Intracoronal precision attachments.

Abstract

Intracoronal precision attachments provide part of the basis for the development of physiologic partial dentures. While the prefabricated and laboratory-fabricated attachments both have advantages and disadvantages associated with their use, both can be successfully utilized in partial denture construction. The final choice should be made taking all factors, physical and biological, into consideration. The author has personally utilized the laboratory-fabricated attachment almost exclusively over the last six years of private practice. Clinically, the results obtained have equaled, and in many instances surpassed, those which had been obtained with commercially available intracoronal attachments. If the requisite laboratory support for the construction of the laboratory-fabricated attachment is available, the practitioner is urged to try this method himself.

The new removable denture patient: treatment procedures.

Dentists are beginning to see a new type of patient who requires removable prosthodontic rehabilitation. These patients are the result of both increases in longevity and dental treatment that has retained teeth, despite the onslaught of caries and periodontal disease. The current procedures for transitioning patients into removable prostheses can be modified for this new group of patients. This article presents a transition procedure for patients who are receiving removable prostheses, which dissociates the surgical phase of treatment from the prosthetic stage. The patient's existing teeth are incorporated into a removable prosthesis in a way that ensures the exact replication of the tooth position in the oral cavity. This method addresses many of the inadequacies of current procedures while at the same time requiring a minimum of chair time. Even with this procedure, this transition is still difficult for the patient.

Retention of prefabricated attachments for implant stabilized overdentures in the edentulous mandible: an in vitro study.

STATEMENT OF PROBLEM: Bar and stud attachments are widely used to stabilize overdentures on implants in the mandible. There is strong evidence that retention of the attachment is an important factor for a patient's satisfaction. PURPOSE: This study describes retentive forces and wear of commercially available attachments of 4 implant systems (31, IMZ, Nobel Biocare, ITI Straumann) and 2 magnets (Steco). METHODS: Forces while removing the keyway portion of an attachment in its path of insertion were measured with a platform load cell. A total of 15,000 removals were performed to simulate fatigue. RESULTS: Retentive forces ranged between 3 and 85 N. The fatigue test revealed an initial increase of forces with some attachments. After 15,000 cycles, most of the attachments showed little loss of retention compared with the initial retentive forces. It is suggested that conventional fatigue tests with application of axial loads do no simulate clinical fatigue adequately.
