Increased occlusal stability: teeth are less likely to drift, occlusal contacts are likely to be maintained etc. Increased success of restorations : excessive wear , fractures, cracks are less commonly observed where there is an ideal occlusion
The best instrument to use for this is a high-speed diamond fissure bur and the reduction should follow the inclination of the cusps and grooves as this will allow the preservation of more tooth tissue. A functional occlusal bevel should be created on the occlusal loading cusp of molar teeth by holding the bur at a 45 o angle to the occlusal ...
At that time, the dentists tried to use only hand instruments to open and/or enlarge small cavities and selectively remove the decayed tissue, followed by the placement of a glass ionomer cement, an adhesive filling that also releases fluoride and helps the tooth's "recovery" from decay (remineralisation). This treatment was tested in clinical ...
Composites and amalgam are used mainly for direct restoration. Composites can be made of color matching the tooth, and the surface can be polished after the filling procedure has been completed. Amalgam fillings expand with age, possibly cracking the tooth and requiring repair and filling replacement, but chance of leakage of filling is less.
In order to accept a stainless steel crown, the entire occlusal surface should be reduced by 1–1.5 mm and interproximally contacts should be cleared by cutting a thin mesial and distal portion or slice subgingivally by holding the tip of a thin high-speed bur at 15–20° relative to the long axis of the tooth, to avoid the creation of a ...
Occlusal trauma; Secondary occlusal trauma on X-ray film displays two lone-standing mandibular teeth, the lower left first premolar and canine. As the remnants of a once full complement of 16 lower teeth, these two teeth have been alone in opposing the forces associated with mastication for some time, as can be evidenced by the widened PDL surrounding the premolar.
In the dental specialty of endodontics, periradicular surgery is surgery to the external root surface. Examples of periradicular surgery include apicoectomy , root resection , repair of root perforation or resorption defects, removal of broken fragments of the tooth or a filling material, and exploratory surgery to look for root fractures.
A glass ionomer cement (GIC) is a dental restorative material used in dentistry as a filling material and luting cement, [1] including for orthodontic bracket attachment. [2] Glass-ionomer cements are based on the reaction of silicate glass-powder (calciumaluminofluorosilicate glass [ 3 ] ) and polyacrylic acid , an ionomer .
