Brief Summary:
  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.

Primary Outcome Measures :
  1. epithelial attachment and bone level around implants [ Time Frame: 2 years ]
    prevent apical migration of the epithelial attachment, and preserve bone level around implant head. radiographic and clinical assessment during recall periods

Secondary Outcome Measures :
  1. inhibit the loss of crestal bone . [ Time Frame: 2 years ]
    preserve the coronal level of bone
