Clinical Analysis on Successful Immediate Implant after Extraction: Byung-Rho Chin, Ji Hyun Kim; Yeungnam Univ J Med. 2007;24(2 Suppl):S617-622. Published online December 31, 2007; DOI: https://doi.org/10.12701/yujm.2007.24.2S.S617

Abstract PDF: Immediate implant placement has become an acceptable treatment in dentistry and oral maxillofacial surgery for reducing the treatment period and utilizing extraction socket. From the viewpoint of the healing of extraction socket and periodontology during implantation, integrity of the soft tissue and hard tissue after loss of tooth should be considered. The advantages of the immediate implantation after extraction is prevention of natural buccal or labial alveolar bone loss and is available to healing of extraction socket and osteogenesis. But osteointegration is affected to the defect of soft tissue and alveolar bone after extraction. And healing condition of extraction socket is related to implant-prosthesis treatment and oral hygiene.

Clinical Evaluation about the Immediate Implant Replacement after Tooth Extraction.: Eun Young Yang, Sang Deuk Chun, Jae Hwan Rho, Seung Eun Lee, Jae Chul Song, Byung Rho Chin; Yeungnam Univ J Med. 2003;20(1):45-52. Published online June 30, 2003; DOI: https://doi.org/10.12701/yujm.2003.20.1.45

Abstract PDF: BACKGROUND
Immediate implant placement has become an acceptable treatment for the edentulous area. The advantages of the immediate implant placement include considerable decrease in time from tooth extraction to placement of the finial prosthesis, fewer surgical procedures, and better acceptance of the overall treatment plans. But the success is dependent on the quantity and quality of the extraction socket. The purpose of this study is to evaluate the success of the immediate implant placement. MATERIALS AND METHODS: Twenty-one sites in 16 patients were selected for the evaluation of the immediate implant placement. All of the cases were followed using clinical and radiographic examinations. Criteria of success were the absence of peri-implant radiolucency, mobility, and persistent pain or sign of infection. RESULTS: Of the 21 implants, 13 implants have been succeeded. Of the 13 implants, 10 implants were replaced for the periodontal disease and 3 implants were replaced for the trauma. CONCLUSION: The criteria of the success in immediate implant placement are as follows. 1) Implants placed into fresh extraction sockets have a high rate of survival. 2) Implant should be placed as close as possible to the alveolar crest. 3) Implant placed into available bone beyond the apex have a high success rate.
