The "DO" designation indicates that the gold serves as a restoration for the distal and occlusal surfaces of the tooth. This tooth was prepared and the inlay will be fabricated according to the R.V. Tucker method of gold inlay preparation. Notice how the line angles of the impression for the inlay are very sharp and precise; this is achieved ...
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
Tooth #3, the upper right first molar, has an MO (mesial-occlusal) gold inlay. This molar is both posterior, as well as distal, to the premolars in front of it. Most of the principal terms can be combined using their corresponding combining forms (such as mesio-for mesial and disto-for distal). They provide names for directions (vectors) and ...
They can be used in direct restorations to fill in the cavities created by dental caries and trauma, minor buildup for restoring tooth wear (non-carious tooth surface loss) and filling in small gaps between teeth (labial veneer). Dental composites are also used as indirect restoration to make crowns and inlays in the laboratory.
The occlusal surface has four grooves. The central groove is not straight but runs down the center of the tooth mesially to distally and contains four pits (mesial, central, central, and distal). The distobuccal groove runs from the distal pit in the central groove distobuccally separating the distal and distobuccal cusps.
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.
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 ...
To remove occlusal interferences, Schuyler, introduced the BU-LL and MU-DL rule. This included reduction of the buccal cusp in the upper teeth and the lingual cusp of lower teeth in the frontal plane. Additionally, on the sagittal plane reductions are made on the mesial cusp for upper teeth and distal cusp of the lower teeth.
