CLINICAL EVALUATION OF AN ACRYLIC PONTIC "ADHESIVELY" BONDED TO UNCUT ABUTMENT TEETH: 18 MONTH RESULTS by

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 of construction, oral tissue compatability, and esthetics, particularly to the Navy dentist 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 mode of failure suggested that an effective "tie coat" between the resin and pontic would improve the success rate for this technique.
