Materials and methods : Clinical and radiographics results at 3 years of RCT with split-mouth design of submerged vs. nonsubmerged single laser-microgrooved implants in posterior areas [1]
This randomized clinical trial included 20 patients, 12 males and 8 females, between the age of 36 and 64 (mean age of 49.7 ± 12.3 years), who were partially edentulous and needed implants for rehabilitation with a single tooth/implant of two non-adjacent sites. Patients were consecutively enrolled between January and July 2014. The study was approved by the Institutional Ethics committee of La Sapienza University, Rome, Italy, (#4597), and was conducted according to the principles outlined in the Helsinki declaration for biomedical research involving human subjects.

Inclusion criteria were age ≥ 18 years, good general health, and without contraindications to implant surgery. Exclusion criteria were implants placed into regenerated bone or with grafting/regenerative procedures, lack of a periodontal chart and periapical radiograph at the beginning and at the end of the follow-up period, alcohol and drug abuse, pregnancy, or uncontrolled metabolic disorders, tobacco smoking (> 10 cigarettes/day), full mouth plaque score (FMPS), and full mouth bleeding score (FMBS) ≥ 25%, periodontally compromised patients (with attachment loss ≥ 3 mm and/or radiographic bone loss ≥ 30% of root length in ≥ 30% of sites), teeth adjacent mesially and distally to the implant area affected by untreated periodontal, and/or endodontic infections.
Two implants were used:
Tapered Internal Laser-Lok® implant (BioHorizons, Birmingham, AL, USA) with laser microgrooved in the range of 8 μm intramucosal design, 3.8 mm and 4.6 mm in diameter and length between 9.0 and 12.0 mm (Fig. 1).
Tapered Tissue Level Laser-Lok® implant (BioHorizons, Birmingham, AL, USA) with a laser microgrooved in the range of 8 μm intramucosal design and a 1.3 mm machined metal collar, 3.8 mm and 4.6 mm in diameter, and length between 9.0 and 12.0 mm (Fig. 2).
Both implants had the same body tapered macro design, the same resorbable blast textured surface, and buttress thread. Laser-produced microgrooves are a series of cell-sized parallel, linear, and circumferential isotropic channels (Fig. 3 on the right).
