摘要

An 'adhesive bridge' technique permitting the chairside replacement of missing single anterior teeth was evaluated over a 19-month period in 18 subjects. Results indicated that adhesive bridges offered definite advantages in ease o Qf construction, oral tissue compatability, and esthetics, and were of particular advantage to the Navy dentist who is without access to laboratory support. These advantages were offset to a considerable degree, however, by uncertainties in service life of the restoration. Re-examination of the failed bridges showed that delamination occurred at the interface between the pontic and Bis-GMA resin used to cement the pontic to the natural teeth. This consistent site of failure suggested that an effective tie coat between the resin and pontic would improve the success rate for this technique.
