All patients who meet the inclusion/ exclusion criteria will be consecutively enrolled in the trial. Each participant will be randomly assigned to receive either the plasma activated implants or Non-activated SLA implants by using a computer generated random number table. Allocation concealment will be achieved by means of a Sequentially numbered, opaque, sealed envelope (SNOSE) technique. The surgical procedures for allocated patients will be done in Department of Periodontology.

Routine Blood parameters will be checked pre-operatively (vitamin D3, BT, CT, PTT, CBC, INR) at central lab in “G” block which is a regular protocol for patients undergoing periodontal therapy. Oral prophylaxis will be performed. CBCT will be taken to assess the bone density.

A clinical proforma will be used to document the history, medical and dental anamnesis and clinical parameters (viz) Oral Hygiene Index-Simplified (OHI-S) (Greene & Vermillion,1964), Modified gingival index for dental implants(Mombelli et al), Modified plaque index for dental implants( Mombelli et al, 1987), edentulous site parameters (MD width, WOKG, occlusal clearance, soft tissue thickness) and radiographic parameters (assessed by CBCT) bone quality and quantity, width and height. The surgical procedures will be done as follows 

Under local anaesthesia, (mixture of 2% lignocaine and 1:100,000 adrenaline) either a mid-crestal or paracrestal incision will be made with a 15c blade and BP handle No 3. A mucoperiosteal flap will be elevated and an osteotomy site will be prepared using a standard sequential drilling protocol, followed by the equi-crestal placement of an implant of suitable diameter. Before placement the implant will be irradiated with Plasma for 20 seconds using the Plasma activator (Test group). In control group SLA implants (no activation) will be placed into prepared osteotomy site. Then the stability of the implant will be assessed using an Ostell device, which employs resonance frequency analysis to provide ISQ values ranging from 1 to 100. Cover screws will be subsequently placed over the implant, and the flap will be closed with 3-0 PTFE sutures to achieve hemostasis. Impression will be made at the implant level using impression coping and custom trays, after which the permanent crowns were crafted and cemented onto the abutments. Oral hygiene instructions will be consistently emphasized throughout the study period. Patients will be recalled at 10 days and 1 month for professional oral hygiene and review; at 4 months for implant placement
