PubMed ID (PMID): 22292148Pages 187-193, Language: EnglishTinti, Carlo / Parma-Benfenati, StefanoThis article describes a soft tissue surgical modification-the trap door technique-used to enhance contemporary patient esthetic expectations and preserve periodontal health longitudinally. This surgical modification is greatly indicated for single-stage single and multiple implant surgery to preserve the integrity of the papillae and eliminate buccal soft tissue concavity. This procedure also addresses the issue of interproximal papillary development to obviate the presence of a black triangle. The technique is very effective in cases of minimal interproximal bone loss, it does not require autogenous bone harvesting, and is therefore less invasive and well accepted by the patient.
