Abstract

OBJECTIVESA flapless tissue level minimally invasive technique has been proposed for rehabilitation procedures with implants characterized by a laser modified neck surface. A promising computer-controlled laser microtextured technique which creates an implant neck surface with cell-sized microchannels (8 mu m) has been developed. This preliminary clinical study aimed to evaluate soft and hard tissues modification around implants with laser microtextured neck.MATERIALS AND METHODSTapered tissue level implants, characterized by 2.0 mm laser-treated surface neck were placed in healthy consecutive patients using a flapless technique. After 3 months customized abutments and provisional resin crowns were applied. Definitive metal-ceramic crowns were cemented approximately after 4 months from implant placement. Periapical Rx were taken after 1, 3, 6 and 12 months from placement to evaluate marginal bone level (MBL). Gingival biotype (thin/thick) was measured before surgeries. Plaque score (PS) and Bleeding on probing (BoP) were evaluated on 4 sites (buccal, oral, mesial, distal) at 3, 6 and 12 months follow-up. Dichotomous scores were used (0 = absence, 1 = presence) for both parameters. Gingival biotype (thin/ thick) was also recorded.RESULTSA total of 31 implants were placed in consecutive 26 patients (15 F, 11 M, mean age 61 +/- 8 years). All implants were safe from complications.
