Surgical Procedure For Dental Implant Treatment

Surgical Procedure For Dental Implant Treatment
Over the years, teeth implants have become a popular option for restoring missing teeth, mainly because of their high durability, longevity and convenience. Dental implants are small inserts made from biocompatible materials, which are surgical placed in the jawbone to support prosthetic teeth. They are available in different lengths, widths and shapes, to suit the requirements of different patients. As the biocompatibility of a teeth implant allows it to osseointegrate with the jawbone, they do not come loose, slip off or cause discomfort, in the way dentures might.
Teeth implant treatment is a simple procedure, which can be usually performed after applying a local anaesthetic. However in some cases, such as when a patient is suffering from dental phobia, the dental implantologist may suggest conscious sedation or general anaesthesia to make the patient feel more comfortable.

The surgical procedure for placing teeth implants requires that the bone first be prepared with a precision drill or a hand osteotome, before the implant is fitted into it. This is followed by a period of healing, spanning a few months, during which the bone integrates with the implant. After this process is satisfactorily complete, prosthetic crowns will be attached to the implants.
A pilot hole is carefully bored into the recipient bone at the edentulous site, taking care to avoid contact with vital structures, such as the inferior alveolar nerve or the mental foramen. This is because these structures are very sensitive, and could cause extreme pain if touched.
The pilot hole is then widened using progressively larger drills. Usually, most dental implantologists prefer using about three to seven successive drilling steps, depending on the length and width of the teeth implant.4.    In most cases, the pilot hole will be around 1mm deeper than the implant being placed, due to the shape of the drill tip. The dental implantologist must consider this extra length, especially while drilling in the vicinity of vital structures like sensitive nerves.
While the hole is being drilled, precautions are usually taken to ensure that the osteoblast or bone cells are not damaged by overheating. This generally involves the use of a cooling saline or water spray to keep the bone temperature below 47 degrees Celsius (or about 117 degrees F).
The metal or ceramic implant is then fitted into place at a precise torque, so that the surrounding bone is not overloaded. This is because overloaded bone may die, resulting in a condition called osteonecrosis, which may lead to failure of the implant to successful fuse with the jawbone.
