Utilizing Chronic Intrasocket Granulation Tissue for Ridge Preservation: A Novel Approach

Case 1. (a) Clinical situation of #14 and #15. (b) Transverse cone-beam computerized tomographic image. (c) Cross-sectional cone-beam computerized tomographic image of #14. (d) Cross-sectional cone-beam computerized tomographic image of #15. (e) Following extraction, a primary horizontal incision was made on the buccal aspect of the ridge. (f) A flap including intrasocket granulation tissue was elevated. (g) Deproteinized bovine bone mineral was grafted for restoring the ridge contour. (h) Primary flap closure was obtained.

Continued. (i) Healing after 1 week. (j) Healing after 3 weeks. (k) Healing after 4 months. (l) Well-formed ridge contour was observed after flap elevation week. (m) Implants were placed with 1-step underdrilling. (n) A definitive prosthesis was delivered. Yellow arrowhead: primary incision line.

Case 2. (a) Initial clinical situation of #4 and #5. (b) A horizontal incision was made on the palatal aspect of the ridge, and a flap including the intrasocket granulation tissue was then elevated. (c) Deproteinized bovine bone mineral was grafted for restoring ridge contour. (d) A collagen matrix was used for the #5 socket, and flap closure was made. (e) Healing after 1 week. (f) Healing after 10 weeks. (g) Implant placement. (h) Delivery of definitive prosthesis. Yellow arrowhead: primary incision line.

Case 3. (a) Initial clinical situation of #15. (b) Following extraction, thick intrasocket granulation tissue was observed. (c) Primary incision was made on the mesial aspect of the #15 socket. (d) Deproteinized bovine bone mineral was grafted, and primary flap closure was obtained. (e) Healing after 1 week. (f) Healing after 5 months. (g) Implant placement. (h) Delivery of definitive prosthesis. Yellow arrowhead: primary incision line.
