- •Age 25 - 50 years.
- •No intraoral soft tissue or hard tissue pathosis.
- •No systemic condition contraindicating implant placement.

研究组 & 干预措施
Expansion by Densah bur
- Scrubbing and draping of the patient in a standard fashion for intra oral procedures followed by local anesthesia administration to the patient.
- A mid crestal flap will be reflected.
- For both groups the implant manufacturer's pilot drill will be used to perform a standard osteotomy of 10 mm depth.
- Sequential use of Densah bur under copious irrigation.
- An implant of 3.9*10 mm will be inserted.
- Smart peg will be placed on implant and Osstell will be used to record ISQ.
- Healing collars will be placed on implants.
- Flap will be prepared for closure and suturing.
干预措施: Expansion (Other)
