Flapless or stitchless surgery is a noninvasive way of placing dental implants. This is a kind of dental implant surgery in which there is no need to lift [reflect] gingival flap [gums] tissue, and dental implant is placed through a small window [hole] in gum [soft tissue].
The main advantages of the flap less surgeries are as follows
Atraumatic & less invasive procedure
No need to cut the gum tissues
No need to take the stiches [sutures]
Immediately after teeth [crowns] can be made
Chances of complications & post operative pain are almost nil
Cosmetically gives best soft tissue results
Post operative bone loss is minimal
Excellent soft tissue - Implant seal is achieved
Patient can immediately join the routine
But at the same time it requires very precise surgical technique and only very highly skilled & trained implantologist should attempt flapless surgeries.
