abstract introduction. the study for beauty can be traced back to the earliest civilizations. many factors influence the perception of beauty, and esthetic dentistry continues to grow as a major part of overall dentistry. one of the most important factors in beauty of the teeth is the proportion of them to one another, and golden proportion is determined to be 1.618. the purpose of this study w...
متن کاملLong-term stability: postretention changes of the mandibular anterior teeth.
INTRODUCTION Our objectives were to evaluate the long-term posttreatment changes of orthodontically corrected mandibular anterior malalignment and to determine the factors explaining these changes. METHODS The sample consisted of 66 subjects (mean age, 15.4 ± 1.7 years) selected from 7 private practices. The teeth had been retained for approximately 3 years and followed for 15.6 ± 5.9 years p...
متن کاملRestoring primary anterior teeth.
A variety of esthetic restorative materials are available for restoring primary incisors. Knowledge of the specific strengths, weakness, and properties of each material will enhance the clinician's ability to make the best choice of selection for each individual situation. Intracoronal restorations of primary teeth may utilize resin composites, glass ionomer cements, resin-modified ionomers, or...
متن کاملChewing stress developed in upper anterior teeth with root end resection. a finite element analysis study.
AIM Because pulpless teeth have a higher risk of vertical root fracture, the present study investigated the additional effect of root end resection upon their mechanical resistence. METHODS Finite element analysis (FEA) was used to evaluate the stress and deformations of upper anterior teeth after root end resection while loading them at 100N and 300N. RESULTS Loading teeth with root end re...
متن کاملHomologies of the Anterior Teeth in Indriidae
Schwartz ('74) proposed revised homologies of the deciduous and permanent anterior teeth in living lemuriform primates of the family Indriidae. Gingerich ('77) described a juvenile specimen of Avahi and emphasized the importance of functional integrity in controlling the pattern of dental reduction in primates, neither of which supports Schwartz's interpretation. Schwartz ('78) recently reitera...
