufacture (C...
Crown ethers are well established as cointercalates in many layered hosts, but there are no reports of crown ethers incorporated into graphite. Here, we describe the preparation of the first graphite ...
The Eysenck Personality Questionnaire's (EPQ) N value (neuroticism) was used to evaluate information from 158 patients before ceramic crown treatment. Patient satisfaction was also evaluated using a s...
Crown ethers, discovered by the winner of the Nobel Prize Charles Pedersen, are cyclic chemical compounds that consist of a ring or multiple rings containing several ether groups that are capable of b...
The upper part of the tooth, which joins the lower part of the tooth (TOOTH ROOT) at the cervix (TOOTH CERVIX) at a line called the cementoenamel junction. The entire surface of the crown is covered with enamel which is thicker at the extremity and becomes progressively thinner toward the cervix. (From Jablonski, Dictionary of Dentistry, 1992, p216)
Technique combining controlled eruptive tooth movement and incision of the supracrestal gingival attachment to allow for proper restoration of a destroyed or damaged crown of a tooth. Controlled eruption of the tooth is obtained using ORTHODONTIC APPLIANCES. During this eruptive phase, repeated incisions are made at the junctional epithelium of the sulcus and the supracrestal connective tissue to prevent coronal displacement of the gingiva and of the attachment apparatus.
A prosthetic restoration that reproduces the entire surface anatomy of the visible natural crown of a tooth. It may be partial (covering three or more surfaces of a tooth) or complete (covering all surfaces). It is made of gold or other metal, porcelain, or resin.
Macrocyclic compounds analogous to CROWN ETHERS but which lack any OXYGEN atoms.
In utero measurement corresponding to the sitting height (crown to rump) of the fetus. Length is considered a more accurate criterion of the age of the fetus than is the weight. The average crown-rump length of the fetus at term is 36 cm. (From Williams Obstetrics, 18th ed, p91)
Osteoporosis is a disease in which the bones become extremely porous, are subject to fracture, and heal slowly, occurring especially in women following menopause and often leading to curvature of the spine from vertebral collapse. Follow and track&n...
