Properties of FRC, such as strength, desirable esthetic characteristics, ease of use, adaptability of various shapes, and potential for direct bonding to tooth structure make it suitable for various applications (Hyeon Kim et al, 2014) The anterior permanent extracted tooth can be directly bonded to the adjacent teeth with the FRC. 8 This non invasive provisional method leads to exact repositioning of the coronal part of the anterior extracted tooth in its origi...

Dental News Volume XXII, Number I, March, 2015 by Dr. Elias Smaira, Dr. Mireille Rahi, Dr. Najib Abou Hamra, Dr. Danielle El Hakim Abstract Periotest values seem to differ between the gingiva former, abutment placement and after single crown cementation on implants. Materials and Methods 28 patients were selected and measurements were taken on 42 implants at the gingiva former level, abutment level and after single crown cementation. Mean values of all stages were then calculated and compared.   Results An increased mean value of 2.7 was noted between the gingiva former and single crown final stages.   Conclusion Positif Periotest values on implant single crown might be considered normal when the healing  abutment measurements range between -3 and 0. Introduction To evaluate  the degree of osseointegration, various methods have been proposed: histology and histophotometry, 1  removable torque analysis, 2  pull...

Dental News Volume XXII, Number I, March, 2015 By Dr.  P. Dhanrajani, and Dr. R. Weld-Moore Introduction The problem of inferior alveolar nerve involvement during surgical procedure of the removal of lower third molars is often a source of litigations 1,2,3 . At the same time the impact of this on a person’s quality of life should not be overlooked. Coronectomy or partial odontectomy reduces the likelihood of nerve injury by insuring retention of the vital roots when they are close or associated with the inferior alveolar nerve as evaluated by plain radiography or CBCT 4,5 . The method aims to remove only the crown part of an impacted mandibular third molar while leaving the root and pulp undisturbed, thereby avoiding direct or indirect damage to the inferior alveolar nerve 6,7,8 . Literature so far has hailed its merits and many practitioners regularly use the approach of coronectomy in order to minimise Inferior alveolar nerve injuries. This techni...
