Bonded All Porcelain Crowns Go Back
(Possibly the most aesthetic crown of all)
By Dr Lawrence Spindel,

Bonded all procelain crown on patient's left central incisor.
Although I make many types of crowns, the most natural and aesthetic crown is an all porcelain crown, that is bonded to place. This is the optimum crown for most anterior teeth. Since it is just made of one material (feldspar porcelain), it does not require any opaquing to mask any coping material. If the patient’s natural tooth is essentially intact and sturdy and not overly dark, this crown can be fabricated in an extremely natural and translucent manner.
Think of them as a 360 degree porcelain laminate, requiring less reduction than any other type of comparable crown, and having the same natural qualities of a porcelain veneer. Because they are bonded to place, they are stronger than their predecessor, the original 'porcelain jacket' that was cemented with dental cements and notoriously fragile.
Many patients, especially the elderly, are not really ideal candidates for porcelain laminates. Porcelain laminates require enamel to bond to in order to be firmly attached to teeth. Many elderly patients with recession have no enamel on the exposed cervical areas of their teeth. Porcelain Veneers made on their teeth often have a greater likelihood of popping off. Because of the increased retentiveness allowed by a full crown preparation, bonded porcelain crowns do not require as much, if any enamel to attach to ant these restorations do not 'pop off'.
Cosmetic Dentistry Tip:
Brushing alone is usually not enough to ensure that a person won’t develop periodontal disease. Since 40% of a tooth’s surface is not reachable by tooth brushing, some sort of interproximal cleaning device should be used on a regular basis. Floss, Stimudents and small interproximal brushe , and all work well. It doesn’t matter as much which method is chosen, but what counts is that one of these is effectively used on a regular basis.
Regular and frequent professional cleaning at the dentist also help, since they remove any accumulations of plaque and tarter that have been missed by a patient by their daily homecare regime. Also a patients home care can be checked at frequent cleaning visits and the hygienist will encourage them to do better. Human nature being what it is, patients often perform their best home care immediately before and after their checkups.
