The flapless technique uses rotary burs or a tissue punch to gain access to bone without flap elevation, so the vascular supply and surrounding soft tissue are well preserved. The advantages of this type of procedure include less surgical trauma, decreased operative time, rapid postsurgical healing, fewer postoperative complications, and increased patient comfort.1-3

In the following years, some case reports and studies have described various techniques for using minimally invasive approaches for implant placement.8-10 Predictable results including short term implant success rate and soft tissue outcome have been confirmed by some studies with this technique.8-12 In clinic, when the implant site with limited width of KM, minimally invasive flapless surgery seems more useful for obtaining adequate quantity circumferential closure of keratinized tissue around the emerging implant than punch technique. However, there was no randomized clinical trial to evaluate soft tissue response, crestal bone changes and patient subjective assessment between minimally invasive flapless surgery and traditional flap surgery in selected and appropriately planned cases. Furthermore, it is interesting to conduct a study to compare the effective of soft tissue preservation with minimally invasive flapless surgery to traditional flap
