A long-term evaluation of composite-bonded natural/resin teeth as replacement of lower incisors with terminal periodontitis

Background: In patients with were periodontitis, lower incisors are prone t o terminal reakdown. This study assessed the longevity of composite-bonded resin/natural teeth (reinforced only with a stainless steel mesh) as replac ements for periodontally lost lower incisors. Methods: Besides the longevity of the restoration, the periodontal conditio n of the abutment teeth, and the general satisfaction of the patient were e valuated retrospectively via a phone interview in combination with an analy sis of the patient's clinical dental file. Results: The cumulative proportion of survival rate of these composite rest orations was 80% after 5 years of function. No statistically significant di fference was found between the survival distribution of one- and two-pontic bridges (P = 0.66). The abutment teeth demonstrated stable probing depths and a negligible loss in attachment (0.1 mm/year). The satisfaction ratings were also favorable. Conclusions: The data seem to suggest that composite bonding of 1 or 2 teet h can be considered a semi-permanent rehabilitation for the replacement of 1 or 2 periodontally lost lower incisors.
