Combined surgical procedures have been introduced that combine periodontal regenerative/reconstructive procedures in intrabony defects with a connective tissue graft to compensate for a deficient bone wall and limit soft tissue shrinkage, but little is known about the reproducibility of these advanced surgical techniques. This 12-case series applies a combined surgical procedure, combining amelogenins, bone substitutes, and connective tissue graft to treat deep intrabony defects associated with gingival recession. Twelve deep intrabony defects with a mean clinical attachment loss of 9.9 ± 2.1 mm, mean probing depth (PPD) of 7.8 ± 1.5 mm, mean recession of the tip of the interdental papilla (TP) of 2.1 ± 1.5 mm, and mean buccal recession (REC) of 2.3 ± 1.8 mm were treated. At 1 year, the average attachment gain was 5.1 ± 1.8 mm (P < .001), the residual PPD was 2.9 ± 0.7 mm (P < .001), no change was observed in the TP (-0.4 ± 0.8 mm, P = .078), and the REC slightly decreased to 1.7 ± 1.5 mm (P = .047). These results suggest that the proposed technique led to predictable clinical outcomes that support regeneration while maintaining or improving the position of the soft tissue margin for the interdental and buccal aspects in deep intrabony defects associated with gingival recession.
