If the tooth, because of its relative lack of exposed tooth structure, also requires crown lengthening, the total combined time, effort, and cost of the various procedures, together with the decreased prognosis because of the combined inherent failure rates of each procedure, might make it more reasonable to have the tooth extracted and opt to ...
Pivot tooth with a ferrule. The pivot tooth [1] [2] is a fixed dental prosthesis used to rebuild a tooth.It is a type of crown-root foundation [], but it is an independent supplement and usually consists of a pin or peg and a full crown [3] permanently connected (i.e., without cement) and placed in the patient's oral cavity during a single visit. [4]
Other treatments include restoration, where there is an overlay of material on the tooth to harden and make it a tooth-like structure. Even uncomplicated patients who show no strong effects can be recommended to undergo a crown restoration to be preventive and frequently x-rayed to stay updated on the condition of the tooth .
It can be identified as missing tooth structure and may manifest as pits or grooves in the crown of the affected teeth, and in extreme cases, some portions of the crown of the tooth may have no enamel, exposing the dentin. [2] It may be generalized across the dentition or localized to a few teeth. Defects are categorized by shape or location.
The dental papilla contains cells that develop into odontoblasts, which are dentin-forming cells. [3] Additionally, the junction between the dental papilla and inner enamel epithelium determines the crown shape of a tooth. [2] The dental follicle gives rise to three important entities: cementoblasts, osteoblasts, and fibroblasts. Cementoblasts ...
This circumferential collar should have a height of ~2 mm and width of ~1 mm. [16] Presence of adequate ferrule helps resist tooth fracture by minimizing stress concentration at the junction of tooth structure and the dental restoration. [17] This has been shown to significantly reduce the incidence of fracture in the endodontically treated ...
