The roots of the second molar are less divergent and less curved than those of the first. • The third molar consists of four or more cusps. • The mesial crown margin of the third molar may have a contact area showing interproximal wear whereas the distal margin would not. • The ...
Each subject chewed a piece of chewing gum on the molars of the treated side before and after crown placement. Movement trajectory was recorded using the Sirognathograph Analyzing System. Normalized jerk-cost (NJC) was calculated on the closing phase of each chewing cycle and was compared ...
After appropriatelocal anestheticblocks, anincisionis made along the cervical areas of the first molar along the external oblique ridge. A full-thickness mucoperiosteal flap is elevated. A round bur is used to expose the crown of the impacted second molar and third molar. It is important to av...
9.Application of telescope crown denture in occlusal rehabilitation for patients with serious residual tooth attrition应用套筒冠义齿对牙列缺损伴余留牙重度磨耗进行 重建 10.The Clinical Evaluation of Indirect Composite Inlay/Onlay Restoration for Children's Molar and Relevant Study;复合树脂嵌体修复儿童磨牙缺...
The upper arch was scanned with a 3D intraoral scanner immediately (baseline), 6 months, and 1 year after crown cementation to evaluate the wear of the natural enamel of the antagonistic primary molar. The resultant scans were compared via Exocad software to measure the amount of linear wear ...
Different studies highlight a phenomenon of root migration toward the crown. Leung et al. (2009) note a migration of 3.06 mm (±1.67 mm) after 24 months with a migratory peak within the first 3 months, followed by a stabilization up to 36 months (13) (Fig. 7). These results ...
Triconodontidae are considered the first carnivorous crown mammals. A virtual reconstruction of the masticatory cycle in the Late Jurassic Priacodon showed that triconodontid dental function is characterized by precise cutting on elongated crests. The co
Whether it's a tough piece of steak or a mouthful of leafy greens, they are responsible for breaking down food before swallowing. In fact, they're the teeth most often in contact with food after that initial bite. Their large size paired with the jagged surface make them the workhorses ...
If extrusion of the maxillary second molar is a concern for the patient or doctor, then a crown on the mandibular first molar may include an occlusal contact with the mesial marginal ridge of the maxillary second molar, or the maxillary second molar may be bonded to the maxillary first molar...
Themaxillary first molarsare three rooted, two buccal and one palatal. The mesiobuccal root is broad in the buccopalatal plane and narrow in the mesiodistal plane, similar to a maxillary premolar root configuration. The root generally exits the crown mesially and can abruptly curve distally. The...
