CASE REPORT Single Stage Immediate Implant Placements in the Esthetic Zone Loong T. Yong* This case series report documents 5 successful cases of immediate implant placements into fresh extraction sockets in the esthetic zone, subsequently restored with favourable outcomes. The case selection, treatment planning, surgical protocol, restorative outcomes are presented and discussed. Key Words: immediate implant, extraction sockets, esthetic zone INTRODUCTION he original implant surgical protocol proposed by Branemark et al1 involves open flap access, stepwise osteotomy of the bony ridge, and implant placement followed by good primary closure. If the patient presents with a failing tooth, extraction must be performed and the socket allowed to heal for 3 to 6 months before replacement with a dental implant can be considered. After complete socket healing has taken place, bony ridge and soft tissue deficiencies that render the site unsuitable for implant placement need to be addressed first. A variety of hard and soft tissue ridge augmentations may be used, but overall treatment time is prolonged. Though a lengthy procedure, this had been a reliable protocol adopted by surgeons worldwide due to its predictable and systematic nature, allowing complications that may arise from each step to be dealt with appropriately.1 However, with technologic advances and new surgical innovations, various radical modifications to this original protocol had been introduced that showed promising and predictable outcomes. One such treatment protocol is the placement of implants into fresh extraction sockets, otherwise commonly known as immediate implant placement.2 Oral and Maxillofacial Surgery, National Dental Center, Singapore. * Corresponding author, e-mail: yongloongtee@yahoo.com.sg DOI: 10.1563/AAID-JOI-D-11-00152 T Immediate implant placement may be defined as implant placement immediately following tooth extraction and as part of the same surgical procedure,2 or as implant placement immediately following extraction of a tooth which must be combined in most patients with a bone-grafting technique to eliminate peri-implant bone defects.3 This technique has a number of proposed advantages such as preservation of bone and soft tissue, decreased total treatment time, reduced number of surgical procedures, reduced overall cost, and better patient acceptance.3,4 However, discrepancies between the size of the implant and sockets, poorly vascularized infected bone at the implant site, difficulty controlling 3dimensional implant position, and primary stability are some of the surgical challenges that operators face.4 Therefore, this unique procedure is generally not recommended for the novice surgeon. This article presents a case series of immediate dental implant placements into fresh extraction sockets in the esthetic zone by a single oral and maxillofacial surgeon. The case selection, treatment planning, surgical protocol, and restorative outcomes are presented and discussed. MATERIALS METHODS AND Patients This series reports 5 consecutive cases out of 8 seen and treated by a single oral and maxillofacial surgeon from the Department of Oral and Maxillo- 738 Vol. XXXVIII /No. Six /2012
