2 months. It was found that the mean height of the

“papillae” was 3.4 mm, with 90% of the measure-

ments in the range of 2–4 mm.

The dimension of the soft tissues between adjacent

implants seems to be independent of the implant

design. Lee et al. (2006) examined the soft tissue

height between implants of two different systems

(Brånemark Implant® and Astra Tech Implant®

systems) as well as the potential influence of the hori-

zontal distance between implants. The height of the

inter-implant “papilla”, i.e. the height of soft tissue

coronal to the bone crest measured in radiographs,

was about 3.1 mm for both implant systems. No dif-

ference was found regarding the “papilla” height for

any of the implant systems with regard to sites with

3 mm and≥3 mm in horizontal distance between

the implants. Gastaldo et al. (2004) evaluated the

presence or absence of “papilla” at 96 inter-implant

sites in 58 patients. It was reported that the “papilla”

filled the entire space between the implants only

when the distance from the bone crest to the base

of the contact point between the crown restorations,

assessed by sounding, was4 mm. Thus, taken

together these observations indicate that the soft

tissue between two implants will have a maximum

height of 3–4 mm, and that the location of the contact

point between the crown restorations in relation to

the bone crest level determines whether a complete



soft tissue fill will be obtained in the embrasure space

between two implants (Fig. 3-37).
