Implant-Gingival Unit Stability Around One-Stage Implant with Laser-Microgrooved Collar: Three-Year Result of a Prospective Study.

Implant-Gingival Unit Stability Around One-Stage Implant with Laser-Microgrooved Collar: Three-Year Result of a Prospective Study. Int J Periodontics Restorative Dent. 2019 Nov/Dec;39(6):875-882 Authors: Guarnieri R, Di Nardo D, Gaimari G, Miccoli G, Testarelli L Abstract The aim of the present prospective study was to evaluate the stability of peri-implant soft tissue and the stability of the implant-gingival unit (IGU) around one-stage titanium implants with a laser-microgrooved collar surface following 3 years of loading. Thirty one-stage titanium implants with a laser-microgrooved collar surface were placed in 30 partially edentulous patients. Clinical and radiographic examinations were carried out at implant placement, after a period of 4 to 6 months free of masticatory loading, and after 3 years of function. Plaque Index (PI), modified sulcus bleeding index (SBI), probing depth (PD), distance between the implant coronal margin and the mucosal margin (DIM), clinical attachment level (CAL), and keratinized tissue width (KTW) and thickness (KTT) were recorded. Radiographic marginal bone levels (MBL) were assessed at the mesial (MI) and distal (DI) aspects of implant sites. In addition, the influence of KTT on IGU stability was investigated. No implants failed during the follow-up period. Compared to baseline, PI, BPI, PD, DIM, CAL, KTW, MBL, and IGU showed differences that were not statistically significant (P > .05). Moreover,...
