Schwarz F, Mihatovic I, Ferrari D, Wieland M, Becker J. 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. J Clin Periodontol 2010; 37: 551–562. doi: 10.1111/j.1600‐051X.2009.01568.x.Abstract 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. 1 × , 2 × , 3 × , and 4 ×). Histomorphometrical analysis (e.g. mucosal margin (PM) – apical extension of the junctional epithelium (aJE), PM – coronal level of bone‐to‐implant contact (CBI) was performed at 4, 8, 12, and 24 weeks. Results: While M and SLA groups revealed a split formation, epithelial cells and connective tissue were in close contact to modA and modSLA surfaces. Frequent clinical probing (i.e. 3 × and 4 ×) increased mean pocket depths, PM‐aJE, and aJE‐CBI values in all groups and markedly disrupted the epithelial and connective tissue attachment. Conclusions: It was concluded that irrespective of the surface characteristics, a frequent clinical probing at short intervals during the healing phase was associated with dimensional and structural changes of the mucosal seal.
