Problem solving in implant dentistry

Article Abstract:

Some of the most important problems that dentists who perform dental implantation may face are briefly discussed. Prevention of problems is the first priority; this involves a careful initial examination of all structures within the patient's mouth. The type of implant, which will serve as an anchor for artificial teeth, must be appropriate to both the implant site and the prosthetic device it will ultimately support. Suggestions are made regarding optimal methods of tooth removal, leading to minimal bone fracture and soft tissue loss. Teeth retained that are not completely healthy can undermine the success of implants. Careful attention to surgical protocols will prevent the majority of implant failures. Attention to the healing process after implantation is essential, as is thorough examination to detect any complications prior to the second stage of surgery (by which time the implant should have become integrated into bone). The prosthesis (artificial tooth) should fit properly into the implant, with enough space available that hygiene can be maintained. Patients must expect to wait several weeks, perhaps as long as four months, until they can resume normal function. Since bone is a dynamic medium, subject to constant remodeling, the bone-implant interface is always in a state of tension; patients need instruction in maintenance of this equilibrium. Criteria for removal of the implant includes inflammation, mobility, and discharge problems. The best guard against implant failure is a good preventive program, which saves more implants than rescue operations can. (Consumer Summary produced by Reliance Medical Information, Inc.)

Nonsurgical management of ectopic teeth

Article Abstract:

Ectopic teeth are teeth that are located in an abnormal position, and problems can arise during their growth. Since the alveolar bone (bone socket) in which the tooth grows is connected to the supporting bone of adjacent teeth, dental procedures performed on the ectopic tooth can affect other teeth as well, making a nonsurgical approach desirable. Four case histories of young patients with ectopic teeth are presented. In two cases, springs were used to make a space between two teeth so the ectopic tooth could grow into the correct position. However, the use of mechanical force can cause chemical changes in the bone. Two other patients underwent surgical treatment; in one case the surgery was followed by use of an elevator (an instrument used as a lever to remove bone). These cases were monitored for over 25 years the outcomes indicated that aggressive surgical treatment causes several problems, including effects on adjacent teeth, bone resorption (loss), and unwanted effects on tooth movement. Problems with ectopic teeth should be solved with close collaboration between orthodontist and surgical personnel to ensure consideration of all possible sequelae.

The effect of a triclosan/ copolymer/ fluoride liquid dentrifice on interproximal enamel remineralization and fluoride uptake

Article Abstract:

The performance of enamel remineralization of dental interproximal surfaces by a triclosan/ copolymer/ fluoride liquid dentrifice is examined. The new liquid dentrifice is recommended for patients prone to developing interproximal carious lesions.
