Thumb and digit-sucking habits or non-nutritive sucking are considered to be the most prevalent among oral habits. Most children stop thumb sucking on their own. If the habit continues beyond 3 to 4 years of age, it not only affects the dental occlusion, but the shape of the thumb/digit may be altered as well. This article presents the management of thumb sucking by modified RURS, elbow guard incorporated with revised ‘three-alarm’ system.How to cite this article: Shetty RM, Shetty M, Shetty NS, Deoghare A.

There was a definite variation in the thickness of the die spacer with all the three brands and at various points on the die. Two coat thicknesses were found to be in the range of tolerance of 20-40 microns. Thickness at occlusal groove was noted to be the maximum with least at occlusoaxial line angles. Thickness also showed a very significant increase when bottles were stored for a period of three to six months and then applied.

Abstract:Dental implant therapy is a fast growing and brightest prospect in the rehabilitation of completely and partially edentulous arches. Study of implants has become indispensable and so is the biomechanics related to dental implant therapy. Implant abutment connection is a crucial synapse between the implant and the abutment. It is an important determinant of the strength and stability of an implant supported restoration, and play a major role in the success of the implant. The review describes the biomechanics of this crucial connection.
