Background: Gingival esthetics around dental implants have become a main focus for clinicians. This study analyzed the surgical, prosthetic, and anatomic factors involved in the management of peri-implant tissues. Methods: Forty-eight subjects with one tooth scheduled for tooth extraction and immediate implant placement were in- cluded in the study. After healing, the implants were restored with single-crown ﬁxed prostheses. The following parameters were assessed after 12 months: presence/absence of the inter-proximal papilla, interimplant–tooth distance (ITD), distance from the base of the contact point to the interdental bone (CPB), and soft tissue biotype. ITD and CPB values were de- rived from computer analysis of periapical radiographs. A statistical analysis determined the effect of ITD and CPB on the presence of the interproximal papilla. Results: Papilla was signiﬁcantly present (P <0.05) for ITD of 2.5 to 4 mm in anterior and posterior areas and for CPB £7 mm in posterior areas. Thick biotype was signiﬁcantly associated (P <0.05) with the presence of the papilla. Conclusions: The combination of surgical and prosthetic plans represents the key factor to optimize predictability in single-implant esthetics. The recommended interproximal distance between the implant and the adjacent tooth is 2.5 to 4 mm. The distance from the contact point to the interdental bone is recommended to be <7 mm. Papilla presence is also correlated with a thick gingival biotype.
