The effects of soft tissue punch size on the healing of peri-implant tissue in flapless implant surgeryObjective. Flapless implant surgery using a soft tissue punch device requires a circumferential excision of the mucosa at the implant site. In an attempt to help produce guidelines for the use of soft tissue punches, this animal study was undertaken to examine the effect of soft tissue punch size on the healing of peri-implant tissue in a canine mandible model.Study design. Bilateral, edentulated, flat alveolar ridges were created in the mandibles of six mongrel dogs. After a three month healing period, three fixtures (diameter, 4.0 mm) and healing abutments(diameter, 4.5 mm) were placed on each side of the mandible using 3 mm, 4 mm and 5 mm soft tissue punches. During subsequent healing periods, the peri-implant mucosa was evaluated using clinical, radiological, and histometric parameters, which included Gingival Index, bleeding on probing, probing pocket depth, marginal bone loss, and vertical dimension measurements of the peri-implant tissues. Results. The results showed significant differences (P < 0.05) between the 3 mm, 4 mm, and 5 mm tissue punch groups for the length of the junctional epithelium, probing depth, and marginal bone loss at healing period after implant placement. When the mucosa was punched with a 3 mm tissue punch, the length of the junctional epithelium was shorter, the probing depth was shallower, and less crestal bone loss occurred than when using a tissue punch with a diameter ≥4 mm.Conclusion. Within the limit of this study, the size of the soft tissue punch plays an important role in achieving optimal healing. Our findings support the use of tissue punch slightly narrower than the implant itself to obtain better peri-implant tissue healing around flapless implants.
