Management of perishing implants with abutment screw fracture - A systematic review.

Aim: To systematically review the reported techniques, for evaluating the risk and difficulty encountered in the management of fractured abutment screw in accordance with the location of fracture, and to develop a logical sequence in managing an implant abutment screw fracture.

Settings And Design: Systematic review following PRISMA guidelines.

Materials And Methods: A systematic search of the PubMed/MEDLINE database for articles published between January 2000 and March 2020 was performed by 2 independent reviewers.

Comparison of Cameriere's and Demirjian's methods of age estimation among children in Kerala: a pilot study.

The aim was to compare age estimation using Cameriere's and Demirjian's methods to chronologic age in children with mixed dentition in a rural population of Kerala. The present study comprised of 10 subjects of age range 7-12 years. Dental age was assessed using Cameriere's and Demirjian's methods and was compared to the chronologic age.

A comparative evaluation of the marginal adaptation of a thermoplastic resin, a light cured wax and an inlay casting wax on stone dies: An study.

Background: Different pattern materials do not produce copings with satisfactory, marginal accuracy when used on stone dies at varying time intervals.

Purpose: The purpose of this study was to evaluate and compare the vertical marginal accuracy of patterns formed from three materials, namely, thermoplastic resin, light cured wax and inlay casting wax at three-time intervals of 1, 12, and 24 h.

Methodology: A master die (zirconia abutment mimicking a prepared permanent maxillary central incisor) and metal sleeve (direct metal laser sintering crown #11) were fabricated.

Titanium dioxide as an osteoconductive material: an animal study.

The purpose of the present study was to evaluate the biocompatibility and osteoconductive potential of pure and pigment forms of titanium dioxide. Pure and pigment forms of titanium dioxide were incorporated into prepared bur holes in the femur bone of rabbits. Implantation was done on six Albino rabbits which were sacrificed at the end of 3rd, 4th and 5th months after implantation.
