INADEQUATE TOOTH PREPARATION
If the tooth is abraded without the step-stair bevel and precise preparation line, the crown cannot be made precisely and it is not applied on the tooth properly. Unfortunately, this is still a relatively common case.
We consider such works to be poor, worthless prosthetic work. This kind of bad practice is often the source of patients’ fear of dental crowns which is why they postpone prosthetic treatment, thus resulting in additional loss of dental units.
In this case, the edge of the crown is thicker than the tooth root, which creates a gap in-between them.
In such a gap, food is retained, forming deposits that can’t be cleaned even with the best kind of hygiene, hence accumulating bacteria that can cause chronic gum inflammation which then spreads further towards the bone around the tooth and other parts of the periodontal structures, causing periodontitis. The detached edges of the crown also apply mechanical pressure on the gums, which further aggravates the situation.
All of these factors cause constant bleeding and discolouration of the gums that acquire a bluish or darker shades of purple. Also, a dark edge around the metal ceramic crown appears.
In these cases, the ceramic crown is usually considerably thicker than the natural crown, as it once was, which can cause major disfunctions in the chewing system.
The result is a very poor aesthetic appearance, both of the gums and the teeth,
as well as the area around the dental crown.
Fortunately, when such poor prosthetics are removed from the oral cavity, professional cleaning and periodontal treatment are performed, high-quality aesthetic crowns or bridges are created - the gums recover, they stop bleeding and restore its beautiful pink colour as well as a nice and harmonious relation with new aesthetic and functionally adequate ceramic crown.
