Selecting the precise implant site

Article Abstract:

A method of three-dimensional imaging of the mouth is described for determining the best site for an endosteal implant (a metal post or similar structure inserted into the jaw to anchor a corrective or prosthetic device). Software is available to analyze the results of scanning carried out by computerized tomography (an X-ray technique that creates very sharp images); the results of such analyses are then converted to measurements suited to the patient's mouth. The technique allows the implant to be placed where there is the best volume of bone, as well as the determination of the best type of implant. Images from scans of the mouth of a 63-year-old man who needed four implants are displayed. The patient's treatment plan is briefly outlined. The author and colleagues have carried out 224 implants using three-dimensional imaging, all of which have been successful. (Consumer Summary produced by Reliance Medical Information, Inc.)

How occlusal forces change in implant patients: a clinical research report

Article Abstract:

Tooth alignment may change after the insertion of dental implants, which may place excessive force on the teeth during biting or chewing. Researchers followed 100 dental implant patients to study changes in the relationship between the upper and lower teeth. Within 18 months after implant insertion, 46% of patients had altered tooth alignment. The dentist had to grind these patients' teeth to balance the intraoral biting and chewing forces. Almost one-third of the dentist's adjustments were made within the first six months after the implants were placed. In most cases, adjustments were made to the dental implant rather than to the natural teeth. The tooth alignment usually stabilized after one adjustment. Changes in tooth alignment may cause early implant failure.

Implant failures associated with asymptomatic endodontically treated teeth

Article Abstract:

The authors discuss the reasons why implanted teeth failed to remain useful, among them, being adjacent to teeth with infection. These case histories discuss implants next to teeth which showed infection, but still failed in the same way.
