Past literatures stressed that when a gap occurred between smooth surface implant and alveolar bone, osseointegration was unsatisfactory at histologic examination regardless of clinical findings. Accordingly, standard surgical approach in the early days of implant surgery was to place the implant after all gap was healed. However, Botticelli et al.(2004) reported high degree of osseointegration at the gap with SLA surface implant. From then, the era of immediate implantation has begun because SLA surface implant make gap healing possible. There are two main disadvantages of immediate implantation: (1) surgical technique is sensitive for primary implant stability, (2) Implant placement at the accurate position that predicts external change of extraction wound is required. Immediate implantation has outstanding advantages in all perspectives except for the above-mentioned disadvantages. Therefore, it would be unwise to abandon the option of immediate implantation simply due to surgical difficulties. The purpose of this paper is to describe the necessity of immediate implantation and to present scientific evidence for immediate implantation and accurate implant position by literature review.

Thin labial plate will be resorbed after extraction. Immediate implantation cannot prevent soft and hard tissue loss. Bone graft can be necessary in the immediate implantation after anterior tooth extraction. Slowly-resorbed or non-resorbable bone graft material have many advantages in esthetic area because of maintenance of volume. The clinicians should select the adequate cases of immediate implantation according to the indication and contraindication.

In the recent studies, many authors have reported that the success rate of immediate implantation has no difference compared to conventional staged implantation. Although the immediate implantation has many advantages over conventional approach, many clinicians don't seem to practice because they think that most of the extraction sockets will have some bony gab with defects around implant and that this situation makes the result of immediate implantation unpredictable. We clinically analyzed 23 implanted sites of 18 patients treated with immediate implantation in our hospital from September 2003 to January 2004. The $ITI^{(R)}$. dental implant system was used and GBR procedure with $Bio-Oss^{(R)}$. and $Bio-Gide^{(R)}$. was done simultaneously. The pre & post-op. measurements were recorded such as alveolar crest-adjacent tooth CEJ distance, gingival crest-adjacent tooth CEJ distance, existence of periapical lesion, vertical defect around the extraction socket, horizontal defect around the extraction socket, probing depth, radiologic change of alveolar crest height. We report a positive outcome about immediate implantation with review of literatures.

Successful osseo-integration of dental implants that Dr. Bronemak reported in 1965 had been ground-breaking research in the restorative dentistry for the missing dentition. Clinical application of dental implants in the restorative dentistry has begun with the role of retention and support for the complete denture, beyond the functional recovery in partially missing area, and succeeds in the cosmetic recovery for anterior missing area. Recently, immediate implantation and loading after the extraction have been preferred by many excellent clinicians especially on maxillary anterior missing area, because they want to prevent from the absorption of residual alveolar bone. But it is hard to decide immediate loading for common clinicians also, because it is difficult for them to convict proper osseo-integration. In this article, immediate implantation and delayed loading case on maxillay anterior region have been introduced and predictable prosthetic procedure for the esthetic result has suggested.

상악 전치부는 심미적 회복이 강조되는 부위다. 발치 후 치유될 때까지 기다린다면 치조골 흡수와 치간 유두 수축을 방지할 수 없다. 일단 흡수된 조직을 재생하기 위해서는 추가적인 외과적 술식이 필요하고 치료 기간도 많이 소요된다. 발치 전 치조골과 치은 조직이 건강하다면 치주 조직을 보존 유지하기 위해 발치와 동시에 즉시 임플란트 식립을 고려할 수 있다. 특히 건전한 발치와에서의 즉시 임플란트 식립은 여러 논문에서 성공적인 결과를 보였다. 치근단 병소가 존재하는 치아의 발치 후 즉시 임플란트 식립에 대해서는 부정적인 반응을 보이는 연구가 많았으나, 최근에는 확실한 발치와의 육아조직제거와 전신적 항생제 투여 시 성공률이 높다는 결과도 보고되고 있다. 본 증례는 73세 여환으로 상악 좌측 중절치의 포스트-코어와 금속도재관이 탈락되었으며 임플란트 치료를 받고 싶다는 주소로 내원하였다. 치근단 병소와 수직적 치근 파절이 존재하였으나 치근단 병소가 있는 치아에서도 즉시 임플란트 식립의 성공사례가 여러 차례 보고되어 발치 및 즉시 임플란트 식립을 계획하였다. 발치 후 발치와 육아조직제거와 클로르헥시딘 용액 소독 및 tetracycline 용액으로 soaking을 시행한 후 임플란트를 식립하였으며 식립 전 후로 전신적 항생제를 투여하였다. 임플란트를 식립하면서 인상채득하여 2일 뒤 임시 보철물을 장착하였다. 약 6개월 뒤 치경부 형태를 재연하여 최종 인상 채득하였으며 최종 보철물을 장착하였다. 보철물 장착 후 2년까지 치은선이 인접치아와 조화를 이루고 변연골 흡수없이 심미적으로 만족할만한 결과를 얻었기에 보고하는 바이다.

Early implantation before sufficient ossification has taken place usually results in osseointegartion failure due to reduced bone-fixture interface area. However, various studies have shown successful osseointegration results following immediate implants concurrently with GTR. The clinical trends have been to shorten the patients' edentulous state by immediate implantation, and reduce the alveolar bone resorption. However, it may be difficult to attain the complete soft tissue coverage of the sites, increasing the chance of infection. Furthermore, there may be more studies needed on the clinical behaviors of e-PTFE membranes, various modofications in the membrane materials and bone graft materials. Various animal and clinical studies have been reported on the successful osseointagration following immediate implantation, but the long-term follow-up studies are limited. The present study investigated 16 immediately-implanted implants with GTR therapy with or without calcium carbonate grafting on 11 patients 3 years after installation and 24-30 months after functional loading. Based on the clinical, radiographic and histologic findings, the following results have been attained. 1. Clinically, stability has been shown on all 16 implants throughout the investigated periods. 2. Radiologically, the alveolar bone loss has progressed up to the polished neck portion but not beyond it, suggesting the progressive osseointegration from the GTR therapy. 3. The GTR method used in the present study is easy to use clinically, and may be appied in the regeneration of ossoeous defects around implants and in the immediate implantation. 4. The difficulty in complete tissue coverage may be avoided by delaying the installation for 2 to 3 weeks after the extraction allowing certain degree of soft tissue healing.

발치 즉시 임플란트는 치료 기간을 단축할 수 있을 뿐만 아니라 여러 가지 장점으로 인해서 치과임상에서 유용한 임플란트 치료법으로 인식되면서 널리 적용되고 있다. 다양한 이유로 인해서 하악 제1대구치의 발치가 필요한 5명의 환자에게 발치 즉시 임플란트 치료를 진행하여 전체 치료 기간을 단축하면서 만족스러운 결과를 얻었다. 발치 즉시 임플란트는 발치와 내 정확한 위치에 적절한 초기고정을 얻어야 하고 주위 연조직도 개선해야 하는 고난도 치료법이지만 임상적으로 매우 유용한 보철 수복 방법이라고 판단된다.

The conventional osseointegration protocol calls for waiting up to 12 months for ossification of an extraction socket to heal before placing an endosseous implant. In this study, the possibility of placing a pure titanium implant directly into an extraction socket immediately after extraction was investigated. And the marginal bone loss of immediate nonsubmerged and submerged endosseous dental implants placed into extraction sockets was also compared. Pure titanium Nobelpharma Branemark implants and solid screw type ITI implants were placed into premolar extraction sockets of two adult dogs and allowed to heal for a period of 3 months, followed by functional loading of the implant. Radiographic examination was performed before implantation, immediately after implantation and 3, 6, 9, 12 months after implantation. The results obtained were as follows : 1. Immediately placed nonsubmerged ITI implants and submerged Branemark implants showed favorable radiographic osseointegration status and there were minimum marginal bone loss. 2. There were no significant differences in radiographic finding of osseointegration between conventional and immediate implantation. 3. Gingival tissue around implants showed more inflammatory signs than that of adjacent natural teeth. This study suggest that pure titanium Branemark implants and submerged ITI implants have the potential to integrate when placed immediatly after extraction of the teeth and warrants further investigation.
