Immediate Implantation With Ridge Augmentation Using Acellular Dermal Matrix and Deproteinized Bovine Bone: A Case Report
Immediate implant placement combined with hard and soft tissue grafting has been suggested because it may preclude dramatic postextraction bone loss and may decrease overall discomfort with reduction in the number of surgeries and in treatment time. In this case report, the acellular dermal matrix was used as a membrane for immediate implantation via a bone augmentation procedure in an esthetically challenging situation. The author suggests that this surgical technique provides the clinician with an option for an immediate implant therapy when primary closure is not intended. Additional randomized controlled trials conducted over long periods are necessary to establish whether this procedure offers long-term benefit to patients.

Figure 1. (a) Patient presented with mobile maxillary right central incision. The radiograph showed a fracture line at the apical area of the upper right central incisor. (b) Clinical photograph of the fractured tooth. Figure 2. (a) Dental implant was placed into the extraction socket, and the buccal dehiscence measured 9.5 mm apicocoronally and 7 mm mesiodistally. (b) Deproteinized bovine bone was placed around the implant. (c) An ADM was utilized as a barrier membrane. (d) Incisal view of sutured surgical site shows the exposed ADM.

Figure 3. (a) Labial view shows the maturation of soft tissue after 2 months of provisionalization. The width of keratinized tissues was increased. (b) Incisal view shows that the width of the ridge was well preserved. Figure 4. (a) Final restoration shows good soft tissue response with satisfying esthetic results for the patient. (b) Periapical radiograph of final prosthesis at the time of final evaluation.
