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.
