  1. To investigate the hard and soft tissue adaptation and maintenance to the Laser-Lok® microchannels permanent abutment/ new Laser-Lok® implant assembly by performing clinical and radiographic evaluations.
  2. To investigate the effect of inter-implant spacing (minimum of 2 or 3 mm) on hard and soft tissues.
  3. To perform clinical and radiographic evaluations on these abutment/implant assemblies up to 2 years.

Accepts Healthy Volunteers:   Yes

Inclusion Criteria:1. Male or female, between 20-70 years of age, who request dental implant treatment options for rehabilitation.

2. Subjects who are willing to sign an informed consent, participate and return for follow-up visits.

3. Subjects without significant medical history and currently not on medications that might complicate the results.
