CONTEXT This article presents an original research conducted at Government Dental College, PGIDS, Rohtak. AIMS (1) To evaluate the marginal bone level changes around dental implants based on the radiological examination. (2) To evaluate the relationship of various parameters, i.e., gender, implant length, implant diameter and location of implants on the(More)
In past, the materials used for denture bases were vulcanite, celluloid & phenol formaldehyde. Acrylic resins were introduced to dentistry in 1930’s. There are certain limitations of acrylics like residual monomer allergy, poor mechanical strength, low fatigue strength, brittle on impact, poor conductors of heat, low hardness, high coefficient of thermal(More)
Osseointegration of dental implants refers to the process of bone growing right up to the implant surface. No soft tissue connects the bone to the surface of the implant. No scar tissue, cartilage or ligament fibers are present between the bones and implant surface. The direct contact of bone and implant surface can be verified microscopically. When(More)

Implant placement into the posterior maxilla often creates a challenge due to inadequate bone height because of close sinus proximity. This article presents a case report of indirect sinus lift technique involving hydraulic pressure to elevate the floor of the maxillary sinus.
DSR has made a significant improvement in the detection of dental & maxillofacial lesions. The Digital Subtraction Radiography is used to compare standardized radiographs taken at sequential examination visits. All unchanged structures are subtracted and these areas are displayed in neutral gray shade in the subtraction image; while regions that have(More)
Ascorbate (vitamin C) is a cofactor for a number of metabolic enzymes and is an indisputable essential vitamin C for humans.
