COSMETIC DENTISTRY
Toronto Dental Implants

A typical implant consists of a titanium screw, with a roughened surface.
This surface is treated either by plasma spraying, etching or sandblasting
to increase the integration potential of the implant. At edentulous (without
teeth) jaw sites, a pilot hole is bored into the recipient bone, taking
care to avoid vital structures (in particular the inferior alveolar nerve
within the mandible).
This pilot hole is then expanded by using progressively wider drills. Care
is taken not to damage the osteoblast cells by overheating. A cooling saline
spray keeps the temperature of the bone to below 47 degrees Celsius (approximately
117 degrees Fahrenheit). The implant screw can be self-tapping, and is
screwed into place at a precise torque so as not to overload the surrounding
bone. Once in the bone, a cover screw is placed and the operation site
is allowed to heal for a few months for integration to occur.
