Analysis of Modification of Spur Gear Profile
, 2018 The article presents an analysis of the modification of the toothing of spur gears. The aim of the modification of the profile on the tooth tip is to compensate for the tooth deflection under loading and to improve the conditions of gear operation. Cases

The Anatomical Record, EarlyView.Abstract The human mandibular symphysis concentrates multiaxial loads during function and remodels throughout growth, but the precise mechanisms underlying cortical bone shape during growth remain relatively unexplored. Approaches based solely on thickness or external cortical contours provide only partial insights and do not capture the functional ...

Study on vibration characteristics and tooth profile modification of a plus planetary gear set [PDF]
, 2014 The governing vibration differential equation of a plus planetary gear set has derived from the Lagrange method. Its three often neglected components are considered: [1] the meshing damping, [2] the elastic bearing support of the sun wheel, [3] and the ...

The Anatomical Record, EarlyView.Abstract Fishes of the genus Enchodus were abundant and cosmopolitan in the Late Cretaceous, but are primarily known from isolated remains in Canada. Four well‐preserved fish skulls were recovered in recent years from ammolite mines sampling the Bearpaw Formation of Southern Alberta, and are here referred to Enchodus petrosus Cope, 1874.

Arthroscopy Techniques, EarlyView.Abstract Anterior shoulder instability is common in active patients. Traumatic dislocations may produce Bankart and Hill‐Sachs lesions that increase recurrence risk. In high‐demand individuals, isolated Bankart repair may be insufficient for off‐track or near‐track Hill‐Sachs lesions.

Effect of aesthetic crown lengthening on life quality and self‐esteem: 2‐year study
Clinical Advances in Periodontics, EarlyView.Abstract Background A gummy smile can result from several factors, often leading to a disharmonious appearance and causing physical and psychological discomfort for the patient. This study aimed to evaluate changes in self‐esteem and quality of life for patients, as well as the recidivism rate, following aesthetic crown lengthening (ACL) surgery ...

Perigraftitis, an independent biologic complication associated with implants placed in grafted bone
Clinical Advances in Periodontics, EarlyView.Abstract Background Perigraftitis is a recently introduced concept describing biologic complications specifically associated with implants placed in grafted bone. It is characterized by inflammation resulting from bacterial colonization of grafted bone and/or residual graft particulates.
