Abstract
In patients with severe peridontitis, lower incisors are prone to terminal breakdown. This study assessed the longevity of composite-bonded resin/natural teeth (reinforced only with a stainless steel mesh) as replacements for periodontally lost lower incisors. Besides the longevity of the restoration, the periodontal condition of the abutment teeth, and the general satisfaction of the patient were evaluated retrospectively via a phone interview, in combination with an analysis of the patient's clinical dental file. The cumulative proportion of survival rate of these composite restorations was 80% after 5 years of function. No statistically significant difference 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. The data seem to suggest that composite bonding of 1 or 2 teeth can be considered a semi-permanent rehabilitation for the replacement of 1 or 2 periodontally lost lower incisors.
