Influence of frequent clinical probing during the healing phase on healthy peri-implant soft tissue formed at different titanium implant surfaces: a histomorphometrical study in dogs.

Objectives: To investigate (i) the impact of different titanium implant surfaces on soft tissue integration over 6 months, and (ii) the influence of frequent clinical probing during the healing phase on the established mucosal seal.

Material And Methods: Standardized clinical probing was randomly performed (12 dogs, probing versus control) at different transmucosal surfaces [machined (M), sand-blasted/acid-etched (SLA), and chemically modified acid-etched (modA), modSLA] at 2, 4, 8, and 12 weeks (i.e.

Surgical regenerative treatment of peri-implantitis lesions using a nanocrystalline hydroxyapatite or a natural bone mineral in combination with a collagen membrane: a four-year clinical follow-up report.

Objectives: The present case series aimed at investigating the 4-year clinical outcomes following surgical regenerative therapy of peri-implantitis lesions using either a nanocrystalline hydroxyapatite (NHA) or a natural bone mineral in combination with a collagen membrane (NBM+CM).

Materials And Methods: Twenty patients suffering from moderate peri-implantitis (n=20 intrabony defects) were randomly treated with (1) access flap surgery (AFS) and the application of NHA (n=9), or with AFS and the application of NBM+CM (n=11). Clinical and radiographic (R) parameters were recorded at baseline (R) and after 36 and 48 (R) months of non-submerged healing.
