Is soft tissue regeneration critical to implant success?

In recent years there has been a change in the direction of the therapy concept for partially edentulous patients towards an increasing awareness of the significance of dental aesthetics. Although bone remains the soft tissue scaffold, the quantity and quality of the soft-tissue around teeth and implants gains progressively in importance.

Indication: Gain of Keratinised Tissue

Investigators still cannot agree on the importance of the presence of keratinised tissue. Various studies have shown, however, that lack of keratinised soft-tissue around implants and teeth can have negative consequences in both function and aesthetics.1,2

Soft-tissue recession

A recent study has shown that lack of keratinised buccal soft-tissue around implants caused gingival recession over a period of five years.1

Inflammation and attachment loss

There is scientific evidence that the presence of keratinised mucosa has a significant effect on the health and stability of the soft tissue,3,4 while lack of keratinised soft tissue around implants is associated with inflammation and attachment loss.2

Increased plaque accumulation

Patients with a low width of keratinised tissue showed increased plaque lingually and more frequent bleeding at the implant.1

Proven Efficacy

Therapy with Geistlich Mucograft® yields a similar amount of keratinised tissue gain as with either the connective tissue graft5 (CTG) or free gingival graft (FGG).6 In addition, Geistlich Mucograft® provides higher therapy safety for gaining keratinised tissue around implants compared to connective tissue grafting while eliminating the morbidity of a harvest site.5
